Hardy avocados
Q: I intend to gift three avocados, at least one type A and one type B, to a friend who lives in an area where the temperature never goes below 25F. The idea is to give them a ripening season as long as possible. Which combinations do you suggest, and which are the A and B?
A: When talking about "A" type and "B" type in Avocados, it is referring to the flowers. An avocado will produce both male and female flowers on the same plant. "A" type means that the flowers are female in the morning and male at afternoon. "B" type means that the flowers are male in the morning and female in the afternoon. If you plant to start a commercial growth, then it's important to create a proper mix of both types. However, in hot and humid climate a single tree produces flowers of both types, so it is not necessary to have both A- and B- types planted together in backyard. Even a single tree produces enough fruits for home gardener.
It is also important to know that while there are more cold hardy avocados, it refers to a full grown established tree. They will still need protection from the cold until they are bigger and more established. One can not expect a small tree, which was planted in June, to survive the first winter. It'll take few years until the tree is "harden" enough.
Wurtz Avocado: Fruits from May to Sept.
Dwarf hybrid. It is very compact and slow growing, reaching only about 8-12 feet at maturity. Distinctive weeping growth habit. Suited for planters, containers, patios, greenhouse use. Great for dooryard or container growing. The tree can handle temperatures to 25(F) degrees. Production is good and it is a consistent bearer.
Day Avocado: Fruits July to Sept.
Day avocado is green, smooth skin and is shaped like a club. The fruit is of very good quality and has a nice buttery consistency. The slender tree is relatively cold tolerant and produces July through September.
Fuerte Avocado: Fruits Nov to June.
Relatively cold hardy variety. Green fruit, elongated,flavor excellent, buttery. Vigorous compact tree with decidedly alternate year bearing habit. Ripens November to June.
These three will provide you with fruit ripening during the whole warm season.
For the most cold hardy avocado varieties, see this info sheet.

Full Sun Garden vs Shade Garden
"Someone is sitting in the shade today because someone planted a tree a long time ago." (Warren Buffett)
Q: I live in California and I have a large area of my garden in full shade. Are there any plants that will be happy there? I am looking for something colorful. I also have a smaller area in front of the house that has full sun almost all day long, but I am afraid this can be too hot for flowering plants? Can you recommend something?
A:
Full sun gardens have a strong, bright look while shade
gardens have cooler, subdued appearance. Both types of
gardens are fun to design and maintain as long as you pick
the right plants.
Full Sun Garden is the easiest to grow. Depending
on exposure, it may require some plants that can tolerate
the hottest summer days and the dry conditions in your
area. The good news is, the majority of tropical and
subtropical plants prefer full sun, so you have a large
selection to pick from - fruit trees, flowering trees,
shrubs, vines, and small perennials. The more sun, the
more flowers and fruit you will get! However, keep in mind
that sun gardens require more water, but generous mulching
will help to minimize watering.
Shade Garden is much more restful in appearance,
but sometimes may be a little more difficult to work with.
As shade trees grow bigger and thicker, it may become too
dark; nothing will grow in total darkness. In this case
you need to prune back some branches to let more light in.
Filtered sunlight or dappled light coming through the
leaves of the trees is beneficial and considered light
shade, which would be the best light conditions for shade
loving plants to thrive. Although shady cooler spaces
attract more insects and will require more attention to
control them, they also have some advantages over sun
gardens. You can enjoy working in cooler conditions, and
your garden will require less water. Many foliage plants
look more deeply colored and healthier than in full sun;
white flowers shine instead of looking washed out!
Our favorite shade plants are fragrant brunfelsias , clerodendrums, and of course
colorful gingers and heliconias. You
may also consider ornamental foliage of Calatheas, lush Alocasias, Colocasias, and colorful Cordylines. Check out our shade loving plant list for
more colorful suggestions. These are also great for indoor
gardens!

