Five essential elements of hydrangea

1. Planting environment:

Tips: it is recommended that there is more sunshine in autumn, winter and early spring, and it is better to avoid shade after flowering.

Hydrangea is a shade-tolerant plant, sunshine less than an hour, can also blossom, but will flower branches slender, easy to lodge. The same variety, in the environment with sufficient sunshine, has stout branches and colorful flowers. In addition, the degree of softness and hardness of hydrangea branches is also related to the variety. Some varieties, is born to love to hang, suitable for planting in the raised flower bed, let the branches naturally droop, forming a different appreciation angle.

2. Keep moist: Tips: fertile, slightly moisturizing soil and larger flowerpots

Hydrangea does not have high requirements for soil, but because hydrangea is luxuriant and requires a large amount of water, especially from April, water transpiration is rapid, so it is necessary to ensure that it is not dehydrated before the next watering, so the medium is slightly moisturized, or the flowerpot is a little bigger. Generally speaking, a 1-gallon pot can be used for half a year from the cutting planting; after that, at least 5-7 gallon flowerpots are needed. If the flowerpot is small, it is recommended to control the plant type when pruning. When the temperature is high, it is recommended to water twice a day to avoid watering the flowers. Sunburn can easily be caused by sun exposure when the flowers and leaves are wet.

Post-flowering pruning: Tips:8 pruning before the end of the month to avoid late pruning affecting flowering

Most hydrangeas are old branches and must be pruned before the end of August, so that the new buds differentiate in autumn and winter before they can blossom in the second year. When pruning, pay attention to cut off the residual flowers, cut off the aging branches, and cut the branches according to the need to control the plant type. If the planting space is large enough, leave more branches. Endless summer series and tapered hydrangea are new branch blooming varieties, so you can be ruthless when pruning.

4. Key points of fertilization: Tips: often apply liquid fertilizer, topdressing once in autumn and winter respectively

Hydrangea has a great demand for fertilizer, but there is a great deal of research on fertilization. Because flower buds differentiate in autumn and winter, they are generally fertilized for the first time in October, mainly with compound fertilizer (also called long-acting fertilizer, such as Aolu, Merlot, magic fertilizer, etc.). The second fertilization is around January, mainly organic manure (such as fermented cow manure, chicken manure, etc., raw fertilizer is not recommended). Before and after sprouting in March, liquid fertilizer is applied every 1-2 weeks, and it is recommended to use flowering fertilizer (liquid fertilizer with high content of phosphorus and potassium fertilizer).

Change color: Tips: flower color is affected by soil pH, variety, sunshine and temperature.

Generally speaking, the soil is slightly acidic open blue, alkaline open red, neutral open chaotic color, you can adjust the acidity and alkalinity of the soil as needed, so that hydrangea open from their favorite color. However, color blending needs to be carried out in advance, and it is the most effective during flower bud differentiation in winter. Toners are varied and easy to buy. However, color blending is not the only effective. It is common to open blue and pink at the same time in the same flower bed. In addition, from the beginning of the hydrangea to the middle and later stages, the color of each stage will change, even if you do not adjust the color, you can also appreciate its different tones.
