Kale and Collards



CULTURE: Plant approx. 3 months before expected fall frost. Sow 3 seeds every 8", 1/4- 1/2" deep, in rows 18-30" apart. Thin to 1 plant/group. You can also grow kale from transplants, like cabbage. Beginning about 2 months after planting, harvest by clipping individual leaves. For salad mix: In a 2-4" wide band sow 60 seeds/ft. Clip 4- to 5-week-old leaves. Kale and collards are very hardy, will increase in eating quality into late fall and will be harvestable through the winter in most areas. Use row cover in severe climates.
PESTS: They are not as afflicted with pests as are other cole crops like cabbage. Use row covers (see Index) to exclude pests from seedlings. Control cabbage worms with bacillus thuringiensis.
DAYS TO MATURITY: From direct seeding; subtract about 14 days if transplanting.
AVG. DIRECT SEEDING RATE: For bunching: 220'/1,000 seeds, 1,550'/oz., 24,000'/lb., at spacing above.
TRANSPLANTS: Avg. 5,500 plants/oz.
SIZED SEEDS: Where noted.
SEED SPECS: SEEDS/LB.: 90,000-150,000 (avg. 112,000).
