Celandine, Celandine; surely not a friend of mine…

Is it my imagination, or is the Celandine particularly rampant this year?
This is a very difficult weed to deal with, mainly because of the small tubers that form under the soil at the base, and that tend to break off and lose themselves in the soil when you dig up the plants.

You can see these in the picture to the right. The RHS refers to these tubers as ‘tubercles’, which sounds a bit like a disease. And I can tell you that, faced with a patch of ground that’s covered in Celandine, it feels a bit like a disease too! You can never dig all of them out without leaving some of the tubercles behind, and if you’re not careful, by digging, you can turn a small colony into an infestation.

Mulching may well be the best organic approach to control. The RHS recommends a 10cm layer of organic material, but warns that this may not fully eradicate them. Membrane, with organic material over the top might be more effective. Although I know of at least one garden that has been mulched with heavy plastic, with gravel over the top (not my doing) where the celandine is pushing up forcibly around the edges, and at the base of the roses that were planted through the plastic.

If you’re happy to poison your soil, you could always douse the effected areas with glyphosate every spring.

The RHS encyclopaedia says Celandine is ‘good for a wild garden’. I must admit I’m a bit prejudiced against that because, with a few notable exceptions (such as Daffodils), yellow isn’t my favourite colour in the garden. But perhaps we shouldn’t get too worked up about this little plant. It’s easy to panic when you see a carpet of the stuff where you’d intended to have cultivated plants. But Celandine provides good ground cover, colour (albeit yellow) at a time when that can be in short supply, and by early summer it’s died back so as you’d never know it had been there. Maybe the easiest option is to learn to love it!

The Sleeping Garden

Skeletal Achillea

Actually gardens (like money) never sleep. They may doze, but they’ve always got one eye half open, even if most of the plants are in hibernation. The weeds rarely stop entirely. In fact I’ve just done my first full-on weeding session of the year, for one of my customers whose borders had been invaded by a fine crop of annual weeds. Did no-one tell them it’s winter? Fortunately I managed to get most of the work done before the rain really set in (but it wasn’t pleasant out there).

The other thing (or rather; things) that don’t stop for winter, are the slugs and snails. From now until the growing season really gets going is a critical time. There are plenty of slugs around, and on mild nights (and days, sometimes) they’re out and about, trying to feed. But there isn’t much for them to eat. So when your perennials, bulbs, etc. tentatively poke their heads above ground, they’re likely to be grazed off at the neck. It’s a battleground out there, and at this time of year the plants are heavily outnumbered.

A Meagre Catch

Time then, for us gardeners to deploy our special powers to even the odds. In my own garden, because I want to garden organically, I don’t use slug pellets. I have other solutions up my sleeve. In the growing season I go out at night and pick them off. Not every night – I have got a life, of sorts.  At this time of year, slug traps work well. You can pay a lot for manufactured slug traps, or you can make your own. I recycle yoghurt pots or, better still, shallow glass dishes, and cover them with scraps of stone, to keep the rain from washing the beer away.

Slug Cairn

Last year I got the pond dug, filled and planted (though I’m still working on the water feature) and it plays host to a healthy population of frogs, which eat their fare share of slugs. Although I’ve never seen them doing it. I can’t imagine them tackling a slug that’s almost as long as they are (imagine a frog getting that stuck in its throat!) but they’re invaluable for keeping down the smaller slugs. They certainly did a good job protecting the hostas around the pond in my last garden.

There are a few little joyous touches here and there amongst the barren soil and dead foliage. The Chaenomeles (Japanese quince) has already flowered well, and there are snowdrops and winter aconites. Some of the daffs aren’t that far off flowering, and nor, surprisingly, is the Ceanothus. I’d like to think spring isn’t far away, but I know there’s some very cold days to come before it arrives.