Avocado, Lychee and Mango setting fruit... give them some FOOD!
Q: Do I need to fertilize tropical fruit when they set fruit?
A:
It is traditionally believed that mango and other tropical
fruit shouldn't be fertilized during fruiting period. It
is true to an extent: you don't want fruit to burst from
fast excessive growing. Instead, try to feed fruit trees
wisely, because they still need proper nutrition to
produce flowers and fruit.
Our spring specials of Lychee, Avocado and Mango are full of buds and
some already set tiny fruit (see examples on the photo).
Here is the feeding plan for these plants once you receive
your mail order:
1) Once received the plant, pot it into container size of
the root ball and let establish for couple weeks. Use SUNSHINE-E to help the plant
recover from shipping stress and establish root system.
2) Apply SUNSHINE-Honey right before
flowering, and next time at setting fruit, to provide
sweeter and bigger fruit, eliminate fruit cracks and help
resist fungus and other fruit diseases.
3) Use balanced granulated fertilizer,
1 tsp per each gallon of soil. Apply once a month during
Spring-Summer season. This gives the plant balanced
macro-elements (NPK) necessary for overall plant health.
Do not use on fruit trees fertilizers with high Nitrogen
content.
4) Apply SUNSHINE SuperFood
micro-element booster to keep fruit trees vigorous,
develop strong root system and avoid deficiencies.
5) In case of signs of chlorosis (yellowing leaves with
darker veins), give the tree SUNSHINE-GreenLeaf and watch
the leaves turning green quickly.
After harvesting, don't forget to make another treatment
of SUNSHINE-Honey as a
preparation for the next year flowering and fruiting
season.

Q: I live in California and about a month ago ordered several plants from you, including fruit trees (Carambola, Mango, Avocado) and flowering trees (Xanthostemon, Adeniums, Champaca, Ylang Ylang). They were all doing well until I tried to move them into full sun, when they got leaf burn immediately. Ylang Ylang was doing great in a shade, but I repotted it from 1 gal into 3 gal and it is drooping leaves now. It has been very hot (over 100F) and dry (humidity is less than 25%). Any suggestions?
A: Hot summer can be pretty challenging time for establishing new plants. These are some guidelines to make your summer gardening more successful and rewarding.
1. You can order plants at any time, but keep your eye on your local weather forecast and try to chose cooler periods to schedule your plant shipments. Here at TopTropcals we monitor weather at destinations, and we can also delay shipment per your request until more favorable conditions.
2. During hot Summer months, many plants are still OK to ship, and to be planted, many species are heat tolerant. It's usually safe to ship most succulents, including Desert roses and Euphorbias. Some fruit trees are pretty easy too, like Loquats, Mango, Eugenias. Many flowering trees can take heat: Acacias, Clusias, Jatropha, Sausage Tree, Plumerias and many others. Check our full list of plants suitable for hot and dry conditions. Most jasmines, including Jasmine Sambac and Trachelospermum make also a safe choice for hot weather planting.
3. Use shade cloth or simply white sheets to protect young plants and new plantings from hot sun.
4. When establishing mail ordered plants during hot weather, keep them in shade for longer period of time than average recommended 1-2 weeks. Give them a chance to establish really well. In areas with low air humidity, try to create a simple mist system. It can be purchased in your local Home Depot for only $20 and set up takes only 10 minutes! It makes a big difference and can help you save many plants from hot weather stress.
5. Although it may seem that during hot weather plants need more water due to high evaporation, be careful with watering, and check soil with your finger before watering - don't water if it is still wet. Combination of "hot and wet" can be as harmful for the root system as "cold and wet" during winter. Protect root systems from overheating: covering black pots with white cloth will work. Remember when temperature is above 90F, most of plants slow down their metabolism, which means roots slow down or even stop pumping water and become more vulnerable to overwatering. For the same reason, do not hurry to step up into bigger container if roots haven't filled yet the existing pot.

