Allotment Basics for Beginners
The short answer
A full UK allotment plot is 10 rods, roughly 250 sq m (300 sq yd), which is more than many new plot-holders can keep on top of - half plots are usually available and are a sensible starting point.
Clear the plot in stages (debris first, then woody plants, then perennial weed roots, or smother with opaque mulch over a growing season), and make a realistic plan for year one, year two and beyond rather than trying to bring the whole plot into cultivation at once.
How big is a plot, and should you take a full one?
The RHS notes that a full allotment plot is 10 rods, approximately 250 sq m (300 sq yd). That is a substantial area - enough to grow a great deal, but also enough to overwhelm someone new to growing.
Half plots are usually available if a full plot is too much to manage, and for a first year they are a realistic choice. It is far better to keep a half plot productive and enjoyable than to let a full plot run to weeds.
Clearing an overgrown plot
Many allotments are handed over overgrown. The RHS sequence is to first clear the plot of unwanted materials and debris, then remove trees, shrubs and woody plants by cutting and digging, and then tackle perennial weed roots.
An alternative to digging out weeds is to smother them with opaque mulches, but this requires at least one growing season to work. Either way, work in sections rather than trying to clear the whole plot in one go.
Plan realistically and start simple
The RHS advice is to make a realistic plan of what you can achieve in year one, year two and so on, rather than rushing to full cultivation. Cover ground you are not yet using with mulch or a cover crop so it does not run back to weeds.
For a shadier plot, the RHS suggests shade-tolerant crops like beetroot, chard, kale, kohl rabi and lettuce, plus fruit such as redcurrants and raspberries. Forgiving, fast crops in year one build confidence while you get the rest of the plot in shape.
