Growing Tips
Seeds are tiny and light-dependent; press gently into soil without deep burial. Provide bottom heat (heat mat) for optimal germination. Keep soil consistently moist but not waterlogged. Use vermiculite covering to retain moisture and prevent damping-off fungus. Do not allow seedlings to become root-bound; transplant when 3-4 inches tall. Avoid temperatures below 60°F as this causes stunted growth and premature flowering.