Seeds germination in summer
Q: What is the best way to germinate seeds in summer? Should I keep trays indoors or put them outside?
A: Summer is the best growing season for plants, and for their propagation. Seed germination process of tropical plants usually benefits from warm, and even hot temperatures, so keeping pots with seeds outside in full or partial sun can be the best way. However some seeds may be more sensitive than others, or require slightly cooler or higher temperature for germination. These are a few tips that may help:
- For seed germination, use only well drained mixes, containing either peat moss or coconut fiber to retain moisture. Some succulents may require adding sand to the germination mix. You may also try our Professional Formula Seed Germination Mix.
- Large tropical seeds, like palms, or seeds of Fabaceae (Bean) family, can be grown in full sun. Their germination will benefit from higher temperatures (up to 90-95F). Make sure to keep soil moist. Cover them well, with 3/4 to 1 inch of soil.
- Fruit seeds (large size) should be germinated either in individual cells or small pots (3-4" diameter).
- Small to medium size seeds can be grown in so-called community pots. Seedlings can be separated after they establish their first roots.
- Tiny seeds should be planted closer to the surface, covered with only 1/4-1/8 inch of soil; some seeds require bright light for germination, so full sun will be a plus. Some small seeds like Ficus for example, prefer to be broadcasted on the surface, uncovered. Put containers with such seeds in bright shade, as you don't want the surface of the soil to dry out.
- Once your seeds sprouted, move them in filtered light - bright to medium shade depending on tenderness of the species. (Gingers prefer shade, while succulent sprouts can stay in brighter light). Regardless of water/sun needs of the species, all young sprouts and first leaves are sensitive to hot sun and may get burned or even killed. Once a baby plant has a few leaves and well-branched root system, you may start moving trays into a brighter light.
- Do not overwater young seedlings, keep soil slightly moist but not soggy.

Our honest advise on Holiday Gift Plants
Q: Any suggestions on gift plants? With Holidays around the corner, I've been thinking of getting a present for my grandma, she lives in FL and is an experienced gardener. I also have a friend that lives in CA, also warm climate, but she doesn't have a green thumb. Any "easy" plants I can try for her?
A:
Live plant is a perfect gift, as we all know. However when
ordering a plant online as a present, for a happy
experience, you should have three things to consider:
1) Gardener's experience. Planting instructions are
included with every order, and usually success is there if
you follow them. But all plants go through shipping stress
(some more, others less) and need time, patience and love
to recover. Also, a plant will need a new home after
shipping: a pot and a good soil mix. It would be wise if
you add potting mix with a gift
order; the plant should be planted in a permanent pot as
soon as possible, but normally can wait a day in a packing
bag until its new owner gets a pot, if it is not ready
yet.
2) How easy the plant is? If buying a plant for a
beginner, chose something easy, as well as showy. Adeniums - Desert Roses, Jasmines, Clerodendrums, Cordylines are always a good
choice. Calatheas, Gingers and
Heliconias are always showy, even when not in bloom.
Spice trees and herbs are
fun, easy to grow and one can enjoy their aroma right away
without waiting on them growing bigger. Miracle Fruit is an awesome
present, it comes with detailed instructions how to grow
the Miracle!
3) How easy the plant ships? Some plants can be
easy in cultivation, but they don't take shipping well.
After being in a dark box for a few days, most plants
usually recover well in experienced hands. When making a
present, you want something showy, not just a stick to
arrive. Besides Adeniums and Jasmines, many fruit trees
usually take shipping without a problem - such as Mango or Sapote trees. You may not
want to start with Avocado, Papaya, Carambola, or Cacao - unless they go to
an experienced grower - these may take some time and skill
to etanblish. Fig trees are super easy in
shipping, but figs may drop leaves in Winter - for this
same reason, you may think twice about deciduous plants
like Sugar Apples, Grapes, Mulberries or Persimmons to be sent as
gifts. On the other hand, if you are sending a deciduous
tree to a gardener who can appreciate the variety, this
may be a good choice - dormant plants take shipping with
less stress!

