Frequently Asked Questions

How often should I water Tropaeolum majus during the main growing phase?

Water deeply when the top 1 inch of soil feels dry, aiming for consistently lightly moist soil rather than wet conditions. During active flowering, this typically means watering about 2–3 times per week in warm weather, but less often if it rains or soil stays cool. Avoid keeping the soil waterlogged, which increases the risk of root problems and leaf spotting.

How do I know when Tropaeolum majus is ready to harvest?

Harvest seed pods and flowers based on maturity: flowers are best when fully open and fragrant, usually starting around 40 days from sowing. For seed, pick pods when they turn green-to-brown and feel firm, before they fully dry and drop. For continuous blooms, harvest flowers regularly and remove spent blossoms to encourage more flowering.
