Western One-Flowered Broomrape (Aphyllon purpureum) requires watering once per week in the summer months. Water thoroughly until water is seen draining from the bottom of the pot or container. Make sure to check the soil moisture level every few days since this species is very sensitive to drainage issues. In winter it is best to allow the soil to dry out between waterings. Make sure to keep the soil evenly moist but not soggy. Avoid over-watering as this can cause root rot or fungal diseases that can ultimately kill the plant.

Western One-Flowered Broomrape (Aphyllon purpureum) grows best when it receives 8-10 hours of full sun each day during its growing season. The optimum amount of sunlight for this species of plant is northern exposure during the spring and early summer months. If Aphyllon purpureum receives less sunlight than this, it may suffer stunted growth, flowering, or death. When possible, the plant should be placed in a location with direct sunlight or shade created by trees or buildings to provide partial shade. To ensure maximum productivity, it is best to keep the plant in full sun during the warmer months of spring and summer and partial shade in the cooler months of fall and winter.

Pruning for Western One-Flowered Broomrape should be done once a year, during the mid-summer months. Pruning should include cutting back unproductive stems and any discolored foliage. Additionally, unopened buds should be trimmed off before they reach maturity, typically in early summer. This will prevent the plant from producing too many stems, resulting in a weak and lanky plant. Additionally, since this species is very drought-tolerant, overcrowding should be minimized. Pruning should also involve thinning out the plant to improve air circulation. This will help reduce the chances of fungal diseases.
