About

Spring onions are a popular crop and very useful, possibly because they are really easy to grow. They provide a substitute for bulb onions if stocks are low as you await the new crop. 

 

Soil preparation

They like a rich well drained soil but being a useful crop to fill into gaps in the summer, they tend to get what they are given. Its a good idea to give some general purpose fertiliser a week before and rake the soil into a fine tilth before sowing them. 

 

How to Plant

Conventionally spring onions are grown in rows 6 inches apart but they can more easily be thinly scattered in a patch and either raked in or covered with half an inch of fine soil. They do not need a great depth of soil and a winter crop can be grown in the greenhouse in an ordinary seed tray filled with compost. Spring onions are ideal for container growing and even if you have a vegetable patch or an allotment, growing some salad crops by the back door where they’ll be handy is always a good idea. Successionally sow each week or two from early March for a continuous supply throughout summer. 

 

Harvesting/pruning

Spring onions grown to about 30-50cm singly or in clumps depending on which variety you use. They have a very shallow root system so can be grown in even the smallest of pots. They take about 8-12 weeks to mature. To grow quickly they like to be watered regularly and placed in a sunny position. Start snipping leaves with scissors when they are tall, green and healthy looking. Use a sharp knife to cut the spring onion just above the roots leaving about 3 cm stem in the ground. Water this and watch it regrow.
