Helping Citrus and other fruit trees with Nutritional Supplements

Q: Can you recommended a product to help with my citrus? Combating greening and chlorosis.

A: Citrus greening is spread by an insect called the Asian citrus psyllid. The psyllid feeds on the stems and leaves of the trees, infecting the trees with the bacteria that causes citrus greening. Florida Citrus growers dedicated the last decade to researching citrus greening. Officially, currently there is still no cure, however, some Nutritional solutions have shown promising results. To slow the progression of citrus greening in infected trees, nutrients are applied to the leaves and to the roots. Providing better nutrition helps trees fight against citrus greening and enables them to continue to produce quality fruit.

We recommend the following products for use on regular basis:

SUNSHINE Epi is a natural Brassinosteroid plant hormone and a bio-stimulant that may be very effective as citrus greening treatment. It works through plant's immune system and shows amazing results of recovery of weak and sick plants.

SUNSHINE Superfood, a complex micro-element supplement, maintains plant's health and provides vigorous growth.

SUNSHINE-Honey is a basic nutritional complement, it contains essential plant micronutrients Boron (B) and Molybdenum (Mo). These elements are essential to vegetative and reproductive growth, cell expansion, tissue growth, and fertility. A very common problem for most unimproved garden soils is lack of Molybdenum and Boron as soil micro-component. This results in underdeveloped / low quality fruit and/or premature fruit drop. Applying SUNSHINE Honey on your fruit trees will fill that gap and help a fruit tree to form a healthy fruit.

Macro-nutrients should be applied in combination with micro-nutrients on regular basis:

Mango-Food - Smart Release Fruit Tree Booster (works great for all tropical fruit trees)
Fruit Festival Plant Food - Ideal blend designed to improve fruit trees health and vigor, and increase crop yield.

See SUNSHINE Boosters page for the complete list of plant boosters.

How to establish a Mango Tree

Q: I received my mango tree from you on Monday and it looked beautiful. I followed the instructions and kept it out of direct sun. I watered it a little each day when the potting mix was dry to the touch. But the leaves are turning yellow and brown then falling off. Should I have removed the tree from the soil it was packed in?

A: Leaf drop and dry/yellow leaves are normal symptoms of shipping stress. Your mango tree looks healthy overall. Considering you have high humidity now in Louisiana, the plant should recover soon under proper care. These are important tips:

- Keep the plant in bright shade, away from direct sun - at least for a week, then you may start moving it gradually to semi-shade, then to full sun within a few days.
- Do not over-water. If the top of the soil is still moist, do not water until it dries a little bit. Mango prefers to stay on a dry side. From this point, over-watering is more dangerous than under-watering. You may skip a watering if in doubt.
- If it rains every day, make sure to keep the pot under the roof to protect from excessive water.
- Do not remove original soil and do not disturb roots.
- You used the right container size and looks like you have a quality soil with good drainage. Keep the plant in this container at least for a few months. You may step it up only when you see a lot of active growth of branches and leaves - this means, the root system is developing fast too.
- do not fertilize until you see new growth. Then use Mango Food Smart release.
- to help the plant recover from stress, you may use SUNSHINE-E booster and micro-element foliar spray with SUNSHINE-Superfood.

How to fertilize a Mango Tree

Q: I bought a Mango tree from you last month and planted it soon after it arrived. When is the best time to fertilize it? (I am in Florida)

A: We always recommend to wait on fertilizing until the plant is well established. If you planted your tree a month ago and it is doing well, showing new growth, then this is the time to start giving it some food.
For a mango tree, we recommend using 2 fertilizers - water-soluble and granulated:
Fruit Festival Plant Food
Mango-Food
Remember micro-elements that are essential for healthy and vigorous growth:
SUNSHINE SuperFood - plant booster

In Florida, this is the best time right now for fertilizing - while we still have a few months of nice warm weather - active growth period. This will help you Mango tree to establish well before winter rest.

Caring of Soursop in container

Q: I have ordered dozens of trees from you and have a question about Soursop. I have a Soursop in a container and ants and aphids are under new leaves. Do Soursop like little water? I water almost everyday living in southern Los Angeles it's been around 76-80F. I spray the aphids and ants off with a mist setting on my hose. They come back every day. They're only on new leaves...

A: First of all, you don't have to remove the ants iа they don't bother you. Ants are good insects, they do not harm plants; most likely they are attracted by a sweet sap - aphid by-product. Ants clean up a plant, and they may even take care of some bad insects.
It is not difficult to get rid of aphids. Use a safe treatment: in a small spray bottle, mix 1 cup of warm water, 1 teaspoon of dish soap and 2 tablespoons of any cooking oil (if you have Neem oil or Horticultural oil - even better, but prepare, they are pretty stinky). Spray the leaves with this solution to a dripping point. Repeat in a few days if needed. This simple remedy will take care of the aphids.
Daily water may be ok for the plant during hot weather, as long as the soil is not constantly moist. Let the surface of the soil get a little dry between waterings.

Grafted or seedling?

Photo: Mr Barcy meditating before planting Nutmeg seeds

Q: I planted an avocado seed and it sprouted quickly, it has been only a couple months and I already have a small plant. How soon will it produce fruit? Can I grow other tropical fruit from seed?

A: Unfortunately, some fruit trees, including varieties of avocado, mango, lychee, as well as apples and peaches - must be either grafted or air-layered in order to produce, for 2 main reasons:
- seedlings may take a very long time until fruiting, up to 10-15 years
- seedling gives no guarantee on the quality of the fruit or variety
These fruit trees should be propagated as "clones" - both grafted material or cuttings are actually copies of the mother plant and will keep the same fruit qualities. Grafted trees usually start producing immediately.
However there is a number of fruit trees that come true from seed, and take a very short time to start flowering. Jackfruit, Annonas (Sugar Apple, Guanabana, etc), Papaya, Icecream Bean, Eugenias start producing at a young age (3-4 years from seed).

