Tip of the day: Growing Plumeria from seed

Q: I purchased a Plumeria from your company. It has done quite nicely and now has produced a seed pod. Please forward me information on how to care for it and use the seeds that may be inside to propagate another plant.

A: Wait until seeds are ripe (seed pod turns brownish). Soak seeds overnight. Use only well drained soil, or cactus mix. Insert heavy end of seed 1/4" into soil, leaving feathered end exposed. Place the pot in direct sunlight. Don't allow soil to completely dry out, but don't let it be soggy. Germination occurs usually within 3 weeks. Do not overwater. For more information on growing Plumerias, see our slideshow guide: Plumerias - perfumed Lei flowers.

Cold hardy tropical fruit trees for Luisiana

Q: I’ve just moved to Louisiana and have been wondering whether it would make sense to plant some tropical fruit trees in our garden. Average lows in New Orleans are 41 deg F in January and February, although we did hit 25 once with the Arctic vortex. I’m interested in litchi, longan, rambutans, and persimmons. Do you have varieties that can tolerate Louisiana’s temperature range? I’d love mangosteen but I don’t suppose they will survive. Do you have any suggestions on tropical fruit trees that I could try?

A: Average temperatures are for statistics only; it is actual temperatures that may hurt your cold sensitive plant. This is what you should keep in mind when starting your tropical fruit collection:

1. Ultra-tropical plants like Rambutan can not survive winters below 45-50F. However, they can be successfully grown in containers in a greenhouse or moved indoors into a sun room during cold periods.
2. Tropical plants like Litchi and Longan may take some light frost once established. Still, for areas with freeze our advice is - keep them in pots and move inside in case of cold.
3. There is a number of subtropical fruit trees that are hardy enough to take some freeze. Persimmon, Feijoa, Fig, Cattley Guava, Jujube, Kiwi, some Eugenias and others. Please refer to our Tropical Fruit Sensitivity Chart.
4. Remember that plant's ability to survive winter depends on several factors, not only temperature itself. Important factors are: wind protection (chill wind kills rather than low temperature itself), exposure, how close the tree is planted to the house, plant maturity and its overall strength and health. If a plant had received good nutrients during summer, has well established root system, planted in enclosed area protected from winds and has plenty of bright sunlight - it has better chances to survive than a weak plant in warmer conditions.
5. Use SUNSHINE plant boosters for improving cold tolerance of your tropical plant. It only takes a few drops, and only costs $5!

Virgo - 8/23-9/22. Virgo is an EARTH sign ruled by the planet Mercury, which also rules Gemini. Virgo is traditionally the Goddess of the Grain, and is associated with autumn. Her plants often have finely divided leaves or stems, subtle odors, or small, brightly-colored flowers. The most beneficial plants for Virgo are high in potassium and help to calm the nerves.

Repotting plants - Fall or Spring?

Q: I re-potted a mango tree into a five gallon pot, it looks great and is starting to bloom. Should I re-pot again while it is blooming or wait until spring? I will be moving the tree into the greenhouse when the temps drop.

A: You shouldn't re-pot any tropical plants in fall. Root system is small comparing to a new, larger pot. And it won't grow during fall-winter period. Therefore, you will have large volume of soil without any root in it, which may provoke rotting. Extra water will most likely cause over-watering of the plant. Wait till Spring to replant it.

How to raise a fallen tree and how to tell if it can be saved

4 steps how to check and save a tree:

1. Checking. To make sure a fallen tree can be restored, check:

a) Roots: If less than a half of root ball is out and has been exposed less than a week, the tree has more chances to recover.
b) Trunk: scratch-test the bark, if it is green underneath, then the tree is alive and worth saving.
2. Trimming. Before lifting, trim the tree. Bush the crown approximately half-way, keeping round shape. If the tree has only an upright trunk left, cut off the broken top. It may bush out from the top.
3. Lifting and securing. Using towing strips or strong thick rope, pull the tree up. For larger trees, you may use a power of a pick up truck (we use our golf carts). Hammer 48" metal stakes ($5 from Home Depot) 3-4 ways around the tree, at 45 degrees, 5 ft away or more depending on tree size, and secure the tree with a strong rope. Make sure to check rubbing points from now on and loosen as needed to avoid bark damage and creating braking points.
4. Maintenance. Water the tree on regular basis and give it a few weeks for new buds to appear in case it lost all its leaves. Some trees may take a few months to recover. Keep the stakes at least for a year.

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.

Carambola (Star Fruit) in winter

A word from our customer:
I just wanted to let you know that the Dwarf Carambola Kari has survived last winter and turned into a nice bushy tree this summer.I have been trying to grow this tree forever it never survived winters here. Then last year you suggested me to plant Carambola in wind protected corner, so I picked a place next to the house,South side very close to the wall. I covered it several times with a sheet on windy days like you said. The tree did lose leaves during winter but it survived and established well. I had my first crop this year nearly 20 fruit!Just thought your other customers wanted to know keep it protected from winds this is the secret,it works! (M., Avon Park, FL)
