Current allotment area of guilt: a strawberry patch so riddled with weeds and grasses that the strawberry plants are hard to spot. I know, I know, they won't fruit and flower without some urgent space or attention, but I just haven't got around to it yet ... other fish to fry. Or rather raised beds to construct. (To be fair someone else did most of the constructing - I was more of a foreperson. And a sem-grumpy one at that, if I recall correctly.)
I've invested in some Link-a-Bord raised beds and very fine they are too, and a doddle to put together, AND made out of recycled plastic so far "greener" than using virgin wood. Two are up, and I have another three to put in place when the ground's prepared. The great thing is, if and when I move home - and thus allotment - I can easily lift them out of the ground and take them along with me.
