About Cold Protection...

Q: I have a question, if I'm in Okeechobee Florida zone 9b are there any plants that you sell that would have to be protected at all? I have a lot that I've purchased from you and don't want to lose any of them winter.

A: Sometimes it is hard to guarantee if certain plants are hardy enough in certain area. From our experience, tropical plant performance in non-tropical areas depend on many factors; a lot of times plants appear to be hardier than they are believed to be. Other times, an obviously hardy plant doesn't survive winter. So there always will be a chance of risk involved, while nice surprises are not an exception. We have been testing many tropical species throughout many years of our nursery experience. Wind protection in many cases is more important than temperature. Enclosed sections of your garden provide better chances to survive cold snaps. Generally speaking, here is the list of some plants (not complete list, just examples) that in our experience have been surviving light freezes without significant damage.

Q: I live in San Jose,CA. Got Mango Alphonso 2 yrs back and protected it for a year in a pot during winter. Last spring I planted it and during winter I put a freeze cloth to protect it but it died. How can I make sure it wont die if I buy this time plz?

A: Mango trees are tolerant only to light frost, once established. If it gets below freezing in your area for more than a few hours, and especially if you have numerous nights with frost throughout winter, we recommend to keep mango tree in a pot. This way it can be moved to protected area during cold night. The more established the tree, the more chances to survive colder temperatures.
We also use plant booster Sunshine to increase plants cold tolerance
Cold protection is a lengthy subject. You may also use propane heaters during cold nights.
Here is some more information on cold protection.
Also, we recommend to check out our magazine Tropical Treasures (about pushing the limits of tropical gardening) for a detailed article on cold protection.

Organic remedy for indoor plants insect protection

Q: Winter is coming and I moved my collection of fragrant plants inside the house about a week ago. Today I noticed some aphids on my jasmine. I guess they sneaked in with the plant from the garden where it was a week ago. I don't want them to spread around and get to the nearby gardenia. What should I do to protect my plants from insects indoors?

A: Sometimes bugs attack indoor plants more than those outside in the garden. The main reason is lack of air circulation, lack of sunlight, lack of bug natural predators, and lack of plant's immune resistance due to winter dormancy. So, you need to pay extra attention at your plants health during colder months they spend indoors. Inspect leaves, especially underneath, at least on weekly basis.

If noticed first signs of insect attacks (insects and/or leaf damage such as holes, chewed edges, discoloration, dark or sticky coating), use a simple organic remedy that is handy in every house. Mix in a cup of hot water two tablespoons of any cooking oil: Canola, Vegetable, Sunflower, Olive; Neem oil is the best for this purpose, but it does have a pungent odor (bugs don't like it as well as some people). Add a few drops of dish-soap for better mixing oil in the water. You may add a clove of pressed fresh garlic - bugs hate it! Clean leaves with this solution using cloth, paper towel, and/or spray bottle.

If insects are persistent or your treatment arrived too late when a plant is excessively infested, after cleaning with the oil solution, you may use additionally systemic insecticide sprays sold in garden centers, with active ingredients of pyrethrin, imidacloprid or similar. Make sure to read product label and follow instructions.

However try the organic recipe first, it really works! You may repeat it as needed, as often as you want! See TopTropicals Video on Safe and Easy Pest Control.

Planting instructions for bare-rooted succulent plants

Q: I would like to order a few Adeniums from your selection. You website says "shipped barerooted". What do I need to know about potting these plants before I order?

A: Adeniums do not require much soil; large 4-5" wide caudex plant can be grown in 1 gal pot. After unpacking the plants, position it in a pot, size of root system. Use only well-drained soil with high content of perlite and/or sand. Cactus mix can be used too, although we recommend using our special TopTropicals professional soilless potting mix. Water once and keep in warm (75-80F) place in filtered light. Do not water again until soil dries on surface. Once the plant is established and starts growing new leaves (may take a few weeks), gradually move it into brighter light. Then you can start fertilizing it. You may place shells and lime rocks on top of adenium planting, as these plants benefit from slightly alkaline soils.

More useful information on Grow Lights!

By Michael Aiton, FL: When I was taking classes at Palm Beach State College for my AA degree in Horticulture, what we used in the lab for 'grow lights' was a combination of incandescent and florescent lights to get the full spectrum of red/blue/green light. I saw it as a tried and true method, and cheaper than going out and buying 'grow lights', although they are making incandescent lights harder and harder to get anymore...

Fluorescent lights are by far the most economical and easy choice for houseplants. They come in tubes or compact bulbs (CFL) that screw into regular lamp sockets, and they’re cool enough to put close to plant foliage. Generic fluorescent tubes and bulbs are higher in blue wavelengths, so look for “full-spectrum” or include a mix of "cool" and "warm" bulbs. When in doubt, buy "cool white" products, since white light contains the full spectrum of wavelengths. For maximum effect, position fluorescents about a foot away from plant foliage.

