Clearing an overgrown plot

Clearing a plot overgrown with brambles

Dealing with perennial weeds

Weed control fabric, which can be bought from our shed can be laid directly on to the soil surface covering an area beyond the weedy patch and the edges sliced down into the soil to prevent them from being lifted by any weed growth. They need to left in place for at least 12 months.

Using herbicides with glyphosate

Glyphosate (available in the shed) will kill them roots and all over a period of a few weeks and can be sprayed or watered on. It is not effective against Horsetail (Mare’s Tail) but they can help in its control. 
Delay spraying until the perennial weeds are in full growth. Just before flowering is the ideal time.
If you are tackling Horsetail, then damage the plant first by bashing it with a spade or trampling on it, as it will allow the herbicide to seep in. 
If the weeds are very tall it helps to flatten them before spraying.
Once the weeds have died cut them down to ground level then dig, turning the soil over, then after raking ,it is ready to plant.
If you wish you can have the soil rotavated.  (see the "Getting Your Plot Rotavated" page on the left hand menu bar)).
Where bindweed has tangled itself around a crop, tease out the leading tip or shoots and individually paint them with a glyphosate gel that you can buy from garden centres.
Ground elder and Couch grass can also be controlled with glyphosate, but regularly digging out the roots will also help in the eradication of these plants.

Dealing with brambles 
It is best to cut or strim the top growth down and then dig out the roots by hand. Always wear thick gloves. 
All weed material should be dead before it is composted or disposed of. You can kill the weeds off by starving them of sunlight (tied into a black plastic bag for some months), drowned in water inside a dark tub with a fitted lid or by drying them out in hot sunshine. The dead material can be added to your own compost heaps. Weeds should not be dumped on vacant plots or anywhere else on the allotment site where they will cause a problem for a future tenant
