Mojave Poppy is drought-tolerant once established. Water deeply but infrequently, allowing the soil to dry out completely between waterings.

Overwatering can lead to root rot, especially in well-draining soils common to its native habitat. Reduce watering significantly during its dormant summer period.

Deadheading spent flowers can encourage further blooming and prevent self-seeding if unwanted. Minimal pruning is generally needed.

Remove any dead or damaged foliage at the end of the growing season to maintain plant health and appearance. Avoid heavy pruning.

Mojave Poppy is easily propagated by seed sown directly into the garden in autumn or early spring. Seeds require light stratification and benefit from being sown on the soil surface.

Germination can be erratic and slow, so patience is key. Transplanting established plants is not recommended.

Repotting is generally not recommended for Eschscholzia glyptosperma, as they do not transplant well and prefer to be established directly in the ground. If starting from seed indoors, transplant seedlings into their final garden location as soon as they are large enough to handle, disturbing the roots as little as possible.
