Elephant Foot Yam seed production

Q: Very interesting information about Amorphophallus in your recent newsletter! (which I always enjoy BTW). I would like to purchase those fresh seeds, and I have a couple of questions. Did you have to hand pollinate that flower? I've heard it is not easy to set a fruit. Also, is this an edible variety?

A: From Mark Hooten, the Garden Whiz. These Elephant Yam seeds were produced as a result of hand pollination between two different Amorphophallus paeoniifolius plants grown from entirely different sources. Both plants over ten years old. One corm originated from a traditional Chinese market here in Ft. Myers, while the other came from a Hindu market in Naples. As both were being sold for eating (the prepared corms of the sweet types are a popular Asian vegetable), we know they are of the "sweet" type, not the acrid type which is the commonest in cultivation. The flowering occurred this last April, with the fruit spike maturing in October which is very fast considering it may take up to a year to mature this fruit!
The flowering image shows three different flowers all emerging from a single clump of the Chinese plant which has developed over the years, each flower being a couple of days apart. This is the plant which made the fruit-spike, one of its flowers having been hand pollinated by the Hindu store plant on the other side of the property. Notice all of the large blue flies swarming the fully mature and very stinky flower!

Amazing root growth after treatment of SUNSHINE-SuperFood!

This Sansevieria grandis leaflet planted indoors in a plastic cup was treated with SuperFood once a week, along with regular monthly N-P-K, for a couple of months. On the photo, you actually see not just a ginormous root but a whole new plant started forming through the colossal size root sucker trying to find its way out. A pretty impressive result for a small plastic cup! The cup was protected from the sunlight, sitting inside of a dark planter. The plant received filtered light sitting on a windowsill with Eastern exposure.

Happy Hobby: growing tropicals from seeds

Q: What is the best time to start tropical plants from seeds? Should I wait till spring?

A: If you want to feel happier, get into gardening. If you want to feel God, start plants from seeds and watch New Life grow from a tiny grain. Fall is a perfect time to start tropicals from seed.
Traditionally, people prefer sowing seeds in Spring, especially temperate species for a vegetable garden: tomatoes, peppers, cucumbers... My grandmother up North started them in early Spring in paper cups on a windowsill, then once the temperatures went just above freezing, she planted them out in the garden beds, and that early start always helped her to have the best early crop in the neighborhood.
When we deal with tropical plants, "just above freezing" is not warm enough. Which means you have to grow small babies indoors for quite a while, providing additional heating when needed. Heating pads always work best. If you keep your living space around 75F (ideal for many species), this is a perfect temperature to get your seeds started. Tropical plants are not like annual tomatoes that try to grow through the season as fast as possible. They take time. So the sooner you start, the more chances to get small seedlings just in time when Spring air outside is "warm enough" for those tropicals - at least in 70's.
A great advantage of starting tropical seeds indoors is controlled temperature and moisture. In the plant world, environment extremes are not good for the germination process. Mild conditions of your home or a greenhouse create better chances for successful growth. Seeds won't get overheated in the hot Summer sun, and won't rot because of a sudden heavy rain. Just keep in mind that some species require light for good germination.
For the best seed germination:
- Use only well-drained mix - we recommend special Seed Germination Mix #3, professional grade. Put seeds not too deep (1/2 inch deep or less) to allow air circulation
- Soak large seeds for a few hours with Sunshine-S solution
- Keep warm (75-85F) and in bright light
- Keep soil slightly moist but not soggy
- Apply micro-element booster SuperFood to baby seedlings for vigorous growth

Featured Plant. Flacourtia indica - Governors plum

Flacourtia indica - Governors plum

Governors plum, Madagascar Plum, Batoko palm - is a tropical or subtropical small shrubby tree. It is cultivated in tropical regions as a hedge plant and for its deep red acid fruits resembling small plums. The fruits are about one inch wide and can be eaten fresh or made into preserves. They are sweet and sour, with a texture and flavor similar to a plum. Fruits mature after one to two months from flowering.
The tree is easy to grow, self-fertile and doesn't require much care, not fussy about soil and very forgiving if you forget to water it.
Seeds germinate readily, but it takes a while until the seedling is ready to be transplanted into a big pot or in the ground. If you plant them now, by spring you have a chance to get the little tree ready to go!

Lighting for overwintering tropical plants indoors

Q: Days are getting shorter and darker... I brought my tropical plants indoors for overwintering (I live in Atlanta, GA). Could you give me some advice on what lamps should I use for additional lighting of my plants?

A: Indoor plants are very unlucky: they have to grow in "caves," and everybody knows that plants don't grow in the caves. The luckiest plants win sunny windowsills, but even there they dwell rather like in underbrush under tall trees, where the sun illuminate them only early in the morning or in the evening, and its light is diffused by foliage.
Usually domestic plants are in desperate lack of illumination not only in winter, but also in summer. No light - no growth, no flowering. So, plants need extra light to compensate the lack of illumination in the "room-cave" conditions.
Before you will start any practical actions to help your plants, you need first to decide whether you are going to set an additional illumination, or provide full lamplight. In the case of just additional illumination, rather inexpensive luminescent lamps will do, and you don't have to think about their spectrum. Continue reading...
