    Tips & tasks – September

    Cut the dead tops of coneflowers, but leave enough for goldfinches to enjoy the seeds.

    Plant cool-weather vegetables for a fall crop: spinach, mustard and turnip greens, radishes, leaf lettuce.

    Start a new lawn of cool-season grass, such as fescue, or refurbish or repair establish lawns.

    Don’t let the soil of newly planted grass dry out. New grass needs about an inch of water per week.

    It’s still warm, so continue to water and weed garden beds as needed.

    Remove dead foliage, spent flowers and other garden debris; replenish mulch as needed.

    Continue to harvest produce, which may be getting a boost now from slightly cooler weather. Keep watering sage, rosemary and other perennial herbs so they’ll be in good shape to get through winter.

    Prepare to bring houseplants back indoors: remove dead leaves, scrub soil from the sides of the pots, treat for insects. Bring tropical plants in before nighttime temperatures dip to 55 degrees.

Protect banana trees from the cold

We planted a new ‘Texas Star’ banana tree this spring. It’s growing and looks great, but how do we protect it this winter? We live in Middle Tennessee, and it is planted in an open area near a pool.

The ‘Texas Star’ banana is said to be a cold-hardy variety, but it still needs coddling over the winter here in Zone 7a, where temperatures regularly fall below freezing. Once they’re exposed to a couple of frosty nights, the leaves will be reduced to a wilted mush. The important thing is to protect the underground rhizomes. The University of Tennessee Institute of Agriculture grows an impressive Hardy Banana in the UT Gardens in Knoxville, and provides this information for overwintering a banana plant:

Just before frost is expected, use a clean, sharp saw to cut the stems and leaves down to about 8 – 10 inches above the ground, then pile a thick layer of mulch over the crown. They say it’s best to use a heavy mulch (pine bark or hardwood), which won’t blow away easily. Others suggest you cover the stump with the leaves you cut from the plant, or wrap the stump with a blanket, and cover it with an overturned plastic garbage can.

In the spring, remove the mulch after the danger of frost is past, and the rhizome will send up new shoots and grow rapidly when the weather has warmed.

By the way, in this area banana trees are grown for their exotic foliage; it takes a long time to grow bananas, and summer here just isn’t long enough (though if you’ve grown bananas here in Zone 7a, I’d love to hear from you!).
