Algae in the Greenhouse – Diary of a Rocket Gardener

It’s not going to be a long post this week, folks. That’s partly because I’ve chosen quite a quick topic, and partly because I haven’t been spending a huge amount of time in the veg patch because it has been so cold!

With the slightly milder weather this weekend I did dare to venture into the garden for a little while, and one thing I was pondering was the appearance of algae (or it could be a funny kind of moss) on the surface of the soil in my greenhouse. There is also a little on one of the raised beds outside.

I think what this comes down to is the damp. The soil just hasn’t really dried out at all for months now – even in the greenhouse (it’s a very makeshift greenhouse, and water comes in from the roof whenever it rains, so it stays wet all winter!)

I’m not going to worry about it too much, but I did want to touch on it this week in case others have found algae in their plots and were wondering whether to tackle it or not. My own approach is to leave it as is for now, and then when it comes to spring planting I will scrape off the top level of algae and freshen up with some new compost. During the drier spring and summer months it should be fine, and for now the algae is not competing too much with the veg plants, so nothing to worry about!
