Get Basjoo's Ready For Cooler Temps.
Here in Kentucky, we are finally seeing cooler temperatures at night dropping into the 50's.
Knowing this, we should get prepared for the winter. My first strategy is to keep the corm underneath the soil as warm as possible.
Purchasing black mulch and piling it up around the root zone. When I am done, I should have a thickness of a good eight inches of black mulch covering my corm around my banana. This should extend at least a foot or more around the plant. While the banana is growing, the mulch will keep the soil warm enough to keep the colder temperatures from inhibiting growth. Dont cover the stem with mulch, just the surrounding root zone area.
With the cooler night time temperatures, I am sure to water in the morning hours around 9 am, I do not water after 12 noon because you want to allow plenty of time for the water to dissipate. Cooler temps mean less energy the plant takes in such as water.
I add a few inches of black mulch, then I sprinkle some Organic fertilizer around the plant under the drip line, then I add a huge heaping of mulch around the plant and water. Never fertilize around the stem, sprinkle around the edge from the longest leaf, this is where the feeder roots are. Remember, corms don't eat, roots do.
I want the corm to store up for the winter, the shorter nights tell the plant to slow down leaf growth, and concentrate on corm size. Of course, the larger the corm, the better chance of winter survival.
When I do this, I always extend my season longer than others in my area. My banana's continue to grow when others slow down or stop all together.
I want these banana's to grow as long as possible, because soon it will be time to winterize them, and that is such a sad time. Happy Gardening!!!
