Dismantling the broken greenhouse...after we find it

When we took on our allotment 22, there was a smashed greenhouse at one end, near the entrance. We made a brief attempt to clear it last year but we had so many other tasks to do that this one kind of fell by the wayside. We finally set aside a whole day to work on this area last week and managed to not only dismantle the metal frame and clear up lots of smashed glass, but also unearth a pretty sturdy looking brick base.

The marestail (OBVIOUSLY) had taken over the whole area, along with long grasses, brambles and bindweed. For want of a more refined technique, we simply hacked away at the weeds with a pair of garden shears. This at least allowed us to see bits of the greenhouse frame poking out from the greenery. We worked section by section, trying to take apart the frame as we came across new parts. The metal was pretty twisted in places and a lot of the bolts and screws were no longer usable so we ended up pulling most of it apart rather than using any tools.

There's a greenhouse under there somewhere...

It took most of the day to clear the greenhouse and part of the surrounding area but it's made a huge difference. Now when you're working on the plot, you can look up and see other plots and people walking by rather than just a 5-foot high wall of marestail!

We have a greenhouse base!

We've managed to get up most of the glass and that will be heading to the tip. As for the frame, we're going to keep hold of that until there's another scrap metal collection on the site. 

This weekend will involve clearing more of the land around allotment 22 and possibly even laying our first section of path! We're planning on using heavy duty weed membrane with woodchip on top. Handily, the council have just dumped a pile of woodchip inside the site entrance so we're hoping there's still lots there tomorrow. The problem with working full-time when half of the other plotholders are retired is that they're there every day in the week so we miss out on things like free woodchip as it's all gone by the time we get there!

Weed Suppressant

As our plot was so overgrown when we took it on, we decided to start by clearing the worst of the weeds and then laying down some kind of weed suppressant. We researched a few different options and spoke to other plotholders and friends who were experienced gardeners. While a lot of people seemed to favour old carpet in the past, this wasn't an option as the use of carpet is banned on our allotment. The reason for this is that chemicals can seep into the soil. We didn't have ready access to carpet anyway, so this wasn't too much os a disappointment! Cardboard was another option, and we still intend to lay down some very heavy cardboard in some parts of our plot, possibly the more heavily overgrown sections that we won't get to just yet.

We also considered black plastic sheeting. There was already some of this on our plot, albeit very ripped and cracked. While this is a popular option as it keeps light AND water off the ground, thereby killing weeds more quickly, we were put off by the fact that the ground would be very dry and hard to work. We always planned to uncover small sections of ground at a time, and map out and dig over our beds one by one.

As the vast majority of the central part of our plot was taken over by mare's tail, which we'd be breaking off at the ground, and various grasses, we opted for weed membrane, which we hoped would be able to cope with finishing off the grass while preventing the mare's tail from popping up again. We read lots of reviews online and checked out forums to find which one would suit our needs. We knew we'd be traipsing back and forth over it, and that it needed to be heavy duty. We also wanted something that would let water in but was thick enough to effectively block light.

We checked out a few fabrics in shops, but lots of them seemed pretty flimsy and let a lot of light through.

 Eventually, we decided on this Yuzet Heavy Duty Weed Control Fabric from Amazon. It gets great reviews, and seemed reasonably priced for a heavy duty weed membrane. It also came in 50m rolls, which was great as we knew we'd need a lot! While it's only really been a couple of months since we laid the first of our weed control fabric, we're really impressed so far. It's withstood all kinds of weather so far, and has remained firmly in place. There are absolutely no signs of wear and tear yet, except at the odd edge where we've snagged it while cutting, or have had to pull pegs out to move them.

As you can see from the photo, it's got a bit of a sheen to it, and is a little more plasticky than lots of fabrics. I was concerned it might tear easily because of the texture, but this honestly hasn't been a problem. The guidelines down the length of the fabric will be helpful when we come to lay paths in future and the fabric is really easy to cut with regular scissors.

We started off holding it down with bricks, but this wasn't ideal as they're easy to trip over and kick out of position. We got these Yuzet 6" Weed Control Fabric Pegs, also from Amazon, and they've been great to use. We push them in as far as we can with our hands, then stand on them firmly to push them right into the ground. It's a lot easier when it's rained recently, that's for sure! The only problems we've had are when the pegs have hit stone or pebbles - all too common on our plot, sadly - and we have to pull them out to re-position them. When you do this, the hooks on the pegs can catch on the weed control fabric and fray it a little but it's not too much of an inconvenience.

All in all, we're impressed with this product so far and will certainly be buying it again when we run out of our current supplies.

The Dreaded Mare's Tail

I'd never heard of mare's tail - or marestail, or horsetail, or Equisetum arvense to give it is proper name - before we took on our allotment. When we first viewed allotment 22, most of the weeds and grass had very recently been cut back by the council. Although the council have a policy to not get involved in the upkeep on allotments these days due to a lack of funds, apparently our plot was so bad that they made an exception.

When we viewed our plot, it was neglected and overgrown, but I didn't notice any mare's tail. When we returned two weeks later, it was full of those strange cone-like stems. We had no idea what they were, but a friendly fellow plot holder told us. After plenty of online research, we established mare's tail is almost impossible to remove, but that it is possible to weaken it dramatically.

This was taken before the mare's tail actually got too bad :-/

Most of the online resources I've used state that the fir tree-like mare's tail plants can reach "up to 2 feet in height". All I can say is, I wish ours was only 2 feet tall! In certain spots - usually in and around bushes and brambles - ours regularly reaches heights of 5-6 feet. Yep, it's as tall as we are. In fact, it's a lot taller than us in places but we haven't got round to tackling the more towering stems yet!

How to remove mare's tail

The one good thing about mare's tail is that it's easy to remove the shoots and fertile fir tree plants by snapping them off at the ground. We must have filled about 10 huge cement sacks (the kind you could fit a small car in) in just a couple of weeks by doing this, and there is still a lot more to go. I think we've been to the council tip more times in the last few weeks than we have in our entire lives. It's very satisfying to get rid of them, though, even though I know they'll return!

Our hope is that once our plot is cultivated, we can try and stay on top of the mare's tail as much as possible, removing shoots as soon as they appear. Considering our plot has been neglected for so long, and due to the time of year we took it on, it's safe to say we shouldn't experience anything like the same level of problem with mare's tail again.

Although there is a fair bit of mare's tail on the rest of the site, it's nowhere near as bad as on our plot. Our neighbours have the odd stem sprouting up among their crops, but the majority of sites don't have any signs of it.

If you're determined to eliminate mare's tail, horse tail, Equisetum arvense, call it what you will, this site has some great tips and case studies. We're sticking to the snapping-off-and-hopefully-weakening technique for now though!
