A perfect cabbage for home gardeners! This AAS winner provides an early yield of cabbage and is also ideal for CSA's as you can turn this crop over quickly and it will keep generating cash flow for your operation. Katarina takes up only one square foot of space so is well suited for planting in small gardens, raised beds or even in a large pot on the porch. The heads are small, round and perfectly formed with a small core. Excellent for both processing and eating fresh. 45-50 days to maturity.
Plant seeds 1⁄4-1⁄2 inches deep. Transplant or thin small plants to 15-18 inches apart in rows 32-36 inches apart. Transplants can be started in April for May planting. Transplant after 4-6 weeks. Use a starter fertilizer, soaking the root ball thoroughly prior to transplanting. Direct seed in late spring, as seedlings can tolerate a light frost. Broccoli can be direct seeded up until mid-late June for a continuous harvest. Soil temperature should be 21-26 degrees C for optimal germination in 4-7 days.
Cabbage prefers full sun, but will tolerate part shade. Prepare a rich, loose soil that holds moisture well and has pH level of 6.0-6.5. Broccoli is a heavy feeder and will also benefit from applications of boron, calcium and magnesium, particularly during the early stages of growth. Hollow stem in broccoli is related to boron deficiency.
Heads are ready when firm and when the interior is dense. Heads will split when over mature; rapid growth due to excess moisture and fertility will also cause splitting.
Allow 125g/acre if growing transplants; 500g/acre if direct seeding.
