The Shelf Life of Compost

Last week I went to my local garden centre to buy some organic, peat-free compost, in preparation for a frenzy of potting activity at the weekend. I came away with four large bags. I didn’t really need four bags, two would have done. But there was a deal on, and I couldn’t bring myself to pay eight pounds for two, when I could have four for just another two pounds. Just how many times do I need to get caught before I learn the lesson that if something is being sold cheap, there’s probably a reason?

Some of the plants I’d been hoping to pot on

It looked like a good deal, but in fact, it stank. I found out just how much it stank when I opened the first bag. For a moment, I thought I must have picked up the farmyard manure by mistake, but no, it was compost all right, it had just gone off. I suspect it was last years stock; they wanted shot of it, and so they’d reduced the price. It was stored outside, and partially under cover, but it must have got wet. And festered. To the point where now, it smells of drains.

Soil is supposed to contain bacteria, but I dread to think what that foul-smelling community of microscopic delinquents might do to a young plant. Fortunately, I also bought a bag of John Innes, which was OK, so we were able to get some potting done. And I risked using some of the bad stuff, mixed with sand and vermiculite, to pot up some of the Cannas. A bit of a risk, but we’ve got more than we can use. And as they seem able to not just survive, but to thrive in our compost bin, I hope they can do the same in this rancid compost.

I don’t know what I’m going to do with the other three-and-a-half bags. Throw them in the canal, maybe? (Joke!) I could take them back, but it would cost me more than they cost in fuel and time. Plus, I don’t think I can face the conflict. And it wouldn’t get me back the time I lost at the weekend. I don’t have many free weekends (or much energy left) to work on my own garden, so to have lost one under such circumstances is quite frustrating. Work is picking up now too, and I’m having to fit it in around the rain, which is still frequent, so there’s even less time. Oh well!

Does anyone want some rancid compost?
