Propagation by seed is limited to the efforts to obtain new varieties after cross-fertilization, and is a discouragingly slow and uncertain process.
WINTER PROTECTION
It will be a red-letter day for amateur rosarians when the existing favorites among rose plants shall have been so improved by cross-breeding that we can leave off all the winter overcoats of straw, brush and earth, with the happy knowledge that spring will find as many live plants in the rose garden as we rejoiced in during the previous season.
In England the "standard" rose, having a long stem of the foster stock, is quite common. With us it is less frequently seen on account of the bother of proper winter protection.
Although the Hybrid Perpetuals are, for the most part, sufficiently hardy to withstand an ordinary winter unprotected, it is still the part of wisdom to conserve their energy and health by hoeing up the earth about their bases and putting over all a top dressing of rough manure when protecting the Hybrid Teas and Teas. In the northern states it will be well to tie up the tops of the latter with straw or to surround the bed with a border of boards or wire netting, after winter has set in, and cover the plants with a thick blanket of leaves held down by brush. This protection should be removed gradually in March.
Where the winters are particularly severe, a still more certain precaution is to dig up the plants and lay them in well-drained trenches, covering them with earth and a further layer of leaves, straw or brush. The aim is not to protect the plants from freezing at all, but to prevent the alternate freezing and thawing that is so disastrous.
Another treatment for tender roses is to winter them in boxes of soil in a cool cellar. In case this is done, see that the earth is not allowed to dry out entirely. At planting time in the spring the dormant plants will be taken out, dipped in a bucket of thin mud and replanted in the garden.
While we may be willing for the present to take such precautions with the garden roses, most of us will not care to coddle the climbers to anything like this extent. Beyond hoeing up a mound of earth about the bases of these and top-dressing them, we shall let the climbers fight their own battles, and leave the result to the principle of the survival of the fittest.
