How to Plant, Grow and Harvest Onions in the Garden
Gardening Tips for Planting, Growing and Harvesting Onions
Growing Onions in Your Garden
You can buy them as sets, seeds, or plants. I prefer the sets myself. They take the least time to mature and are the best at keeping away disease. Onions are an easy crop to grow, take care of, and harvest, so they a very good vegetable for first-time gardeners.
When to Plant Onion Sets
As long as the weather is frost-free, you can plant in the spring. Here in Ireland that is early March to early April. You can buy a packet of from a garden centre, store.or online. These are the ones I bought this year. They are a lot cheaper if you buy online. As you can see from the photos I got a really good crop from them too. onion sets
How To Sow Onion Sets
They prefer a sunny spot that is well-drained. If you have a small garden, your vegetables may be planted in a sunny spot, so onions can grow in a shaded area with only a few hours of sun if need be. You can plant them in long rows or in smaller batches around the garden.
- Make a trench about two inches deep.
- Give it a good watering.
- The trenches should also be twelve inches or twenty five centimeters apart.
- Place the onions five inches or ten centimeters apart along the trench.
- Cover with soil, making sure to leave the small stem on each onion exposed.
- Push down the soil firmly around each onion.
- Add another spray of water.
It may look like you have too much space around each one, but they will grow very large, so it is needed. If you plant them too close together, they will end up touching each other, and will stop growing.
Preparing the Soil
Protecting the Onion Sets
This is the time they are most vulnerable to birds. They see the green colored stems sticking up from the ground and see food. Protect them with a light cover for about a week until the plants have time to establish firm roots. I used plastic rods bent over into the ground and some polythene sheets.
- As the weeks go by water and weed when necessary.
- Do not let them go dry as this will damage the bulbs and they will split.
- The leaves will grow first tall and then thick. They prefer the cooler weather.
- Once the hotter summer weather kicks in you will then see the bulbs start to grow larger.
Onion bulbs always grow on top of the soil. They will grow wider and larger as the weeks go by and you can see them grow and mature..
When to Harvest
During this growing period, you will will have onions of different sizes. You can pick one or two as you need them in the kitchen. Pick the largest ones first. The leaves will eventually go yellow and the tops start to wither. They will fall over forming a crease so that all the energy is left to grow the bulbs even bigger.
After a few weeks from then it will be time to lift the remaining onions from the ground. You will not want to cook them all at once so here is the method that will keep them fresh for a few months more.
How to Store
How to Store your remaining crop
- Pull up all the onions that are left in the ground.
- Keep the leaves on and do not wash.
- Put them in the sun for a few hours to dry either on the grass, a sheet as I have done or on a garden table.
- Turn them over after a few hours of sun.
- When they are dry you can clean them by carefully taking off any excess soil from the bulbs.
- Put them in a dry shed or storeroom for a week making sure they do not touch each other.
- Then you can keep them fresh by storing them correctly.
- Either tying the onions together by wrapping the leaves around a thick piece of string and hanging them in your shed.
- Or you can cut off the leaves and store them in a dry box.
Both methods work well, it is just a matter of how much space you have. Your onions will stay fresh for many months and ready to use when you want them.
