Many flower lovers in the park, botanical garden and other people's yard to see a large piece of hydrangea flowers, will be attracted by its appearance, and so they also bought hydrangeas, will find that in addition to flowering is very good-
Hydrangea branches and flowers are easy to wilt, hunch, but also easy to infect with diseases, leaf spots (powdery mildew, black spots, anthrax) and other situations, in the balcony maintenance is easy to infect red spiders, is a common insect pest of indoor plants, pay attention to early prevention.
1. Purchase attention
If you like to raise hydrangeas, you can also choose your own varieties, if it is in these places, it is recommended to raise such a more heat-resistant variety as Endless Summer.

If you buy it in a flower market flower shop, you can also see the actual product, as long as you carefully check the leaves (including the back of the leaves) for diseases and pests, you can basically see whether the whole plant is healthy.
If it is a potted hydrangea purchased online, it is recommended to look at the seedling plot, of course, you must also choose some businesses with good reputation, good reputation, and good logistics evaluation. When buying, do not patronize and look at those good pictures, the focus is on the seedling plot of the plant, that is, what kind of state the plant is in when it is shipped, even if each plant will be slightly different in form, but the overall state is similar.
If you buy hydrangeas now, its blooming period has arrived, at this time you can buy some hydrangeas with flower buds, no confidence in the maintenance of flower friends, try to buy more than 1 to 2 gallons, do not look at how many annual seedlings, buy hydrangeas, not to say that the older the better, we buy hydrangeas or to see the overall crown width, too old plant activity is not so high, although the hydrangea is a new old branch flowering, but as long as there are one or two annual branches is enough.
2. How to deal with it when I just arrived?
If you are an online shopping potted hydrangea, when you first arrive, the plant state is generally not very good, the leaves, flowers are prone to fall off, the specific performance is, such as young stems and young leaves hanging low, this is the normal water loss, timely watering it, placed in a ventilated and transparent place, basically can be quickly restored.

The first watering is particularly important, must be completely watered, you can use clear water many times to slowly water in the pot soil, do not see the water flow out will not water.
At this time, the safest way to water is to screw the pot, that is, to prepare a bucket of water to soak the potted plant in it (the water level crosses the surface of the potting soil), we will see bubbles on the surface, and when it does not bubble up, the soil is completely saturated with water. Of course, if you buy potted hydrangeas, the soil is still relatively wet, and the state of the plants is still very good, then don't rush to water at this time.
It can be sprinkled in the potting soil in advance with systemic insecticides and fungicides, such as furazine (small white medicine) and small powder drugs (thiofuranamide), which are granular, and can be slowly decomposed and absorbed by plants in the sprinkled soil, so that plants can produce disease and pest resistance, and pets and children at home can use this method.
3. Do you want to change the pot?
Just bought potted hydrangeas, do not rush to change pots, do not rush to bask in the sun, in the cool season, the temperature is below 28 degrees, you can try to bask in the sun, and so the temperature gradually rises, when the light is too strong, it needs proper shade, when the light is too strong, its buds and leaves will have sunburn, just move to the semi-shade can be alleviated, but the sunburned part can not be recovered.
4, give more sunshine
Some friends of the hydrangea has not flowered, and has not been very long, it is likely to be a lack of light, many people on the Internet to see hydrangea is more shade-tolerant plants, but it does not like excessive shade of the environment, it needs more sunlight to flower, raising hydrangeas is to ensure that in the case of not being sunburned, let it as much as possible.
Above is the first love
Some friends' hydrangea petals and leaves are easily curled and peeled off, most likely because the watering is not thorough, or the light is too strong. Potted hydrangeas, if raised in a place with more sunlight, the environment is well ventilated, and when the weather is good, it is basically necessary to water two or three times a day to ensure its needs.
There are some friends of the hydrangea flowers bloom very well, but the plant has a low hanging situation, its branches grow relatively slender, and the flowers bloom particularly large, which is also easy to lead to top-heavy, its branches are also easy to hang down, in this case you can use the gardening wire, directly in the gardening wire arrangement pot, the branches of the hydrangea flowers tied to the garden wire on the line.
5. Water diligently
Hydrangea itself is more like water, in the case of a better environment, water dispersion is particularly fast, and during flowering, hydrangeas on the need for nutrients will be greatly increased, after all, there are so many buds, the absorption capacity of water is also particularly strong, and it is still a typical large-leaf plant, the demand for water is more.
And some flower friends' potted hydrangea soil has not been able to dry, either the environment lacks light, the ventilation is too poor, or the pot soil is not breathable, not drained, you must first improve the pot and soil (change pots), otherwise it is not good to raise hydrangeas.

We can't let the potted hydrangeas have been soaked in water, if the bottom tray of the pot has been filled with water is not OK, not that it likes water on the pot, so that its potting soil continues to be wet is not good, which will lead to the rot of the bottom, to the potted hydrangea watering to let the potting soil dry and wet cycle, the potting soil is completely dry when the watering is thorough, so as to ensure that it quickly grows new roots and new shoots.
Whether it is hydrangeas, or other plants, there is a characteristic, that is, when the soil has been wet, they do not love to grow roots, and the soil is slightly dry, the plant will have a sense of crisis, it is easy to grow roots, this is the importance of the dry and wet cycle of potting soil.
6. Fertilize frequently
There are also some friends of the hydrangea has been long leaves do not flower, in addition to the lack of light, there may be frequent watering, may also be too much fertilizer nitrogen fertilizer, such as urea or flowers more than 10, etc., maintenance of hydrangeas also need to regularly supplement some phosphorus and potassium fertilizers and acid fertilizers.
Hydrangea itself is like slightly acidic soil, regular supplementation of some ferrous sulfate can improve the acidity and alkali of the soil, in addition, pay attention to regular supplementation of flowers more than two such flowering fertilizer, to ensure that its flowers can open normally, generally one or two weeks to give once is enough, and so all the flowers bloom out, or the flowers are about to bloom, this time temporarily stop fertilizing.
After all, hydrangeas are flowering plants, the demand for water and nutrients is very large, we must pay attention to thin fertilizer application, and pay attention not to use too strong fertilizer when fertilizing. For example, just bought back the potted plant, hydrangea with a lot of flower buds, this time is actually also the need for nutrients, but can not immediately give too thick fertilizer, if the state is better, after 3 to 5 days can be fertilized, you can spray it every 7 to 10 days, but the concentration is lower than usual, such as doubling when mixing water, and so these flowers are in a better state, you can restore normal concentration fertilization.
After the hydrangeas are finished, the residual flowers can be pruned, two more leaves can be cut, the cut branches can be used for cuttings, and the hydrangeas can be properly pruned, which can keep it in good shape, and can also promote the growth of new branches.
