Taking care of Guanabana (Soursop) after shipping

Q: Since I have never grown a soursop tree before I need some pro help. My tree was delivered absolutely beautiful, leaves were a pretty green. I potted it and gave it a good drink of water and put it in a shaded area outside. Then the weather here became cool so I brought it in for a few days until the weather warmed, and it lost all the leaves. Is it in shock and will come around eventually? Will I be able to grow this tree indoors during winter?

A: Soursop - Annona muricata trees are very sensitive to temperature drops. This always causes leaf loss. You seem to be doing everything right. Do not water until soil gets slightly dry; keep it in bright shade. The weather should be good now with high temperatures and humidity rising. No fertilizer until the plant shows active new growth. Be patient with your plant, it should recover soon.

Soursop is an ultra-tropical tree and doesn't take any freeze. If you live in cooler climate, keep the plant in a pot (the good news is, Annonas in general have compact nature and are perfect for container culture). Bring the tree indoors during cold period, providing bright light.

Remember that grafted trees start flowering and producing fruit right away, unlike seedlings of Soursop that may take a few years till fruiting.

Growing mango in hot Arizona

By Mike D, Mesa, AZ. Despite to what you may think, mango can be successfully grown in desert Arizona climate. It has good heat and drought tolerance. It's possible providing the following:
1) Winter protection of a young plant when temperature goes around or below freezing. Try to plant trees in locations where they're protected from cold wind. Minimal temperatures vary widely. Areas which are closer to downtown are few degrees warmer, while outskirts can be very cold.
2) Some people are lucky enough to live in areas with good soil. However, most of us will have a so-called hardpan (extremely compacted desert) or caliche (layers of soil cemented together by calcium carbonate). Check with your local county extension office to determine how to deal with such conditions. Gypsum is usually used to loosen compacted soil.
3) When planting, dig a large hole making sure it has good drainage. Plant tree as usual, add mulch around it. It helps to conserve moisture.
4) Best time to plant is late Fall or early Spring, so mango can get established before Summer heat.
5) Plant where tree gets few hours of sun.
5) Water a lot until established. Once established, water when soil is dry.
6) Small plant may need protection from summer heat. Use shade cloth.
7) Mango requires very little nitrogen fertilizer. In hot climate, overdosing nitrogen may result in quick plant decline. Use balanced low nitrogen slow release fertilizer or avoid nitrogen completely. If you use mulch, then decomposing mulch provides enough nitrogen. Foliar spray of micronutrient solution is recommended during active growing period. Read more...

Growing Vanilla Orchid

Q: I want to buy Vanilla orchid and I wonder if I can grow it in my bathroom by the skylight.

A: Growing Vanilla orchid is no different than other orchids. It is very simple. All that the plant needs is a good light, good air humidity, and good porous support.

Light. Grow Vanilla orchid in a very bright light, but protected from direct hot sun.

Air humidity.The higher the air humidity, the better your plant will grow. Many people grow orchids in a bathroom where these plants can enjoy occasional "humidity treats" after showers.

Growing media. Vanilla orchid cuttings are rooted very often in a regular potting mix with high content of pine bark and/or Perlite, Coconut Husk Chips. Once the little plant is well-rooted and starts developing, it will need a special porous surface to climb on and to attach to with developing aerial roots. A log covered with porous bark is used often. Another option is a piece of wood wrapped with a burlap fabric. In the Nature, this plant climbs up high onto trees and attaches to the bark with aerial roots - at this point, it doesn't need those terrestrial roots any more which may even die off. Climbing a porous support is absolutely necessary for your vanilla for setting buds, flowering and producing vanilla beans. If you are lucky to live in frost-free climate, plant you vanilla by a tree that will provide a shady canopy and a great natural climbing surface (bark). You may see the flowers as soon as within 1-2 seasons!

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.
