Do I need to clear the whole allotment in the first year?

No. Clear enough ground to grow a useful first crop, then bring the rest into cultivation in planned stages. Confirm that this approach meets your tenancy's cultivation requirement before leaving a large area covered.

Set a realistic first boundary

The RHS specifically suggests clearing half a severely neglected plot in the first year when full clearance is unrealistic. Your sensible share may be smaller: it depends on plot size, condition, available time and the site's inspection rules.

Prioritise access, a composting area and one or two beds. Keep paths safe and prevent unmanaged weeds from setting seed. Covering unused soil with an opaque, securely fixed material can suppress growth, but the site manager should agree any extended period out of cultivation.

Show steady cultivation

A simple sketch and dated photographs help you track progress. Plan the next section before you uncover it so cleared soil does not sit empty and return to weeds. Choose a modest number of crops that you actually eat and can water reliably.
