I am unable to understand why my roses supply a small amount of blooms. I have used Vigoro for roses. Would too little water be a factor?

For roses to thrive they require all day sunshine, adequate water, adequate food and annual pruning. It's also important to remove spent flowers throughout the season. Here are some basics on rose care:

In general, they need full sun (8-10 hours a day in summer), and good air circulation. Water them deeply, about 1-inch of water per week. Use 2-3 inches of compost or other organic matter to mulch the root area, to help protect the roots and to retain moisture. During the season remove spent blooms so more blossoms will be produced, and begin feeding in February when new growth appears. You can use an 8-12-4 or 8-8-8 formula of commercial rose food, though a rich, organic soil supplemented with occasional doses of fish emulsion is usually enough for them.
