How to Grow Marigolds: Easy Planting, Care, and Seed Saving Guide

Why Marigolds?

Marigolds are incredibly easy, forgiving, and bloom constantly (April–November in many regions). Their strong fragrance naturally repels insects—no chemical dust needed. Drought-tolerant, they thrive even in clay soil and bounce back quickly from wilting. Perfect for borders, around trees, flagpoles, or Rose of Sharon.
