When to fertilize and prune tropical fruit trees?

Q: Can tropical fruit trees (Soursop, Mango, Star fruit, etc) be given plant food any time of year? Also can they be trimmed this time of year/summer?

A: True tropical plants (including fruit trees) need plant food most of the year in real Tropics, where temperatures have very little fluctuations, and active growth season is close to 12 months a year. In subtropical areas when temperatures in winter drop below 65F, plant metabolism slows down, so it is recommended to fertilize only during the warmest period (March through November). So yes, Summer is the perfect time for fertilizing your trees; their metabolism is at the highest point and they can use more food!

Trim your fruit trees right after harvesting. Obviously, you don't want to prune branches before or during flowering or fruiting. The specific time of the year for pruning depends on the plant - every tree has its own flowering/fruiting season. However, avoid pruning right before winter: young shoots promoted by pruning are tender and can be cold damaged.

Perfect small tree for a pool area

Q: I need a tree for a space that is close to a pool and I don't want a tree that is shedding leaves all year long. I don’t want it too big either. The canary tree caught my attention but I need to know if it is a tree that is dropping leaves all year. If it does then can you recommend another tree? I live in Fort Lauderdale.

A: Canary tree is a good choice. It is free-flowering pretty little tree. It is evergreen and doesn't shed leaves too much especially in your area with mild winter. However, keep in mind that every plant sheds leaves. Even evergreen trees replace old leaves with new ones. Some trees more than others. Flowers also have a seasonal drop. You may check the full list of compact flowering trees suitable for small spaces.

Another great choice is a Dwarf Tree Jasmine, Radermachera - also a free-flowering tree with rose-fragrant flowers and large, architectural leaves that hardly ever drop. It has very dense yet compact columnar shape, and is one of the greatest trees for smaller landscapes.

How to grow Soursop in a pot

Q: Is it possible to grow soursop in a large pot for life?

A: Soursop, or Guanabana - Annona muricata - is actually one of those tropicals fruit trees that can be easily cultivated in a container. Most plants of genus Annona have compact nature, and these fruit trees usually start production at a young age, as early as 3 years from seed. Annona muricata seedlings take a little longer to fruit, this is why we offer grafted trees, which can start producing right away.
We have a very interesting article about growing Soursop in an apartment. The article was written by an indoor gardener who lives in a very small apartment in Moscow, Russia. He grew this tree from seed and after years of cultivation fun, he finally got several large delicious fruit! It is an amazing story. We have it published in our Tropical Treasures magazine, download the whole issue #7, get a hard copy, or you may download PDF file of the single article.

A Cup of Tea Plant

By Onika Amell, tropical plant specialist

A: I live in Ave Maria, Florida. I want to try my hand at growing my own tea. Which plant do I need?

A: Most people do not realize they are actually enjoying camellias when they sip their cup of tea. True tea comes from the Camellia sinensis plant, an evergreen shrub or small tree.
In the fall and winter, the plant will produce small white flowers with a lovely fragrance. The foliage is shiny and dark green with a very nice informal and open look. Camellia sinensis (or tea plant, as it is commonly known) prefers a temperature between 65 and 86 degrees, which makes Florida an ideal area to grow them. However, if you live in colder zones, you can certainly succeed growing your own tea plants using a greenhouse. Alternatively, you can use containers which can be brought inside when temperatures start falling. Tea plants will usually survive a very slight freeze, though the leaves may be damaged or killed. It will not tolerate a hard freeze. They prefer full sun or light shade in the garden.
Tea plants will become small trees or large bushes if not pruned. Hardcore tea growers trim back the shoots repeatedly to a height of around 4 feet to encourage new growth and to contain the size.
Make sure to pick an area of your landscape where it does not flood or remain wet during our rainy season. Camellia sinensis does not like wet feet at all. They prefer well-drained, sandy and slightly acidic soil. If grown in a container, add some sphagnum moss to the potting mix. They will benefit from frequent applications of small amounts of fertilizer.
You will need some patience, too. Your plant should be around 3 years old before you start harvesting leaves.

Erythrina vespertillio - Bat-Wing Coral Tree

by Mark Hooten, the Garden Doc

...Even in its native homeland, the species remains uncommon, and most Australians have never even heard of it!.. Now, the Bat-Wing Coral tree is likely my all-time favorite small growing flowering tree in existence. There are not enough superlative adjectives I know to properly and adequately describe it. Imagine closely packed long-lobed blue-green bat wings in groups of three on long thin stems which actually rather flutter in a breeze...

Planting and mulching during hot summer

Q: I would like to buy some trees and vines for my garden but I am not sure if it is a good time for planting. It's hot now in Florida. Should I wait till it cools off? If I plant now, can I rely on sprinklers?

