Hydrangeas are beautiful, flowering shrubs that are popular in gardens all over the world. They come in a variety of colors and sizes, and can be grown from seeds or cuttings. In this article, we will discuss how to plant hydrangea seeds in your garden.

Choosing the Right Seeds

Before you can plant hydrangea seeds, you need to choose the right ones. It’s important to choose seeds from a reputable source, as they will be more likely to produce healthy plants. Look for seeds that are labeled as “hydrangea macrophylla,” as this is the most common variety.

Preparing the Soil

Hydrangeas prefer well-draining soil that is rich in organic matter. Before planting your seeds, prepare the soil by loosening it with a garden fork or tiller. Add compost or aged manure to the soil to improve its nutrient content.

Planting the Seeds

To plant your hydrangea seeds, dig a small hole in the soil and place the seed in it. Cover the seed with soil, and water it thoroughly. It’s important to keep the soil moist, but not waterlogged, as too much water can cause the seeds to rot.

Caring for Your Seedlings

Once your hydrangea seeds have germinated, it’s important to care for them properly. Keep the soil moist, but not waterlogged, and provide them with plenty of sunlight. You may need to thin out the seedlings as they grow, to prevent overcrowding.

Transplanting Your Seedlings

When your hydrangea seedlings are large enough, you can transplant them into their permanent location in your garden. Choose a spot that receives partial shade, and prepare the soil as you did when planting the seeds. Dig a hole that is slightly larger than the root ball of your seedling, and gently place it in the hole. Cover the roots with soil, and water the plant thoroughly.

Caring for Your Hydrangeas

Once your hydrangeas are planted, it’s important to care for them properly. Water them regularly, and fertilize them with a balanced fertilizer every few weeks. Prune your hydrangeas in the late winter or early spring, to encourage healthy growth and flowering.

Dealing with Common Problems

Hydrangeas are generally easy to care for, but they can be susceptible to a few common problems. Powdery mildew can be a problem in humid climates, and can be treated with a fungicide. Japanese beetles can also be a problem, and can be controlled with insecticides or by hand-picking them off the plants.


Planting hydrangea seeds is a great way to grow these beautiful shrubs in your garden. With proper care and attention, your hydrangeas will thrive and provide you with years of enjoyment. Remember to choose the right seeds, prepare the soil properly, and care for your plants regularly, and you’ll be rewarded with stunning blooms year after year.
