Right then, here we go. Preparing your beds for summer crops. Now I know what you’re thinking — “Tony, it’s not even that warm yet, why am I out here with a fork?” And honestly, that’s a fair question. But here’s the thing, and I’ve learned this the hard way over the years — if you wait until it’s actually warm enough to plant your summer stuff, you’ve already lost about three weeks. The soil needs time, man. It needs warming up, it needs feeding, it needs a bit of love before you start shoving courgette plants into it and expecting miracles. You know what I mean?

I remember a few years back, I was so excited about getting me tomatoes out that I just stuck them straight into the bed without any prep whatsoever. No compost, no forking over, nothing. Just dug a hole and in they went. And do you know what happened? Absolutely nothing happened, that’s what. They just sat there looking miserable for about three weeks like they were on a bad holiday. JB came wandering over, looked at them, looked at us, and just said “Have you tried feeding them, like?” Classic JB. He wasn’t wrong though.

Clearing Out the Old Stuff

First things first — you’ve got to clear whatever’s left from before. Now some people are dead organised and they cleared all their winter stuff ages ago. Good for them. Me? I usually find a couple of sad-looking leeks I forgot about and maybe some kale that’s gone completely to seed. No judgement here, we’ve all been there.

Pull everything out. And I mean everything. Old roots, any weeds that have been quietly taking over while you weren’t looking (sneaky little things), any bits of old mulch or straw that have gone past their best. Chuck it all on the compost heap. Well, not the weedy bits if they’ve got seeds on them — those go in the council bin unless you want a surprise weed garden later. Learned that one the hard way and all.

I’ll be honest, this is the boring bit. Nobody’s making YouTube videos about clearing old beds. It’s not glamorous. But it’s dead important. You’re basically giving your soil a fresh start, and that makes everything that comes after so much easier. Daisy usually sits and watches us do this bit, looking thoroughly unimpressed. She’s a Doberman, not a working dog, apparently.

Getting the Fork In

Right, once you’ve cleared everything, it’s time to get your fork in the ground. Now I’m not talking about double digging — life’s too short for double digging in my opinion, and anyway, there’s a whole argument about whether it actually does more harm than good by disrupting the soil structure. I’m more of a “give it a good fork over” kind of bloke. Stick your fork in, wiggle it about a bit, lift and drop. You’re not trying to turn it upside down, you’re just loosening things up so the roots can get through easily.

If your soil is heavy clay like mine — and bloody hell, some of the clay on our allotment is like trying to fork through concrete — you might want to add some grit or sharp sand as you go. Not builders’ sand, mind. Sharp sand. The horticultural stuff. Builders’ sand has got all sorts in it and can actually make clay worse. Ask us how I know. Go on. Answers on a postcard.

Now here’s a thing Ronny told us years ago that I still swear by — if you can stick your fork in and it goes in easily to about 8-10 inches, your soil is in decent nick. If you’re having to jump on the fork like you’re trying to break into something, you’ve got compaction issues and you need to spend a bit more time working it over. Ronny’s been growing on his plot for about thirty years and his soil is like chocolate cake. Mine’s getting there. Slowly.

Feed That Soil

This is where the magic happens. Well, I say magic — it’s basically just chucking a load of compost on and mixing it in. But it really does make all the difference. I use a mix of homemade compost (the stuff from last year’s heap that’s properly broken down) and some well-rotted horse manure. There’s a stables down the road from our site and they’re always happy to get rid of it. Free as well, which is mint.

Now the key word there is “well-rotted.” Fresh manure on your beds is a disaster. It’ll burn your plants, it stinks to high heaven, and it’s full of weed seeds. You want the stuff that’s been sitting in a heap for at least six months, ideally a year. It should be dark, crumbly, and not smell too bad. If it still smells like a stable, it’s not ready. Put it back and wait.

I spread about two to three inches of the good stuff over the whole bed, then fork it in gently. You don’t need to mix it all the way down — just the top six inches or so. The worms will do the rest. Speaking of worms, if you see loads of them when you’re forking, that’s a brilliant sign. Means your soil is healthy. Give yourself a pat on the back. If you don’t see many, that’s your soil telling you it needs more organic matter. Listen to it.

Warming Things Up

Here’s something a lot of people skip, and I think it makes a massive difference — warming your soil before planting. Summer crops like tomatoes, courgettes, beans, and sweetcorn all come from warmer climates originally. They don’t want cold feet. Would you? Exactly.

The easiest way to warm soil is to cover it with black plastic or dark membrane for a couple of weeks before you plant. The black absorbs the heat from the sun and transfers it down into the soil. You can get old compost bags, cut them open, and lay them flat — cheap as chips and works a treat. Or use proper weed membrane if you’ve got some lying about.

I usually put the covers down about two to three weeks before I want to plant. By the time I take them off, the soil underneath is noticeably warmer than the uncovered beds. You can actually feel the difference with your hands. The plants go in and they just crack on with it instead of sitting there shivering. It’s like preheating your oven before you put the roast in — same principle, innit?

