Healthy Plants: Q&A from Mr Booster

Fertilizing in Winter

Q: I have many tropical plants in my garden, both in the ground and in pots. I realize it is wintertime and some of them, the Hydrangea, Hibiscuses, and roses are in bloom but the rest of them seem wilty and droopy. Is it alright to fertilize them now, or should I wait for a few days? I have an all purpose tropical fertilizer and a 20-20-20 also. Please advise what to do.

A: During wintertime, tropicals may suffer from low temperatures and lack of sunshine which causes droopy leaves, and leaf loss.
Regardless of the cause and plant condition, you should NEVER apply traditional dry fertilizers during cool months. When cold, dry fertilizers (EDTA-chelated) may create nutrient lock up in soil and damage the roots. Dry fertilizers (both granulated and water-soluble) can be used only during hot season - when min temperatures stay above 65F for at least a week in a row, and daytime temperatures are over 75-80F. During hot, active growth season plant metabolism increases. This provides less chance for a chemical root burn, as the nutrients are used up quickly.

However, liquid fertilizers, as long as they are amino-acid based, can be used year round. From our own experience last winter, we discovered that fertilizing sickly looking plants (with signs of cold damage and root issues) with Sunshine Boosters actually revived those plants. Sunshine Boosters even brought back to life some hopeless specimens. Take a look at this gardenia that grows in our garden (picture above). See full article.
In your case, it would be beneficial to use a mild formula of liquid boosters in combination with Sunshine Epi -a natural plant hormone that boost their growth and helps to cope with cold-, temperature- and low-light-related stress.

These are the products we recommend:
- Sunshine Bombino - add to every watering
- Sunshine Epi - twice a month as foliage spray

Since you grow plants in pots, feeding program is especially essential, because plants are limited with a container size where roots can't reach out to more food in the outer soil. In professional nursery set up with injector irrigation systems, container plants are fed daily (depending on season, more than once a day) with every watering. This is why greenhouse plants are so healthy looking.
So feel free to give your plants Sunshine boosters with every watering, dozing according to the label. During cold period, plants need less frequent watering, so fertilizer input will be balanced accordingly, it will depend on temperature and plant metabolism.

Sunshine Bombino - mild, "pampering" formula for young and tender plants, as well as plants recovering from stress and/or winter damage.

Edible Landscape

Four must-have herbal edibles for your instant Food Forest

Q: What attractive and useful edibles or herbs can I grow in my yard landscape without needing dedicated garden beds?

A: When we think of an "herb garden," parsley and chives often come to mind -plants that aren't particularly showy and typically require a dedicated vegetable garden, space, and regular maintenance. However, creating a food forest in your yard doesn't have to be a complex project. Useful edibles and medicinal herbs can also be exotic and beautiful, enhancing the charm of your landscape. Here are some examples of unusual tropical edibles that are not only stunning ornamentals but also bring delicious goodness to your kitchen.

1. For drinks: Jamaica Tea flower - Karkade Hibiscus

Hibiscus sabdariffa - Flor de Jamaica, Karkade Sorrel, Roselle, or Jamaica Tea flower (Karkade Tea) - yes, many hibiscus species are edible!
- Flowers of Roselle hibiscus are used to make a tea "Agua de Flor de Jamaica". To be exact, those are flower bracts around flowers and seed pods.
- Medical studies show that it lowers blood pressure and has diuretic effects.
- The pleasant flavor is similar to a cranberry juice and it's so good, you may not even want to add any sugar. We make this cold tea every day - perfect for hot summer.
- Karkade Hibiscus grows into a large bush within just one season from seed! Lots of flowers to harvest will last you the whole winter. It can be treated as annual in cooler areas due to its fast growth and same-year harvest. Thrives in full sun.

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.
