Agastache Plant Care:
Good drainage is a must! Agastache thrive in full sun and rarely need divided. Most will self sow to spread, so deadhead by removing faded flowers to prevent seeding. Leave stems to overwinter; tip or remove new growth in early to mid spring for more flowering stems and a more compact plant. To promote strong stems, avoid too much water once established and fertilize only once every year or two in late fall to late winter.
