Best Time to Water Vegetables & Companion Plants for Pest Control

Jody asks: water timing and bug-repelling plants. Water pre-dawn—soil absorbs, leaves dry by sun, preventing fungi. Marigolds deter nematodes, aphids, whiteflies. More companions: nasturtium (trap crop for aphids), basil (repels thrips, mosquitoes), chives/garlic (repel Japanese beetles, aphids), mint (contain it), dill/fennel (attract beneficial wasps), rosemary, thyme, oregano.

Diversity confuses pests. Plant borders, interplant, let herbs flower.
