About Cold Protection...

Q: I have a question, if I'm in Okeechobee Florida zone 9b are there any plants that you sell that would have to be protected at all? I have a lot that I've purchased from you and don't want to lose any of them winter.

A: Sometimes it is hard to guarantee if certain plants are hardy enough in certain area. From our experience, tropical plant performance in non-tropical areas depend on many factors; a lot of times plants appear to be hardier than they are believed to be. Other times, an obviously hardy plant doesn't survive winter. So there always will be a chance of risk involved, while nice surprises are not an exception. We have been testing many tropical species throughout many years of our nursery experience. Wind protection in many cases is more important than temperature. Enclosed sections of your garden provide better chances to survive cold snaps. Generally speaking, here is the list of some plants (not complete list, just examples) that in our experience have been surviving light freezes without significant damage.

Q: I live in San Jose,CA. Got Mango Alphonso 2 yrs back and protected it for a year in a pot during winter. Last spring I planted it and during winter I put a freeze cloth to protect it but it died. How can I make sure it wont die if I buy this time plz?

A: Mango trees are tolerant only to light frost, once established. If it gets below freezing in your area for more than a few hours, and especially if you have numerous nights with frost throughout winter, we recommend to keep mango tree in a pot. This way it can be moved to protected area during cold night. The more established the tree, the more chances to survive colder temperatures.
We also use plant booster Sunshine to increase plants cold tolerance
Cold protection is a lengthy subject. You may also use propane heaters during cold nights.
Here is some more information on cold protection.
Also, we recommend to check out our magazine Tropical Treasures (about pushing the limits of tropical gardening) for a detailed article on cold protection.

When to apply super boost?

Q: Just wanted to know best time of day to apply super boost as spray and watering? Only listed to make sure night temp doesn't drop below 65F...

A: As a rule of thumb, plant's needs in fertilizers are very low in the cold season because they consume less nutrients during dormancy. For tropical plants, when minimum temperatures drop below 65F - we stop applications of dry (granulated) fertilizers until spring, to avoid root burn.
Liquid Sunshine Boosters are exceptions from this rule to a certain extent, for 2 reasons:
- they are amino-acid based which means, salts do not build up in the soil, and thus will not burn the roots even with slower plant metabolism.
- concentrations/formulas are mild and designed for as frequent as daily watering

1) When a plant goes into full dormancy (drops leaves and does not show any new growth), you may stop fertilizing with any Macro NPK products (both dry and liquid)

2) If a plant is evergreen and continues growing during the cooler period, and especially if it is a winter bloomer, mild liquid fertilizers can be applied, depending on the stage of plant development.
Robusta and TotalFeed are used for vegetative growth and pre-flower.
Megaflor and C-Cibus are used for winter flowering/ fruiting plants during the bloom stage.

See full list of liquid boosters

3) Micro-elements can be used all year round for all plants that are not dormant (do not drop leaves)

4) Always use Sunshine-Epi as a foliar spray to activate immune system and unlock protective mechanisms, BEFORE applying other boosters. It is especially important during Fall-Winter for improving cold tolerance and disease resistance.

5) Always apply foliar spray and/or drench the soil with solutions in morning hours so the plant has time to process the nutrients during daylight when metabolism is the most active.

6) Avoid any dry fertilizers during winter
