The Dos and Don’ts of Composting in Your Garden

Master the Art of Composting – Reduce Waste, Enrich Soil, and Boost Your Garden’s Health!

Composting is one of the most satisfying things you can do in the garden. It’s like nature’s own recycling system – turning your kitchen scraps and garden clippings into rich, nutritious soil that your plants will absolutely love. Plus, it’s a fantastic way to cut down on waste and do your bit for the environment.

Whether you’re a composting pro or just starting out, knowing what to add, what to avoid, and how to get the best results can make all the difference. So, with Compost Week UK running from March 10–16, now is the perfect time to sharpen your composting skills and make sure you’re getting the most from your heap.

What to Add to Your Compost Heap

Think of your compost heap as a living, breathing thing – it needs the right diet to thrive! A balanced mix of greens and browns is the secret to success. Green, which are rich in nitrogen, include things like vegetable peelings, coffee grounds, tea bags, and grass clippings. Browns, meanwhile, are rich in carbon and are the dry materials like shredded paper, cardboard, dry leaves, and wood chips.

Get the balance right, about 50/50 of each, and your compost will break down beautifully. Too many greens, and it’ll be a slimy, smelly mess. Too many browns, and you’ll be waiting an eternity for it to rot down.

What To Avoid Putting in Your Compost

Not everything in your kitchen or garden belongs in the compost bin. Meat and dairy? Avoid at all costs unless you want to attract unwanted pests.

Weeds with seeds and anything diseased should also stay out – otherwise, you might find yourself growing things you never intended! Plastic, glossy paper, and chemically treated wood are a big no-no, too, as they won’t break down properly and could introduce toxins to your soil.

How to Store Your Compost Heap

You can compost in a bin, a heap, or even a fancy tumbler, depending on the space you have. A covered bin helps to retain heat and moisture, speeding up decomposition, while an open pile can work just as well but may take a little longer.

Aeration is key, so make sure to give your heap a good turn every few weeks with a fork to stop it from becoming a solid lump of sludge. And don’t tuck it away in the darkest corner of your garden – a partially shaded spot is ideal, as too much sun can dry it out too quickly.

How Long Before It’s Ready?

Ah, the waiting game! Good compost takes time, but the results are worth it. If you’re hot composting (where the heap reaches around 50–60C), you could have usable compost in as little as three months.

Here at YouGarden, every week feels like compost week, with our fantastic range!

If you’re cold composting, it might take anywhere from six months to a year. You’ll know it’s ready when it looks like rich, dark soil and smells earthy and fresh – if you can still spot bits of food or garden waste, it needs a little longer.

Common Composting Mistakes and How to Fix Them

Even the best gardeners get composting wrong sometimes:

• If your compost is wet, smelly, and not breaking down, you probably have too many greens, so add more browns like shredded paper or straw.
• If it’s dry and slow to rot, mix in more greens and a splash of water.
• Neglecting to turn the pile is another common mistake – if your compost is sitting there like an abandoned science experiment, grab a fork and get mixing!
• And remember, bigger isn’t always better – a compost pile that’s too big and compacted won’t allow air to circulate properly, slowing things down.

Composting is a fantastic way to nurture your garden, cut down on waste, and give back to the earth. Plus, there’s nothing more satisfying than using your own homemade compost to feed your plants. So, why not celebrate Compost Week UK by getting stuck in and giving your compost heap some love?
