Article V. — On retarding the blooming season of the common French and English Roses.
By Mr. J. Hayward
May 21st, 1831

The nobility and gentry who remain from their country seats till late in the summer, are generally prevented from seeing this class of flowering shrubs, in perfection, but the following practice causing them to blow three or four weeks later than when grown in the usual manner, well merits attention from those persons who are desirous of having Roses to bloom as late as August and September.

The border in which the shrubs are planted, is manured with well-rotted cow-dung, about the first week in February. The shrubs are not pruned during the autumn or the early part of the winter, but remain untouched till the buds have pushed, some of them half an inch long; the shoots are then shortened below where the buds have pushed. The shortening the shoots so late in the spring, does not in the least weaken the shrubs, they blossom as vigorously and as freely as in the usual mode of treatment.

When desirable to have the blooming season prolonged, a portion of the Roses cut, as is here described, while the remainder are treated in the usual way, will produce the desired end.
