7 Strong Reasons to Use Marigold Seeds in Your Garden
What Are Marigold Seeds?
The Tagetes genus in the Asteraceae family includes marigold flowers. Their seeds are the parts that make them reproduce. These seeds are long and thin, and they are usually black with a white or cream-colored tip. They sprout quickly and are known for making plants that are healthy and strong.
There are two main kinds of marigolds that people grow a lot:
- Tagetes patula, the French marigold, grows from 6 to 18 inches tall and comes in yellow, orange, and red.
- Tagetes erecta, or African marigold, grows 1 to 3 feet tall and has bright yellow to orange flowers.
Benefits of Marigold Seeds
Natural Pest Repellent
Marigolds make a chemical called thiophene that keeps nematodes, aphids, and whiteflies away.
Simple to Grow
These flowers are ideal for low-maintenance gardens because they thrive in arid environments and poor soil.
Draw in Pollinators
Bees, butterflies, and other pollinators are drawn to marigold flowers, which makes your garden ecosystem healthier.
