Seven rules of cold protection for tropicals

Q: I was always wondering how you guys manage to grow true tropical trees in Florida? I live in Puerto Rico and we have Breadfruit trees growing here in a wild... but my sister lives not far away from you, in Orlando, which is much colder, and I wonder if I can get her a Breadfruit tree for Christmas?

A: Your sister can grow a Breadfruit tree in Orlando either in a pot (and bring it indoors during cold periods) or in the ground inside a structure (an elclosed conservatory with heating system). See our customer's Greenhouse in Virginia. Cold protection of tropical plants is a lengthy subject and we have many interesting publications about it in our managine Tropical Treasures and on the website. In a nutshell, when growing tropicals outside of tropical climate, you need to follow these 7 rules:
1. Cut watering to a minimum. Cold+wet kills tropical roots.
2. Water thirsty plants before a cold night. Jucy leaves have fewer chances to be cold-zapped.
3. Wind protection is more important than a temperature drop. Plant tropicals close to a house or surrounded by other trees.
4. Duration of a cold period is more critical than the cold itself. If expecting long cold hours, bring up all available protection resources. Christmas lights or propane heaters - as long as there is a heat source, everything helps!
5. Remove plastic covers during the daytime so plants don't get "cooked" in the sun. Fabric covers are better than plastic.
6. Grow ultra-tropicals in containers and bring them inside the garage or even indoors during the cold.
7. Use SUNSHINE plant boosters and feed your plants well during Summer to improve cold hardiness.

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!

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.

How to grow the biggest fruit on Earth...

Q: When I visited Thailand I bought this huge fruit at the market and the taste was amazing and unique! Now I see you have this Jackfruit tree for sale. I am excited to grow it but not sure if it will survive our winters. I live in Huston, TX. Also are there any special conditions required for successful fruiting?

A: Jackfruit indeed is one of the most fascinating tropical fruit. In spite of reputation being ultra tropical, the tree is not as cold sensitive as everyone believes. Mature trees can withstand light frost for a few hours without significant damage. The only thing, after cold snaps it may be not as profuse producer as in frost-free climates. Keeping Jackfruit in a pot is also an option in colder areas. The tree is quite unique not only about fruit but also about growth habit. The fruit is so large and heavy that the tree has a smart feature to produce only at the base of the trunk. This makes it possible to keep Jackfruit tree at very short height - 6-7 ft tall. We have many varieties of Jackfruit, and all of them can be grown in containers considering regular topping/pruning.

5 secrets of Jackfruit successful production:
1) Frost free temperatures (occasional cold spells are not critical if SUNSHINE-T cold protection booster is used)
2) Soil rich of organic matter (compost, manure, peat moss)
3) Moist soil and regular watering
4) Constant pruning and keeping under 7-10 ft
5) Regular application of fertilizer, microelements and SUNSHINE-Honey for better quality fruit.

How to make a Mango tree bloom and fruit

Mango trees are especially beautiful during spring time when they flush out multi-color new leaves! But you want your mango be not only beautiful but fruitful as well. Here are some tips:

1) Fertilize Mango tree with a balanced slow release fertilizer starting March. Use 1 tsp of granulated fertilizer per 1 gal of soil, or a handful or two for an in-ground tree. You may add one application of foliar spray of a water-soluble bloom booster fertilizer (the one for Roses or Azaleas will work). This will give your tree a good macro-nutrient kick-start.

2) Spray entire tree with SUNSHINE-Superfood solution. This will provide all necessary micro-elements and keep the plant healthy and strong throughout the season. Repeat treatment once a month until harvest time.

3) For sweeter fruit, apply SUNSHINE-Honey solution several times:
- early spring before flowering
- at setting buds
- right at the beginning of setting fruit
- after harvesting, to provide the tree with all good micro-nutrients before resting season.