Incandescent lights give off a lot of heat and should be placed farther away from plant foliage. Incandescent bulbs give off more red wavelengths, so they can be used to supplement fluorescent light and balance out the spectrum, especially if you’re trying to encourage plants to bloom. If you want to mix the two, try using a ratio of about one-third incandescent and two-thirds fluorescent by wattage.

Growing Mexican Flame Vine as an annual

Q: While down in Fort Myers a few years ago, I saw this plant - Senecio confusus or Mexican Flame Vine, growing over chain-link fencing. At any rate, I fell in love with the plant then and there, only to later see it up here in Wisconsin, albeit down in Madison at The Centennial House, a noted botanical garden. This has led me to believe it may be possible to use this plant up here in the north as an annual. I could really use the orange coloration in mixed containers, etc. What I would like to try to find out is, will it grow and flower sufficiently within one of our growing seasons up here to make the choice worthwhile? Again, seeing it at Centennial House at least leads me to believe it may be possible. China where the flower was admired for its beauty and believed to have medicinal properties that promoted good health and long life. The Japanese Emperor was so smitten with the kiku flower that he adopted it as his personal crest, and it remains the insignia of the imperial family today. The art of growing and displaying Kiku for the Emperor's garden represented by amazing Imperial styles: Ozukuri, Ogiku, Kengai... Imagine growing out of one stem a single chrysanthemum trained to produce hundreds of simultaneous blossoms in a massive, dome-shaped array.

A: Mexican Flame vine is a good candidate to be grown as annual, thanks to these features:
- extremely fast growing
- it flowers in small size and young age
- long flowering period (2-3 months depending on conditions), throughout early Spring into Summer, sometimes it has a second blooming season by end of Summer.
- we keep large mature plants in stock year round, so you can have blooming size specimen as early as spring once your temperatures reach 65F so the plant will feel comfortable and develop quickly.
- easy to propagate - more plants can be made for next year season.

In winter, a potted plant can be cut back and kept in semi-dormant state indoors - garage, enclosed patio, with temperatures around 50F and above. Some gardeners from North prefer to plant a tropical specimen with a pot into the ground (make sure to add extra drainage holes), and when winter comes, it makes it easier to dig it out and save till warm season.

Grow lights overview

By Benjamin Thorton. If you are an avid gardener living in a place where there are distinct seasons, then you probably know the feeling of dread that sets in when summer ends, because that means that soon you will have to harvest what has grown and put gardening on hold until next spring. However, there is a way how you can continue gardening even when it is cold and snowy outside, and that is to use grow lights to create an indoors garden. So if you want to find out more about what are grow lights and how to use them, then keep on reading...

Growing gardenias indoors

From Brian B, WI: Just wanted to share this photo of one of the plants my parents got from you 3 months ago.

Q: Gardenia taitensis is my favorite gardenia. I would need to keep it indoors under a grow light. Is it worth trying to grow indoors or is really difficult? If so, can you recommend and indoor plant that has big fragrance and blooms often?

A: When growing gardenias indoors, four most important factors must be taken in consideration:

1. Bright light (Southern window and/or proper lighting set up)
2. Proper watering (gardenias love water, but roots are very sensitive to excessive water)
3. Rich organic soil with perfect drainage characteristics, regular feeding with high phosphate component and micro-elements containing Iron or Ferovit.
4. Insect control (inspect underneath leaves regularly and apply systemic or on-contact treatments as needed). See Top Tropicals video on easy insect control.

We definitely recommend Gardenia taitensis (both single and double flower varieties) for indoor culture. Another species, Gardenia vietnamensis, is even easier in cultivation as it takes wide range of conditions and may tolerate slight overwatering (unlike other varieties which are more sensitive). These three mentioned gardenias are somewhat tolerant to low light conditions. Under a proper care, they will grow successfully even in bright shade, however for blooming they require as much light as you can provide. Properly adjusted growing light may be helpful. You may refer to our article about indoor plant lighting in our magazine Tropical Treasures, Issue # 15, or website page.

Musings of a butterfly gardener about the milkweed bug

By Kevin Piotrowicz, FL. This spring I was excited! My milkweed was blooming and going to seed. I have 3 healthy clumps of it, each one with seed pods. I counted the seed pods at one time... 22... I had 22 seed pods on 3 plants! Could it be possible? Could I finally have reached the point that I had a sustainable amount of milkweed growing that would not be decimated by monarch caterpillars?

I was telling my friends, "My milkweed is growing great! I may be able to support a population of monarchs!" There were even a couple of them flying around the yard, landing on the milkweed, and frolicking amount the wax myrtle.

With great joy I watched 3 monarch caterpillars munch on my milkweed. The small plant colony even survived as the caterpillars pupated. Not only survived, it expanded! More shoots came out from the bases of the plants! More flowers! More seed pods! All was right with my garden. The zebra longwings and gulf fritillaries had new friends to play with... But what's this??? ... Continue reading...
