To ensure a good crop of basil throughout the summer, stagger your plantings to every two weeks. That way you will always have a good crop ready for harvesting. Protect basil from hungry slugs and snails by mulching under the plants with fireplace ashes. Allow older basil plants to go to seed -- bees love basil!

Petroleum jelly spread around the trunk of citrus trees will prevent ants from taking up residence and farming scale insects. The ants will not cross the petroleum barrier.

Plant Garlic to Protect Roses and Peaches
