How to Make Leaf Mold

For my Masters dissertation last year I did some research into gardeners who choose to grow unusual edible crops. I settled on two species to investigate, achocha and oca. In the past I’ve written about how to grow achocha – it’s a nice, easy plant and in a temperate climate you should have no problems getting a significant yield. You may have more of a problem dealing with the glut….

As its Valentine’s Day today, and the whole world is in the mood for love, I thought I would talk about one of the most enduring and productive relationships a gardener can have. Although plants (and even gardens) may come and go, if you invest in good tools and look after them properly they will be with you throughout your gardening life.

The arrival of some ulluco (Ulluco tuberosus) tubers from Incredible Vegetables left me pondering how best to store them until it’s time to plant them out (after the risk of frost has passed, in spring). Given that I also have mashua and oca tubers kicking around the kitchen, and that everyone will soon be receiving seed potatoes (if they haven’t already), then I thought it might be nice to have a general round-up of how to store tubers for planting. A lot of the advice will be relevant to all kinds of tubers, but each species is likely to have its own quirks. If you have advice, details for new species, or queries, then leave them in the comments – I can update this post later.

It’s raining heavily today, so there’s no point even trying to go outside into the garden, but if there’s a plus point to such dreadful weather then it does – at least temporarily – make people aware of what’s under their feet. Soil tends to be forgotten until it turns into mud, or you squelch along through sodden grass, or watch priceless fertility washed down the drain. Weather like this shows us the importance of winter soil care, particularly keeping soil covered (even if all you have is weeds!) so that plant roots can hold it all together for you.

If you’re one of those people who loves scavenging for useful things, or has a pile of interesting odds and ends stashed away for future projects, then you could think about recycling them into a 5 star wildlife hotel.

Fungus gnats are tiny little black flies that love living in damp organic matter (i.e. compost). They thrive in warmer weather, so at this time of year – with all the seedlings indoors – the house is full of them.

I met the Duke of Edinburgh a few years ago. Shame I was stuck in front of a computer at the time, and not somewhere more exciting like the Chelsea Flower Show. Meeting human royalty might be a rare occurrence for most people, but you can surround yourself with royal plants and get that regal feeling every time you step into the garden. To illustrate my point, let me share with you an old joke….

When I woke up yesterday morning, it was misty. We’re approaching the middle of October, which is the usual time for the first frosts of autumn in my part of the UK. People in different areas are already reporting the arrival of the frosts on Twitter. This means it’s time for me to pop out into the garden and bring in my lemon tree (which I grew from a pip, several years ago). It has been enjoying the summer weather in the garden, but it’s only really hardy down to -10°C. I’ve nearly lost it a couple of times, and it has died right back to nothing, but somehow it always manages to come back.

If it’s the middle of winter and there’s nothing much going on in the vegetable garden, or you want some easy and ultra-fresh salad greens, or a rainy day project to help keep the kids occupied, then try growing mustard and cress!

Mould (mold) spores are everywhere, they’re inescapable, and moulds love growing in the warm, damp and humid conditions that seedlings need to thrive. If you have biodegradable pots then moulds can rapidly colonize those; but they will happily grow on the surface of compost as well. A lot of the moulds we see won’t do much damage to the seedlings, but some of them will and having mould on the windowsill isn’t much good for us either.

There might be a new chill in the air, but autumn is a beautiful time of year, when the leaves change color on the trees and the sun shines through a million little stained-glass windows. But once the leaves fall to the floor then it’s a different story. If they fall into ponds they can foul the water, on the lawn they can cause bleached patches and they make paths slippery in the winter. Gardeners everywhere spend the autumn raking up leaves to prevent these problems, but did you know that you can turn them into free soil improver for your garden, rather then sending them off with the rubbish?

Remember those heady days at school, when you were faced with choosing your subject options, or which courses – at which higher education establishments – to apply for? There were a lot of things to consider, lots of differing advice on hand, and the prospect of making decisions that would affect (you were told) the rest of your life.
