When Should I Prune This Hydrangea?

You don’t need to prune hydrangeas, but pruning lightly after they are done blooming can help encourage a bushier growth and renew an older plant. This hydrangea grows on new wood so you can prune more heavily in the dormant season.

How To Propagate Annabelle Hydrangea

Propagate your Hydrangea from hardwood cuttings in spring to late summer. Cut a 3-5" section and remove all the leaves under the top node. Dip your cutting in a rooting hormone and plant in soil mix. Keep well watered until the root system is established in 4-6 weeks.

Where Should I Plant This Shrub?

Pick a spot that has well drained soil with full sun to part shade in grow zones 4-9. Space 3-4 feet apart to accomodate a 4-6 foot spread.

When planting your Annabelle 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 mid80s or higher.

The Annabelle Hydrangea requires full sun to part shade and prefers moist, well-drained, fertile soil. In hot climates, hydrangeas will do best with some shade. This variety's color is not affected by soil pH. 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. 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.

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.

Annabelle Hydrangeas look great when used as a summer time hedge or even in a woodland garden.
