How To Grow Hydrangeas


Hydrangeas are one, if not the prettiest shrub which fully blooms during summer and fall.

Hydrangeas loves most kind of soils – acidic, slightly alkaline, and neutral. It can grow either with partial or full sun exposure.

It falls on USDA zone 3-9 and can add a splash of vibrant colors in any garden – blue, purple, pink, or white depending on the soil’s PH level.

The best part is that multiple colors of blooms can exist in a single hydrangea plant!

Soil Superstar

The hydrangea loves soil that holds moisture really well. Just keep the soil moist and for best results, add compost to the soil. Take note of the root ball size. This should be the gardener’s reference for digging. The depth will exactly depend on the root ball size while the width should be twice or thrice bigger. Plant the hydrangea and add soil, filling the dug hole halfway, water, and once the soil absorbs the water, fill the hole with more soil. Plant the hydrangeas at least three feet apart from each other.

Sun for Flowers

Hydrangeas love the sun as much as they love the soil. However, for optimum results, facilitate full sun exposure at the beginning of the day and reduce to partial sun exposure in the afternoon. Hydrangeas are best planted during spring and autumn.

Water Wonder

Hydrangeas need plenty of flowers right after planting. It loves moist soil so make sure that it gets plenty of water during the first two years and whenever it gets warm.

Keeping Hydrangeas Feed. For rich soils, gardeners can totally skip fertilizers. However, for sandy soils, fertilizer is recommended once in spring or in late winter. However, gardeners need to make sure that they do not over-feed the hydrangeas because this will result to healthier leaves but low quality blooms.

No Fear for Fall. Hydrangeas need extra care during autumn. Gardeners should cover part, or for the best result, the whole plant with mulch and organic matters except for maple leaves.

Prettily Pruned. Gardeners can prune their hydrangeas before August 1. They should remove dead wood at the beginning of spring or as summer ends. Just cut the oldest stem for healthier and more branches and fuller leaves. Do not get rid of faded blooms until the beginning of spring.

Pest-free. Common hydrangea pests and diseases include gray mold, powdery mildew, ringspot virus, slugs, rust, and leafspots. There are different remedies for specific pest or disease such as pesticides, washing the leaves with soap, manual pest removal, setting up traps for slugs, using slug pellets, fungicides, or full air exposure for the hydrangea.

The best time for hydrangea harvest is when it has reached a papery texture. Gardeners need to remove the leaves before they hang the blooms upside down in any warm, dark, airy, and dry area. They need to keep it away from direct sunlight once it is dried up.
