Growing Onions from Sets

The easiest way to grow Onions is to start with “Sets” these are simply small immature onions.

Sets are produced  by sowing onion seed thickly normally in the Summer the plants are allowed to grow just until they start forming bulbs, these immature bulbs lifted and cured like regular onions.

A lot of onion sets are “heat treated ” this means they are subjected to higher temperatures which kills the flower embryo and so prevents the onions “bolting” or running to seed before forming the onion bulb.

Heat Preparation also extends the growth period which means that greater yields can be achieved.

You can also plant Shallots and onions in the Autumn

A dressing of calcified seaweed at planting helps with PH as onions prefer a PH around 6.5 Autumn planting is not suitable for heavy soils prone to waterlogging as the crop is more likely to succumb to disease

Over-wintered onions and shallots greatly benefit from an application of 35g per sq m (1oz per sq yd) of nitrogen-rich fertiliser such as sulphate of ammonia in late Febuary/March. This not only enhances growth but can also help suppress premature flowering. Alternatively, use dry poultry manure pellets
