An Autumn Guide to Harvesting Your Crops 

As the summer comes to a close, gardens across the country are shifting towards harvesting. After months of tending to your vegetable patch, it's now the time to prepare your crops for storage through the colder months and reap the rewards of your hard work. Harvesting your crops correctly at the right time makes all the difference to flavour and longevity. In this article, we'll help you recognise when to harvest, how to lift and cure your bulbs, and the best ways to store them for the winter ahead.

Recognising Harvest Time as Autumn Nears

The late summer to early autumn period is a key window for harvesting many bulb crops like onions and garlic. There are important signs to look out for that indicate they're ready to be plucked. Yellowing or browning foliage as the leaves begin to turn is often the most obvious sign a plant has completed its growth cycle. 

If you notice the tops leaning over, it's a signal that the bulbs have matured and are no longer redirecting energy to their leaves. Similarly, if the neck of the bulb is softening, the onions are ready to lift. When you notice these changes, resist the urge to leave crops in the ground too long. Wet autumn weather can quickly lead to rot or disease.

Seasonal Calendar – When to Harvest in the UK

While crop growth can vary depending on the weather and soil conditions, there are general rules you can follow. If you planted onion sets in March or April, they are usually ready to harvest from late August through September.

Crops planted the previous autumn are typically harvested earlier, in early to mid-summer, meaning many gardeners will already have lifted these by the time September arrives. Those interested in growing bulbs in future seasons should look for quality onion sets that suit both spring and autumn planting schedules. Planning ahead can ensure you have a steady harvest year.

Harvest Techniques – Gentle Lifting & Proper Curing 

Once your crops are ready, the technique you use to harvest them can make or break their storage potential, so handle them with care. Use your garden fork to slowly loosen the soil and lift bulbs from underneath gently. Avoid tugging on the tops or stabbing the bulbs, as bruising can lead to quicker spoilage.

After lifting, bulbs need curing to ensure they store well. Place them in a warm, dry, and well-ventilated area. On sunny days, you can spread them outside on a rack or tray; in wetter weather, a shed, garage, or greenhouse is ideal. Allow them to dry until the tops are crisp and rustle when touched. Curing not only reduces moisture, lowering the risk of rot, but also enhances the flavour of the crops.

Keeping Crops Fresh Through Autumn and Beyond

Once you've cured your bulbs, store them in net bags or wooden trays. You can also give the traditional method of braiding garlic and onions a go. Inspect stored bulbs in cupboards or pantries every couple of weeks, removing any that show signs of softening or mould to stop problems spreading.

Air circulation is essential as the damp weather sets in. By taking these steps, you'll be more likely to enjoy your homegrown vegetables long into the winter and notice their flavour is stronger than supermarket alternatives.