When to fertilize and prune tropical fruit trees?

Q: Can tropical fruit trees (Soursop, Mango, Star fruit, etc) be given plant food any time of year? Also can they be trimmed this time of year/summer?

A: True tropical plants (including fruit trees) need plant food most of the year in real Tropics, where temperatures have very little fluctuations, and active growth season is close to 12 months a year. In subtropical areas when temperatures in winter drop below 65F, plant metabolism slows down, so it is recommended to fertilize only during the warmest period (March through November). So yes, Summer is the perfect time for fertilizing your trees; their metabolism is at the highest point and they can use more food!

Trim your fruit trees right after harvesting. Obviously, you don't want to prune branches before or during flowering or fruiting. The specific time of the year for pruning depends on the plant - every tree has its own flowering/fruiting season. However, avoid pruning right before winter: young shoots promoted by pruning are tender and can be cold damaged.

Plants that are not for eating

Q: On the website, it says that the pua keni keni tree is toxic. Do you know how toxic? Is it mild irritation or can someone die from ingesting any part of the plant?

A: Pua Keni Keni, Fagraea - seeds (and especially flesh of the fruit) are toxic, so we recommend to always wash your hands after handling them. Obviously, nobody in our team ever tried to eat them to check how toxic they are and if they are deadly.

In general, one must be careful when using plants for purposes other than ornamental growing, especially for consumption. While some obvious edibles (cultivated fruit, vegetables, herbs) are generally safe, but some individuals may have severe reactions - for example, many people are allergic to mangoes; other people may be sensitive to only mango leaves.

A number of plants that have parts commonly consumed for food, have other parts toxic or poisonous. Example: Potato - Solanum tuberosum - has edible tubers feeding the whole planet population, but this plant's fruit is highly toxic and even deadly if eaten. Fruit from a Potato plant look like tiny little green tomatoes since Potato belongs to the same family as Tomato - Nightshade, but it is super poisonous, while Tomato fruit is perfectly edible. So one must watch out and especially educate little children about not tasting anything directly from the garden.

As far as animals concern, in Nature they know what is poisonous and what is edible. Have you ever seen dead birds around a tree with poisonous fruit/seeds? Animals have their own sense for it. So if your concern is for pets, it is normally safe to have pets around plants with irritating or even poisonous parts. However, if your dog has a bad habit of chewing on stuff, you may use extra caution there.

How to grow Soursop in a pot

Q: Is it possible to grow soursop in a large pot for life?

A: Soursop, or Guanabana - Annona muricata - is actually one of those tropicals fruit trees that can be easily cultivated in a container. Most plants of genus Annona have compact nature, and these fruit trees usually start production at a young age, as early as 3 years from seed. Annona muricata seedlings take a little longer to fruit, this is why we offer grafted trees, which can start producing right away.
We have a very interesting article about growing Soursop in an apartment. The article was written by an indoor gardener who lives in a very small apartment in Moscow, Russia. He grew this tree from seed and after years of cultivation fun, he finally got several large delicious fruit! It is an amazing story. We have it published in our Tropical Treasures magazine, download the whole issue #7, get a hard copy, or you may download PDF file of the single article.

Dwarf and Condo mangoes - easy mangoes

Q: We leave in zone 6a, could you tell us what is the list of different types of mango plants that could be planted indoor and that they can bear fruits?

A:There is a large group of mangoes called "Condo Mango" - they literally can be grown in your apartment! Those are dwarf varieties that can remain compact in containers with minimal pruning and successfully bear fruit providing bright light and proper care, including plant food.

The best dwarf and semi-dwarf varieties are: Carrie, Cogshall, Cushman, Fairchild, Graham, Ice Cream, Julie, Mallika, Nam Doc Mai, Pickering, Irwin, Jahangir, Juliette, Lancetilla, Little Gem, Manilita, Sia Tong, Torbert, Pim Seng Mun, Super Julie.

They produce juicy, fiberless sweet fruit. Julie is also a very popular dwarf variety, however, it is very cold sensitive and not the easiest to grow. If you get a 3 gal size mango, step it up to 7 gal when the plant reaches 4 ft; you may use a bigger container as the root system grows, up to 15 gal or even 25 gal, space permitting. Trim the tree under 6-8 ft after production season is over (summer-fall).

How soon will Guava tree fruit?

Q: Can you tell me how your Guava trees are propagated? Grown from seed vs. air grafted, etc.? I'm interested especially in the Barbie variety. In particular, I'd like to know how long it takes them to bear fruit - I live in Southern California zone 10b, with good sunlight.

A: Guavas can be propagated by seed, air layers, or grafting. Propagation method depends on the species.
Cattley guavas - Psidium littorale - are usually grown from seeds and start flowering and producing as early as in 2-3 years from seed. Tropical guavas, Psidium guajava - especially named varieties, are propagated usually by air layers, and the rarest varieties like Variegated Honey Moon are often grafted, although they will come true from seed (it's just takes them longer to fruit). Both air-layered and grafted plants start producing right away, usually on the same year of planting or next year, depending on growing conditions.
Barbie Pink is a superior variety, very popular among fruit lovers. It produces large aromatic fruit with a bright pink pulp and very few seeds. This variety is air-layered; in our nursery, these plants start flowering and setting fruit in 3 gal containers.
Plant this tree in full sun and provide regular watering, guavas don't like to dry out. Use fertile soil, with at least 50% of compost, and add some soil conditioning components for better drainage: bark, sand, perlite, etc. Mulch well, just make sure to keep mulch 2-3" away from the trunk. Follow our detailed planting instructions that come with every plant, and you are good to go!
