Hydrangea Colors

pink and blue hydrangeas

Add a splash or pop of color to your woodland garden with these shade loving plants. Hues of white, purple, pink, and blue explode into flower clusters in early summer and can last until early fall depending on the hardiness of the specific plant. The flower color of the hydrangea depends on the pH of the soil and the type of hydrangea you have planted.The Penny Mac Hydrangea is popular for having either pink, blue, or a mix with purple blooms depending on the soil pH. Limelight Hydrangea has huge, iconic white flowers that bloom every spring. These late bloomers will bring beautiful colors after all the spring flowering plants open up, which is a nice way to extend the colorful blooms into a new season.

When to Prune Hydrangeas

The best time to prune hydrangeas is in late winter or early spring while the plant is still dormant and leafless. Pruning hydrangeas for winter gives the plant a chance to create new branches and growth in the spring and produce big, huge hydrangea flowers year after year. 

Knowing whether your hydrangea blooms on new wood or old wood is essential when pruning hydrangeas as pruning hydrangeas at the wrong time can cut off next year's blooms. Hydrangea plants that bloom on old wood should be pruned after flowering, while hydrangeas that grow on new wood should be pruned while the plant is dormant.

The Limelight hydrangea or panicle hydrangea should be pruned in the spring. Oakleaf hydrangeas should be pruned just as the flowering period ends in late summer or early fall. 

How to Prune Hydrangeas

You should prune your hydrangeas to encourage healthy growth and tons of summer blooms! The best way to prune hydrangeas is to Prune back stems to just above a fat bud, called a heading cut.Heading cuts redirect growth or shorten small branches. The high point of a heading cut should be about 1/4" above a bud.

Hydrangeas plants are deciduous shrubs meaning they lose their leaves in the wintertime. When pruning hydrangeas, it is important to be aware that not all varieties are pruned in the same way, and different types require a slightly different approach.

How to Deadhead Hydrangeas

The best time to deadhead hydrangeas is when the first set of blooms begin to turn brown and dry. To deadhead hydrangeas, cut the stem below the flower head and just above the first set of leaves. 

Deadheading keeps hydrangeas looking their best by preventing the hydrangea from putting its energy into keeping the flowers alive. This helps encourage healthy growth in the hydrangeas leaves and roots. Read more about deadheading here.

How Much Sun Do Hydrangeas Need?

Most hydrangeas prefer only morning sun, but can tolerate partial sun and partial shade. Morning sun and afternoon shade are best for hydrangeas because the hot afternoon sun can burn the leaves. We recommend a planting spot with at least 2 hours and up to 5-6 hours of dappled sunlight every day.

How Often to Water Hydrangeas

So exactly how much water do hydrangeas need? During the hotter months, hydrangeas should be watered around 3 times per week, depending on rainfall in the area. The best way to tell if your hydrangea needs watering is by using a moisture meter or sticking your finger a knuckle deep in the soil and feeling for moisture. 

When watering hydrangeas, be sure to use a soaker hose at the base of the plant. You don't want to water from above and get the foliage or leaves wet. Wet foliage is at risk of contracting fungal diseases. 

If your hydrangea is planted in a container, water the pot until it comes out the bottom. Never let the plant's roots sit in water as it can cause root rot. If your hydrangea’s leaves look wilted, watering more frequently can help revive the hydrangea. 

Planting Hydrangeas

When to Plant Hydrangeas

The best time to plant hydrangeas is in the Fall followed by early Spring so the plants have the whole growing season to establish roots and produce large flower buds. The best time of day to plant is early morning or late afternoon when the sunlight is subdued, offering protection against heat stress.

Where to Plant Hydrangeas

The best place to plant hydrangeas is in a sheltered location with sunny mornings and shady afternoons . Hydrangeas prefer to be planted in well drained soil that is kept consistently moist and is slightly acidic. Hydrangeas also like to be planted in fertile soil that is nutrient rich to grow plenty of big flower heads in the spring and summer. Plant hydrangeas with other evergreens like hollies or boxwoods. They also look nice with flowering shrubs like gardenias, hostas, or daylilies

Generally, hydrangeas can grow across the United States in USDA hardiness zones 3-9. Keep in mind, they are toxic to humans and animals if consumed. 

How to Plant Hydrangeas

Planting hydrangeas is easy! To start, dig a hole at least 2-3 times the size of the root ball. Take the hydrangea plant out of the nursery pot and loosen up the roots if they are entangled around the root ball. When placing the hydrangea shrub into the planting hole, make sure the top of the root ball is level with the ground and not too deep. 

Backfill with native soil or amended soil such as our Acidic Potting Soil to give the hydrangea a good supply of nutrients and cover with mulch to help retain moisture. For color changing hydrangeas like the Penny Mac, a more acidic pH will change the color of the hydrangea flowers to blue while a more basic pH will change the color of the flowers to pink. Be sure to water thoroughly during the first year of planting to establish strong root systems.

Fertilizing Hydrangeas & When to Fertilize Hydrangeas

To fertilize hydrangeas, spread the fertilizer along the drip line of the branches. Do not apply chemical fertilizers to the trunk or stem of your hydrangeas. 

The best fertilizer for hydrangeas is our Slow Release Fertilizer, which is an all purpose pelletized fertilizer that will slowly make the fertilizer available over the time period of 1 year. That means they only need to be fertilized once a year! After you fertilize, water the hydrangea to ensure that the fertilizer is well washed into the soil and available for the roots of your hydrangea plants.

The best time to fertilize hydrangeas is in early spring so they have the whole growing season to utilize the nutrients that will slowly become readily available to the plant roots. It also gives hydrangeas time for the summertime flower blossoms to open. Fertilize them a second time during the growing season of July. 

Can Hydrangeas Grow in Pots?

Planting hydrangeas in pots is a great option if you do not have a huge landscape or yard to plant them in. Smaller hydrangea plants like the Penny Mac will work perfectly in containers.

Choose a pot with a drainage hole as soil that is too wet can cause root rot. A well draining potting soil for potted plants works best. It has added perlite to help with drainage and aeration. Hydrangea plants in containers will need to be watered more frequently because the material of the planter evaporates water more quickly than if they were in the ground.

Transplanting Hydrangeas

To transplant a hydrangea to a new location we recommend digging up as much of the root ball as possible to give the hydrangea shrub the best chance possible at thriving. The soil at the new planting hole needs to be workable so the roots have room to grow. Make sure to dig the new hole before digging the hydrangea out of its old spot. You want it to spend as little time as possible out of the dirt. You may prune the hydrangea back if it is large and unruly. Dig a trench around the root zone and use your strength to pry it out of the ground. Transport it to the new location, backfill with soil, and water thoroughly. The best time to transplant hydrangeas is in early spring so the plants have the rest of the growing season to re-establish in their new home.
