ðą How to Care for Myrtle spurge to Prevent Aphids?
ð§ How to Water
Drought tolerant. Once established in the ground, rain is usually enough; in a pot, water only when the soil is completely dry, about every 14 days in warm weather and much less in winter. Soggy soil rots the roots.
âïļ Lighting
Full sun, at least 6 hours a day. In shade the stems get long and floppy and lose their blue color.
ðŠī Ideal Soil
Dry, lean, sharply drained soil: sandy, gravelly or rocky. Acid, neutral or alkaline soil is fine, but it will not tolerate ground that stays wet.
