"Plants have best friends just like people do. Marigolds help tomatoes and roses grow better. Nasturtiums keep bugs away from squash and broccoli. Petunias protect beans from beetles and oregano chases them away from cucumbers. Geraniums keep Japanese beetles away from roses and corn. Chives make carrots sweeter, and basil makes tomatoes even tastier"
Narrow style trellis for squash, cucumber, melons, beans and other vine crops *Trellising vines increases air circulation to minimize disease problems *Keeps vines and fruits off soil for a cleaner, better harvest. Plant shade crop under trellis to maximize garden space. *Would be great for dividing the garden from the neighbor's yard.
Use cement blocks to edge a garden, and fill the blocks' holes with soil and plant to finish -- low-growing plants like creeping thyme, moss roses or strawberries work well and will not grow high enough to shade or otherwise interfere with garden plants.
