Can You Plant Florist Hydrangeas Outside?

Table of Contents

Florist hydrangeas are popular indoor plants due to their showy blooms and vibrant colors. But can these delicate-looking plants survive outdoors? The answer is yes, but it takes some care and planning. Here's what you need to know about planting florist hydrangeas outside.

Florist Hydrangea Care

Choose the Right Spot

The first step in planting florist hydrangeas outside is to choose the right spot. These plants prefer sites with morning sun and afternoon shade. Too much sun can cause the blooms to wilt, while too little light can stunt growth. Make sure the location also has well-draining soil.

Prepare the Soil

Once you've found the ideal location, it's time to prepare the soil. Florist hydrangeas prefer rich, acidic soil with a pH between 5.0 and 6.5. Amend your soil with organic matter such as compost or peat moss to improve drainage and soil quality.

Water and Fertilizer

To keep your hydrangeas healthy and blooming, make sure they receive ample water and fertilizer. These plants require frequent watering, especially during hot and dry weather. Use a slow-release fertilizer formulated for hydrangeas, and avoid overfertilizing, which can lead to salt buildup in the soil.

Pruning

To maintain the shape and size of your hydrangeas, it's important to prune them regularly. Prune at the right time - for most varieties, this is immediately after blooming. Remove dead or damaged branches as well as any shoots that grow below the graft union.

Hydrangea Varieties for Outdoor Planting

Florist hydrangeas come in a variety of colors and types. While they can be planted outside, some varieties are better suited for outdoor gardening than others. Here are a few examples:

Paniculata Hydrangeas

Paniculata hydrangeas are hardy, heat-tolerant plants that thrive in full sun or partial shade. They produce cone-shaped blooms that start out white or green and then turn pink or red as they mature.

Macrophylla Hydrangeas

Macrophylla hydrangeas are perhaps the most common type of florist hydrangea. They prefer light shade and moist soil, and they produce big, round blooms in shades of blue, pink, purple, or white.

Quercifolia Hydrangeas

Quercifolia hydrangeas, also known as oakleaf hydrangeas, feature large, lobed leaves that resemble oak leaves. They prefer partial shade and well-draining soil, and they produce white or pink blooms in mid-summer.

Arborescens Hydrangeas

Arborescens hydrangeas, also called smooth hydrangeas, are native to North America. They prefer partial shade and moist, well-draining soil, and they produce flat clusters of white or pink flowers in mid-summer.

Planting and Maintenance Tips

When to Plant

The best time to plant florist hydrangeas outside is in the fall or early spring. This gives the plants time to establish before hot weather arrives.

Mulching

Mulch your hydrangeas with a layer of organic matter such as bark or leaves. This will help regulate soil temperature and moisture levels, as well as suppress weed growth.

Winter Protection

In cold climates, protect your hydrangeas from frost damage by covering them with burlap or other breathable fabric. You can also apply a layer of mulch after the first hard frost.

Common Pests and Diseases

Hydrangeas are susceptible to a few common pests and diseases, including spider mites, aphids, and powdery mildew. Inspect your plants regularly and treat any problems promptly.

Planting florist hydrangeas outside can be a rewarding experience, but it requires some care and attention. By choosing the right spot, preparing the soil, and providing adequate water and fertilizer, you can enjoy these beautiful plants in your outdoor garden.
