Growing Loquat in container

Q: I purchased a Sherry Loquat tree from you in April of 2020. It got off to a slow start initially, but now is five feet tall with healthy leaf growth! It is in a 15-gallon pot and was brought into the house by October 15th. I live in Zone 6 and kept the plant outside from end of May to October 15th. I have given the tree artificial lights in addition to slow release fertilizer. Can you please advise me on what steps I need to take to get the Sherry Loquat tree to fruit? E.g., lighting requirements, soil pH, soil type, etc.

A: Loquat is normally winter flowering and spring fruiting tree, here in Florida it is usually heavily covered with fruit by April. With a proper care, you may see flowers throughout the winter and they may set some fruit for you. Considering that during this time you have to keep the plant indoors, here are some recommendations:

1. Soil. Well-drained, porous potting mix. Do not use any heavy garden soils. For our plants we use the following mix which is excellent for containers: Abundance

2. Light. The brighter the better. Sunroom would be great, or at least put the tree next to a large window. Extra lighting with grow lights is beneficial. Any type of light will work, you can even use a simple clip-on light, the brighter the better. 8-10 hours a day.

3. Water. Loquat is drought tolerant but for fruiting it will need regular watering; just don't keep soil soggy, let is slightly dry before waterings.

4. Fertilizer program. Use liquid fertilizer. We recommend Sunshine Boosters that are safe to use with every watering and year around - SUNSHINE C-Cibus - Crop Nutrition Booster.
We recommend to switch plants from traditional"slow-release"fertilizer to the liquid one because it makes a huge difference in plant growth and flower/fruit quality and quantity. Sunshine Boosters are scientifically balanced fertilizers that supply all necessary elements for daily plant needs. They are natural and eco-safe, great for any edibles.

5. Micro-elements. These are essential for potted plants, because in containers roots can't reach out to elements that are usually present in soil when trees grown in the ground.

Apply micro-element remedies that are very effective for improving fruit production, especially when flower or fruit drop occurs:
SUNSHINE Honey - promotes more efficient blossoming and pollination, makes flowers bigger and reduces bud drop.
SUNSHINE SuperFood - improves plant vigor and quality and size of flowers
These are all natural, eco-friendly supplements that work great for fruit trees and other edibles.

Which fertilizer is right?

Q: I need some advice on which fertilizer(s) would be perfect for my C​annonball tree and its cousin Heaven's Lotus (Gustavia augusta). ​I also have fruit trees... soursops, mango, etc. and a collection of flowers including pua keni keni, plumeria, bougainvillea, etc. I am wondering if you can recommend a custom fertilizing regimen for my garden (especially the cannonball and the gustavia since they are young).

A: It is a perfect time now to fertilize your plants as they start active growth. We have suggestions on fertilizing programs for your trees. You will find here our recommendations for:

1. Young trees
2. Flowering trees
3. Fragrant plants
4. In-ground grown fruit trees... CONTINUE READING >>

When plants are ready for a meal?

Q: We have an early Spring here in Florida. All plants in my garden flushing out new leaves and buds opening. Can I start fertilizing? I have Mango, Avocado, Peach trees, many medicinal herbs and flowering shrubs: Angel trumpets, plumerias, bromeliads. I prefer mild organic fertilizers; can you suggest something that is safe for edibles and butterflies?

Q: As a rule of thumb, tropical gardeners start regular fertilizing when the minimum temperatures (at night) go above 65F. Keep in mind that Sunshine Boosters fertilizers can be applied year around because they have mild formulas and used with every watering; during cooler period, you water less frequently, so feeding is reduced accordingly. Another advantage of Sunshine Boosters - they are natural (derived from organic amino acids which is the basics of Life). They are safe for edibles as well as pollinating insects.

Here is the feeding plan for your plants:
1. The most universal solution for all plants (both potted and in-ground): get a complete set of Sunshine Boosters Pro system: Advantage-Pro for vegetative growth, BloomBoom Pro for flowering stage, and Ca-Support-Pro + Constanta-Pro as necessary daily supplements. You will need all these 4 components for your garden.
2. Start adding these liquid boosters with every watering according to dozing directions and you will notice amazing growth boost within a week.
3. Apply Sunshine Epi plant hormone every 2 weeks as a foliar spray to boost immune system and metabolism of plants and protect them from diseases. Epi makes plants (especially young plants and those "waking up" from dormancy) grow twice faster! It also enhances effect of fertilizers by increasing plant metabolism.
4. After cool winter temperatures, some plants may develop element deficiencies like chlorosis (yellowing leaves). Additional microelement boost can be provided with Sunshine Greenleaf (iron supplement) and Sunshine Superfood (micro-elements).
5. For additional boosting of flowering and setting fruit, use the following individual boosters:
Sunshine Robusta - for foliage plants and when you need rapid vegetative growth
Sunshine TotalFeed - for Plumerias and other fragrant plants
Sunshine Megaflor - for Brugmansias and other flowering heavy feeders
Sunshine C-Cibus - for improving fruit production and quality
Sunshine Honey - for sweeter fruit (must be applied 4-5 times a year)
6. For young/small plants (seedlings, rooted cuttings) as well as tender tropicals like bromeliads, and orchids - Sunshine Bombino is a perfect choice due to its mild formula.
7. To save money, order complete sets rather than individual boosters; you will be able to safe up to 40%! Sunshine Complete Nutrition System Kits: Combo Kit, and Pro Kit.

If you are a fan of organic gardening, do not use dry fertilizers. While water-soluble and granulated (smart-realease) fertilizers are popular choice in plant nurseries due to their convenience, they are not as safe as liquid boosters because they create salt build-up in soil and have a high risk of overdosing/burning plant roots, especially potted plants, plants at breaking dormancy, at establishing, and at early stages of plant development. Besides, dry fertilizers may affect the taste of your fruit and herbs. See advantages of liquid boosters over dry fertilizers.

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.
