Experiment with creating new lavender plants by propagating a lavender plant that is already thriving in your herb garden. Root cuttings from lavender quickly and easily by taking stem cuttings from your healthy lavender plant. With little coaxing or care, you will soon have new lavender plants to add to your garden or give to friends.
Cut vibrant stems with growth from the current season. Select stems without flowers, removing the stems down to the point where the new growth attaches to the old growth. This point is the "heel" and the heel is the point where the new roots will grow.
Fill the planting container with a mixture of one part coarse sand and one part potting soil. Spray the planting medium with the spray bottle to moisten the soil.
Cut away all lower leaves from the stem and insert the bottom inch of the stem into rooting hormone to coat it completely. Leave the upper leaves on the stem.
Insert your finger into the planting medium to make an indentation. Place the lavender cutting into the indentation and firm the soil gently around the stem.
Add additional stems to the same container if you desire. Space the stems approximately 2 inches apart in the soil.
Place the plastic bag over the top of the container and attach the bag to the container by fitting the rubber band down around the rim to hold the bag in place.
Place the container in a warm location without direct sunlight. Remove the bag carefully each day and spray the surface of the soil with the spray bottle. Replace the bag.
Watch the cuttings for signs of rooting. When you notice new growth on the stems, this indicates that roots are forming beneath the soil. Poke several holes in the bag to allow some fresh air to get to the cuttings at this time.
Remove the plastic bag approximately two to three weeks after you notice the new growth. Continue to keep the soil evenly moist.
Transplant the lavender cuttings to permanent containers or a growing location outdoors about one month after you remove the bag.
