With a little soy sauce, the hydrangea is not only bigger than the face, but also turns blue.

Hydrangea, also known as "hydrangea", is famous for its beautiful petals. The flowers gather together to form hydrangea, which is very beautiful and has a very pleasant aroma. It is loved by flower friends.

Hydrangea flowering is spring and summer, in the flower shop to buy hydrangea or more expensive, and now many flower friends have chosen potted. A lot of flower friends say hydrangea flowers are not easy to raise flowers, I think it is not difficult, do the following points, with a good material, but also can call out the color of very fairy.

1. Purchase. We usually buy potted plants online or at local flower markets. It is best to start flowering. The diameter of the selected pot is about 15-20cm, and the pot can be changed according to the size of the plant later. The pot change is generally selected in March and April of each year.

2. Soil mixing. Flower friends remember that the general principles of soil are: loose, breathable, fertile, whether hydrangea, or clematis and other plants are applicable, different plants as long as a little adjustment of the proportion is good. Hydrangea is a woody plant that can grow for many years, so when we mix soil, we can add some materials that are resistant to decomposition.

First of all, I will choose coconut bran and peat, because the ventilation is better, but also cheap, haha, I am relatively poor, so these two or cost-effective. Only these two drainage is not very good, you can add some pearlite or volcanic rock, improve the soil permeability and drainage capacity, promote root growth; put some bone meal in the bottom of the pot as base fertilizer is ok.

Experienced flower friends will know that planting things is particularly easy to rot roots, this time need to come to a little green zeolite! Chlorite, which can prevent plant roots from rotting, can be said to be a material worth adding.

Then peat, coconut bran, perlite, green zeolite, bone meal according to the ratio of 3:3:2:0.5:0.5 can be mixed. This soil is not the most perfect, only the most suitable, we have to make some adjustments according to their actual situation oh.

And most importantly, hydrangeas come in blue and red, blue if the soil is acidic and red if the soil is alkaline. Therefore, two conditions are needed to color: acidic soil and aluminum ions.

Generally speaking, a gallon of hydrangea, aluminum sulfate plus 8g against a liter of water, irrigation once every 10 days, afraid of burning seedlings, then you can appropriately reduce the concentration, the soil is too dry when you can first water again, continuous use, until flowering. Industrial aluminum sulfate is very cheap, a few dollars a bottle can be used for several years.

Tap water in many places is alkaline, so you can choose the acid-loving organic nutrient solution that flowers know. This nutrient solution looks like "soy sauce". It is made by fermentation of sugar cane molasses. It has a slight sweetness and is rich in nitrogen, phosphorus and potassium. It is used once every 15 days for hydrangea, which not only promotes flowering, but also improves the acidity of the soil. It is a color matching essential.
