I am growing radishes on one square meter of land for a school project. I plan on growing from April 10 to June 1, and harvesting 2 crops in that period. I would be interested in any information you could give me on growing radishes. I am using Burpee seeds. I am interested in any information, from fertilizers and pesticides to how many seeds should be planted together. If you could please respond back to me I would be very grateful. Thank You.

Radishes are an easy crop to grow, so you shouldn't have any trouble. Here are some general guidelines:

For spring growing, choose early season varieties. These are bred to mature quickly in cool spring temperatures. Radishes like a rich, loose, well-drained soil, preferably somewhat sandy. If your soil is heavy clay, lighten it by adding lots of organic matter like compost.

Sow seeds 1/4 to 1/2 inch deep and 1/2 to 1" apart. Once the seedlings are up, you can thin them to about 2 inches apart. Weed and water regularly. They have few pest problems, except maybe flea beetles. If you'd like, you can try covering the plants with a floating row cover to exclude these pests.

If you have good, rich soil, you probably don't need to fertilize. Otherwise, you can fertilize with a balanced, all-purpose water-soluble fertilizer every two weeks or so. Follow label directions.

Good luck on your project!
