Water:
Originating from regions with seasonal rainfall, field indian paintbrush thrives with moderate weekly watering that keeps its soil moist but not waterlogged. It has moderate drought tolerance and may need supplemental irrigation during extended dry spells to maintain optimal growing conditions.
Fertilize:
For field indian paintbrush, use a balanced fertilization strategy during growth, shifting to high-nitrogen monthly in spring and summer, less in fall. Apply sparingly to prevent root burn. Being hemiparasitic, monitor nutrient use from neighbors. Employ a slow-release formula, watering soil before and after applications.
