What is the Hydrangea Serrata?
Hydrangea Serrata or mountain Hydrangea, are known for their flattened flower heads. You might have seen their famous counterpart, H. macrophylla, which has bigger leaves and flowers and their shrubs are less compact.
But flowerheads of the mountain variety are featured by smile florets in the center, having sterile showy florets on the margins. Straight Hydrangea Serrata bloom lace-cap flowerheads. Flowerheads grow to a maximum of 8” in diameter.
Just like all other varieties of Hydrangea, the color of the flower of this plant changes with soil pH levels. The higher the acidity of the soil, the bluer the flowers bloom.

How to grow Mountain Hydrangea
The first thing that comes to mind when speaking of growing a plant, is pruning. For the case of Hydrangea Serrata, this is not a big concern. Although, you should take care not to trim away old wood when trimming because, in most cultivars, flowers bloom only on old wood; so, cutting away old wood will sacrifice future blooms.
Prune away dead or damaged wood in the early spring. Before summer ends, cut away one-third of old wood; cut as close to a double-bud as possible. Shorthand pruning flowers when they are bloomed will also encourage vigorous flower growth.
clean the branches broken in the winter months, especially branches that have fungal infections for mildew. Strong winds are not good for your hydrangeas.
How to plant Hydrangea Serrata
The next item from everything you should know about Hydrangea Serrata is the way you can plant this beautiful flower.
There are three important factors when planting Hydrangea Serrata: shade, soil, and moisture. The Hydrangea Serrata shrubs can survive in extreme cold, but dry and hot climates are not what they can survive. For those who live in warmer climates, we suggest planting the shrub in places with partial shade, like where only afternoon sunlight hits. If you live in a colder place, full sun is highly recommended.
The Hydrangea Serrata also needs rich soil to grow strong roots and stems. To trap moisture, ease soil temperature, and protect against weeds, you can apply mulch around the planting area. Do it using a layer of shredded bark, peat, or compost.
