Foliar Feeding
Although most of the nutrient needs of plants, including roses, are met by absorption through the roots, the leaves can also absorb fertilizers to some extent. Fish emulsion and liquid seaweed, either alone or in combination, are particularly beneficial as a foliar feed for roses. Not only do these provide a boost of extra nutrition when plants are growing at a maximum rate, but they also repel some harmful insects. Thoroughly wet the foliage with the spray.
Cutting and Conditioning Roses
For the longest vase life, cut roses either in the early morning or evening when they contain the most water. Using pruning shears, cut the stem at an angle just above an outward-facing leaf. Remove foliage from the bottom 3 to 4 inches of stem. Recut the stem underwater at an angle, removing 1/2 inch of stem, then place in a container with water and a floral conditioner. Set in a humid, cool, dim place for several hours before making your arrangement.
Pruning Roses
Prune once-flowering roses as soon as possible after they've finished blooming. This gives them a long season to develop canes that will bloom next year. Deadhead repeat-flowering roses throughout the growing season. Prune and shape plants, as necessary up until about six weeks before the expected date of the first hard freeze. On roses known for their decorative, seed-bearing hips, remove only the untidy or old, nonproductive canes.
Select Rose Companions
The best companion plants for roses are small in stature, so that they don't block sunshine and fresh air. Frothy sweet alyssum is one of my favorites. This easy little annual is a perfect plant to grow at the feet of elegant roses.
