Start the seeds inside about 4 weeks before the last spring frost. Starting them inside will give you an early bloom. Or sow the seeds directly outside after all danger of frost is gone. Choose a spot with full sun or partial shade. Because zinnias grow only about 2 ½ to 3 inches tall, they make a great border. Water well and often. Once zinnias begin to flower, make sure to cut off old, dead, or fading flowers to prolong their bloom. Fertilizing zinnias will also increase their bloom.
Cut off faded blooms to encourage more growth.
Zinnias are nectar-rich therefore great for pollinators and attract bees, ladybugs, Japanese Beetles, hummingbirds, and wasps.
