Carambola Starfruit FAQ: how dwarf is a seedling?

Carambola Starfruit FAQ: how dwarf is a seedling?

🌟 Carambola Starfruit FAQ: how dwarf is a seedling?



I recently ordered a dwarf Hawaiian star fruit seedling from your glorious stock of tropical trees, however upon doing further research it seems like grafted trees guarantee fruit results while seedlings may vary from what the parent plant was. I was planning on putting it in a planter since it’s a dwarf but I’m worried about the quality of fruit since it’s a seedling. Could you elaborate on that a bit?

✅ You are correct that grafted trees provide the greatest certainty because they are clones of a known variety. Seedling trees can show some variation from their parents.

In this case, however, your seedling is not from an unknown or mixed genetic background. The seeds were collected from a true Dwarf Hawaiian cultivar that was growing among other selected dwarf carambola cultivars, primarily Dwarf Hawaiian and a few Fwang Tong trees. Because both the seed parent and the surrounding pollen parents were dwarf, we expect the offspring to retain many of the desirable dwarf characteristics.

While we cannot guarantee that every seedling will be identical to the parent tree, the chances of obtaining a compact, productive tree with good fruit quality are quite favorable. In fact, seedlings sometimes combine the best qualities of both parents and may even produce fruit that is equal to or better than either parent.
The main difference between a grafted tree and a seedling is predictability. A grafted tree gives you a known result. A seedling introduces some genetic variation, but in this case the variation comes from a pool of carefully selected dwarf varieties rather than from unknown parents.

For container growing, we would still expect your tree to be well suited to pot culture, especially with periodic pruning to maintain size and shape. Many growers actually enjoy growing seedlings because there is always the possibility of discovering an exceptional individual. Carambola is a quick fruit tree: 3-4 years from seed to fruit.

We believe your Dwarf Hawaiian seedling has excellent potential and should make a rewarding container-grown fruit tree.

Edible Landscape: fruit bearing hedge

Photo above: Biquinho Pepper (2 months old plant)

Q: My mom had to remove a hedge for some renovations and after being heartbroken about losing my little bird haven, I've decided to plan on a fruit bearing hedge that offers some privacy and places for the little fledgling to wait for food. Any suggestions? I was thinking blueberries or citrus but open to any ideas.

A: Below are a few suggestions for a fruit bearing hedge planted with fast-growing, tropical species. They will contribute to a nice edible landscape for both your family and the birds - they will be very happy!

Larger size hedge (small trees), grows full-size within 1 season:
- Loquats
- Dwarf Mulberries (very cold hardy too) such as Dwarf Everbearing

Medium size hedge (shrubs or vines), 2-3 seasons to grow full size:
- Black Surinam Cherry Lolita
- Blackberries and raspberries

Low hedge (4-5 ft tall, 1 season, fast growing):
- Biquinho Pepper
- Wiri Wiri Pepper

Citrus is probably not a good idea, not bird's favorite, and blueberries require a special acidic soil here in Florida, so they will need extra maintenance, special soil, and heavy mulching.

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.
