Planting Information:
Sow seeds 1/4” deep (just barely cover) 4 inches apart. Thin successful seedlings to 12-18” apart. Thinning is important; crowded plants may bolt and go to seed. Keeping the soil moist is imperative not only through germination but also throughout the growing season. Lack of water will slow growth and cause the leaves to become bitter. You can also start indoors and then set out once temps are reliably below 80°.
BLANCHING: Endive is commonly blanched to remove some of the bitter flavors. Blanching covers the heart of the plant depriving leaves of sunlight and slowing the production of chlorophyll which causes bitterness. Blanch endive 2 to 3 weeks before mature harvest. Here are three ways to blanch endive: 1. Pull the outer leaves together and hold them in place with a tied string or rubber band; be sure leaves are not wet before pulling them together or they may rot; 2. Lay a board on supports over the center of the row that shades the center of the plants; 3. Place a flowerpot over each plant. Plants will be blanched in two to three weeks.
