How to get shade quickly... and stay away from oaks
Q: I just moved from Tennessee into a new house in Florida and there are no trees on the property, the yard is brutal hot. What can I plant so I have some shade real quick? I like Florida shady oaks, how long will they take to grow?
A: First
of all, do not rush into oak solution. Oaks are beautiful shade trees, however
they have at least 2 problems:
a) Oaks are slow growers and unless you are willing to wait some 20
years... you won't get that desirable shade that quickly.
b) We have hurricanes in Florida... sometimes. A hurricane can damage
any tree, however with oaks it may be the worse case scenario - the branches
of those giant trees are huge, hard and heavy and in unfortunate situation
when you need to remove or trim a broken tree, it may cost you... a few thousand
dollars.
These are solutions that are more economical and practical:
1) Selection. If you have room, get one of these most popular Florida shade trees: Royal Poinciana, Golden Shower, Hong Kong Orchid Tree, Red Kapok, Bottlebrush, and many others. See full list of fast growing shade trees. Or simply get a Mango Tree and have delicious fruit too! Many varieties of Mangos are very large and fast growing.
2) Do it right. Even if you are planting a smaller tree, 1-3 gal
size, it may become a nice shade tree within 2-3 years and start providing
your driveway with desirable shade. The keys for fast growth are -
a) Good soil. Dig as big hole as possible and fill it with good
rich soil containing compost. See planting instructions PDF.
b) Water. Do not rely on sprinklers and rains. Water your tree
daily for the first week, then at least twice a week for another month. After
that, irrigation system will be enough.
c) Fertilizer. Put a few handfuls of fertilizer in a planting hole. Then fertilize once a month during warm
season. Apply micro elements for even better results and faster growth.
3) Ask experts. Contact our office for advice. We will suggest the most suitable shade tree for your yard based on features of your property: location, soil, exposure, etc.

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!

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.

Looking for the rarest plant? This is the one!
Stifftia chrysantha - Pompom, Rabo-de-Cutia
Looking for the rarest plant? This is the one!
Stifftia chrysantha is an exotic, rare flowering small tree with
spectacular flowers, endemic to the vast tropical savanna ecoregion of Brazil
called Cerrado. It grows into a bushy, attractive tree between 8 and 15 ft tall
and starts flowering within 1.5 - 2.5 years from seed. It is a very rewarding
plant that blooms 9 months out of the year, starting in Winter with great
intensity during July-September, with each flower staying on the plant for
several weeks. Seeds ripen from September through November.
The tree belongs to Aster family (Compositae) and has nothing to do
with Powderpuffs which are from Bean (Fabaceae) family. The flower has 30 to 40
green, imbricated scales with short hairs, and actinomorphic corollas are
orange below and darker above. After flowering, the inflorescence blows apart,
which would scatter seeds. The dried center remaining is very attractive, like
a small dried flower, and lasts for many months.
Stifftia can be grown in full sun to partial shade and is relatively
cold tolerant, can take short cold spells.
The plant doesn't like wet feet
and heavy/soggy soils; requires very well drained, acidic soil. We strongly
recommend to use our professional soilless mix. Let soil
slightly dry between waterings. It can be grown in full sun to partial shade and is
relatively cold tolerant, can take short cold spells. If grown in a pot, try
to keep the container shaded because roots don't like to be overheated. The
plant needs monthly applications of slow
release fertilizer as well as extra iron - use micro-nutrients to
keep leaves green and healthy.

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.

6 things NOT to do in Summer planting
Q: What a hot summer we have... everything I plant in the ground seem to be unhappy and doesn't seem to grow. I water a lot but it seems not enough? leaves stay droopy or get burned. Are there any secrets for summer planting?
A: End of Summer is still a good time for planting in the South, because there are a few more warm months until winter and your plants need enough time to establish before cold season. However because of high temperatures, a few things should be avoid to reduce stress on the plant:
1. Do not plant mail-ordered plant directly from a box into the ground. Keep it in a pot for a week or two and gradually move the pot from shade into permanent location in full sun.
2. Do not expose to full time direct sun even if potted plant was adjusted to sun. Cover newly planted tree with a shade cloth or simply a bed sheet for a few days. Use bamboo stakes to support the cloth. Even tough, sun-loving plants may get a leaf burn if not established.
3. Do not put mulch too close to the stem/trunk. Keep it 1-1.5 inches away from the plant for air circulation.
4. Do not keep wet. Combination of extreme heat and wet is not good for roots (as well as cold and wet). If you notice that soil dries too quickly - water more frequently but lightly, without creating soggy hot swamp.
5. Do not overfertilize. A handful of slow-release fertilizer is good at time of planting, however do not try to push your plant to grow and do not apply more chemicals or manure until you see a new growth.
6. Do not get discouraged and give the plant some time to establish. In most cases, a new growth starts with roots which you can't see. Sometimes it takes a few months until you see the upper part of the tree suddenly starts growing rapidly.

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
