Cauliflower Growing Problems: Troubleshooting
Cauliflower is grown much like cabbage, but requires more careful treatment. It is best to start cauliflower indoors where it can be protected from both cold and hot temperatures.

Radishes are a cool weather crop that will tolerate some heat. Sow radishes in the garden as soon as the soil can be worked in spring and plant succession crops every 10 days until the end of spring.

Carrot and Parsnip Growing Problems: Troubleshooting
Carrots and parsnips grow best in loose, sandy, humus-rich soil. Size does not make for more flavorful carrots and parsnips. For best flavor, lift both crops before they reach maximum size. Carrots and parsnips can be sown thickly; later thin both from 2 to 2½ inches apart or more depending upon the variety. Young thinned […] More

Beets and Chard Growing Problems: Troubleshooting
Beets grow best in cool weather. For best fresh eating, harvest beats when they are half grown–about six weeks after sowing. Beets will still be good eating when grown to full size. Thinning beets is important: thin first when roots begin to thicken–the tops will be young and tender and can be served fresh in […] More

You can plant lettuce as soon as the ground can be worked in spring. Grow leafy varieties where the weather is warmer. Lettuce grows well […] More
