Timing is Everything: Reading the Signs

Timing is everything when it comes to harvesting, but knowing the right time is not easy, particularly as every crop is different. This is why you need to observe natural indicators, such as foliage yellowing and toppling, which signal maturity in bulb crops. You can also follow guidance from The Royal Horticultural Society (RHS), which advises that late summer is the best time to harvest onions in the UK.

Seasonal Calendar: When UK Gardeners Should Harvest

Following on from this, you should also consider a seasonal calendar. Generally, those planted in autumn set in early summer, while spring sets from later summer into early autumn. Many UK gardeners plant onion sets in spring (March or April), which typically yield bulbs by late summer, ideal timing for an early season harvest. Here are a few time frames for vegetable harvesting:

Leek: Harvest August-May
Lettuce: Harvest May-October
Parsnip: Harvest September-April
Pea: Harvest June-July

Harvest Techniques: Careful Lifting & Curing

Knowing when to harvest each crop is key, but you should not overlook the importance of using the right techniques. You need to use safe techniques that will protect the crop and how to cure properly. Do not just pull bulbs from the soil, as this can cause damage to the bulb and neck. Instead, you should use a gardening fork to loosen the soil around the plant and lift it out carefully. It is then a case of spreading the bulbs out in a single layer in the sun or a dry shed for two to three weeks until the skins are papery and the necks fully dry.

Storage Solutions: From Net Bags to Braids

Storage is another key consideration to prevent spoilage. Once cured, bulbs need to be stored in a cool, dry and well-ventilated space. Net bags, slotted trays and traditional braids are all good options that allow for airflow to prevent onions rotting. Additionally, be sure to remove any damaged or soft bulbs and check regularly to see if any are spoiling.

The advice in this post is helpful for any UK gardener looking to master the art of harvesting for happier and healthier onion crops. It is not always easy to know when the right time to harvest is, particularly as every crop is different. By knowing how to read the natural indicators, observing a seasonal calendar, understanding safe harvesting techniques and utilising the best storage solutions, you can improve the quality of your crop yields.
