7 secrets of a Happy Avocado Tree
Q: I purchased an avocado tree from local garden centers three times but every time it dies on me. My neighbor has a nice tree in his yard and it grows beautifuly. I just purchased one online from you and I need to know what I was doing wrong? Are there any secrets how to make an Avocado tree happy? I have a big garden and several mango trees, but no luck with Avocado...
A: Avocado tree is famous for being such a pain to establish. But once it starts growing, it's growing! We will share a few simple tricks how to make it right.
1. Plant high and provide good drainage. Wet feet is number one
reason for failing an avocado tree. It doesn't like wet soil and won't
tolerate soggy conditions. Plant it in the highest spot of your yard and slightly on
a "hill" (3-4" higher than the surrounding ground).
DO NOT plant Avocado tree in low spots or wet spots of your yard. Save
those spots for Cannas or Black Sapote or even a Mango if you want a fruit tree there.
2. Use quality soil. Use only well-drained soil with high content of
organic matter. You may add compost to existing sandy soil, or add some professional potting mix that contains pine bark and perlite. Remove
rocks from the hole if you see any while digging. Dig a big hole and fill it
with a good soil; compact the soil in the hole very well before setting the
root ball. Reminder: plant the tree high!
3. Water regularly. After planting an Avocado tree in a nice high
spot with a good drainage, start watering it... daily! Avocado likes water,
although it doesn't like wet feet! Once you figure out this combination, you've
got the recipe of success. Water by hand daily for the first week after
planting, then twice a week for couple weeks, then once you notice new growth -
you may rely on sprinklers, but keep watching the tree and don't let the soil
over-dry. It must be slightly moist, but not soggy.
4. Fertilize. For such finicky tree, we suggest mild formulas of
fertilizers. Dry fertilizers may burn roots, especially of a young tree. Even
smart-release granulated fertilizers should be used very carefully. The best
way to feed your young avocado tree - get a complete set of Sunshine Boosters Pro system. It has all necessary elements for all
stages of plant development and never burns the roots. Sunshine Boosters Pro can
be used with every watering - no need to guess how much and when. Besides,
it is a natural fertilizer based on amino acids - exactly what you want to use
on your fruit trees and other edibles!
5. Boost immune system of the tree. Apply Sunshine Epi plant hormone every 2 weeks as a foliar spray to boost
immune system and metabolism of the tree and protect it from diseases. Epi makes
plants (especially young plants) grow twice faster! It also enhances effect
of fertilizers by increasing plant metabolism.
6. Do not prune until you see significant growth. The tree is small
and can use as many leaves and branches as possible for photosynthesis and
healthy metabolism. We suggest to avoid pruning for at least the first year. On
the second year your tree most likely will be covered with flowers (assuming
you followed fertilizer program). Let it go through the blooming stage and
setting fruit; prune in Fall after fruiting is over.
7. Keep number of fruit to minimum for the first crop. Don't let the
small tree exhaust itself. Keep just 2-3 fruit to develop. The next year, no
need to control fruit quantity, the tree will develop as many as it can
support.
P.S. If you got the tree from a mail-order, remember to establish it
in a pot before planting in the ground; move gradually from shade to sun.
Follow planting instructions.

Growing desert roses
Q: I purchased a Desert Rose and planted it in Adenium mix. I keep it in full sun with once a week watering assuming this is a desert plant that likes lots of sun. Some leaves turned yellow and now I am not sure should I move it into shade or need to water more? Or maybe fertilize with something?
A: Desert Rose - Adenium, unlike cacti and other succulents, prefers filtered light. It can grow in full sun but leaves look healthier in light shade. Watering must be very moderate, however don't let soil harden like a rock: water again right after the soil gets dry. We suggest to use special Adenium Mix. Cactus mix may work well, as well as regular potting mix, in which case it is recommended to add a bit of limestone (we simply put sea shells on top of the pot - it looks very pretty!) - because adeniums prefer slightly alkaline soil (while most of tropical plants like acidic soils). If leaves turn yellow, this may be a sign of underwatering. Use water soluable fertilizer with high phosphate as foliage spray, and only on healthy plants, according to label dosage. It helps both caudex growth and flowering. Make sure to avoid fertilizer contact with a caudex.