A: Summer is always a good time for establishing plants because this is the time of the most vigorous growth. For the first 2-4 weeks, plants should be watered daily with a garden hose as you can not rely on sprinkler system yet. Mulch around plants generously - this will help:
- Maintain moisture
- Maintain soil temperature - protect roots from heat
- Reduce weeds and grasses
- Provide nutrients to the soil, and
- Reduce wind erosion from uncovered soils

Variegated Shell Ginger - Alpinia zerumbet

By Onika Amell, tropical plant specialist

Q: I live in Deltona, Florida and hoping to find spreading ginger with interesting foliage to grow in a partially shaded area in my garden under a group of trees. Any suggestions?

A: Variegated ginger Alpinia zerumbet variegata is a clumping ginger valued for its beautiful variegated foliage. The dark, green leaves have striking yellow stripes. This ginger is sought-after, not only for the stunning foliage but also for its beautiful flowers. The flowers are different from other members of the ginger family and appear in drooping racemes from the ends of leafy stems rather than directly from the rhizomes. This ginger is also commonly known as Shell Ginger because the flowers resemble seashells! They are pink-tinged, fragrant and appear in summer. This evergreen perennial grows in upright clumps 3-5 feet tall. You may prune the plant to control size.
It does not tolerate drought or a hard freeze but can take a few hours or light frost (goes dormant in such case). In colder areas, rhizomes should be dug up and stored in a cool room during winter.
This ginger will love a shaded corner in your garden. Plant it in organically rich, well-drained soil in full sun to part shade. Keep the soil moist but not soggy, and spread a thick layer of organic mulch around the plant for moisture retention. There are no serious insect or disease problems to worry about!
This ginger can be also be grown as a house plant as long as it has bright light and humid conditions. It will grow to around 3-4 feet tall as a houseplant.

How soon will Guava tree fruit?

Q: Can you tell me how your Guava trees are propagated? Grown from seed vs. air grafted, etc.? I'm interested especially in the Barbie variety. In particular, I'd like to know how long it takes them to bear fruit - I live in Southern California zone 10b, with good sunlight.

A: Guavas can be propagated by seed, air layers, or grafting. Propagation method depends on the species.
Cattley guavas - Psidium littorale - are usually grown from seeds and start flowering and producing as early as in 2-3 years from seed. Tropical guavas, Psidium guajava - especially named varieties, are propagated usually by air layers, and the rarest varieties like Variegated Honey Moon are often grafted, although they will come true from seed (it's just takes them longer to fruit). Both air-layered and grafted plants start producing right away, usually on the same year of planting or next year, depending on growing conditions.
Barbie Pink is a superior variety, very popular among fruit lovers. It produces large aromatic fruit with a bright pink pulp and very few seeds. This variety is air-layered; in our nursery, these plants start flowering and setting fruit in 3 gal containers.
Plant this tree in full sun and provide regular watering, guavas don't like to dry out. Use fertile soil, with at least 50% of compost, and add some soil conditioning components for better drainage: bark, sand, perlite, etc. Mulch well, just make sure to keep mulch 2-3" away from the trunk. Follow our detailed planting instructions that come with every plant, and you are good to go!

Growing Jackfruit in a pot

Q: I have a young jackfruit tree, and I wanted to know, is a 25 pot enough for an adult tree?

A: 25 to 50 gal should be eventually a good size pot for growing a Jackfruit tree. Keep in mind the following:

1. Start with a smaller container, only slightly bigger than the root system. Do not plant directly into a large container, this may create a risk for root rot.
2. Step up the tree in a bigger container every year as it grows bigger. With every repotting, trim both branches and roots to compact the plant and to encourage branching out.
3. Jackfruit trees should be kept pruned under 6-7 ft in pots and 10-12 ft in the ground. This makes healthy fruit production more efficient and keeps fruit at the base of the tree.

   

Repotting Artocarpus with a taproot in ground

Q: The Chempedak I bought from you almost 3 years ago which I had repotted twice has a thick taproot growing in the ground, which I noticed this past winter. I was going to repot into the largest size pot almost half of a 55-g rain barrel. Can I try to dig/save as much of the taproot before repotting, will it die if I had to shorten/cut what I can't dig out completely? I hate to put it in the ground for fear it may not make it when we have severe cold/long hours of frost. I live in west Cocoa, Central Florida, 9b.

A: Yes, you can repot the tree and keep it in reasonable size container after trimming the roots. Most of the tropical trees (fruit trees not an exception) can be grown in containers even if in Nature they grow into vigorous large trees. The key is, trim the roots every time you transplant it. The process is similar to trimming branches and both don't hurt the plant as long as done right and moderately. You should trim the overgrown and spreading limbs at the same time. You may trim as much as 10% off root system at the time of repotting. This will cause the root system to branch out and become fuller, similar to branches, which is a good thing. If a tree grows a taproot like in your case, it is not necessary to try "saving" and digging out the whole root that may go down for a few feet. You may cut it off without major damage to the tree since the rest of its root system will continue to support the plant metabolism. Just keep in mind that the plant will be stressed for a while - so put it in bright shade and water regularly until signs of stress go away (wilted or dropping leaves may occur). This particular type of tree - Artocarpus - is pretty strong and vigorous so the stress should be minimal.
