Quick guides

Keep a bought or home-raised punnet healthy for a week or two with bright shade, bottom watering as the mix dries and a weak feed, and know when to pot on and how to plant out.

Sow two or three cucurbit seeds per station, pick the strongest seedling at the first true leaf, and snip the rest at soil level so the keeper has the space to itself.

Tell when a seedling has outgrown its cell, then move it up one pot size without damaging the stem, so it keeps growing until the garden is ready for it.