Mind you, last year I left the black plastic on one bed for about six weeks because I forgot about it. Went to lift it off and there was a whole civilisation of slugs under there having the time of their lives. Thousands of the little blighters. JB nearly died laughing. So yeah, two to three weeks. Not six. Write it down somewhere.

Planning Your Layout

Before you do anything else, have a think about what’s going where. I know it’s tempting to just start planting wherever there’s a gap, but a bit of planning goes a long way. Think about crop rotation — you don’t want to put your tomatoes where your potatoes were, because they’re the same family and share the same diseases. Brassicas shouldn’t follow brassicas. Beans and peas are great because they fix nitrogen in the soil, so whatever goes in after them gets a free feed.

I draw a rough plan every year. And by rough, I mean really rough. It’s basically squiggles on the back of an envelope. But it helps me remember not to put the same stuff in the same place. Audrey next door keeps a proper spreadsheet going back about ten years. She’s got it colour-coded and everything. I admire that level of organisation, I really do. I just can’t be doing with it myself.

Also think about height. Put your tall stuff — sweetcorn, climbing beans, tomatoes — on the north side so they don’t shade everything else out. Low growers at the front. Seems obvious but you’d be amazed how many times I’ve ended up with a row of six-foot runner beans casting a shadow over me poor little lettuces. Every year I say I’ll get it right and every year I do something daft.

Dealing With Perennial Weeds

Now if you’ve got perennial weeds in your beds — bindweed, couch grass, mare’s tail, any of that lot — you need to deal with them NOW before you plant anything. Once your summer crops are in, it’s nearly impossible to get the weeds out without disturbing everything.

Couch grass is the bane of my life. It sends those white runners everywhere, under paths, through beds, under your shed probably. The only way to deal with it properly is to fork through the soil carefully and pull out every single piece of root you can find. And I mean every piece. If you leave even a tiny bit, it’ll regrow. It’s like something from a horror film. I spent an entire weekend once just pulling couch grass roots out of one bed. Filled three barrow loads. Three! But that bed was clean all summer afterwards, so it was worth it.

Bindweed is even worse because the roots go down to about Australia. You’ll never get it all out. Best approach there is to keep pulling the top growth off every time you see it. Eventually you weaken it enough that it gives up. Eventually. I’ve been eventually-ing my bindweed for about four years now. We’re still negotiating.

Adding Organic Mulch

Once your beds are prepped, fed, and you’ve dealt with the weeds, consider putting down a layer of organic mulch around your plants once they’re in. Not now — wait until you’ve actually planted — but have it ready. Wood chip, straw, leaf mould, even grass clippings work great.

Mulch does three brilliant things: it keeps moisture in the soil so you don’t have to water as much (and let’s be honest, hauling watering cans around in July is nobody’s idea of fun), it suppresses weeds (always a bonus), and it slowly breaks down and feeds the soil. Triple threat. I use straw mostly because there’s a farm near us that sells it dead cheap. A couple of bales lasts me all season.

Just don’t pile it right up against the stems of your plants. Leave a gap of an inch or two. Otherwise you can get rot setting in at the base, and nobody wants that. Think of it like a doughnut — mulch around the plant, not up to the plant. I think Audrey told us that one. She’s full of good advice, is Audrey.

Getting Your Timing Right

Here’s the thing about summer crops — everyone gets excited and plants too early. I’ve done it. You’ve probably done it. We’ve all stood in the garden centre in April, looking at tomato plants, thinking “yeah, it’s warm enough.” It is not warm enough. It’s never warm enough in April. Not up here anyway.

The general rule is — and this is me mantra, I say it every year — don’t plant tender stuff outside until the risk of frost has properly passed. For most of us in the UK, that’s late May at the earliest. I know it feels late. I know your neighbour Dave has had his courgettes out since April and they look fine. They don’t look fine. They’re struggling. Dave’s just in denial.

But here’s the good news — if you’ve prepped your beds properly using everything I’ve just told you, your plants will absolutely fly once they go in. Seriously. A well-prepped bed with warm, fed, loose soil will give you better results than planting two weeks early in cold, unprepared ground. Every single time. Plant later, sow less, get more. That’s my philosophy and I’m sticking to it.

A Quick Checklist Before You Plant

Honestly, if you can tick all of those off, you’re absolutely cooking on gas. Your beds will be in fantastic shape and your summer crops will have the best possible start. It’s not the sexiest job in gardening — nobody’s going to give you a trophy for forking over a bed — but it’s one of the most important. Get this right and everything else gets easier.

And look, don’t be too hard on yourself if your beds aren’t perfect. Mine certainly aren’t. I’ve got one bed that’s still got a random rhubarb crown in the corner that I keep meaning to move and never do. Another one has a slight lean because the wooden sides have gone a bit wonky. It’s an allotment, not Chelsea Flower Show. As long as your soil is loose, fed, and warm, your plants genuinely don’t care whether your edges are straight.

Look after yourselves. Take good care. 🌱
