Growing Hydrangeas From Seed – Tips For Sowing Hydrangea Seeds

Hydrangea plants are easy to start from seed. They require very little care and they produce large numbers of blooms each year. You can plant them indoors or outdoors in full sun or partial shade.

The best time to sow hydrangeas from seed is during spring when the weather is warm and sunny. The plants will begin producing flowers soon after germination. Hydrangea seeds need light to germinate so it’s best if you get them into a bright spot with lots of sunlight. If your soil isn’t rich enough, the seeds won’t survive long enough to sprout.

Seedlings take anywhere between 6 months and 2 years before they’re big enough to harvest their own fruit. When they reach maturity, they’ll have small leaves and flowers but not yet fruits. They usually only produce one flower per cluster of five plants. Once the plants are mature, you can either keep them outside in the garden or transplant them into containers where you can enjoy their blooms year round!

How To Grow Hydrangeas From Cuttings?

Hydrangeas are very easy to grow from cuttings. Just take a 6 to 12 inches piece of stem with some leaves on it. Cut the stems 1/4 inch below a node. Dip the bottom 2 inches of it into a rooting hormone then put it into a glass of water with the node dipping just above the water line. You can also dip the bottom 1 inch of the cutting into 2000-8000 nitric acid or use a GA-3 product.
