What pot is good for Medinilla?

Q: I just acquired a Medinilla plant. I have a cylindrical tall clay pot that I would like to repot this beauty into. Would like to know if a deep pot is good for this type of tropical plants even if the medium is lightweight with bark and perlite allowing adequate drainage. Would appreciate your advice.

A: Medinillas are very close to epiphytes, meaning they like high air humidity and very good soil drainage characteristics. Clay pots usually provide good air circulation, as long as they are not glazed. If you add a lot of soil conditioner into your mix, like orchid mix and perlite, the tall pot will provide a good drainage. Tall pot is also great for displaying the beautiful pendulous blooms!

Plastic pots work well too, as long as you provide a well-drained soil for the plant. If a nursery plastic pot is not pretty enough, you may place it in a fancy planter; however, make sure never let the pot sit in water, Medinillas do not like wet feet.

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!

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.
