Thin seedlings to proper spacing for good air circulation and to discourage mildew. Keep faded flowers removed. Lemon & Orange Twist are easy to grow spring annuals, producing sturdy plants soon covered with bright flowers that bloom nonstop and attract butterflies for many weeks. In mild climates: sow again in late summer for winter or early spring flowers.
TO START OUTDOORS
Calendulas bloom best in cool weather, so plant in early spring in well-drained soil after danger of frost is over. Sow seeds 1 in. apart, cover 1/2 in. deep, firm soil and keep seed bed moist while awaiting germination in 7 to 14 days. After seedlings are well established, thin or transplant 8 in. apart.
Container growing: plants also grow and bloom well in pots at least 12 to 16 in. deep and 18 to 20 in. across. Start with fresh potting mix each season, keep well watered and fertilize monthly.
