Watering and Irrigation

Watering is the most common place beginners go wrong, in both directions. Too much drowns roots, too little stalls growth, and a fixed calendar ignores what the plant actually needs on any given day.

How much and how often

Water when the top of the growing medium dries out, and water thoroughly so the whole root zone gets wet, then let it dry again. Lift the container to learn its weight wet and dry; that feel beats any schedule. Seedlings need small, frequent water, while mature plants in large containers need larger, less frequent watering.

Irrigation options

Hand watering suits small grows and teaches you to read plants. Drip lines suit larger grows and vacations, delivering slow, even water to each plant. Whatever system you use, check it by hand regularly: a clogged emitter looks identical to a working one until a plant wilts.

Signs of watering trouble

Drooping leaves with wet medium usually mean overwatering, while drooping with dry medium usually means underwatering. Yellow lower leaves, slow growth, and root problems can follow either mistake. Fix watering first before changing nutrients, since most nutrient problems start as watering problems.
