Blue Poppy Himalayan Blue Meconopsis Perennial Flowering Home Garden Seeds Plant Cultivation Seedlings are cold hardy and plants form larger blossoms and seed heads when grown in cool weather. Several weeks after seedling establishment but before seedlings are 6 inches tall, thin plants to 4 or 6 inches apart. Thinning can be avoided by using transplants in place of direct seeding; however, poppies do not transplant well. If transplants are used, germinate and grow plants at 60F. Grow seedlings for 4-6 weeks and plant out around the last frost date for the area. Transplant carefully to minimize damage the roots while planting. Water After seeding or transplanting, keep the seed bed moist until seedling emerge or transplants are established. Various methods of irrigation may be used as long as the seeds are not washed away before they germinate and become established. After final thinning, water needs are low about one inch per week, depending on weather conditions. Fertilizer In addition to fertilizers applied at soil preparation, seed yield increases when plants are fertilized with additional nitrogen. Sidedress poppy plants with 1-2 tablespoons of 21-0-0 per 10 ft. of row after thinning and before flowering to maintain vigorous growth.
