"The dahlia is very variable, sporting from its true colours, but as often re- turning to them. Knowing this, let the following facts, with regard to new kinds of dahlias, be borne in mind before condemning them the second year: -
" 1. That the seedling plant is much debilitated by propagation; and there-: fore the flowers are rarely as good the second season as they are the first and subsequent to the second.
"2. That the best flowers are obtained from those plants struck from the first cuttings produced by the mother-plant, notwithstanding that they are seldom as strong as the cuttings that are afterwards produced.
"3. The exciting the roots by means of a strong heat early in the spring, and striking the young plants in a strong dung-bed, tend to weaken the plants so treated to such a degree that they frequently require two or three seasons to recover and regain their original character. Thus it is found that good flowers are obtained with the least trouble from those plants kept in pots the first season after striking, (termed by the trade pot-roots,) planted out the following season, and allowed to start of their own accord.
"4. That in wet seasons manure is frequently very injurious from its causing the plant to grow too luxuriantly, and thus to produce but few flowers; while in very dry seasons it is equally injurious. Much more depends on a change of soil than on its composition and quality.
"5. That water is a point which cannot be too much attended to. A great difference exists between hard and soft water, but still more depends on the manner in which it is applied; for one or two good waterings are much better than a small quantity given three or four times a week.
"6. That taking up the roots immediately after a frost has destroyed the top, is the principal cause of so many roots dying during the winter season." - Gard. Chron.
