How to Plant Proven Winners Plants
Water your potted Proven Winners plant prior to planting to get the roots thoroughly wet. Dig a hole 2 times wider than the container, but no deeper than the height of the root ball. When your plant is placed in the hole you should be able to see the top of the root ball slightly above the existing soil line. Backfill the soil and water deeply until the ground is fully saturated. Apply 1 to 2 inches of mulch to reduce weeds and protect the roots.
When to Plant Proven Winners Plants
The best time to plant Proven Winners is in spring or fall. We recommend that hardiness growing zones 3 to 7 plant at least 6 to 8 weeks before the ground freezes for best results. Growing zones 8 to 11 can plant anytime in fall and winter. Summer planting is fine in cooler regions, but keep the soil constantly moist.
How to Fertilize Proven Winners Plants
Use our balanced slow release fertilizer at the time of planting to boost the establishment of your Proven Winners plant. This specially formulated fertilizer feeds plants for up to 6 months and never causes fertilizer burn. Apply PlantingTree Slow Release Fertilizer each spring for best results. It is great for trees, shrubs, evergreens, perennials, and more.