Three interesting varieties of Avocado
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, we are 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 the backyard. Even a single tree produces enough fruit for a home gardener.
It is also important to know that while there are "more cold hardy" avocados (hardy to as low as 15F), it refers to a full grown established tree. Young trees still need protection from the cold until they are bigger and more established. One can not expect a small tree planted in June to survive the first winter with a hard freeze. It'll take a few years until the tree is strong enough.
These a few rare varieties that may be of your interest.
Poncho Avocado
Very cold hardy variety. Produces medium to large green fruit. It
survived temperatures around 10F near San Antonio, Texas (Zone 8b). Mature trees
can take temperatures down to 15F for short period of time without significant
damage.
Anise Avocado
This avocado has strongly scented leaves that smell like Anise. Very
rare variety. Fruit is of excellent quality, creamy and buttery.
Catalina Avocado
Catalina is a very nice mid-season pear-shaped fruit that is especially
rich and creamy. It is an extremely popular variety in South Florida in the
Cuban Community. The Story of this variety says...
...Catalina is an amazing avocado floated across from Cuba, 60 years
ago just before Fidel Castro took over the Island Nation. Wise Cubans jumped
into the ocean to escape the Castro regime and tossed in some favorite scions
for us to enjoy here in the States. We owe a great debt to poor old Don Miguel
Cruz de la Santa Maria Espinoza Sanchez Alvarez Jr. who sadly was lost at
sea. His amazing scion wood, wrapped in cellophane and aluminum foil floated
over, washing ashore on Miami Beach. His shiny little package was miraculously
picked up on the shoreline and immediately grafted and cared for by keen-eyed
avocado lovers in Miami...
So be sure to think about this story every time you eat a Catalina!
These three Avocados will provide you with fruit ripening during the whole warm season. See more information on avocado varieties and the most cold hardy cultivars.

Chosing a good avocado tree
Q: I'm in coastal Broward County. I'm putting together an order on your web site, and one thing that I would like is an avocado tree. I'd like to have something as close to true "Hass" as possible. Which cultivar does well here in SE Florida, and is most like Hass in texture, creaminess, and flavor? I'm not a big fan of the yellow watery Florida avocados.
A: Mexican type of Avocado have dark skin and buttery texture,
while Florida green fruit types (West Indian type, with smooth skin), have lots
of delicious melting pulp, so it is a matter of preference.
In coastal Broward county you can grow a wide range of varieties since
your climate is very mild, so you don't have select cold-hardy varieties like
Winter Mexican, Brazos Belle or Joey, etc. Yet there are many interesting varieties that rare and much
more exclusive than Hass, with the same, or even better, quality buttery
fruit.
One of the most popular varieties - Brogdon, with red-purple colored pear-shaped fruit, very thin skin, and yellow buttery flesh. It is also very cold hardy.
Very interesting exotic avocado is Kampong - Sushi Avocado - see photo above. The flavor of this fruit very nice, oily, creamy, nutty, reminds of almonds. At the same time, it has solid consistency and if you cut a square it remains a shape of the square. It is the best Sushi Avocado! It tastes great as an appetizer when cut in squares with some shrimp cocktail sauce.
Three collectible varieties:
Anise - leaves that smell like Anise, very rare, the fruit is of excellent
quality, creamy and buttery.
Bacon - a large Mexican variety with dark-skinned medium-sized fruits, and
a rich creamy flavor. It has exceptional fruit that ripen in late fall and
into spring, they are easy to peel and have a light, subtle flavor. Another
outstanding feature of the Bacon avocado tree is its angelic sweeping branches
which helps keep the tree shorter and easier to pick its fruit.
Nishikawa is a very hot seller! Oval fruit somewhat resembles Hass, but
larger, and has very high oil content.

Trimming and treating Adeniums in winter
Q: My desert rose below dropped leaves after I replanted it in a bigger pot. I noticed that one of the branches that had been pruned is black at the tip. Please let me know if the section of the branch that turned black needs to be cut. I also wasn't sure how often to water it since the leaves have all dropped. None of the other dessert roses have dropped their leaves but they are all younger plants. Any advice would be much appreciated.
A: Your plant looks healthy and vigorous overall. Dropping leaves
after repotting, or shipping, especially at this time of the year, is normal
in Adeniums. They are deciduous and stay leafless from Fall to Spring.
Some individual specimens can go into dormancy sooner than others - all depends
on conditions: temperature, light, exposure, etc. and individual plant's
"clock".
The black spot on the cut branch may be a sign of a fungus as a result of
excess water.
You may carefully clean/rub it with a paper tower dipped in Hydrogen
Peroxide (pharmacy grade). Then rinse with fresh water.
Keep the plant warm and in a dry spot. Once leaves are dropped, it doesn't
need much water. Once a week watering is enough.

What you need for successful growing Adeniums
1) Adenium plants - from TopTropicals Endless selection of
Adeniums. We have double flower, red, purple, yellow
and even black flowers!
2) A small pot with excellent drainage is a must.
Position the plant in a pot, size of root system.
3) Adenium soil mix. TopTropicals Adenium Soilless Mix.
Use only well-drained soil.
4) Lots of light. Adeniums need lots of light for
heavy flowering. However from our own experience, in super
hot climates, they look healthier in filtered bright
light. After initial planting, once the plant is
established and starts growing new leaves (may take a few
weeks), gradually move it into brighter light.
5) Little water. Adeniums like a neutral to hard
water. Acidic water tends to sour the soil too fast and
may cause root rot. Water plants preferably in the early
morning, and allow them to drink up throughout the day.
Watering can be done daily to every few days. Do not water
again until soil dries on surface. Never allow your plants
to sit in a saucer of water, but don't let them to dry out
too often - this causes adeniums to go into early
dormancy. Adeniums do not like both over-watering or
drying-out.
6) Fertilizer. To make your plant develop a large
swollen base/trunk, you'll need a good quality fertilizer.
Use slow-release granulated fertilizer
for overall plant health, and liquid water soluble
fertilizer for swelling up trunks that is also used to
increase flowering. It shouldn't be too high in nitrogen,
the middle number should be the highest (similar to
10-50-10). Never apply fertilizer directly on roots and do
not liquid feed when a plant is thirsty: always water
first slightly to avoid root burn and leaf drop. Do not
wet leaves.
7) SuperFood micro-elements. Besides
macro-nutrients provided by fertilizer, Adenium needs
micro-elements for balanced development of root system and
especially caudex: Sunshine-SuperFood.
8) SUNSHINE-BC. Spray leaves with SUNSHINE-BC once a month to
encourage young growth, profuse flowering and large
caudex.
9) Growing caudex. There is a secret how to create
a large swollen caudex: raise the plant a bit every time
you re-pot it, so that the upper part of roots will be a
little exposed. The plant will form more roots that will
go down.

