Hydrangeas have a speciality of changing colour from blue to pink and then from pink to blue and sometimes colors can be vibrant pinks, frosty whites, and lavender under certain circumstances. The colour changing ability of this flower is due to the change in soil pH.The colors are as follow:
• If pH level is less than 5.5, then colour is blue
• If pH level is greater than 5.5, then the colour is pink.
• Interestingly, white flowers do not show any effect on the pH level of the soil.
Hydrangeas are one of the flowers which are used for group plantings in gardens.While planting these, take proper care that the blooms and stems of the plant do not get in touch with that of strong winds and sun.These require proper shade and protection from the winds.Proper care about the drainage of the plant should also be there.
Various stages involved in the growth and plantation of hydrangeas:
1. Selection of the site and soil preparation
Check out properly for the area you want for planting hydrangeas. It should be such that there will be proper sunlight in the morning and proper shade in the afternoon.It cannot handle too much of sunlight.Next step is the selection of the soil which can be determined by asking soil test kit from any of the local nurseries. Different types of soil which are found out by the test kit are sand, silt, clay, and loam. After knowing the type of soil, the preparation of soil becomes very easy.The best soil for these plants is considered to be loam.
After testing the soil, start planting plants and make sure that each plant is planted at a distance of 4 to 9 feet so that they do not touch each other.After that, a hole is dug and soil is enriched with the required nutrients and organic matter.Then put the plant in a hole and then fill that hole up to half with the soil and then water it.After the whole water is drained, put the rest of the soil into it.
3. Fertilization and watering of the plant
These plants are usually planted in spring or fall season and fertilizers are used for increasing the bloom production.Phosphorus is one of the fertilizers which is effectively used for the production.If we will over fertilize the plants, then they will not produce any good effect but will affect the blooming of the plant only. Further proper drainage is necessary.
The most preferred soil for these plants will be well drained.Similarly overwatering will cause the negative effect. The amount of water required by the plants depends on the different type of soils used. For example, clay soil holds water more than that of other soils and hence will need less water.
Care of Hydrangeas
After growing hydrangeas, the most important step in the care of theplant so that proper blooming will take place.Proper care should be taken for first 1 or 2 years.Make sure that the soil does not get dry. Make a note of thing that if the soil is already rich, then do not add plenty of fertilizers to the soil.And if it is light, then it is good if the watering is done once a year.
During the fall season, plants should be covered up to the depth of 18 inches with straw, leaves and pine needles.And if possible, cover the entire plant with the cages of snow fencing.
Hence with the appropriate location, soil and moisture content, the hydrangeas will be ready with gorgeous blooms in the near future.
