Early Jade

START SEEDS DIRECTLY IN THE GARDEN In very early spring as soon as ground can be worked, prepare a well-drained, fertile garden bed in full sun. Sow seeds 2 inches apart in rows 6 to 8 inches apart. Cover 1/2 inch deep and keep soil evenly moist to ensure good germination. When seedlings are 3 to 4 inches tall, thin to stand 4 to 6 inches apart.    GROWING NOTES Sow Gai Lan in cool early spring weather, about the same time as you plant turnips and radishes. Consistent moisture, early thinning and an adequate supply of nitrogen will encourage the quick growth needed to produce thick, juicy stalks of leaves and flower buds. Use non-toxic Bt (Bacillus thuringiensis) products to control caterpillar pests as necessary. Make several sowings a week apart for a continuous harvest. Sow again in late summer for a fall crop.   HARVEST AND USE Harvest both leaves and flowering stalks at 7 to 8 inches tall, when stalks are still tender. After cutting, water plants and feed with fish emulsion solution to get a second harvest in a few weeks. Enjoy the broccoli-like flavor of vitamin-rich Gai Lan by quickly stirfrying with ginger and garlic. Oyster or black bean sauce and a spritz of toasted sesame oil and hot sauce are other tasty additions..
