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.

Tabernaemontana africana - a bush or a tree?

Q: I received a Tabernaemontana africana, but it is not the compact cultivar, from the photo, this is definitely the tree version, not the compact version?

A: The plant in your picture is Tabernaemontana africana and it is a shrub version, not a tree. The plants we have in stock are smaller size but very vigorous so they can be trained into standards.
We have this plant in our garden in the ground (3 years old) and by now it bushed out and remains under 4 ft without any pruning. Just keep in mind this plant requires regular applications of micro-elements, because the species is very susceptible to iron deficiency. The supplement we use, in case you notice any leaf yellowing, is Sunshine-Superfood.

How to grow Parijat indoors in winter

Q: I purchased Parijat plant last year spring. It had good growth in Summer, after that I kept the plant inside the house in winter. A couple of weeks it was ok, after that the plant lost leaves. What is a better idea for growing Parijat plant indoors in Winter?

A: Nyctanthes arbor-tristis, Parijat - is a semi-deciduous plant, which means, it may lose its leaves during unfavorable conditions such as drought, cold, low light and/or humidity. In your case, the plant dropped leaves because of the stress of moving indoors that includes reducing light and humidity levels. When a tropical plant loses leaves during winter, this means it goes into a dormant stage. If this happens, you need to reduce watering and keep the plant on a dry side, water in only when the top level of the soil feels dry to touch. Do not fertilize.
Try to place the plant in a well-lit spot such as a windowsill. If the windowsill and the window glass feel too cold for touch during wintertime, you may place a sheet of a Styrofoam underneath the pot, and a sheet of a bubble-wrap between the plant and the window glass, to create an extra barrier from cold. The plant may re-leaf during wintertime; if not, it may wait until spring, be patient.
Bring it back into outdoor light when minimum temperatures rise above 65F and resume fertilizing.

Agave amica? Polianthes tuberosa...

"A tuberose by any other name would smell as sweet..."
by Mark Hooten, the Garden Doc

A: Recently, we received a beautifully grown batch of Polianthes tuberosa, all in one gallon pots. These are commonly called Tuberose in the cut-flower trade. I was so happy to see them that I could hardly contain myself from exploding with joy! It had been such a number of years since I have even seen this plant that I had nearly forgotten about its existence. I first grew it as a little kid "up north", after seeing it listed in an old-fashioned mail-order catalogue, probably Gourney's. I remember doing things like mowing neighbors lawns and shoveling snow from driveways in-order to save enough money so that toward spring I could order a few things from those plant catalogues...

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).

Monster hybrids of Monstera: juvenile and mature

by Mark Hooten, the Garden Doc

Q: I am a rare plant collector and obtained a very interesing cultivar of Monstera from you that says it's a hybrid Monstera adansonii x obliqua. Is there a named hybrid? The leaves on this specimen that came in 1 gal pot are much larger than the plant I have grown in a 3 gal pot for a few years, under name of Monstera friedrichsthalii.

A: Due to their diversity, it is hard to find verified hybrids in the genus Monstera. M. friedrichsthalii is apparently an old Florida name for what is actually technically M. adansonii. The "primitive" juvenile growth is very different from the much larger more robust form that only occurs when it is allowed time to climb a tree, in which case the foliage becomes very different and much larger with many many more fenestrations (holes) of various sizes. If you visit our Garden Center, you can see the mature form climbing the oak tree in our Shade Garden in front of our office - we use this mature plant for propagation. If you take a cutting and don't let it attach to a bark/trunk and climb upwards, it will quickly revert to the wimpy juvenile form. Seems that even climbing a pole indoors, it never actually develops into the truly mature more complex adult stage. Some juvenile forms growing on a tree if given too much shade, do not develop into the larger mature form. Move it in more light and allow it to climb, and it will look very different, but still is the same plant under different conditions.

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.

Perfect small tree for a pool area

Q: I need a tree for a space that is close to a pool and I don't want a tree that is shedding leaves all year long. I don’t want it too big either. The canary tree caught my attention but I need to know if it is a tree that is dropping leaves all year. If it does then can you recommend another tree? I live in Fort Lauderdale.

A: Canary tree is a good choice. It is free-flowering pretty little tree. It is evergreen and doesn't shed leaves too much especially in your area with mild winter. However, keep in mind that every plant sheds leaves. Even evergreen trees replace old leaves with new ones. Some trees more than others. Flowers also have a seasonal drop. You may check the full list of compact flowering trees suitable for small spaces.

Another great choice is a Dwarf Tree Jasmine, Radermachera - also a free-flowering tree with rose-fragrant flowers and large, architectural leaves that hardly ever drop. It has very dense yet compact columnar shape, and is one of the greatest trees for smaller landscapes.

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.
