Agastache Planting Instructions

Planting Instructions for Agastache (anise hyssop, hummingbird mint):

Bloom Time:  Summer Light:  Full sun to part sun
Soil:  Average to rich, well-drained Moisture:  Average, drought tolerant
Planting Depth:  1/2 to 1" deep, mulch lightly Spacing:  18 to 24"

Upon arrival:  Unpack box and check that you have everything on your packing list. Bare root Agastache should be dry in the bags, so if condensation has formed on the inside of the bag, open and let it air out. Plant everything within a day or two.

Soil/Location:  Plant your Agastache in a sunny spot in average to rich, well-drained soil. Add compost or peat humus to enrich and loosen the soil if needed, but they are very adaptable to almost any soil conditions. Remember to keep the soil light and airy for perennials, so cover them with loose soil and don't pack it in after planting.

Moisture:  Agastache do not require much moisture, even after they are actively growing. Early season plantings (April and May) and plants that have no foliage should be started on the dry side. During that time we like to water lightly once and then we don't water again until the foliage has started to emerge. When actively growing they can be watered once or twice a week or as needed if they wilt, allowing the soil to dry out between watering, however they are quite drought tolerant once established.

Spacing:  18 to 24"

Depth:  Plant with the top of the crown about 1/2 to 1" below soil level. New sprouts will emerge at slightly varying depths but no roots should be showing after planting. Mulch lightly around the plants for weed prevention.

General Instructions:  Amend your garden with compost or peat humus to enrich or loosen the soil, if needed, however Agastache are very adaptable to any good, loose, well-draining soil. Mix a couple teaspoons of garden food or bone meal into the planting hole if desired. Plant the roots as listed above, then water in once lightly. They prefer a slightly dry start when they are dormant in spring and have no foliage. Once they are actively growing it is alright to give them supplemental water once or twice a week, if needed.

Landscape Uses:  Agastache makes a great addition to the butterfly and hummingbird garden or a natural wildflower garden. It works well with other late summer perennials such as garden phlox (Phlox paniculata), Japanese anemone, Aster, Boltonia, Rudbeckia, Helianthus, and Echinacea.

Some varieties can self seed freely. Deadheading can help to prevent unwanted seedlings as well as help them rebloom.
