Some key techniques of planting Hydrangea

It is necessary to plant Hydrangea in proper position This kind of plant needs sunshine, but too much will prevent it from blooming When planting Hydrangea, soil type is very important to determine the color of some species In addition, proper pruning is also important to promote flower growth It is very important for plant health to plant Hydrangea in a proper place in the garden or courtyard The ideal amount of sunshine per day in the planting site depends on the geographical location For example, growing Hydrangea in the cooler climate in the north can provide more sunshine than in the south In the south, Hydrangea can thrive and bloom in about 3 hours of sunshine (preferably in the morning) every day When planting Hydrangea, too much shade will inhibit flowering Therefore, when choosing a location, it is best to find a place with partial shade The variety of Hydrangea also determines how much sunshine or shade is needed For example, compared with the more sun resistant Hydrangea spicata, the hydrangea acorn leaf is more suitable for planting in some shade areas Choosing soil is also one of the skills of planting hydrangea Acid soils usually cause blue flowers, while alkaline soils support red or pink flowers Depending on the soil conditions, the color of Hydrangea grown in a garden or garden can vary If you bring back a blue flowering plant, you can keep the flower color by adding aluminum sulfate to the soil Aluminum sulfate can also turn red flowers into blue Adding superphosphate or lime to the soil can turn blue flowers into red or pink To effectively change the color of flowers, gardeners must add soil amendment before Hydrangea flowers Pruning Hydrangea is very important for healthy growth Gardeners need to know when to prune and how much to prune to be good for flowering and plant health Removing dead heads can promote the opening of new flowers Some hydrangeas should be pruned at the end of winter, others in early summer The flowering of Hydrangea macrophylla originates from the old growth, which means that cutting branches in winter or autumn will cut off the flower buds, and it will not bloom in the spring and summer of next year Gardeners should avoid pruning these varieties after August because new growth will be killed by early frost On the other hand, other varieties, such as Hydrangea spicata, are newly growing and blooming, and should not be pruned in summer, or the flower buds will be cut off.
