Climbing plants on the balcony: a living screen in pots, and frost

Which climbers actually close a balcony, how large the pot must be, and why hardiness in a container is a different thing from hardiness in a bed.

Freshly harvested beetroot with soil still clinging to it, in a shallow wicker basket on wooden floorboards

Self-Sufficiency

Storing potatoes and root vegetables: cold, dark, kept apart

Lawn

Getting the lawn ready for autumn: potassium, the last cut and leaves

From mid September · CW 38 what your lawn needs is potassium, not fast-acting nitrogen. Add the last cut to 4 to 5 cm between CW 44 and CW 46 and clear the leaves regularly. That is how the sward gets through winter without snow mould and moss.

Drying and Dehydrating: How to Preserve Fruit, Vegetables and Herbs

Herbs at 35 to 40 degrees, fruit at 50 to 70, vegetables at 50 to 60: which temperature each crop wants, how an oven and a dehydrator compare, how the bend test and the snap test tell you when a batch is done, and why the sweat test in a screw top jar is what really decides how long your store keeps.

Lawn

Mowing your lawn properly: cutting height, rhythm and the one-third rule

Cutting too short is the most common lawn mistake. Why grass tolerates mowing at all, how the one-third rule works in practice, which cutting height suits which patch, why a sharp blade spares the grass and what to do with the clippings.
