Water sparingly, allowing the soil to dry out completely between waterings. Overwatering is detrimental, especially during dormancy. Ensure good drainage to prevent root rot.

Reduce watering significantly in cooler months when growth slows.

Pruning is generally not required. Remove any dead or damaged foliage as needed to maintain a tidy appearance. This plant is not typically pruned for shape or size control; focus on its natural growth habit.

Propagation is primarily done through seed. Seeds require specific scarification or stratification treatments and are best sown in spring. Vegetative propagation is difficult and not commonly practiced.

Repotting is rarely necessary for this parasitic plant. If a host plant outgrows its container or requires repotting, carefully detach the Hyobanche barklyi without damaging its haustoria. Use a well-draining substrate.
