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!

Varieties of Guava
Q: We were just in Australia where guava juice was available in the markets. Pretty sure I can grow different varieties of Guava's here, as I have 3 already, but wondering if it would be psidium guajava or littorale as the best bet for making the pink juice we enjoyed. Thanks so much, your plants are so healthy when they arrive!
A: Both species are used for commercial juice making. We grow lots of Psidium littorale - Cattley Guava, Strawberry Guava - and we make delicious juice. Psidium guajava - Tropical Guava, Guajava - is less juicy, fruit is somewhat dry, but it still has a great flavor; you may need to add water to blended pulp. And sugar - add it to both kinds of fruit!

SUNSHINE in a bottle - your help during winter
Q: I have been using your new plant hormone SUNSHINE for plants after shipping, and I must admit it does make a big difference! They recover right away. I order plants online very often, and usually it takes up to a week or more until they start showing new growth. After SUNSHINE treatments, they look fresh within a day or two. My question would be, for improving cold tolerance, what do you recommend? I live in Florida and it is still warm here, should I start spraying my garden now or should I wait until cold spells?
A:
SUNSHINE
is very effective plant stimulant that helps tropical
plants survive different kinds of stress, including
cold, heat, drought, low light, etc. At TopTropicals
gardens and nursery, we have been using this hormone for
many years to protect our plants from unfavorable
conditions, and it saved us many rare tender species,
and lots of money!
The sooner in Fall you start treatments, the better.
Don't wait until cold spell. SUNSHINE works slowly and
in very low doses. The mechanism is actually about
boosting, building up the plant's own immune system. Low
doses once a week, even every other week will work just
fine, so you will need very little of the product. For
less than $5 you can help expensive rare plants to go
through winter painlessly. Recommended application is
only 2.5 ml/1 gal of water, to spray every 1-2 weeks
throughout winter period.
Start spraying your plants with SUNSHINE now, to help
them survive short winter days, build up insect
resistance (especially for plants indoors), and what is
most important, to remain strong through lower
temperatures. These are our suggestions:
- SUNSHINE-T
- thermo-protection booster. It is specially
formulated for winter protection of tropical plants. To
improve cold hardiness even more, spray 1-2 days prior
to cold with 5 ml/1 gal solution and after that,
continue applications with 2.5 ml/1 gal solution every
10-15 days throughout winter period.
- For large plant collections, and in-ground gardens in
subtropical areas, take advantage of very cost effective
bulk items 50
ml and 100
ml bottles of SUNSHINE.
- Don't forget that SUNSHINE is only a stimulant, and
not a plant food. While regular fertilizer should be
avoided during winter months, it is always beneficial to
apply microelements through foliar spray. During cooler
period, chances of chlorosis increase, because at low
temperatures iron is difficult so absorb by roots
especially in moist soil, hence iron deficiency! Our new
Iron supplement SUNSHINE-Super-Iron
microelement booster will help to avoid yellowing leaves
and to maintain your plants strong and healthy during
slow growth period. Ultra-potent, highly absorbable iron
mix, with chelated Iron with DTPA (instead of usual
EDTA) that is better soluble in hard water and more
effective for chlorosis. This mix contains both EDTA +
DTPA chelated iron in higher concentration than regular
micro-elements mixes.

Planting instructions for bare-rooted succulent plants
Q: I would like to order a few Adeniums from your selection. You website says "shipped barerooted". What do I need to know about potting these plants before I order?
A: Adeniums do not require much soil; large 4-5"wide caudex plant can be grown in 1 gal pot. After unpacking the plants, position it in a pot, size of root system. Use only well-drained soil with high content of perlite and/or sand. Cactus mix can be used too, although we recommend using our special TopTropicals professional soilless potting mix. Water once and keep in warm (75-80F) place in filtered light. Do not water again until soil dries on surface. Once the plant is established and starts growing new leaves (may take a few weeks), gradually move it into brighter light. Then you can start fertilizing it. You may place shells and lime rocks on top of adenium planting, as these plants benefit from slightly alkaline soils.

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.
