Start a Salad Garden
Clean up a bed and begin sowing your favorite salad greens for fall harvest. Mix together pretty lettuces, or go with the intriguing mix of colors and flavors you get with mesclun.
Stake Tall Asters
Fall-blooming asters look good even if they fall over, but staking them makes for better monarch butterfly watching in October when the plants are in full bloom.
Strawberries begin forming next year's buds in the fall, so give them the special care they deserve. Thoroughly weed your patch, clipping off diseased leaves as you work. Follow up with a balanced organic or timed-release fertilizer.
Hollies, yews, and other evergreen hedge shrubs will have time to develop sound new growth if they are trimmed up now. If you wait too late, the new growth will be too tender to stand up well to winter's cold.
Give them a deep, well-drained bed, and fall-grown carrots will surely impress you with their crisp texture and sweet flavor. Shading newly seeded spots for a few days after sowing greatly improves seed germination.
