Water from observation, not a fixed weekly rule

Check the root zone, plant, rain, wind, container and restrictions before deciding when and how much to water.

Editorial guidance without independent agronomic review

A watering can applying water to the root zone of herbs and vegetables in containers.

A calendar cannot know today’s demand

Rain, heat, wind, humidity, crop size, root occupancy, pot material and growing medium change water use. The same crop can need different checks on adjacent days.

Look below the surface

Compare moisture below the top layer, safe pot weight, recent weather, drainage and plant posture. A dry crust can cover moist compost, while a wet surface can hide saturated roots.

Wet the occupied root zone

Apply water slowly enough to enter the medium and spread through the rooted volume. Stop if it runs across a path, toward a building detail or through a blocked outlet.

Follow current local restrictions

Check the relevant water company, council, allotment or devolved authority when restrictions are possible. A broad crop guide never overrides a current hosepipe ban or site rule.
