Most hybrid teas are cared for in the same way. Here are the requirements for healthy hybrid tea rose growth. For lots of lush blooms, choose a site in full sun, set apart from trees and shrubs. Give the roses excellent drainage. If your soil is heavy clay, grow roses in a raised bed, or amend your soil with a suitable combination of compost, manure, or other organic matter. Mulch newly planted roses with a 2-3-inch blanket of shredded bark to help the soil stay moist, to stabilize soil temperature, and to suppress weeds. Water deeply each week at the base of the plant. Fertilize every 4-6 weeks after spring growth has begun. Cease fertilizing 6-8 weeks before the first fall frost. Prune annually, making sure you remove all dead, diseased wood and weak or crossing branches. Deadhead flowers as they fade to keep the roses blooming instead of spending energy producing seed. Prune out the center branches to promote good air circulation and prevent disease.
