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.

🌸 How to Grow Adeniums Without Overthinking It

By Tatiana Anderson, Horticulture Expert at Top Tropicals with Smokey & Sunshine help

✅ Simple rules that actually make them bloom and grow well

• Light - The more light, the better the growth and flowering. Full sun is ideal, but in very hot climates, filtered bright light keeps plants looking healthier.
• Water - Water well, then let soil dry on the surface. Sitting in wet soil damages roots, but letting plants dry out too often can push them into early dormancy.
• Pot and shaping - Use a shallow pot with excellent drainage. To develop a sculptural caudex, lift the plant slightly each time you repot and remove some of the top soil so upper roots become exposed. Over time, this creates a thicker, more prominent base.
• Soil - Use a fast-draining Adenium potting Mix.



Healthy adeniums start with the right foundation - a fast-draining soil mix and careful watering only when dry to avoid caudex rot.


• Cold hardiness - Adeniums are tropical and do not tolerate frost. Keep above 40 F. Brief drops to mid 30s may be tolerated if dry, but cold and wet conditions can damage or kill the plant. In cooler climates, bring indoors or protect during cold nights.
• Indoor winter care - Move plants indoors before cold nights. Place in the brightest spot possible, ideally a south-facing window. Or use additional lighting. Water very lightly and less often, as growth slows. Do not fertilize during dormancy. Some leaf drop is normal in winter.



Freshly grafted adeniums in dormancy - a crucial resting phase. Keep watering low (once a month) and avoid overcare; this is the time to let them rest and etablish.


• Feeding - Adeniums respond best to liquid fertilizer. We apply Sunshine Megaflor Booster with each watering throughout the year. During dormancy, watering is reduced, so fertilizer use decreases accordingly. Consistent, light feeding promotes strong roots, a thicker caudex, and improved flowering.
• Pruning - For multiple blooms, regular pruning is essential. After flowering, cut back long or leggy growth to stimulate branching. Each new branch can produce more buds, leading to a much fuller bloom in the next cycle.

Healthy Plant Food

Plant food for a Star Fruit

Q: I have 2 Starfruit plants from you. One on the left is B10 has a lot of flowers but no fruit is developing. On the rite is Kenjeng. This one has no flowers at all. Both plants are growing very well. Plenty of sun and water. I am located in Boynton Beach Florida. So what to do?

A: Your trees on the pictures look very healthy, congratulations with a great care!
Starfruit, as well as other grafted fruit trees (like mango, avocado, etc) usually flower/fruit easily and readily while in pots in the nursery. Sometimes, once planted in the ground, they may reduce flowering or even stop flowering. What happened?
The answer is simple. In pots, we fertilize them on regular basis. In our nursery, we have fertilizer injector inline with irrigation system that dozes plant food with EVERY watering. In other nurseries, they may also use slow-release fertilizers, but it is still a regular routine to provide plant food to potted plants.
In the ground, especially in Florida poor soils, fruit trees may stop flowering or delay fruiting due to lack of nutrients, or dis-balance of elements in the ground. Without fertilizer, a tree may take extra time to develop bigger root system to reach out for necessary elements, and eventually will start fruiting anyway.
But we want it to fruit soon! The only way to fix the problem is to provide fertilizer on regular basis for a young tree. It is especially important during hot summer months when plant metabolism is fast due to high temperatures, plus nutrients may get washed away with frequent summer rains (like we have in Florida) even if you've added some fertilizer at time of planting.

You can use smart release fertilizer once a month during hot season, this one or similar:
Mango-Food - Smart Release Fruit Tree Booster.

But the most effective way to get a tropical tree to flowering and fruiting, is frequent applications of liquid fertilizer. We use Sunshine Boosters with every watering on our plants. They work great even on hard cases and weak plants, and you see the difference in a matter of weeks, sometimes even days.
We recommend the following fertilizer that contains all necessary elements for young fruit trees: SUNSHINE C-Cibus - Crop Nutrition Booster
