When to apply super boost?
Sunshine Boosters: a breakthrough in Winter fertilizing
In the photo: plants are tough survivors. Life can't be stopped even by a brick road!
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

Hardy Plumeria Pudica
Q: I have ordered plumeria pudica from you in March and it is thriving really well here in Rancho Cordova, California. The current temperatures are ranging from 68 to 32 degrees Fahrenheit. My USDA zone is 9b. Does this plumeria pudica survive outside with temperatures dropping in coming winter in CA?
A: From our experience, Plumeria pudica is pretty cold hardy and takes some cold spells in
spite of being a tropical species.
Our trees (well-established) took a few hours of freeze with no
significant damage.
Potted plants are less hardy than in-ground plants. However, their
advantage is, they are easy to move indoors or inside warmer place like garage,
etc. If the temperature stays borderline around 32F for a few hours, the plant
should be safe as long as warm day temperatures follow a cold night. For
longer periods of cold, move the plant inside.
Make sure do not overwater and keep Plumeria on a dry side during
winter, since cold and wet is a bad combination and may cause root problems.
Above is the picture of Plumeria pudica tree growing in Cape Coral, FL
where low temperatures in winter sometimes go down to upper 20's for a few
hours.
To improve cold hardiness of Plumerias and other tropical plants, use SUNSHINE-Epi-T for plant thermal protection and immune system boost.
Make sure to fertilize plants on regular basis to keep them strong and
vigorous. The stronger and bigger the plant, the hardier it is!
