Care of mail-order plants during hot summer

Q: I live in California and about a month ago ordered several plants from you, including fruit trees (Carambola, Mango, Avocado) and flowering trees (Xanthostemon, Adeniums, Champaca, Ylang Ylang). They were all doing well until I tried to move them into full sun, when they got leaf burn immediately. Ylang Ylang was doing great in a shade, but I repotted it from 1 gal into 3 gal and it is drooping leaves now. It has been very hot (over 100F) and dry (humidity is less than 25%). Any suggestions?

A: Hot summer can be pretty challenging time for establishing new plants. These are some guidelines to make your summer gardening more successful and rewarding.

1. You can order plants at any time, but keep your eye on your local weather forecast and try to chose cooler periods to schedule your plant shipments. Here at TopTropcals we monitor weather at destinations, and we can also delay shipment per your request until more favorable conditions.

2. During hot Summer months, many plants are still OK to ship, and to be planted, many species are heat tolerant. It's usually safe to ship most succulents, including Desert roses and Euphorbias. Some fruit trees are pretty easy too, like Loquats, Mango, Eugenias. Many flowering trees can take heat: Acacias, Clusias, Jatropha, Sausage Tree, Plumerias and many others. Check our full list of plants suitable for hot and dry conditions. Most jasmines, including Jasmine Sambac and Trachelospermum make also a safe choice for hot weather planting.

3. Use shade cloth or simply white sheets to protect young plants and new plantings from hot sun.

4. When establishing mail ordered plants during hot weather, keep them in shade for longer period of time than average recommended 1-2 weeks. Give them a chance to establish really well. In areas with low air humidity, try to create a simple mist system. It can be purchased in your local Home Depot for only $20 and set up takes only 10 minutes! It makes a big difference and can help you save many plants from hot weather stress.

5. Although it may seem that during hot weather plants need more water due to high evaporation, be careful with watering, and check soil with your finger before watering - don't water if it is still wet. Combination of "hot and wet" can be as harmful for the root system as "cold and wet" during winter. Protect root systems from overheating: covering black pots with white cloth will work. Remember when temperature is above 90F, most of plants slow down their metabolism, which means roots slow down or even stop pumping water and become more vulnerable to overwatering. For the same reason, do not hurry to step up into bigger container if roots haven't filled yet the existing pot.

Cold hardy tropical fruit trees for Luisiana

Q: I've just moved to Louisiana and have been wondering whether it would make sense to plant some tropical fruit trees in our garden. Average lows in New Orleans are 41 deg F in January and February, although we did hit 25 once with the Arctic vortex. I'm interested in litchi, longan, rambutans, and persimmons. Do you have varieties that can tolerate Louisiana's temperature range? I'd love mangosteen but I don't suppose they will survive. Do you have any suggestions on tropical fruit trees that I could try?

A: Average temperatures are for statistics only; it is actual temperatures that may hurt your cold sensitive plant. This is what you should keep in mind when starting your tropical fruit collection:
1) Ultra-tropical plants like Rambutan can not survive winters below 45-50F. However, they can be successfully grown in containers in a greenhouse or moved indoors into a sun room during cold periods.
2) Tropical plants like Litchi and Longan may take some light frost once established. Still, for areas with freeze our advice is - keep them in pots and move inside in case of cold.
3) There is a number of subtropical fruit trees that are hardy enough to take some freeze. Persimmon, Feijoa, Fig, Cattley Guava, Jujube, Kiwi, some Eugenias and others. Please refer to our Tropical Fruit Sensitivity Chart.
4) Remember that plant's ability to survive winter depends on several factors, not only temperature itself. Important factors are: wind protection (chill wind kills rather than low temperature itself), exposure, how close the tree is planted to the house, plant maturity and its overall strength and health. If a plant had received good nutrients during summer, has well established root system, planted in enclosed area protected from winds and has plenty of bright sunlight - it has better chances to survive than a weak plant in warmer conditions.
5) Use SUNSHINE plant boosters for improving cold tolerance of your tropical plant. It only takes a few drops, and only costs $5!

