Western Indian Paintbrush

Lesser Paintbrush (Castilleja minor) plants should be watered around 1 to 2 times per week. During the summer, water the plant once a week, and in the winter months, water it every 2 weeks. The soil should be kept moist at all times, not soggy. Additionally, water in the early morning or late evening to ensure the water has time to absorb before the sun has a chance to dry it up. Be sure to monitor the soil moisture, and if the soil feels dry, water the plant more frequently.

Lesser Paintbrush (Castilleja minor) requires direct sunlight 4-6 hours per day, including at least some morning sunlight. During peak summer months, plants may require more sun for maximum growth and flower production. When placed in full sun, the Lesser Paintbrush should not be subject to intense midday sun and should be protected from windy areas. Too much sun can lead to wilting, so the plant should be monitored for signs of distress when first exposed to full sun. Plants should also be monitored for signs of too little sunlight, which can include delayed flowering, poor coloration and general stunted growth.

Pruning Lesser Paintbrush (Castilleja minor) should be done in late winter or early spring, before growth begins. Prune sparingly and only if necessary. Remove any dead, damaged, or diseased stems, as well as any shoots or branches that cross or rub against each other. Cuts should always be made just above a bud. For maximum flowering, remove only a third of the stems each year. Don't prune too severely; pruning too harshly could damage young plants or delay flowering until the next year.
