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.

Triple Sec Mango

TopTropicals.com

By Onika Amell, tropical plant specialist

Q: I live in Mesa, Arizona. I am considering purchasing two of you Triple Sec Mango trees. Can you please give me some information on this variety and how to grow it successfully here in hot and arid Arizona, if at all?

A: Triple Sec Mango is a new name for the superior variety Seacrest. The aroma of this fruit resembles Triple Sec - an orange liqueur. It's a juicy, mid-season variety that has good disease resistance.
Mango has pretty good heat and drought tolerance. It loves sun, but there are a lot of factors to consider when growing Mango in your area.
Check your soil. Soil quality is always first and foremost: when you live in an area of Arizona with hardpan (extremely compacted desert soil) or caliche (layers of soil cemented by calcium carbonate) you will have to learn how to deal with such soil types. Amend the soil as needed.
The best time to plant is spring or fall to give your Mango a chance to get established before the really intense Summer heat starts. Alternatively, protect the tree with a shade cloth. Tender, new growth will not stand a chance unprotected, especially newly planted and/or young trees.
Mangoes are tropical and sensitive to frost and freeze damage. Young trees especially will also need winter protection when temperatures go near or below freezing. Always plant trees in a location where they will be protected from cold wind. Consider staking your newly planted Mango trees for the first year. It's never a bad idea to even stake during periods of high winds.
Make sure your planting site has very good drainage. Always use a good quality mulch around your tree as it helps to trap moisture, keeping the ground and the roots beneath it cool. Keep mulch a couple of inches from the trunk of the tree. Avoid a location that gets full day sun. Morning sun, afternoon shade is ideal. Give regular watering until the tree is established. Once established, water only when the soil feels dry.
Fertilizer with a Mango-Food. A foliar spray of micronutrient solution is always recommended during the active growing period. Use plant stimulants and microelements to improve cold hardiness and vigor.

How to grow Angel Trumpet in Florida

Q: I purchased an Angel trumpet in March, 2018. It wasn't looking very good so I asked what to do about it. Your reply was to fertilize and keep it watered. I did & it started to improve. I went on vacation & it reverted, dropping leaves... How do I keep it happy?

A: With growing Angel Trumpets in Florida, there are a few things that may go wrong, although in general Brugmansia is a vigorous rapid grower. Once the plant is established, it is very easy to grow. Looks like your plant had some troubles at the start and is still struggling. Dropping leaves could be a sign of a root problem.

These are the main important points for Brugmansia growing:
1. Must be planted in a high spot, using very well-drained soil. Brugmansias do not like soggy conditions (happens with Florida summer). They like water, but only as long as drainage is good.
2. Full sun is a must for a healthy plant.
3. Brugmansias are heavy feeders. Fertilize at least once a month once the plant is established:
Pink N Good Daily Plant Food - Flower Booster
Angel Trumpet Delight - Smart-Release Booster
4. They are susceptible to bugs... check underneath the leaves and if any pests, spray with solution of any vegetable oil, water, and some dish soap.

The bottom line is, do not overwater but don't let it dry out. It's rainy season now, maybe too much rain affecting the plant.

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!

Trimming Mussaenda bush

Q: My wife and I bought a Dona Evangelina from you this year. It thriving and has grown to 6-8 ft. It has become top-heavy and in wind, it falls over. Main stems have split twice but still continues to grow. I usually prune Dona Luz back to 3-4 ft and am wondering how much you would advise me to lop off your plant. Any advise will be appreciated.

A: Mussaendas, indeed, have very fragile stems that break often, especially in Florida wind storms. The good news is, these plants grow vigorously once established.
You did a good job trying to tie together the split stems and in fact, cracks do grow back together as long as the dressing is tight. Try to use green tape or even electric tape to tighten the broken spot.
However, do such repairs only if it is critical for a plant. When possible, simply cut off the broken branch and give the plant a chance to grow a new stronger branch. You may trim the bush pretty short. Mussaendas respond well to pruning which promotes more side growth and makes the plant bushier.
Keep in mind that during cold weather, Mussaenda may drop all leaves and go into dormancy until spring.

Fragrant Gold Leaf Orchid Vine

By Onika Amell, tropical plant specialist

Q: I am absolutely thrilled to see you have this vine. I've tried for years to get this plant! It is so, so rare. It just seemed impossible to find in this country. How do I make it thrive? I am ordering two.

A: We are happy to confirm that indeed we do have this rare vine!
Bauhinia aureifolia - Gold Leaf Orchid Vine - was discovered in Thailand in 1983. It is endemic to Pattani, Narathiwat, and Yala in Southern Thailand. Danish botanist Kai Larsen named this plant and hailed it as one of the rarest plant species of the world when it was discovered in the eighties.
The Thai people call this vine Bai Mai Si Thong. It is a beautiful climber with large, bi-loped leaves (7 inches or more!) and good branching.
Young leaves are a stunning burnt orange to terracotta color for about a week and as they reach full size, they turn green over a couple of days. This is a very rare color for Bauhinia. It produces leaves all the time and this means this vine is always full of beautiful color. With its golden leaves, it sure is reminiscent of Autumn.
This vine blooms from May to November. It bears bunches of small flowers that are delicately fragrant in the evenings. The cultivated plants range flower color from pure white to purple and pink, while the wild ones have often white petals with pinkish patches.
Bauhinia aureifolia needs well-drained soil, full light and good humidity to thrive. It will tolerate a light freeze once established and it is very important to protect young plants.
Gold Leaf Orchid Vine also makes a wonderful container plant with staking or support. It is a must for every rare plant collection!
