Spring Planting

Now is the time for East Tennessee gardeners to plant cool season crops. It will soon be too late for transplanting cabbage and broccoli, so if you are growing those this year, you'd better get busy. These days, it gets hot enough in May to stop the growth of most brassicas. Your cabbage may not head up, and your broccoli may not bloom.

This is an ideal time to direct seed most leafy greens. Lettuces will take about 75 days, but many mustards, such as arugula and radishes, will be ready in about 6 weeks. Follow the instructions on the seed packages for proper sowing depth, water the seedbed every day if it doesn't rain, and expect most things to germinate within one week.

You can also direct seed beets and carrots, both of which take a little longer to germinate. Carrots can take up to three weeks. Either vegetable should be thinned to the correct spacing (see the back of the seed packet) as soon as most of the seedlings have emerged. Delay in thinning will slow growth and might even limit production. A pair of plastic tweezers is useful for thinning, if you have large hands like I do. Beets will benefit from the addition of wood ashes to their bed, which raises the pH. A cup of wood ashes is sufficient for a ten-foot row of beets. Don't put the ashes directly on the seeds. Instead, work ashes into the soil a few days before planting.

This season, I am growing some vegetables in containers as part of a photography project. If you plan on a container vegetable garden, I suggest using nothing smaller than a twelve-inch diameter pot. Five gallon buckets make good vegetable containers, too, but you will need to drill drainage holes in the bottom. Cover the holes with plastic window screen before filling the container. This keeps snails, slugs and insects from taking up residence in the pot. Remember that container vegetables need frequent watering and fertilizing in order to perform well. You can use soluble fertilizer, time-release fertilizer added to the potting mix, or a granular organic fertilizer.

If you are starting your own transplants, now is as good time to sow tomatoes indoors. Wait another couple of weeks before sowing eggplant or peppers, as these two need more heat. Most transplants will be ready about a month after germination, so plan accordingly.
