Coleus
Solenostemon scutellarioides “Rainbow Mix”
Coleus is known for its strikingly colorful foliage and shade to part shade loving habit. Rainbow Mix is a sampling of varieties that will produce a dramatic display. It is an excellent feature plant in containers.
When to Plant Outdoors
Coleus does well in hot weather, but not in intense direct sunlight. Install after all danger of frost is past and when the soil no longer feels cold to the touch.
Moisten prepared soil thoroughly. Using scissors, cut seed mats as desired. Each mat can yield 2, 3, 6, or 12 sections depending on your needs. Now, place each section where desired on the moistened soil and water thoroughly. Seed in a Blanket® is designed to hug the ground when moistened so it will stay in place. At this point, it cannot be lifted up in one piece. Do not cover mat with soil.
Water frequently to keep seed mat moist until the second set of leaves are fully extended. Do not let the mat dry out. Germination should occur within 1 to 2 weeks at around 70ºF or warmer.
When to Start Indoors
In a warm, well-lit location, start 10 to 12 weeks before the last expected frost. Using scissors cut each mat into 6 to 12 sections as desired. Place sections on well moistened soil-less potting mix in containers that allow good drainage. Water until the mat is thoroughly moistened and hugs the planting medium. Water evenly and do not let the mat dry out. Expect germination within 1 to 2 weeks. If germination is delayed, provide more warmth up to 80º until seedlings appear.
After the second set of leaves are fully extended, transplant seedlings into individual pots. When all danger of frost is past and the soil in your garden is no longer cold to the touch, move to a shady and protected area outside for one week before installing in its intended position in the garden. This is an important step that will allow the seedlings to adjust to conditions outside.
Tip – Keep planting area weed-free. Pinch back and remove flower clusters to promote a bushier plant. Cuttings will often root easily directly in moist soil or in a container of water. Colors will be more vivid in a shadier spot.
