Vegetative Growth
30-40 daysPlant develops multiple stems and narrow, lance-shaped foliage with a silvery-gray appearance. Height increases steadily
Thin seedlings to 12 inches apart. Fertilize every 2 weeks with balanced fertilizer. Pinch growing tips at 4-6 inches to encourage bushier growth if desired
