Just imagine a veg patch which goes on giving, year after year – no need to resow or plant up each spring, and nothing to clear away in autumn.
All that’s needed is a bit of weeding, maybe some mulch and a little protection from pests – and in return you get armfuls of produce not just this year, but next year too and for many years to come.
Perennial food plants come back again and again, usually getting a little better every year. You’re probably already familiar with some – asparagus, for example, rhubarb and artichokes (both globe and Jerusalem). Fruit trees and bushes are perennial, of course, as well as many herbs including rosemary, thyme and sage.
The big, dahlia-like tubers of frost-tender yacon are sweet enough to eat raw: dig them up to overwinter somewhere frost-free and you’ll have them for years
But there’s also a wide range of lesser-known edible perennial plants which grow perfectly happily in UK gardens and provide you with a permanent supply of day-to-day greens, roots and florets to eat – no resowing required.
Grow perennial veg and you’ll never be short of something to pick. You’ll be doing your bit for the environment, too, as you use much less compost, plastic pots, water and fertiliser when you sow once and grow for years. You’re also leaving your garden soil undisturbed, which is great for locking up carbon; it also allows the complex web of interconnected life underground to thrive, so your soil is healthier and so are your plants. continue reading….
Harvesting this month: French beans, courgettes, patty pan summer squash, sweetcorn, potatoes (the last of the second earlies to eat, plus maincrops to store), apples and raspberries, plus cucumbers and tomatoes from the greenhouse, and baby-leaf salads from pots outside the back door.
Sowing this month: Autumn-sown (Japanese) onions and lots of salads, for outside (under cloches) and in pots to refill the greenhouse borders once the toms are out, including winter lettuce, mizuna, mibuna, American land cress, corn salad, chard, beetroot (for leaves), turnips (for leaves), spring onions, and round-rooted carrots.
This month I will be:
Clearing summer brassicas
Planting autumn-sown onion sets
Mulching empty beds
Saving seeds
Taking cuttings of herbs and borderline-tender plants like salvias and pelargoniums
Planting herbs and perennial vegetables
Cooking apples (and tomatoes) to freeze for winter
New perennial crops for this year
Perennial vegetables are so much more sustainable than annual as you don’t have to continually disturb the soil (so no carbon release) and they require much less input in the way of resources compared to raising seeds and using lots of water, warmth, feed and compost.
There aren’t many of them, though, and some are very unfamiliar. So one of my projects this season has been to start a perennial vegetable garden. No soil disturbance, a fraction of the inputs (feed, water, fertiliser, compost) of annual vegetables, and you lock up more carbon with permanent planting too. And a fraction of the effort of regular vegetable gardening. But the trick is to find perennial vegetables you actually want to eat: here’s what I’ve started with.
Daubenton’s (perennial) kale is growing well: it’s under a little tent of mesh to keep the butterflies off but I’ll remove that once they go away at the end of the season.
The skirret was a total failure: sowed direct in May as instructed, absolutely no seedlings. No idea if the slugs got them or if it was too dry or if they just didn’t fancy it this year. It may have been the seeds themselves so will order from a different supplier next year just in case. And I will be sowing them into pots where I can keep an eye on them.
Salsify were more successful: several good leafy rosettes now from direct sowing in May. I am leaving them to establish for a year or two before I try to pull a few roots.
American ground nut (Apios americana): I planted these odd little tubers (they are actually beans but are more like small, floury potatoes to eat) at the foot of canes by the low wall. Not all survived, but enough did for me to think this will be an interesting taste test next year!
Chinese artichokes: Easy as anything to grow – they’re related to deadnettle. I’ve got them in an old sink in the back garden: I will wait until they die back before harvesting some of the knobbly roots to try (probably next month: watch this space).
And a new addition: Turkish rocket (Bunias orientalis). It’s not the most spectacular plant, being a clump of fuzzy-felt leaves and not much else. But it is bone hardy and a useful spicy salad ingredient. And when I say spicy, I mean spicy: I had a little taste and like most things Turkish it’s ten times stronger than anything you’ve ever tasted before. I am not sure if I like it yet, but I will persevere.
New mentoring service
Well actually it’s not entirely new: I’ve been mentoring several students recently and have found it works so well I am offering it more widely.
The idea is that you have me “on tap” for advice and help about organic and sustainable methods of food growing, over email (no complicated technology to master!) and when you need it. Arrange an hour whenever it suits you and I can answer questions, give you loads of ideas and inspiration, guide you in starting up a new veg garden or help you develop an existing one. It’s entirely up to you what we talk about and it’s completely tailored to you and your garden. Book a one-off session, or a regular time each week. It’s up to you!
A lovely comment from one regular student recently: “I’m SO glad you’re there!”

This year’s tomatoes: the verdict
I haven’t a lot of room in the garden to grow dozens of different types of tomatoes but I do like to try one or two new ones each year (there are about 7,500 varieties to choose from so there’s always one you haven’t grown before)
It has not been a vintage year. I’ve had lots of tomatoes: but only one of the three I grew came up to scratch.
Ailsa Craig Good old Ailsa. What would we do without her? There are relatively few straightforward medium-sized salad toms around nowadays – we all seem to be growing fancy cherries, black tomatoes and beefsteaks instead. But sometimes all you need is a straightforward slicing tom and this one is fantastic: reliable, prolific and great flavour too.
Coeur de Bue To be honest this is my own fault as I was being a cheapskate. I grew Coeur de Boeuf a year or two ago and loved it: all the flavour and size of a beefsteak without the difficulty (or low yields). This one came as a freebie and I thought, Bue? Boeuf? Not much in it… how wrong can you be. Insipid taste, pinkish red (so hard to tell when it’s ripe) and a sort of dry texture: a pale shadow of the original. Won’t be growing again.
Reisentomate Another freebie I should have turned down. It’s an interesting idea: a tomato that grows in segments, so you can pick off a segment at a time to eat rather than having the whole tomato. But beyond the novelty value, you’ve got to ask yourself….. why? Flavour insipid, texture dry, fruits small. Just no.
Mouse attack!
Mice got into the greenhouse and ate my low-hanging tomatoes…
… and then they nobbled my newly-emerged beetroot seedlings. The giveaway that this is not slug damage is that nipped-off leaf: a slug would have eaten them down to the ground.
I have been battling the mice. You may think this would be something of an unequal fight, being as I’m several gazillion times their size but they are obviously far cleverer than me.
It started with them taking munchies out of my low-hanging tomatoes: I have never had this happen before in all my 25+ years of growing veg but it was definitely mice as they climbed on top of one fruit and left a lot of poo as a calling card. Yum #not.
Now they’re after my beetroot seedlings. I sowed them direct and they came up within days. Yet along came my whiskery friends and… no more beetroot seedlings.
I do have a feral cat but she is getting old nowadays and spends most of her time on the boiler. I am also starting to think a cat brings too much in the way of collateral damage: don’t mind the baby rabbits so much, but the robins are heartbreaking. So Sooty is to be my last cat and I will have to think of other ways to keep the little blighters off my food in future.
I could trap them, but I always prefer a live and let live policy so for now I am trying an alternative approach. Come back next month for news of its success (or not).
