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!

RECOMMENDED FERTILIZERS:
Plumeria Top Dress - Smart-Release Booster
Pink N Good Daily Plant Food - Flower Booster
Tropical Allure - Smart-Release Booster

Fertilizing in Winter?

Q: I'm a bit confused about what winter fertilization schedule I should follow in South Florida. For blooming plants, usually, I use a monthly granular bloom booster fertilizer as well as a liquid fertilizer every 10 days or so. Should I continue that schedule in the winter as well? Should I stop fertilizing altogether in the winter? How about fruit trees? What fertilization schedule should I follow in the winter?

A: Here is a general fertilizing schedule for established plants that we follow here in SW Florida.
The rule of thumb is, do not fertilize (with macro- NPK elements) when minimum temperatures drop below 65F and stay at that level for more than 7 days. At this temperature point, most of the tropical and subtropical plants slow down their metabolism and some of them going into dormancy. This means, nutrients are not consumed as much as during active growth period, and built-up nutrient supply within a plant plus whatever is available in the soil is just enough to get by through the winter. So additional fertilizing is not necessary. You may continue micro-element supplements and bio-stimulants throughout the year. In fact, it is highly recommended to do so, to help the plant survive cold spells. These are very effective tropical plant protectors:
SUNSHINE-Epi - Brassinosteroid plant hormone
SUNSHINE-Power-Si - Advanced plant protector with Silicon
SUNSHINE SuperFood - Complex microelement supplement

This rule is applied to both flowering and fruiting plants, in general. However, some species are winter-flowering and winter-fruiting. For those, you can make an exception and provide extra nutrients for flowering and fruiting, as long as the weather stays warm. During cold spells, avoid any NPK fertilizers and use only bio-stimulants and micro-elements. If you apply NPK during cold, it won't be consumed by a plant, build up in the soil, and may create a root burn situation.

In simple words, fertilize from March to October. Give plants some rest from November to February.

Shaping a tree and regrowing branches

Q: I have been so worried about the beautiful ligustrum on my property since my husband decided to "prune" it 2 days ago. He removed about 20 branches from the tree and completely altered the look of the canopy which was so full and lovely 😭. Please advise me if there is anything I can do to help this tree. Will any of the branches grow back? Will the canopy return? It looks practically bare to me now.... so heartbroken. Any advice and reassuring would be greatly appreciated.

A: The good news is, the tree will regrow new leaves and will branch out. The question is, how soon. Ligustrum is pretty slow-growing species and it may take a while until it gets to the shape that is close to the original.
On the other hand, pruning is beneficial almost for every plant, it promotes new growth and bushy shape. So do not panic, your beautiful tree has good chances to become even prettier.
To speed up the process of re-leafing and promote healthy new growth, we recommend the following:

1) Provide extra watering, assuming you have a sprinkler system that covers the yard. Water additionally 1-2 times a week using a garden house, for 1-2 minutes, saturating the soil around the tree and up to a drip line.

2) Apply the following fertilizers:
Tropical Greenhouse Plus - Foliage Booster
Tropical Allure - Smart-Release Booster

3) In addition to fertilizers, we recommend these 2 supplements that will enhance effect of fertilizers and make re-grow process even faster:
SUNSHINEâ„¢ SuperFood
SUNSHINEâ„¢ HumiHum - a natural humate vitamin for plant

4) Mulch well around the tree, keeping it 2-3" away from the trunk

This should help to get your tree back in shape!

Perfecting a Mango Tree

TopTropicals.com

Q: I recently purchased a Mangifera indica - Coconut Cream Mango from you and would like to know if it is possible to keep this in a large pot rather than putting it in the ground. If so, I have a few questions:
1. How large would you expect this variety to get?
2. What are the ideal growing conditions? Full sun, partial sun, etc...?
3. What is the ideal soil?
4. Any specific watering directions for ideal growth?

A: Coconut Cream mango tree has a moderate growth. We've planted one in our garden 4 years ago and it is still under 10 ft tall. This variety should be well suitable for container culture.
1. Keep the branches trimmed after fruiting is over. Mango trees can be grown in 15 to 25 gal containers and can be trimmed under 7-8 ft high.
2. All mango trees need full sun, the more sun the better.
3. Mango needs very well draining soil, ideally with lots of bark and perlite. We recommend our professional soilless mix or a similar formula.
4. Mango trees hate wet feet, and prefer to stay on a dry side: make sure soil in a pot doesn't stay wet; allow it to dry a little between the waterings.
Remember to apply Mango Food fertilizer during warm season for vigorous growth and heavy crop!
