...We are introducing our new Series: Top Tropicals Podcast. Growing tropicals and pushing the limits. Watch the first episode:
...Who doesn't like tropical beauty? Everyone wants tropical plants. But not everyone lives in a warm climate. Is it possible to grow tropicals outside of Tropics?
Top Tropicals horticulturist Mark Hooten, who is well known to many
gardeners as the Garden Doc with his
Saturday Plant Clinic, is answering gardeners' questions about how to prepare and protect tropical plants during winter...

Waiting for Arbor Day or the first day of spring to plant a tree is
something of a missed opportunity for those of us who live in the virtually
evergreen world of the tropics and subtropics. Wintertime does not just mean hard
work for tropical gardeners. It is also a time to enjoy the fruits of our
labor. Winter-blooming plants and the visitors they attract - birds, bats and
butterflies - make the garden as enjoyable in winter as any other time of
year.
What a welcome relief: January daytime temperatures in the 70s, dropping to
the 60s at night. This is why I came to live in the subtropics of southern
Florida. The balmy climate of South Florida represents one of the few places
on the mainland United States where tropical plants thrive unprotected
outdoors...

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.

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
