The best mulch for vegetable gardens if you want a happy and thriving crop

Whether you are a pro-grower or a novice gardener knowing the best mulch for vegetable gardens is essential to help your crops meet their highest potential!

Whether you fancy learning how to start a small vegetable garden or simply want to boost the health of your raised beds, mulching – and mulching properly – is the key to success. Because even the very easiest vegetables to grow need a helping hand every so often.

It's an especially useful tool if you're planning to adopt a no-dig approach to your outdoor space, too, as it improves the condition of your soil and helps suppress weeds. Win-win!

'Mulching your garden beds is good practice to help replenish nutrients in the soil, improve soil structure and retain moisture,' says Morris Hankinson, director of Hopes Grove Nurseries.

Morris Hankinson is the founder and managing director of Hopes Grove Nurseries Ltd, the UK’s only specialist grower-retailer of hedging plants. He established the thriving business in 1992, shortly after graduating with a Commercial Horticulture Degree from Writtle College, Essex.

'There are many materials that can be used to mulch with and what you choose can depend on availability, cost, style and nutrients needed,' he adds.

On that note, here's our pick of the best mulch for vegetable gardens in particular...

1. Homemade compost

Learning how to hot compost isn't just a trendy new garden fad; it's also one of the easiest and quickest ways to make compost (which, incidentally, is one of the best mulches for a vegetable garden).

'Nothing much beats a good quality homemade compost,' says Morris. 'Adding a layer of well rotted compost will help to get rid of weeds naturally and provide nutrients to the soil.'

2. Autumn leaves

Autumn leaves will help you to thrive because leaf mould is widely considered to be one of the best mulches for vegetable gardens.

'Autumn is the perfect time to collect leaves, bag them up and store to make leaf mulch,' says Morris. 'Over time they will break down and can be used as a mulch to improve the soil.'

Monty Don agrees, writing via his garden blog that 'every fallen leaf is potential leafmould and leafmould which, unlike compost, takes no turning, mixing or knowledge to make, is garden gold'.

However, he adds that gardeners should 'also leave drifts and piles of leaves under hedges and trees to provide overwintering cover for hedgehogs, frogs, small mammals and insects' in their wildlife garden, too.

3. Bark and wood chips

If you're already learning how to use bark to stop weeds taking over your garden borders, you're in luck; wood chips are widely considered the best mulch for vegetable gardens among experts.

'Woodchips decompose quite quickly and enrich the soil,' says Morris, who notes that 'using wood chips is ideal for pathways and around trees'.

If you don't fancy buying wood chips from your local garden centre, the experts at the Royal Horticultural Society (RHS) say that you can make your own easily from larger trunks or branches, too.

'Instead of burning [wood], chipping or shredding it can turn this waste into a valuable mulching material,' they say.

Still, Morris notes that 'bark doesn’t decompose as fast as wood chip and therefore won’t need replenishing so often'.

4. Straw

Did you know that you can use straw as a mulch – either in your vegetable garden or over the vegetables you grow in pots, too?

'Vegetable gardens can benefit from a mulch of straw because it helps to suppress weeds and like other mulches, it helps to retain moisture,' advises Morris.

'As it breaks down, it will also help replenish the soil with organic matter.'

5. Grass clippings

There's a reason you shouldn't chuck your grass clippings away (although, remember, you should let your grass grow long this winter if you want a healthy, happy lawn).

'Grass clippings are a good choice for vegetable beds if used sparingly and as they decompose, nitrogen will be released into the soil, helping vegetables to grow,' says Morris.

What type of mulch is best for a vegetable garden?

While most tend to think of newspaper or cardboard as the ideal mulching materials, you're better off using something like homemade compost or leaf mould in your vegetable beds, as it's packed full of nutrients that will condition your soil and give your crops a much-needed boost, too.
