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.

6 things NOT to do in Summer planting

Q: What a hot summer we have... everything I plant in the ground seem to be unhappy and doesn't seem to grow. I water a lot but it seems not enough? leaves stay droopy or get burned. Are there any secrets for summer planting?

A: End of Summer is still a good time for planting in the South, because there are a few more warm months until winter and your plants need enough time to establish before cold season. However because of high temperatures, a few things should be avoid to reduce stress on the plant:

1. Do not plant mail-ordered plant directly from a box into the ground. Keep it in a pot for a week or two and gradually move the pot from shade into permanent location in full sun.

2. Do not expose to full time direct sun even if potted plant was adjusted to sun. Cover newly planted tree with a shade cloth or simply a bed sheet for a few days. Use bamboo stakes to support the cloth. Even tough, sun-loving plants may get a leaf burn if not established.

3. Do not put mulch too close to the stem/trunk. Keep it 1-1.5 inches away from the plant for air circulation.

4. Do not keep wet. Combination of extreme heat and wet is not good for roots (as well as cold and wet). If you notice that soil dries too quickly - water more frequently but lightly, without creating soggy hot swamp.

5. Do not overfertilize. A handful of slow-release fertilizer is good at time of planting, however do not try to push your plant to grow and do not apply more chemicals or manure until you see a new growth.

6. Do not get discouraged and give the plant some time to establish. In most cases, a new growth starts with roots which you can't see. Sometimes it takes a few months until you see the upper part of the tree suddenly starts growing rapidly.

Care for ultra-tropical plants

Some tropical plants like Durian, Breadfruit, Cacao are rare in plant collections and require true tropical environment for successful growing and most likely greenhouse conditions unless you live in mild tropical climate like Hawaii. These plants are hard to find and are not cheap. They can be shipped to you in original containers via Express mail and usually take trip well as long as there are no delays or overheating (or cold) during transportation. To enjoy your rare plant collection gem, please make sure to follow these recommendations:
- Keep your eye on delivery, track the shipment and make sure package is not left outside in the heat or cold.
- Unpack immediately and put plant in humid, warm environment with filtered light. Remember, "warm" for tropical plant means 78-85F.
- If a plant is wilted, put clear plastic bag over leaves to increase humidity for a few days. Keep the branches covered with clear plastic, in shade only - to avoid overheating.
- Keep soil slightly moist and don't let dry out. These plants like water as well as good drainage.
- Keep plant in original container until recovers from shipping stress. If necessary, re-pot in 2-3 weeks in bigger pot with rich organic potting mix, containing a lot of peat moss, and perlite or bark for good drainage.
- Grow these plants in warm and mild conditions, in filtered light, high humidity, with no temperature extremes. Remember to keep these plants at temperatures above 50F at all times.

Growing Bougainvillea and Plumeria in Florida

Q: I have recently moved from New Jersey to Florida (Orlando area) and I am so excited to start my own Tropical Paradise Garden! A few years ago I visited Hawaii and saw many beautiful colorful Bougainvilleas as well as fragrant Frangipani. Do they grow well in Florida? These are flowers of my dream!

A: Both Bougainvillea and Plumeria grow well in most parts of Florida, especially South and Southwest. Bougainvillea can tolerate some light freeze and can be seen in the streets of Central Florida (young plants require some cold protection for the first year), so it is a very good candidate for your new garden. Keep in mind that unlike in Hawaii, where they bloom year around, Bougainvilleas tend to have a distinctive flowering season which in Florida is winter time - these plants enjoy dry weather that triggers their bloom. To enjoy Bright bougainvillea flowers for a long time, apply balanced fertilizer, prune regularly (this promotes flowering on new growth) and keep established plants on a dry side. Dwarf cultivar Pixie is super compact and can be grown in pots or in a small garden without any pruning! See photo of Pixie on the left.
Plumerias, all-time perfume favorites and symbols of Hawaii, are also residents of many gardens and collections throughout state of Florida. Their cold hardiness is close to the one of Bougainvillea, however keep young plants protected from frost. There are also many new exciting cultivars including multiple "rainbow" colors, and several dwarf varieties, some of them are evergreen - Plumeria obtusa. Plumerias are very undemanding and can stay happy and blooming in a pot and without regular watering. Give them as much sun as possible, and enjoy the fragrance for many months!
