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?

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!

Chosing a good avocado tree

Q: I'm in coastal Broward County. I'm putting together an order on your web site, and one thing that I would like is an avocado tree. I'd like to have something as close to true "Hass" as possible. Which cultivar does well here in SE Florida, and is most like Hass in texture, creaminess, and flavor? I'm not a big fan of the yellow watery Florida avocados.

A: Mexican type of Avocado have dark skin and buttery texture, while Florida green fruit types (West Indian type, with smooth skin), have lots of delicious melting pulp, so it is a matter of preference.
In coastal Broward county you can grow a wide range of varieties since your climate is very mild, so you don't have select cold-hardy varieties like Winter Mexican, Brazos Belle or Joey, etc. Yet there are many interesting varieties that rare and much more exclusive than Hass, with the same, or even better, quality buttery fruit.

One of the most popular varieties - Brogdon, with red-purple colored pear-shaped fruit, very thin skin, and yellow buttery flesh. It is also very cold hardy.

Very interesting exotic avocado is Kampong - Sushi Avocado - see photo above. The flavor of this fruit very nice, oily, creamy, nutty, reminds of almonds. At the same time, it has solid consistency and if you cut a square it remains a shape of the square. It is the best Sushi Avocado! It tastes great as an appetizer when cut in squares with some shrimp cocktail sauce.

Three collectible varieties:
Anise - leaves that smell like Anise, very rare, the fruit is of excellent quality, creamy and buttery.
Bacon - a large Mexican variety with dark-skinned medium-sized fruits, and a rich creamy flavor. It has exceptional fruit that ripen in late fall and into spring, they are easy to peel and have a light, subtle flavor. Another outstanding feature of the Bacon avocado tree is its angelic sweeping branches which helps keep the tree shorter and easier to pick its fruit.
Nishikawa is a very hot seller! Oval fruit somewhat resembles Hass, but larger, and has very high oil content.
