Growing notes

Broccoli needs steady, even moisture — roughly 1 to 1.5 inches per week — to develop large, tender heads. The crop is shallow-rooted and unforgiving of drought: let it dry out at the wrong moment and the head buttons (forms tiny, premature) or turns tough and bitter. Water deeply at the base rather than overhead, which keeps foliage dry and discourages disease. The most critical stretch is the few weeks of head formation, when a single dry spell can ruin the crown. A 2–3 inch mulch of straw or compost steadies soil moisture and keeps roots cool, which matters most as the season warms toward harvest.
