Coleus Collector

Coleus now comes in hundreds of varieties that offer season-long color and texture. No longer just for the shade garden, there's a big selection of sun coleus too. Coleus grows in the ground as well as in containers. Growing habits range from tall to small upright varieties to trailing or sprawling types. Tammy Algood introduces us to a home gardener who is a big fan of coleus who demonstrates how easy it is to propagate from cuttings.

Bare Root Tree Stock on NPT's Volunteer Gardener

Bare Root Tree Stock

The cost of a bare root tree is typically 1/4 the cost of ball and burlap ones of similar size. Wanting to make the biggest impact toward the Root Nashville campaign to plant a half million trees by 2050, Metro Water Services in Davidson County TN is nurturing 100 bare root trees. To successfully do that, they've built a raised bed and filled it with gravel. The bare root trees are held here, getting regular irrigation, for 3-6 months. During this time their root systems will grow stronger and ready for planting.
