Porteranthus Planting Instructions

Planting Instructions for Porteranthus (Bowman's root):

Bloom Time:  Summer Light:  Full sun to part sun
Soil:  Slightly acidic, humus-rich, well-drained Moisture:  Average to slightly moist
Planting Depth:  dormant buds 1/4 to 1/2" deep, mulch lightly Spacing:  18 to 24" or more

Upon arrival:  Unpack box and check that you have everything on your packing list. Bare root Porteranthus should be somewhat dry in storage and generally you can leave the bag sealed and try to plant everything within a couple days.

Soil/Location:  Plant your Porteranthus in a sunny to partly sunny spot in average to humus-rich, loose and airy, moist but well-drained soil. Add compost or peat humus to enrich and loosen the soil if needed. Remember to keep the soil light and airy for perennials, so cover them with loose soil and don't pack it in after planting, and if needed build up above heavy soil rather than trying to plant into it.

Moisture:  Porteranthus is relatively drought tolerant but enjoyed fairly regular watering of at least a couple times per week. Early season plantings and plants that have no foliage should be started on the dry side but once emerged you can begin watering. To plant simply bury the roots with the top of the dormant buds underground and covered with about 1/4 to 1/2" of soil, water lightly once and then water again after they have emerged. When actively growing they can be watered a couple times a week if needed, allowing the soil to dry out between watering, and they are drought tolerant once established.

Spacing:  15 to 18" or more

Depth:  Plant with the top of the crown about 1/4 to 1/2" below soil level. New sprouts will emerge at slightly varying depths and no roots or crown 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. Mix a couple teaspoons of garden food such as Hollytone 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 a couple times per week.

Landscape Uses:  Plant Bowman's root in the mixed flower border with grasses, sedum, Echinacea, Rudbeckia, daylilies, lilies, and other sun loving perennials.  While they may need some support they are just as happy growing in a loose clump for a natural look in the garden.
