Plumeria cold protection

Q: We have a purple-flowering plumeria which resides on our sunny deck during the warm months and then Winter vacations on our back porch where we can close the plastic film windows and where it stays above 50 degrees (overnite) until it can get moved outside again. We live in zone 8+ in South Carolina and I would love to plant it outside. Do you think if we ghost-covered it when alerted that we would have an overnite freeze, that it would survive being planted in the ground and recover to flower when warm? I don't believe the soil in our yard has ever frozen below the top 1/2 inch or so, and never for more than a few hours at a time. What do you think?

A: Plumerias are tropical plants, which means, they need frost-free environment. Even if the ground is frozen only on "the top ½" or so"- this may be enough to kill the plant. From our experience, plumerias can withstand a few hours of windchill frost (not frozen soil), but even if they survive, they may get some branches damage, and recovery may take so long that the plant may not even bloom the next year. So I wouldn't take that risk even with a ghost-cover cold protection. We have customers who grow tropical plants in the ground in colder areas, but they have greenhouse protection: this means, the soil is warm and the air temperature is maintained above 45-50F. For example, this Greenhouse in Virginia.

We recommend to continue growing your rare plumeria in container and move it inside when temperatures drop below 50F (recommended) and for sure when they drop below freezing. Plumeria can take a cold night (a few hours of upper 30's) as long as it is followed by a nice warm sunny afternoon with at least upper 50s. Otherwise, keep it indoors. The good news is, since plumerias are deciduous and have no leaves in winter, low light level won't affect the plant.
Just make sure to minimize watering and keep the plant on a dry side until it starts growing new leaves in Spring. You may continue fertilizing once a week with half-doze of Sunshine boosters - Sunshine TotalFeed. This will maintain the plant healthy and prepare for the blooming season in Spring.

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!

LadyBugs guarding your plants!

Q: I have a bunch of Ladybugs in my garden, I wonder if they eating my plants? Do I need to get rid of them?

A: Ladybug (Harmonia axyridis) is, in fact, one of the best insects you can find in your garden, it is a natural predator that takes care of many bad bugs, including aphids. Keep them happy and bring them to your garden. Ladybugs actually are cultivated as natural pest control, and you can even buy them for your yard, instead of chemicals!

Ladybug larvae eating aphids:

The wonderful insects that dine only on landscape pests and don't harm good bugs or plants are called 'beneficials', and ladybugs definitely fall into this category, but not the way many people think. It's the ladybug's larvae that are voracious predators of soft-bodied problem insects, especially aphids.

Plants that are not for eating

Q: On the website, it says that the pua keni keni tree is toxic. Do you know how toxic? Is it mild irritation or can someone die from ingesting any part of the plant?

A: Pua Keni Keni, Fagraea - seeds (and especially flesh of the fruit) are toxic, so we recommend to always wash your hands after handling them. Obviously, nobody in our team ever tried to eat them to check how toxic they are and if they are deadly.

In general, one must be careful when using plants for purposes other than ornamental growing, especially for consumption. While some obvious edibles (cultivated fruit, vegetables, herbs) are generally safe, but some individuals may have severe reactions - for example, many people are allergic to mangoes; other people may be sensitive to only mango leaves.

A number of plants that have parts commonly consumed for food, have other parts toxic or poisonous. Example: Potato - Solanum tuberosum - has edible tubers feeding the whole planet population, but this plant's fruit is highly toxic and even deadly if eaten. Fruit from a Potato plant look like tiny little green tomatoes since Potato belongs to the same family as Tomato - Nightshade, but it is super poisonous, while Tomato fruit is perfectly edible. So one must watch out and especially educate little children about not tasting anything directly from the garden.

As far as animals concern, in Nature they know what is poisonous and what is edible. Have you ever seen dead birds around a tree with poisonous fruit/seeds? Animals have their own sense for it. So if your concern is for pets, it is normally safe to have pets around plants with irritating or even poisonous parts. However, if your dog has a bad habit of chewing on stuff, you may use extra caution there.

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!
