Recently, temperatures in our area have been just what you’d expect for winter in Suwanee – or a good bit warmer. How do you know when it’s right to set out tender veggie seedlings or sow seed directly?
Two conditions are important: average date of last frost in our area and soil temperature. If you’re starting seeds indoors, you want them to be ready to transplant after the last frost date – average April 10 in our area – and when soil temperatures will accommodate the tender plants. Generally, that means you’ll want to start the seeds six to eight weeks beforehand.
For outdoor sowing, check the seed packet for the desirable soil temperature range to allow germination. In either case, test your soil. Inexpensive soil temperature gauges are available at garden supply retailers. – Carol Hassell Resident Master Gardener
