Water: Originating from arid regions, white milkwort exhibits high drought tolerance and thrives with minimal moisture. It requires infrequent deep watering weekly, prefers well-draining soil to prevent waterlogging, and is typically grown outdoors to replicate its natural habitat.

Fertilize: Fertilize white milkwort biweekly in spring and summer with balanced nutrition; reduce to monthly in fall, and only if necessary in winter. Use a diluted solution to avoid root burn and support natural growth, adjusting based on lifecycle changes while following product dosage guidelines.

Pruning: White milkwort features small, white flowers and bushy growth. Prune in early to late spring to promote healthy growth and enhance blooming. Use sharp, clean tools and target dead or damaged branches. Optimal pruning timing aligns with its active growth phase for best results.

Propagation: White milkwort propagates mainly through cuttings taken from healthy, non-flowering stems during active growth. Use a well-draining medium and maintain moisture. Indirect bright light aids rooting. Once roots form, acclimatize the cutting to standard growing conditions.