Fruitful Fruit and SuperFood...
Q: I have a large fruit garden here in Florida with many mango trees, avocadoes, guavas, and other tropical fruit. Last year hurricane Irma and flooding killed a few avocado trees, but mangos and guavas survived OK, but the sad part is, very few flowers this year and almost no fruit setting. I noticed on your website your Superfood and Sunshine-Honey boosters that supposedly help fruiting? But I am afraid it is too late now as your instructions say first application must be in early Spring? I wish I discovered earlier that my trees wouldn't want to fruit this year...
A:
First of all, it is never late to give the food! You may
start applications of SUNSHINE products at any time
of the year. The best results will be achieved once you
treat your plants on regular basis throughout the whole
year cycle of metabolism.
Couple weeks ago we started harvesting our 2 guava trees.
These two are the same variety (Variegated Honeymoon),
planted within 20 ft from each other and growing in the
same conditions. The only difference was, one was treated
with SUNSHINE-Honey and SUNSHINE-SuperFood, and another
one didn't get any treats in order to have a control
plant.
Results are very interesting, see the picture. Both trees
were heavily covered with fruit. However the one with
treatments developed fruit that is much larger, much
sweeter and juicier, and the most interestingly - with
less seeds, almost no seeds!
To answer your question: yes, you can start feeding your
fruit trees right now. It is still a Springtime. Many
mango varieties have late season; even early varieties may
delay their fruiting if flowering triggered by
miscro-elements. Guavas have very long season and most
varieties can have multiple crops throughout Summer-Fall.
Here is a simple and affordable feeding schedule to
help your fruit garden recover from last year hurricane
stress, and establish reliable production:
1) SUNSHINE-E - for boosting
metabolism - once a month
2) SUNSHINE-Honey - for bringing
sugars to the heart of the tree and boosting fruit
sweetness and quality - now and in 2 weeks
3) SUNSHINE-SuperFood - for
overall health, recovering from hurricane and fixing root
damage from flood - now and every 2 weeks throughout warm
season.
4) You may apply regular balanced fertilizer NPK as
usual (we apply once a month, a handful per in-ground
tree)
It's that simple. Just try and watch your trees produce
again!

TROPICAL GARDENING: How to grow Brugmansia (Angel Trumpet) in the ground outside.
Q: I recently moved from New Jersey to Florida and I brought with me my Brugmansia that I used to have as a house plant. Can I plant it in the ground now?
A: Angel Trumpet - Brugmansia - is a very popular container plant
valued for its large, stunning fragrant flowers. Originated from South
America, it will be happy to grow in tropical to subtropical climate outdoors.
These are a few useful tips to get the most out of this beautiful plant:
1) Light. Plant it in full sun - the more sun, the more flowers
you get, although Brugmansias tolerate shade. If the plant was previously
grown in container indoors, to avoid leaf burn, keep it protected with a shade
cloth or simply white sheet for a while and gradually open to adjust to full
sun.
2) Soil and fertilizer. Use fertile soil with lots of organic
matter (add compost to existing soil). It must be very well drained, Angel
Trumpet won't tolerate waterlogged conditions. Plant it on a little "hill"
elevated 3-4" above the surrounding area. Brugmansias are very heavy feeders. Once
the plant is established, fertilize on regular basis with Slow Release Fertilizer - a handful once a
month.
3) Water. Water daily until established. Once the root system is
well developed, the plant is drought tolerant and won't require too much
care. But at the beginning, watch the leaves - the lush foliage droops quickly
if the plant is thirsty.
4) Plan space. Brugmansia is a short tree, but it needs a lot of
room to spread branches with its heavy hanging flowers. Think 12" wide and
maybe almost as much tall.
5) Support. Being widespread plant, Brugmansia can be blown with
strong winds. Stake with strong support until established.
6) Propagation. Brugmansia is one of the few plants that
propagates with semi-woody cuttings; soft green cuttings usually have little
success. Other than that, it is pretty easy!

