For optimal growth, prepare the planting area by clearing any weeds and enriching the soil with organic matter like compost or well-rotted manure. When planting Ajuga Black Scallop, ensure proper spacing of about 30 cm between plants to allow for healthy growth and prevent overcrowding. Plant at the same depth as they were in their original pot or container, and water generously after planting to establish strong roots.

Watering & Feeding

For Ajuga Black Scallop, ensure consistent watering during the growing season, especially in the warmer months, with a frequency of at least once a week until established.
