Tips

• Press tiny seeds onto the surface of moist seed-starting mix without burying them, and space hardened transplants about 8 inches apart.
• Provide about 1 inch of water weekly at soil level, keeping the root zone evenly moist but not saturated.
• Apply a balanced fertilizer at the labeled rate after transplants establish.
• Inspect leaves for rust pustules and remove infected tissue while improving air circulation.
• Remove spent flower spikes above a healthy side shoot to encourage repeat flowering.
