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

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!

Using SUNSHINE Complete Nutrition System

For hydroponics and potted plants

Q: I recently bought both the 5ml of the sunshine epi and the 100 ml advanced nutrition kit. I read on the paper for the Epi not to use any other strong fertilizers along with this but I was wondering if it'd be alright to use both this foliar spray and nutrition watering together?

A: All solutions in SUNSHINE Booster Nutrition System (NPK-macro and micro-boosters) are compatible.
The only exception is Sunshine-Epi - brassinosteroid bio-stimulant. Epi should be mixed with distilled water separately from other boosters. The reason is, it is very bio-active, and if mixed with other compounds, oxidizes quickly which may affect its performance.

Sunshine-Epi solution must be prepared using distilled water and applied as foliar spray only (it only works on contact with leaves and not through the root system). Epi shows extremely impressive results when you apply it before the application of other nutrients because it increases plant metabolism; so all boosters become even more effective if you spray Epi the day before.

When using Micro- and Macro-boosters, you may mix all components in one watering can/tank (except for Epi), using regular tap water. Besides watering root ball, the macro-micro solution can be also used for foliar spray. It is optional, as in some circumstances growers prefer to keep leaves dry at all times: to stay away from mold, fungus and other issues caused by the wet environment.

Here is an example of Sunshine Boosters Nutrition System application:
1. Daily watering in one can: NPK 25 ml/gal (one of 5, depending on growth stage) + Constanta 5 ml/gal + Ca-Support 5 ml/gal, mixed in tap water
2. Every 2 weeks: spray Sunshine-Epi 2.5 ml/gal - to boost the immune system and growth rate, mixed in distilled water
3. From daily to every 2 weeks: Sunshine-Power-Si 25 ml/gal to protect from diseases and keep pH at 5.5-6.5. Can be used as often as daily and mixed with a daily watering solution (1)
4. As needed: Sunshine SuperFood and GreenLeaf - for correcting deficiencies. Can be also mixed with the daily solution (1)

Make sure to prepare a solution right before use and do not store solution for more than 1 day. Keep concentrates and solutions protected from bright sunlight.
