Garden Hydrangea Care

Hydrangeas are one of the most impactful flowering plants you can select for your garden.  They can be a bit difficult to manage without knowing a bit more about their preferred care protocol.

If you plant hydrangeas, plant them by digging a planting hole about two metres wide with a root ball. Keep the depth of the hole in line with the size of the root ball so that your plant sits flat and high above the surrounding soil. By creating a slight mound of soil, you help to increase the drainage at the base of the plant. (6)

You can dig a small trench around your hydrangea plant. Make a scratch in the bark where the branch touches the trench floor. Bend the branch into the trench until it touches the ground in the middle of the branch, from where it extends out of the trench. Fill the ditch and place a paving stone or brick or stone on it. (6)

Hydrangea prefer a loamy mixture of sand, mud, some clay and moist soil, so check it first to make sure it is not too dry or soaked. It’s fine to cheat and buy a shrub from your local garden centre or try to grow your hydrangea from seeds when seeds are hard to come by. When placing hydrants in the ground, cover the ground with water. (5)

The introduction of a lot of organic matter and a useful slow-releasing fertilizer into the soil gives your hydrangea a strong start. Most varieties thrive in full sun or partial shade, so they should be planted in moist, rich soil. Water every week or longer when the weather is hot and dry. If the soil is too wet, the roots rot and the plant dies. Those who plant their hydrangea in the summer need much more water at the beginning to build up a root system. (2)

Bigleaf and smooth hydrangeas require more water, but all varieties benefit from even moisture. It is best to water in the morning to prepare the hydrants for the heat of the day and to avoid diseases. The leaves wither when the soil is too dry, and flowering can be hindered by lack of water. Often use a water hose to keep the moisture in the flowers and leaves. (4)

Water at a rate of 1 inch per week during the growing season. In the first one to two years after planting due to the drought, care must be taken to ensure that the hydrangeas receive sufficient water. It is better to water three times a week and spread the water flat. (4)

Hydrangeas enjoy a rich soil with organic material and require a well-drained location. When exposed to the hot afternoon sun without sufficient moisture, the leaves wither and hang. They prefer full sun in semi-shady locations and can handle hot, full sunshine as long as the soil is moist. They have large leaves and their leaves release a lot of moisture. (0)

Most hydrangeas are hardy in USDA cultivation zones 5-9. They can adapt to a wide range of growth conditions. As long as they are planted in well drained soil with a lot of organic matter, they grow well. (1)

Hydrangeas generally tolerate a wide range of soil species. Hydrangeas thrive in full sun and do not need additional water even on hot summer days. They do best in the partial shade of tall deciduous trees, so they should get some morning sun, but the shade should be heated up in the afternoon. Too much shade can reduce the yield of a perennial bloom. (1)

One of the advantages of growing hydrangeas is that they can change their flower colour. To determine the variety, the flower color can be changed by the amount of aluminum in the soil and the pH value of the soil. The pH value of the soil determines the aluminium available for the plant. (1) This is due to soil chemistry and the pH value can influence the flower colour of thick-leaved mountain species such as H. macrophylla and H. serrata. Flowers can be blue in acidic soils and purple or pink in alkaline soils. (0)

Blue hydrangeas: Blue hydrangeas from the thick leaf family are blue because of the soil in which they grow. You can buy blue hydrangeas to see them blooming in different colours all year round. Pink hydrangeas: Pink hydrangeas range from hot pink to blush and are found in various varieties. Endless summer hydrangea: Discovered in the 1980s, this plant has the ability to withstand the coldest winters in Zone 4. (6)

When hydrangeas are transplanted, they should be put to rest in autumn and winter. Make sure to dig out the entire root ball and replant it. The flowers still produce new growth when they are pruned back at the end of their bloom. (3)

This is one of the easiest hydrangeas to cut. Oak-leaved hydrageas bloom like new wood and produce large flowers when pruned from the ground in late winter. When cutting oak leaf thyacinths, you want to keep them in shape by cutting off dead stems and soil in late winter or early spring. (2)

The pruning of hydrangeas in late winter prevents them from overgrowing and promotes more new growth with more flower buds and larger flowers. Cut last year’s flowers and shoots back about 1 / 2 inch and cut the shoots that cannot attach or pull away from their support. They can remove dead flowers if they become unattractive and clean up the overall shape of the plant. (2)

It will help to revive your hydrangeas and increase their durability. The flowering period is from midsummer to autumn. He recommends planting flowers in areas that get five to six hours of morning sun, followed by spotted or blotchy shade. If you live in a warmer region, plant them in the morning sun for two to three hours and in partial shade in the afternoon. You will want to plant early in the summer to avoid this on hot, bright days. (5)

If you are lucky enough to have a garden hydrangea, it is easy to bring it into the house for beautiful arrangements. No matter what you choose, your hydroponics should be stored in a healthy state, with bright green leaves and lush flowers. If you choose a healthy bouquet, it should last at least two weeks. (5)

Grow H. macrophylla and H. serrata varieties in zones 4 and 5 and do not cut them back before flowering. Remove dead stems in spring. Panicles of H. paniculata and smooth H. arbintendoens hydrangeas can be pruned before flower buds form. (4)

Remember that the ingestion of hydrangea leaves or flower buds can be toxic to cats, dogs, horses and humans.
