Growing Instructions

1. Select a well-drained location away from trees and hedges where there is sun at least half a day. 2. Prepare the site by digging a hole 12-15" deep and about the same width. If available add 6-8" of compost, manure or top soil. 3. Best to plant immediately upon arrival. Remove packaging and soak the in water for about an hour. Prune the canes back to about 1" above the bud union. Spread the roots out evenly into the prepared hole. Plant at a depth with the bud union (where the branches come together) about 1" above the soil level after back filling the hole. 4. Best to mound soil or mulch over the bud union until the danger of frost has passed - removing once new growth is observed. 5. Soak soil every week until established when rain fall is deficient. 6. Fertilize with a season-long balanced fertilizer once leaves start to emerge.

Care Tip

Pruning an inch or so off the canes will help send a message to the rose that it is time to start growing once again.
