How to Grow Creeping Rosemary Indoors

Creeping or prostrate rosemary (Rosmarinus officinalis "Prostratus") forms a low growing shrub up to 20 inches wide if left alone outdoors. When planted in containers, this plant can come inside for the winter or the whole year. Rosemary plants in general are finicky; they enjoy a cool, moist climate, but too much of either indoors promotes conditions that harm the plant. Likewise, excess dry heat kills rosemary. Monitor your rosemary regularly to keep it healthy.

Instructions

    • 1

      Fill a container with drainage holes halfway with a well draining potting soil. Do not try growing creeping rosemary in containers without drainage holes, because this will lead to root rot.

    • 2

      Remove your creeping rosemary from its plastic pot and place it in the prepared container. The plant should sit at the same depth as it did in the plastic pot; adjust its level by adding or removing soil beneath the roots, if necessary. Next, top off the soil level, firming soil around the plant, to complete planting.

    • 3

      Water the plant to saturate the soil and remove air bubbles. Allow the liquid to fully drain.

    • 4

      Place the creeping rosemary in a bright sunny window, or another location where it receives as much sun as possible. The more light the plant gets, the more successful it will be.

    • 5

      Water your rosemary when the soil becomes dry to the touch, adding enough liquid to moisten the soil. Do not water the plant so much that the soil becomes boggy or waterlogged. Err on the side of watering slightly less, since root rot from overwatering is a major danger of keeping rosemary indoors.

    • 6

      Watch out for houseplant pests that can bother your rosemary. Evidence of pests include sticky substances on the leaves, holes in the leaves, visible pest presence and distorted growth. Treat infected plants with insecticidal soap.

    • 7

      Trim rosemary when then tendrils grow too long. Use the cut shoots for cooking. Cut additional rosemary when needed in the kitchen.

    • 8

      Move the plant outdoors in the late spring to summer, if you have access to outdoor space. Rosemary in containers does better with sun and fresh air. If you move the plant outside for part of the year, your creeping rosemary comes indoors refreshed and hearty. If you don't have access to outside space, continue to care for your rosemary inside.
