What's so cool about the BloomStruck® Hydrangea? This highly sought-after hydrangea has the ability to change bloom colors to your liking. If you're looking for pink-colored flower heads, you can adjust the ph of the soil so that it's more alkaline. If you're going for purple flower heads, then you can adjust the ph so that it's more acidic. It's really simple. Hydrangeas are happy in acidic or alkaline soils so you can plant one in your yard and let the bloom colors be a surprise!

Look for a maximum growth of 3-4 feet high and 4-5 feet wide. Flower heads begin to develop in early spring and start to really show off late spring all the way to fall.

The BloomStruck® starts out with showy red-purple stems and dark green leaves. It really stands out in your landscape even without the flower heads it produces. What also makes this hydrangea so special is its hardiness. The Bloom Struck is resistant to powdery mildew, heat tolerant, and has extremely strong branches and stems which can hold up the colorful flower heads.

How To Prune A Bloomstruck Hydrangea

You don’t need to prune hydrangeas, but pruning after they are done blooming can help encourage a bushier growth and renew an older plant.

What Are Good Companion Plants For This Shrub?

Heuchera, hosta and pansies all do well in mixed gardens with the Bloomstruck.

How Do I Plant This Hydrangea?

Plant in early spring or fall in a spot with well drained soil and full sun to part shade conditions in grow zones 4-9.

When planting your Bloomstruck Hydrangea be sure you have the right location and conditions for your new plants to thrive. Spring and Fall are ideal times to plant Hydrangeas. Avoid planting hydrangeas in summer when temperatures are mid 80s or higher.

Planting

The Bloomstruck Hydrangea requires full sun to part shade and prefers moist, well-drained, fertile soil. In hot climates, hydrangeas will do best with some shade.

Watering

Keep the soil moist, but not saturated, especially in summer and in the first year after planting. Throughout its life Hydrangeas will do best with a deep watering once weekly during hot temperatures.

Mulching at about 3 inches deep is highly recommended for hydrangeas. Mulching will cut back on watering needs and protect your plant in extreme temperatures.

Fertilizing

If you have alkaline soil and want a blue hydrangea, be sure to amend your soil. To acidify your soil, amend with aluminum sulfate or elemental sulfur. If you are seeking a pink color, add lime several times per year.

Choose a slow release fertilizer for flowering plants. Fertilize once in spring after the last chance of frost and again in early summer for best results.

Maintenance

You don’t need to prune hydrangeas, but pruning after they are done blooming can help encourage a bushier growth and renew an older plant. 

Learn when to prune your flowering shrubs.

The best way to prevent disease and pests is by providing the appropriate care for your plants. Proper location choice, watering, and fertilization are the keys to your success. You can treat mites, scale, whiteflies, and aphids naturally with neem oil or insecticidal soap. For severe infections you can use pesticides like carbaryl, also known as Sevin. Fungal infection can be prevented by making sure the planting site has good drainage and by avoiding overhead watering. Fungal infections can be treated with a fungicide. Generally, treating fungus after infection isn't effective so if you have problems with other plants or in a prior year, treat preventatively in early spring.
