Why starting tropicals from seed indoors is better than outside?

Q: I am in Texas, it is getting cold, but I bought these seeds the last two packs, as I didn't want to miss them, was looking for a long time and found you had them. Should I wait until spring to plant them?

A: You can grow tropical plants from seed year round and don't have to wait until warm weather outside. It is, in fact, beneficial to start tropicals indoors in a controlled temperature, moisture and humidity. Seeds of some species are very sensitive to excess water and/or require a certain range of temperature for germination... Besides, it's so much fun!
First, read the basics: Happy Hobby: growing tropicals from seeds

Advantages of indoor growing from seed

It is easier to keep under control indoors:

1) Temperature and Light. Although many tropical seeds require higher temperature and bright light for germination (hot sun may help), it may be hard to avoid overheating and drying out when you put trays in full sun. Using heat pads and additional lighting indoors makes germination smooth, even may take a little longer than in hot sun.
2) Soil moisture. If you ever lost your seeds or tiny seedlings to a heavy summer rain, you sure will appreciate your own moisture-controlled environment! Just make sure to use the right soil mix.
3) Air humidity. Indoor air is drier than outside. It may not be best for some tropical plants, but definitely perfect for seed health - they will never get moldy considering you keep your eye on the plantings.
4) Pre-treatment. Some seeds require scarification (sanding down hard shell), others stratification (cold treatment), but all seeds will benefit from SUNSHINE-S soak before planting. It is easier to do in your home lab. Based on our experience, using Sunshine pre-treatment reduces the risk of fungal damage and improves germination from 30 to 65%.
5) After germination culture. Watching seedlings closely in your home environment and giving them all that is needed for healthy, fast growth - miscroelements and first fertilizer - will help to establish young plants just in time before planting them out in Spring-Summer.

Featured Plant. Bilimbi, Cucumber tree, Tree Sorrel

Bilimbi, Cucumber tree, Tree Sorrel

Ethnic names are: Kamias, Belimbing Asam, Belimbing Buloh, Bimbiri. This rare exotic fruit is very popular in Thailand, Malaya and Singapore. In India, where it is usually found in gardens, the bilimbi has gone wild in the warmest regions of the country. Outside native habitat, Bilimbi is hard to find plant, very few growers produce them, although it is not so hard in cultivation.
The bilimbi is closely allied to the carambola but quite different in appearance, manner of fruiting, flavor and uses. The only strictly English names are"cucumber tree"and"tree sorrel"."Bilimbi"is the common name in India and has become widely used. Many people are more familiar with the close ralative - Averrhoa carambola - Star Fruit, which foliage looks very similar to bilimbi. The bilimbi leaves and taste of fruit are quite similar to those of the Phyllanthus acidus - Otaheite Gooseberry), although these plants are not related. Continue reading...

Portlandia - rich hot chocolate with vanilla

From Mark, the Garden Whiz. Since working in the horticultural field for nearly 50 years, at either nurseries or botanical gardens both in Florida and southern California, I have come into contact with a LOT of very cool plants. So many of them in-fact, that it's becoming increasingly difficult to run across new ones that really make me take special notice. Since being at Top Tropicals for a while now, there are a few species I had not met before which really stand out. Among them are a couple of kinds of Portlandia. Continue reading...

Multi-flowering Hoyas:
from Mark, the Garden Whiz

Q: A few months ago, i was given a Hoya vine. At the time, I was told to not cut-off the flowers but was never told why. However now that it IS flowering, they are so wonderful I would like to. Is there really a reason to not clip them off?

A: Actually, that was very good advise. Unlike most plants we encounter, hoyas develop perennial flower spikes. This means that each spike flowers more than just once! In other words, after the flowers on such a spike have gotten old and fall off, the knobby ended spike remains. Then, after a period of time, that same spike will develop another ring of flower buds. Depending on what kind of hoya it is, these perennial flower spikes may continue to periodically make more flowers for several years! And while the plant will continue to make more of these perennial spikes its whole life, the flowering display becomes better all the time as more and more spikes grow. (By the way, these are technically called "flowering spurs"). So every time a spur might be cut for ornamental purposes, it'll be one less place the vine can flower from in future years.

Season Colors from Kristi, TopTropicals Flower Queen

Q: I live in New Jersey and I have a collection of potted tropical plants in my sun room. Our Fall season comes in bright colors, do you have something with colorful foliage for Fall?

A: For our northern customers it's almost time for the changing of the seasons. It is a very exciting and enjoyable time. The onset of fall means, less humidity, cooler nights and the Fall foliage. Here in Florida we do not get the chance to see the changing of the leaves, except maybe a few like Florida Maple Tree. So we use plants that mimic the season change, for all year round color! These are a few examples of the plants with colorful leaves that you may use for your Fall colors, plus remember - there is always a big list of Fall and Winter Flowering Tropicals!