How to get Clerodendrum to bloom?
Q: My Clerodendrum thomsoniae is not blooming. Actually it is not doing much of anything except putting out weak growth and small leaves. I purchased this plant May 26. 2015. Over the winter it was in a heated sunroom, at night 60 degrees, where it received some direct sun from the skylights. I reduced the water to prevent excessive leggy growth. I don't see how this plant can take full sun or even part sun. Temps here in Raleigh NC are 80-85 degrees and 65-70 at night, at the moment. I figured I would gradually expose it to more direct sun after being in a sunroom but the leaves burn. I had this plant in San Jose many years ago where it did quite well, blooming with no special treatment. So thought I'd give it a try again. Any advice?
A: Clerodendrums are all time favorites, appreciated by both gardeners and house plant collectors, for their showy, fragrant flowers and very easy culture. When growing Bleeding Heart (Clerodendrum thomsoniae), a few things should be taken in consideration:
1) Temperature.Like most clerodendrums, this plant is semi-decidious outside of tropics and goes dormant in winter. It may lose some or all leaves if temperatures drop below 60-65F. It is not too cold sensitive, the plant can even take some light freeze. However when it is not hot and humid, it slows down metabolism. This means, water should be reduced during cooler months.
2) Light. This plant can grow in both sun and shade like most clerodendrums - this is the beauty of this genus. However like with all flowering plants, more sun promotes more bloom. In shade, it will grow beautiful dark green foliage (leaves will be bigger than in the sun) on the account of flowering; in full sun leaves turn lighter color and sometimes may even get unattractive "faded" look, but flowering will be profuse. Also remember that Arizona full sun is different than New York full sun. Here in Florida, Bleeding Heart can take some full sun, but if exposed to sun all day long, leaves often get sun burn.
3) Acclimation. Also called acclimatization - this is a process when a living organism adjusts to environment changes. Acclimation is always the case when growing plants indoors, even in a sun room. When Spring comes, and especially when we start taking outdoors those plants that have spent a few months indoors, light level increases dramatically, and this may cause leaf loss, and leaf burn. It is not necessarily a bad thing, it is just a mechanism of acclimation. Example: imagine yourself after living in a warm tropical climate, moving to a cold country. For a while your body will feel discomfort from "too much cold", while native residents may feel comfortable. We call it "My blood has thinned after living in Florida" - and this is a physiological fact. And vice versa, if you are a Northerner, moving to hot climate may be a challenge; it will take a while until you get used to hot and humid tropical summers. Same thing with plants: during cooler and darker period, their body (leaves and stems) becomes "winter type", with some serious chemical restructuring. Immediate environment change, like bright light and high temperature, causes a shock to those "winter cells", and as a defense mechanism, the plant gets rid of those useless "winter" leaves, replacing them with new "summer" leaves with completely new chemistry and metabolism.
From what you described, you know your plants, and you know what you are doing. You did everything right by reducing watering in winter and gradually moving the plant into brighter light. You still may see some stress, and this is normal. If you patiently keep changing environment slowly, eventually your plant will generate new healthy "summer" growth, it will also improve more vigorous root grown which will help the plant to establish better and to be stronger. You will see larger, thicker leaves, and definitely some flowers.

Q: I want to order a plant that you have only one left in stock; however the weather is extremely hot in my area right now. Do you have any temperature limitations when you ship your plants?
A: We ship
plants year around and do our best to watch weather forecast at destination.
However the forecast may change to worse within a day or two while a plant
is in transit. To ensure your plants have a safe trip during extreme weather,
follow these steps:
- notify us if you want to wait until weather permitting so we hold
your shipment until further notice;
- make sure to track your package and be at home at time of delivery.
The only time when a plant can get temperature damage, from our experience, is
when the box is left on your doorstep while too hot (or too cold) outside.
- you may use your business as shipping address if no one is home
during regular business hours of delivery.
- unpack the box immediately and follow planting instructions. Keep
plant in shade until recovered; never plant directly from a box into the ground;
never plant into hot, full sun: protect a new plant with a shade cloth for a
few days until established, and water as needed.
- use SUNSHINE booster to help plants recover from shipping stress. It really works! For only $4.95 with FREE
shipping!
