The open-field coriander planting management methods you can refer to are as follows:
First, coriander has a long germination period; it takes about 9-10 days from sowing to emergence. During the coriander germination period, if there is sudden clear weather after rain, a layer of "pot crust" is likely to form on the seedbed, seriously affecting the coriander emergence rate. Vegetable growers can water lightly once to ensure soil permeability and help emergence.
Second, when coriander grows to 4-5 cm high, thinning is needed. Vegetable growers can thin the seedlings at a spacing of 3-4 cm between plants to ensure coriander has enough growing space. The seedlings kept should be uniform in size to make management easier. While thinning, field weeds should also be removed.
Third, coriander has few diseases. Because it is grown in the open field, and now is also a period of high pest incidence, vegetable growers should focus on pest prevention. They can use 0.5% emamectin benzoate 4000-fold solution or 2.5% Caixi suspension concentrate 1000-fold solution for prevention, once every 5-7 days.
