Answer: Exposure to direct sunshine all day is one important factor in producing blooms, but pruning, fertilizing and watering practices are also important. Most roses need direct sunshine most of the day. Climbers produce flowering shoots from main canes, so when you prune, take off most of the current season's wood, cutting back to the basic structure of the plant. (You should have several mature canes on an established climber.) Then, in the spring when new growth begins, the shoots that develop from the main structure will be flower producing shoots. If you fertilize too often, or with a high nitrogen fertilizer, you'll be encouraging lush green growth at the expense of blooms. Use an 8-12-4 commercial fertilizer, making three applications per year (in spring, early summer and late summer). Apply an organic mulch over the roots of your roses to help the soil retain moisture and to help suppress weeds. Finally, apply about one-inch of water per week to your roses, making sure that the entire root mass gets wet. Following the above guidelines should help your roses produce and abundance of blooms next season.
