To return to our Rugosas. The second group contains those of the Conrad F. Meyer type, great, strong growers with very thorny stems. These do not give any choice of method for they should have very little pruning at all.

We should confine our operations to merely removing damaged wood and thinning out that of two years and upwards. When, however, it is possible to do so, some at least of the branches should be bent and tied down, either permanently or till the buds towards the base have started. The fault of the Roses in this group is that they are not naturally very free flowering, so everything should be done to induce them to shoot from the whole length of the stem, otherwise the crop of flowers will be small. So far as I can judge, the new yellow Rugosa, "Daniel Leseuer," which seems very nearly related to the Dijon Teas, should be treated in the same way as those of this group.
