The best choice is clay basin, a little deeper, according to the size of the plant, width and height above 35 cm.
Put the hard plastic foam on the bottom of the basin to increase the air permeability of the basin.
Prepare sulfur powder or methyltobuzin powder, pay more attention to the root powder and Luheng No. 1.
In spring and summer, where there is good illumination and ventilation, it is better to have dew weather.
In addition, before planting, we need to check the peony plant, check whether there are black patches, white mildew spots, broken roots and so on at the root. If we don't find any problems, we can plant normally.
First of all, clean the peony plant, put the root of Peony under the tap, and rinse the root. Then soak in disinfectant and rooting powder for 30 minutes. Because the root system of peony is long, it is better to use barreled water to let the root stretch and bubble. The next step is to prune the roots. Cut all the old roots and keep the new roots and thin heels. Cut off the long roots according to the size of the flowerpot.
Put the peony in the basin, put it in the right position, add coarse sand and then add fine sand, shake the flowerpot, so that there is no gap between the root system and the flowerpot.
Then put some coarse sand, or bark, pine needles on the surface of the soil, so as to avoid soil hardening during long-term watering or fertilization. Then pour water and put it in a cool place for curing.
