Thinning

Thinning is removing surplus plants.
When you sow in seed holes, you put in four or five seeds. They grow together.
There are too many of them and some must be taken out.
Then the plants that are left can grow better.
As a rule the two best plants in each seed hole are left.
Thinning should be done when the plants have a few leaves, but before they are too big.
In pulling out the surplus plants, the soil is disturbed.
So it must be pressed down again round the plants that are left.
The first weeding and thinning are done at the same time.