Grafted fruit trees for Hawaiian gardens

Q: Aloha guys, I purchased a Diospyros digyna - Black Sapote grafted var. Black Beauty from you and am checking to make sure it will fruit by itself and not need both sexes. Also checking to see if the grafted atemoya I bought from you will fruit at sea level (where I'm at) or if I should give it to a friend who is above 1,000 so it will fruit? My grafted Maimi soursop is thriving! Looking at getting a grafted jackfruit from you all next.

A: Black sapote Black Beauty does not need a second plant to produce fruit. Grafted trees should be flowering and setting fruit right away, or sometimes on the second year.
Atemoya does not require high elevation for fruiting. It is a hybrid Annona squamosa x Annona cherimola (A. cherimola species prefers higher elevation) so Atemoya is usually is happy at sea level.
Congratulations with your Soursop! It should be really happy in your location.

As for grafted Jackfruits, this is the list of varieties we usually carry. Since many of them are very rare, they sell out quickly once we get new arrivals. If you are looking for a specific variety, I strongly recommend to add it to your wishlist (click on "Notify me when available") and you will receive email from us as soon as we have it in stock, so you will be the first one to know about it!

Our favorite Jackfruit varieties (and also hot sellers)

Black Gold
Borneo Red
Crispy
Dang Rasimi

We also suggest to get a Kwai Muk (while we still have it!) - the most delicious fruit, and it should do well in Hawaii.

Cleanest fruit?

"Dirty" fruit: According to the Environmental Working Group research, Strawberries are top the list of the 12 "dirtiest" fruits and vegetables grown commercially. Spinach is the second, followed by (in order of contamination) nectarines, apples, grapes, peaches, cherries, pears, tomatoes, celery, potatoes and sweet bell peppers. Each of these foods tested positive for pesticide residues and contained higher concentrations of pesticides than other produce. This causes of course chronic health implications. Children are of special concern as younger bodies have greater susceptibility to pesticides than adult bodies, the report emphasizes. Pesticides may induce chronic health complications in children, including neuro- and behavioral problems, birth defects, allergies, asthma, and even cancer...

"Clean 15": Avocados lead 2018's clean fruits and veggies list, that also includes: mangoes, papayas, pineapples, kiwi, sweet corn, cabbage, onions, frozen sweet peas, asparagus, eggplant, honeydew melon, cantaloupe, cauliflower and broccoli.
Obviously, home grown fruit and vegetables are even better. Such fruit as Custard Apples, Sapodilla, Sapote, Jackfruit, Dragon Fruit, Passion Fruit and other rare varieties of tropical fruit, are even better for you because they are not grown commercially, and the choice from your own organic garden is the healthiest for yourself and your family!
Plant them today and get your cleanest fruit tomorrow!

Plants for South Texas and other hot states

Q: Pretty much adore last newsletter. Haven't been buying because our weather here in deep south Texas is so bad it is stunting and killing even the Tamaulipan Scrub! Do you have a cure for that? :) I have every expectation the new grafted Plumeria I purchased from you last year will bloom soon. One of my favorite plants. Thanks again and keep up the good works.

A: Yes, there is a "cure" - using biostimulants that improve drought- and heat- resistance (SUNSHINE boosters), plus the right plant selection. In fact, there is a large number of tropical rare plants that can be successfully grown in hot climates like yours. One of our partners lives in hot and dry Arizona area and has an amazing tropical garden that includes many fruit trees (Mango, Persimmons, Pomegranates, Loquats, etc). Here you can see a few pics from his garden.
Your choice is absolutely right about plumerias. Other easy plants would be Desert roses - Adeniums, and Fancy Euphorbia millii - all these come in so many varieties of colors and bloom throughout most of the year. Our special recommendations for you would be also:

Bougainvillea Dwarf Pixie
Jasmine sambac
Calliandra selloi Pink Lilian
Dracaena marginata Tricolor - Colorama, Money Tree
Hamelia patens Lime Sizzler - Variegated Fire Bush
Jatropha berlandieri - Buddah Belly
Pedilanthus tithymaloides - Devils Backbone
Trachelospermum asiaticum Mandaianum - Dwarf Confederate Jasmine
