Hydrangea is planted as a potted plant.

Planting Potted Plants in the Garden:

  • Hydrangeas may be planted in partial shade or in full sun. In the south shade is better for them. In the north full sun is better. Some varieties are more tolerant of sun than others. Select a location with soil rich in organic matter. Avoid planting too close to trees which will compete with them for moisture.
  • Prepare the bed by turning the soil under to a depth of 6-12, inches removing any debris, and lightly raking as level as possible.
  • The addition of organic matter (leaf mold, compost, well-rotted manure) benefits all gardens and is essential in recently constructed neighborhoods.
  • Plant on a cloudy day or in late afternoon to reduce transplant shock.
  • Dig a hole for each plant large enough to amply accommodate the root ball.
  • Unpot the plant and gently loosen the root ball with your hands to encourage good root growth.
  • Place the top of the root ball even with the level of the surrounding soil. Fill with soil to the top of the root ball. Press soil down firmly with your hand.
  • Use the plant tag as a location marker.
  • Thoroughly water and apply a light mulch layer on top of the soil (1-2 inches) to conserve water
  • Keep weeds under control during the growing season. Weeds compete with plants for water, space and nutrients, so control them by either cultivating often or use a mulch to prevent their germination. 
  • Mulches also help retain soil moisture and maintain even soil temperatures. For perennials, an organic mulch of aged bark or shredded leaves lends a natural look to the bed and will improve the soil as it breaks down in time.  Always keep mulches off a plant’s stems to prevent possible rot.
  • Careful watering is essential in getting perennials off to a good start. Water thoroughly at least once a week to help new roots grow down deeply. Soil should be damp at about 1 inch below the soil surface. You can check this by sticking your finger in the soil. Water early in the morning to give all leaves enough time to dry. One inch of rain or watering per week is recommended for most perennial plants. You can check to see if you need to add water by using a rain gauge.
  • After new growth appears, a light fertilizer may be applied. Keep granular fertilizers away from the plant crown and foliage to avoid burn injury. Use low rates of a slow release fertilizer, as higher rates may encourage root rots.
  • “Deadhead”, remove spent flower heads just below the inflorescence (the cluster of flowers) to encourage continuous flowering and prevent seed development. The flowers of some varieties dry nicely on the plant.
  • In colder regions, apply another layer of mulch (1-2 inches) after the ground freezes in fall. Evergreen boughs (from Christmas trees) provide additional protection. Remove this mulch in the spring.

Hydrangeas make beautiful cut flowers and add a nice touch to borders. Many varieties are also great for containers.

Pruning is very important and will vary depending on the species of the plant:

Hydrangea quercifolia (Oak Leaf Hydrangea) bloom on last year’s wood, only prune any pruning that needs to be done is just to control height. Prune right after it is finished blooming or just remove the dead flowers.

Hydrangea macrophylla (Big Leaf Hydrangea): This species blooms on last year’s wood. Any pruning that needs to be done is just to control height. Prune right after it is finished blooming or just remove the dead flowers.

Hydrangea serrata ( Mountain Hydrangea): This blooms on last year’s wood. Prune right after it has finished blooming or just remove the dead flowers.

Hydrangea paniculata (Peegee Hydrangea): This blooms on this year’s wood. Prune in early spring before new growth starts.  For the largest flowers, thin to 5-10 primary shoots. Note that the weight of the flowers can cause the branches to arch downward.

Hydrangea arborescens (Hills of Snow Hydrangea): This blooms on this year’s wood. Prune in early spring before new growth starts. Hills of Snow hydrangea may be left unpruned (except for removing dead branches). In this case it will produce many smaller clusters of flowers.

Rated 1 out of 5 by from Sad sister, same circumstance, sad summer I bought two of these plants last spring and they were by far the biggest disappointment of the year. I’m a new gardener and I have read that hydrangeas are tough and I knew that they might not flower the first year, but I wanted to add more greenery to my balcony rose garden. I babied my roses and I pampered my hydrangeas, tomatoes, and all my other little children from March until September, but the hydrangeas never really stood a chance. Probably the most perplexing of all is the plant below pictured on the left and right, which given all the same conditions as it’s sister, died almost immediently after putting on my balcony. As it started to whither I tried moving it for more sun hour to less sun hours but nothing worked. I starred at it endlessly on Saturdays counting the hours of light the two plants received and while one grew the other withered. I was so disheartened but I thought at least this year, I’d have the 1 hydrangea capable of flowering and I could start another one to match it in 2018. Alas, after slaving away all summer even the stronger of the two never made it. The third picture is the root system of the second casualty :( needless to say, all of my 4 rose bushes and 20 other plants survived my city balcony just fine...maybe they are “country folk”. Guess I won’t buy hydrangeas from Burpees again.

Rated 5 out of 5 by from Looks great! These arrived right on time and in great condition. They've been in the ground for about a month now and are doing beautifully - I'm looking forward to seeing how they grow next spring.

Rated 4 out of 5 by from Grows fast The incrediball hydrangea is incredibly tiny when you first get it in the mail. I planted it in the spring after danger of frost and watered regularly. It does take some weeks for the roots to establish and during that time it does not get bigger. However, after those weeks it did start to grow. It is now mid-July and it is about two feet tall and wide. There are no blooms yet. I wanted to write this review to give other customers an idea of what to expect the first year in terms of growth rate.

Rated 5 out of 5 by from The Loveliest Hydrangea! I bought this two years ago. Yes it was very small when received. But I did get a few branches grow to about 3 feet with blooms the first year. And now, the second year, it has about 15 branches and is about 4 feet tall. The blossoms are plentiful and beautiful....reminds me of lace. I am moving soon and next year hope to order this plant for my new home.

Rated 3 out of 5 by from Still waiting This is the second season I've had these hydrangeas and I there are no blooms this year. They're just beginning to gain some height. How many years before a young hydrangea blooms? I planted a row of them along the fence line and I'm hoping my patience pays off and that they eventually look like the product photos. Fingers are crossed. If there are blooms next year I may add stars to this rating.

Rated 5 out of 5 by from Patiences pays Reading the reviews, I agree that the plant arrived very small. However, it has been three years since fall planting. The first year, it was small, maybe three branches, then the second year it grew more and bloomed amazingly large blooms--I think maybe 8 or 9 that stayed all season. This year, it is a full bush size and I am eagerly awaiting to see how many blooms there will be. I will be purchasing two's worth the wait. The flowers turn from light lime green to white to yellow/cream then dry. Don't prune it as it will continue to grow on what seems like a dead branch during early spring.

Rated 1 out of 5 by from DON'T BOTHER BUYING i have had nothing but great success with seeds from burpee, so i figured ordering live plants would be amazing as well. wrong. i have seen better hydrangeas at the grocery store. my plant arrived as a wilted stick with two droopy leaves. it also had no identification stick in the pot so i am still unsure if it is even the correct product that i was sent. i am sure that it will not survive for long when transplanted outside, and if it does it will certainly not bloom. i will only purchase live plants in person from now on.
