Healthy Plants: Q&A from Mr Booster

How to grow a happy Red Jade Vine?

Q: My Red Jade Vine has the leaf tips turning brown. I water this plant four times a week and I am using a half a teaspoon of miracle grow bloom booster 15-30-15 per 2 gallons, every two weeks. In the beginning I had to water this plant off city water in South Fort Myers. Over the last two months I picked up a dechlorinator buggy plus threw that on my hose and I've been watering it with that but it didn't seem to make a difference. I put this plant in the ground last September. It has three shoots that run into the top of the tree, so it is growing but leaves seem to drop off down low at the base of the vine and the brown tipping running into the top of the plant. But not the newest shoot its leaves are solid green all the way at the top. Thanks for any advice.

A: Mucuna benettii - Red Jade vine - is not the easiest plant to grow, and we are glad your vine is growing well. For those who love this plant but not ready to face all challenges, we recommend its cousin - Camptosema grandiflora - Dwarf Red Jade Vine, which is much hardier and easier plant.
We looked at the photos and these are our thoughts.

1) The top of the plant with green fresh leaves definitely indicates that the plant is generally healthy and vigorous.
2) Dry tips of the old leaves may indicate excess salts in soil, in combination with the summer heat that it went through. Based on your feeding program description, that fertilizer may create a problem. Water soluble traditional fertilizers are EDTA-chelated which often causes nutrients lock up in soil and leaf drop. Try to stay away from that fertilizer for a month and let the rains and/or irrigation water flush the soil for a couple of weeks.
3) Red Jade vine is a very sensitive species. Normally, during hot season it is safe to use traditional fertilizers, especially slow-release granulated. However, with this plant we recommend you to switch to more delicate formula and use only liquid fertilizer.
SUNSHINE Megaflor - Bloom Nutrition Booster will be the best. It is safe to use it as frequent as with every watering! It is amino-acid based, and will be totally consumed by the plant without nutrient lockup.
4) Another cause of dry leaf tips may be micro-element deficiency.
Megaflor booster already has all necessary micro-nutrients in it, plus you may apply some extra: SUNSHINE Superfood.
5) You may continue using regular water for watering (including city water) as long as you use amino-acid based plant food and supplements: they improve soil acidity (what tropical plants like is acidic soil, and Florida soils are alkaline). Additionally, to improve soil acidity which can be critical for this Mucuna species, you may add 1" layer of pure peat moss on top of the soil around the plant. Please keep us in loop how the plant is doing. It is pretty rare species in cultivation and we will be happy to help you to keep it thriving.

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.

7 secrets of a Happy Avocado Tree

Q: I purchased an avocado tree from local garden centers three times but every time it dies on me. My neighbor has a nice tree in his yard and it grows beautifuly. I just purchased one online from you and I need to know what I was doing wrong? Are there any secrets how to make an Avocado tree happy? I have a big garden and several mango trees, but no luck with Avocado...

A: Avocado tree is famous for being such a pain to establish. But once it starts growing, it's growing! We will share a few simple tricks how to make it right.

