Outdoors: After the last frost date in your planting zone, plant Kangaroo paw in the spring. Choose a full sun (6-8 hours) area. Too little sunlight can cause week stems and floppiness and inhibit flowering. Cultivate the native soil for good drainage with organic matter like compost, and sand with slightly acidic soil pH. Be generous by digging a hole twice the pot's width and 1 inch shorter than the grower pot to raise it above the soil level for good drainage. Use a pitchfork or a sharp object to stab the soil walls to make several indentions for the roots to take hold. Tickle the roots to loosen them if they wrap inside the container. Place the plant in the center of the hole. Fill the hole with water first, so the roots get another good drink. Next, backfill with native soil mixed with compost by one-third to one-half (if the native soil is clay). Add a rooting hormone fertilizer to this backfill mixture. Tamp the soil firmly down around the edges and mound up. Avoid covering the original soil level of the plant that was in the container. Add mulch as needed but not next to the stem or branches of the plant. Water lightly. Continue to observe the soil moisture each day, depending on the temperatures and soil drainage. The soil needs to remain moist but not soggy during the growing season and until it gets established. Let it dry on the top few inches between waterings.