Q&A from Mr Booster
Establishing Avocado Tree
Q: I received my avocado Wurtz tree yesterday. Per instructions I have put the tree in a pot first. However I am having difficulty deciding what to trim off. Yesterday I removed obvious damaged leaves. However as you can see, the leaves are lighter in some areas and contain yellow and red in some spots. What would you advise? Given this is a critical state as I do not want to shock the tree after the trip, I would like to do everything possible to protect it and ensure viability.
A: Your Avocado tree looks great and healthy overall. You've done excellent job planting it. Wurtz is a good, vigorous variety, while the tree is somewhat dwarf,
great for containers.
You are right, it is the best for the tree to leave it alone and do not
trim or remove leaves any more, until it starts showing new growth. Then it will
be obvious what needs to be trimmed. Reddish/orange color of young leaves is
normal. If any spots or dots - no need to remove those leaves yet. Wait
until the plant grows more leaves. It needs them for photosynthesis, in order to
become stronger.
Keep the tree in bright shade and gradually move from filtered sun to
full sun. Water daily. Within a week or two after planting, you can start
applying mild fertilizer and micro-elements. We recommend at this growth stage:
SUNSHINE C-Cibus - Crop Nutrition Booster
SUNSHINE SuperFood - Micro-element Plant Booster
SUNSHINE C-Cibus - Crop Nutrition Booster from Garden Series, or Combo Total Feed Collection - all nutrients in just one bottle, for fruit trees and edibles.

Healthy Plants - Q&A from Mr Booster: Feeding Avocado Tree
Q:We bought one of your avocado grafts and it's doing great, lots of buds for fruit. It's still in a pot and fertilizing with the Sunshine Boosters. Should we continue with this product? We'll plant it in the ground in March. Thought you'd enjoy pictures of our wonderful tree. No freezing temperatures in Riverview, but when it got down into the 30s, the plant came in. One good thing about growing in the pot. I'll be buying some more Sunshine Boosters. This stuff is working great on all our plants.
A: Congratulations with a good job on growing avocado over
winter. Avocado trees are not easy, we are happy to hear that your plant is ready
for production, this is amazing! We've noticed that Sunshine Boosters perform
miracles. Here are some suggestions for you:
1) Continue fertilizing with Sunshine Boosters according to the feeding chart
2) When ready to plant, dig a large hole and fill it with good soil full of
organic matter (compost mixed with existing sandy soil will be good). Make
sure to plant the tree on 3-4" high elevation, like on a little hill. Avocados
need perfect drainage and can't tolerate wet feet. See more info on planting and planting instructions (pdf).
3) Water daily with a hose, do not rely on sprinklers. Avocados like water
(considering perfect drainage)
4) Continue applications of Sunshine Boosters at least until the tree is established and starts
growing new branches with lots of leaves. After that, you can switch to
slow-release fertilizers once a month if it makes it easier, but if you can, continue
Sunshine Boosters at least on weekly basis - they really boost plant growth!

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.

Shipping Tropical Plants Worldwide
Q: We are very interested in introducing frost-hardy avocado varieties into Switzerland. We would really, really like to have our own avocados in our garden. And we believe that the plants have a large sales market here. Do you see a way to send some plants to Switzerland? Which varieties would you recommend, which are the cold-hardiest?
A: Yes, we do ship plants all over the world, including Europe. For basic information on international shipping, please refer to these guidelines. Shipping plants internationally is a bit complex procedure, however we have over 17 years experience with that and you came to the right place. For a quote on shipping cost and to make sure you get all the necessary paperwork, contact our international department direct number 239-771-8082 or email us .
Regarding your questions about Avocado varieties:
First, please take a look at Cold hardy Avocado varieties guide pdf file. The most cold hardy
varieties like Brazos Belle, Fantastic, Joey, Lila, Poncho, Winter Mexican - can
take short period of light freeze as long as they well established. This means,
for the first year or two you need to protect them from freeze. Keep in mind
that if you have hard freeze every night for several weeks, then even
cold-hardy Avocados must be grown with cold protection. It is possible to do by
creating a greenhouse/conservatory around plants in the ground, see example from one of our customers in Virginia. Even better - grow them
in large pots. This way plants will be easier to handle and move around as
needed. See the photo above of avocado production in pots.