1. Plant high and provide good drainage. Wet feet is number one reason for failing an avocado tree. It doesn't like wet soil and won't tolerate soggy conditions. Plant it in the highest spot of your yard and slightly on a "hill" (3-4" higher than the surrounding ground).
DO NOT plant Avocado tree in low spots or wet spots of your yard. Save those spots for Cannas or Black Sapote or even a Mango if you want a fruit tree there.
2. Use quality soil. Use only well-drained soil with high content of organic matter. You may add compost to existing sandy soil, or add some professional potting mix that contains pine bark and perlite. Remove rocks from the hole if you see any while digging. Dig a big hole and fill it with a good soil; compact the soil in the hole very well before setting the root ball. Reminder: plant the tree high!
3. Water regularly. After planting an Avocado tree in a nice high spot with a good drainage, start watering it... daily! Avocado likes water, although it doesn't like wet feet! Once you figure out this combination, you've got the recipe of success. Water by hand daily for the first week after planting, then twice a week for couple weeks, then once you notice new growth - you may rely on sprinklers, but keep watching the tree and don't let the soil over-dry. It must be slightly moist, but not soggy.
4. Fertilize. For such finicky tree, we suggest mild formulas of fertilizers. Dry fertilizers may burn roots, especially of a young tree. Even smart-release granulated fertilizers should be used very carefully. The best way to feed your young avocado tree - get a complete set of Sunshine Boosters Pro system. It has all necessary elements for all stages of plant development and never burns the roots. Sunshine Boosters Pro can be used with every watering - no need to guess how much and when. Besides, it is a natural fertilizer based on amino acids - exactly what you want to use on your fruit trees and other edibles!
5. Boost immune system of the tree. Apply Sunshine Epi plant hormone every 2 weeks as a foliar spray to boost immune system and metabolism of the tree and protect it from diseases. Epi makes plants (especially young plants) grow twice faster! It also enhances effect of fertilizers by increasing plant metabolism.
6. Do not prune until you see significant growth. The tree is small and can use as many leaves and branches as possible for photosynthesis and healthy metabolism. We suggest to avoid pruning for at least the first year. On the second year your tree most likely will be covered with flowers (assuming you followed fertilizer program). Let it go through the blooming stage and setting fruit; prune in Fall after fruiting is over.
7. Keep number of fruit to minimum for the first crop. Don't let the small tree exhaust itself. Keep just 2-3 fruit to develop. The next year, no need to control fruit quantity, the tree will develop as many as it can support.
P.S. If you got the tree from a mail-order, remember to establish it in a pot before planting in the ground; move gradually from shade to sun. Follow planting instructions.

Flavor of Feijoa Superfood

by Onika Amell, tropical plant specialist

Q: What exactly is Feijoa - Pineapple Guava? Does the fruit really taste like pineapple? I am curious to know if it is easy to grow.

A: Feijoa is certainly one of the easiest fruit trees to grow as it does not require much care. It is an attractive, evergreen tree or large shrub with dark green, oval, leathery leaves. It has an abundance of uses in the garden and produces lovely edible flowers and fruit! The fruit is eaten fresh, added to smoothies or fruit salad and is also commonly used to make delicious jams and wicked chutneys. Feijoa fruit go a long way in flavor.
This plant is drought tolerant and will grow in almost any soil type. It loves full sun or partial shade and is wind resistant. A lot of gardeners like to grow it as a wind barrier for this reason. It can easily be shaped into a dense, informal hedge or screen that needs very little pruning. Because of this density, it provides excellent shelter for all kinds of wildlife. Butterflies, birds, and butterflies will all love you for growing Feijoa!
Space the plant five feet apart to create a wind barrier hedge. Heat does no not bother it at all and it will also withstand temperatures to 10 degrees F.
The plant gets its names from the delicious perfume it emits. Some folks seem the fruit taste like pineapple, with a slight minty undertone. Others feel the flavor reminds them of juicy fruit gum! The texture is described as smooth and slightly gritty - almost like a pear, but firmer.
If you prefer to grow this plant as a tree rather than a large shrub, simply remove the lower branches up to one-third of the tree's height over a period of time. The Pineapple Guava can grow up to 15 feet wide and tall. They also do really well as a container plant on patios where you can truly enjoy the lovely fragrance of the fruit. It prefers rich, organic, well-drained soil and will need light fertilization every other month in most soils.

We recommend:

Fruit Festival Plant Food - Super Crop Booster
Mango-Food - Smart Release Fruit Tree Booster
SUNSHINE-Honey - Sugar booster
SUNSHINE C-Cibus - Crop Nutrition Booster

Pretty, pink, edible flowers will wow you from May to June, followed in late summer or fall by the delicious and fragrant fruit. An interesting thing about this fruit is that you don't pick it. It falls to the ground when it is ripe. Or simply place something under your tree, like a tarp, and shake the tree. The ripe fruit will fall off. You can store the fruit in your refrigerator for up to a week. And remember! The fruit of the Feijoa is not only a very rich source of soluble dietary fiber, but also an excellent source of Vitamin C, and very rich in antioxidants. They are also low in calories. Each fruit only holds 55 calories.
