Broccoli, also sold as calabrese (Brassica oleracea var. italica), is a member of the cabbage family grown for its dense green flower head and tender stalk. It is one of the most rewarding cool-season vegetables you can raise in an Egyptian winter garden, and with the right timing it produces a generous central head plus a run of smaller side shoots.
Broccoli is a cool-season brassica that thrives at roughly 7-21 C. Egypt's mild winters from November through February suit it almost perfectly, while the hot summer is unsuitable. The catch is heat: once daytime temperatures stay consistently above about 24-25 C the plant bolts, racing to flower and forming loose, bitter heads instead of a tight one. Grow it through the cool months and you sidestep that problem entirely.
Aim for heads to mature in the coolest part of winter. In the Nile Delta and Lower Egypt, sow in September-October for autumn transplanting and heading through the cool November-January window; this is also Egypt's main commercial broccoli belt. In Upper Egypt, which is hotter and more continental, shift sowing slightly later to October-November so head formation lands in the coldest weeks and early-autumn heat does not trigger bolting. Across the country, the practical growing-and-harvest window runs roughly November-March. Avoid sowing for summer maturity.
Broccoli is easiest raised as transplants. Start seed about 5-6 weeks before your intended transplant date, sowing about 2 cm deep into modules or a seedbed. Keep the soil warm and moist; optimal germination is around 25 C and seedlings emerge in about 10-21 days. Thin to one strong seedling per module, or to about 7.5 cm apart in a seedbed.
Set plants out when they have four or five true leaves, at roughly four to six weeks old. Choose a spot in full sun. Space plants about 60-80 cm apart with a similar gap between rows for full-size heads; a tighter 20-30 cm spacing in rows 60-90 cm apart gives smaller main heads if space is short.
At transplanting, water in with a starter or half-strength feed to settle roots. Once plants are established and about 10 cm tall, side-dress with nitrogen to drive leafy growth; on poorer soils an organic high-nitrogen feed when plants reach about 20 cm works well. A second feed at midseason supports strong head development. Steady feeding is what turns a small plant into a full central head.
Consistent moisture is essential. Provide about 2.5-5 cm of water per week, leaning to the higher end on sandy soils, and keep the soil moist but never waterlogged. Water stress during head formation is a leading cause of poor, uneven heads, so do not let plants dry out as the head swells. Watch for cabbage caterpillars, flea beetles, cabbage root fly, mealy cabbage aphid, whitefly, and slugs or snails; netting young plants and hand-picking caterpillars go a long way. The main diseases are clubroot, black rot, Alternaria leaf spot and white blister, so rotate away from cabbage-family crops for a few seasons to keep soil clean.
Cut the central head while it is full-sized but still tight and firm, with all the buds closed and before any yellow flowers open. A typical main head is about 7-10 cm across at cutting. Slice it off with a sharp knife and leave the plant in the ground: it will push out smaller side shoots over the following weeks for a second, lighter pick. In Egypt's winter window this means harvesting roughly through November-March.
Start with quality seed suited to a cool Egyptian season. At tna W rna you can order broccoli seeds for your autumn sowing, and there are additional broccoli seed packs and another broccoli seed option if you want to compare cultivars or sow a second succession. Pick your seed, sow in September-October (a little later in Upper Egypt), and you'll be cutting tight green heads through the cool months.
