Healthy Heliconia Leaves?

Q: I purchased a heliconia from you a couple months ago. The new growth seems to be doing fairly well, however some of the larger leaves are discoloring around the edges then drying up. It's potted in a large pot with potting soil with 3 holes in the bottom to help with drainage in partial sun under a Royal Palm facing northwest. I'm here in Ft Myers. I was previously watering it every other day with your rapid growth fertilizer 1 tbsp per gallon but I have cut that back to once or twice a week. Please let me know your thoughts.

A: Heliconias and Gingers tend to develop dry leaves if grown in pots, especially ceramic or clay pots, because soil in such pots dries out too fast. These dry leaves are not caused by fertilizer, and you can see lots of new healthy green growth. The plant overall seem to be healthy. Continue fertilizing it with liquid Sunshine Robusta that is great for all wide-leaf tropical species, promotes green, lush foliage, and do not use any additional dry fertilizers!
Another suggestion, try to move the plant in more shady spot. Right now it sits in pretty bright light, this may be OK for established plants in the ground, but potted heliconias are very sensitive to hot sun. They get leaf burn easily.

Why my Avocado is not flowering?

Q: I have 5 avocados. Three of your cold hardy varieties and two others that have all flowered and set fruit in the past. The last two years including this year, not a single one of them has put out any flowers. I am getting lots of new growth like one would expect on a tree too young to flower. The last two years have been very mild with out any damaging frost where in previous years they lost all their leaves due to frost yet started putting out flowers once winter was over. I am confused because they have all flowered and set fruit previous years. Any ideas would be appreciated.

A: From information you provided, and considering the trees get lots of full sun and cold was not an issue, the only explanation is - lack of nutrients. Here is an example.
Very common situation: you get a small 2-3 ft Avocado or Mango tree in 3 gal pot (or even smaller) from a nursery, full of flowers, and sometimes even a small fruit. You bring it home, plant it in the ground or a bigger pot, it looks happy and grows like crazy. Then next year - oops, no fruit, sometimes not even flowers. What happened?
When the tree lived in a nursery, it was provided with all necessary nutrients through the injector systems (continuous feed); or some nurseries may use top dress smart release on regular schedule. Regardless of fertilizer type, professional grower's set up delivers plant food non-stop, on regular basis, with balanced formulas. Plants are not only growing fast but also ready to produce, since nutrients are always available for a full growth cycle.
When you plant a tree in the ground (or larger pot), conditions change. They may be beneficial for the plant: lots of room for roots to establish, hence lots of vegetative growth. Even if you planted it using good quality fertile soil, this soil may contain mostly nutrients responsible for vegetative growth (branches and leaves). Chances are, your soil may be rich in Nitrogen (good for green growth), but poor in other elements responsible for flowering and fruiting (Phosphorous, Potassium, and many important micro-elements such as Molybdenum, Boron, Iron, etc.). Besides, existing soil gets exhausted quickly, and within a year a two, if you don't add fertilizer, flowering and fruiting may be reduced or even stopped. This is why fertilizing program is very important for fruit trees that are expected to bring a crop soon.

We recommend:

- SUNSHINE C-Cibus - Crop Nutrition Booster - balanced food for fruit trees
- SUNSHINE-Honey - sugar booster - promotes more efficient blossoming and pollination, makes flowers bigger and reduces bud drop
- SUNSHINE SuperFood - for improving fruit trees production

Also keep in mind that some fruit trees have a habit of "skipping" a year and may either produce less or not produce at all every other year. In any case, balanced nutrition program can help to fix this "bad habit".

Ylang Ylang leaves after winter

Q: Hi, I purchased ylang ylang tree a couple of years ago. It's grown quite well in my Greenhouse but I'm having some trouble figuring out if I'm watering it too much not enough or if it has an insect. Can you please take a look at my photos and maybe give me a suggestion of what my problem might be?

A: It is normal for Ylang Ylang tree to get dark spots during winter time. Sometimes Cananga gets whole branches darkened (especially dwarf variety fruiticosa), some may even fall off. But they will be replaced with new growth in Spring-Summer. There is nothing wrong with your plant, it is just a reaction to cold and short day light when you keep this plant indoors. These leaves eventually will fall off as the weather warms up, and will be replaced with a new fresh green growth.
Luckily, Cananga is not susceptible to insects and diseases, but its leaves can look unattractive in winter. Make sure to keep watering at minimum until temperatures raise to 80's.
Start fertilizing as soon as new growth appears. We recommend SUNSHINE Pikake - Fragrant Flower Booster, an ultimate fertilizer for fragrant plants.

How to get Canistel tree to produce
without dropping flowers and fruit

Q: My Canistel tree is 3 1/2 years old and is growing very well, see the picture below. It gets hundreds of pea sized "berries" but then they fall off. No canistel fruit. What's wrong?

A: You have such a nice looking tree, it is a shame you can't get any fruit to ripen.
In our experience, Pouteria trees dropping fruit prematurely is a very common problem. There may be one of the following reasons, or a combination of them:
- Cold winters may affect production, and while Canistel is generally pretty hardy tropical plant that can easily withstand short periods of chill, the fruit may never form properly if it had a cold winter.
- Lack of water. Canistel tree is pretty drought tolerant, but for the proper production cycle it needs regular irrigation. Especially during hot summer.
- The tree may be not strong enough; young trees drop fruit very often when they don't have enough "fruiting energy" built up in their system.
Your tree looks well established and vigorous, however, flower/fruit drop is often a sign of insufficient nutrients of particular kind, usually Boron (B) and/or Molybdenum (Mo): either when a tree is too young and not strong enough, or because of poor soils and lack of necessary elements.

Here is what can be done, considering you live in a warm, frost-free climate.

1. Provide regular fertilizing program. We recommend liquid fertilizers Sunshine Boosters that are safe to use with every watering and year around. It is beneficial 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. See also:
- Why liquid fertilizers are better than dry
- Article about benefits of liquid fertilizers.

Use this plant food for your Canistel tree:
SUNSHINE C-Cibus - Crop Nutrition Booster

2. 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.

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.
