Tips for growing Agastache

Agastache are sun loving plants with aromatic foliage and flowers. They bloom from mid-summer into early fall and are resistant to rabbits and deer.

Agastache need lean, well-drained soils, prefer gravel mulches, and appreciate deep but infrequent watering after their second growing season

  1. Provide a fast draining soil that's naturally low in fertility, Don't plant into clay soils.
  2. Plant in full hot sun.
  3. Just a few handfuls of compost in the planting hole is enough. Don't plant into a rich, highly amended soil..
  4. Fertilize the Agastache just once in fall with Yum Yum Mix and Planters II.
  5. New transplants need regular irrigation their first growing season to establish themselves. Watering can be reduced greatly during the second growing season when the plants have matured.

To improve winter-hardiness, and encourage re-seeding, leave the stems intact over the winter. In mid-spring, remove old stems just above the new foliage, about 4 or 5 inches above ground level.

If your conditions don't lend themselves to growing Agastache in your garden, they do well planted in containers.

Q & A

USDA Hardiness Planting Zones

To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.

  • If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will survive the winter temperatures in your area.
  • If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack of freezing winter temperatures do not provide a time for winter dormancy (rest).
