Healthy Plants: Q&A from Mr Booster

Healthy Heliconia Leaves?

Q: I purchased a heliconia from you a couple months ago. The new growth seems to be doing fairly well, however some of the larger leaves are discoloring around the edges then drying up. It's potted in a large pot with potting soil with 3 holes in the bottom to help with drainage in partial sun under a Royal Palm facing northwest. I'm here in Ft Myers. I was previously watering it every other day with your rapid growth fertilizer 1 tbsp per gallon but I have cut that back to once or twice a week. Please let me know your thoughts.

A: Heliconias and Gingers tend to develop dry leaves if grown in pots, especially ceramic or clay pots, because soil in such pots dries out too fast. These dry leaves are not caused by fertilizer, and you can see lots of new healthy green growth. The plant overall seem to be healthy. Continue fertilizing it with liquid Sunshine Robusta that is great for all wide-leaf tropical species, promotes green, lush foliage, and do not use any additional dry fertilizers!
Another suggestion, try to move the plant in more shady spot. Right now it sits in pretty bright light, this may be OK for established plants in the ground, but potted heliconias are very sensitive to hot sun. They get leaf burn easily.

Leonotis leonurus:
Lion cub's tails looking out of a tall grass...

by Alex Butova, the Witch of Herbs and Cats

...When you drive along the savannah and veld of South Africa, you can see a groups of lion's cubs running among the tall savannah grass. Their ears look out of the grass as bright cheerful spots. The tips of their tails swing by the wind with the grass where the cubs hide. Why so many Lion's cubs? What a surprise! However, these are not the cubs of the King of Animals, these are the tips of pretty flowers endemic to this region...
...A curious thing, the plant continues growing through the flower! This creates a multi-level appearance...
...Leonotis has a long history of medicinal use by traditional African tribes... This plant has a history of being used for its psychoactive properties which have been compared to a mild version of the Cannabis plant... Modern herbal medicine mainly uses this plant for a calming tea infusion...

Cold hardy tropical fruit trees for Zone 9

Q: Can you suggest tropical fruit that can be grown (cold hardy) in Zone 9?

A: There are quite a few tropical/subtropical trees that will grow well in zone 9. Our favorites are: Figs - very cold hardy and drought tolerant.
Loquats - grafted trees that start fruiting right away, reliable producers.
Tropical Mulberry - very fast growing trees that can take freeze, heavy producers.
Macadamia - these trees are of a compact nature, very easy to grow and start producing nuts right away.
Many different varieties of Eugenias - tropical cherries - all-time favorites. Another tropical cherry - Malpighia, or Barbados cherry - starts fruiting in small size under one food tall! Great for containers.
Tropical (Low Chill) Peaches, Nectarines, and Plums. See full list of low-chill, relatively cold hardy fruit trees.
And of course - Bananas!

Don't forget to fertilize your fruit trees to improve their cold hardiness!
