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.

Growing mango tree in California
Q: I just ordered a mango tree. I live in Southern California and was wondering if you have any tips on how to acclimate the mango to our climate. I know it is coming from hot and humid Florida to hot and dry Southern California and don't want to kill it because of the differences in climate.
A: Mangos in fact prefer dry conditions rather then humid. It may
be perfect conditions for a mango tree at your place. Plant your tree in a
pot size of the root ball; give it ample water and then let the soil surface
slightly dry before watering again. Keep the plant in bright shade and
gradually move into full sun. Once the tree is recovered from shipping stress, you
may plant it in the ground and make sure to protect from freezing temperatures
in winter. Use Mango Food for quick establishing and better fruit production. More to

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.

Save Coffee from extinct!
The most popular kind of coffee for commercial production, Coffea arabica, is already on the endangered species list. According to research, Coffea arabica plant could become extinct in as little as 60 years.
Coffee requires a forest habitat for its survival. With so much deforestation going on around the world, wild coffee species are being impacted at an alarming rate. Coffee plants grow in very specific natural habitats, so rising temperatures and increased rainfall brought by climate change can make coffee impossible to grow in places the plants once thrived.

More about Mulberries
Customer comment on our Mulberry column in the previous newsletter:
...I planted a Himalayan mulberry, Morus macroura, about six years ago.
For several maddening years, it shot only very long, un-branching tentacles
out there, and it resisted my efforts to force some branching by pruning. It
would send another long, reaching shoot from the tip of the pruned branch,
with NO laterals. Several times, it did this. Finally, two years ago, it broke
buds that looked like they meant it all along those long branches, and in one
season, it fluffed out. The next season it elaborated on this, acting much
more like a proper tree. The fruit is fabulous, three or more inches long, very
sweet, with a rich berry flavor that's more raspberry than mulberry. I
guess it just needed more time. My understanding is that mulberries don't
really like to be pruned, but it needed to happen in this case, along a driveway,
so I reigned it in, and now it's a treasure. Be patient.
Cheers, your admirer, C
