Sowing in open beds

Sowing in nursery beds and transplanting
80. Disinfect the soil of the nursery beds. The soil should have a fine filth and be firm in depth. Leave 10 to 15 centimetres between rows.
Make a shelter and water the beds twice a day. Thin out surplus seedlings and weed.
When the seedlings have grown to a height of 15 to 20 centimetres, take them out of the nursery beds and transplant them into new beds. Leave 20 to 30 centimetres between rows and, along the rows, 10 to 15 centimetres between plants. Set the plants only 2 or 3 centimetres deep In the soil.
Pack the earth down well around each plant. Water. If any plants do not grow, replace them with seedlings you have kept in the nursery beds.
Do not earth up the onion plants when you cultivate; if you cover the bulb with earth, the bulb does not grow well.
