Excessive alkalinity and acidity are disadvantages, but as both can be minimised quite easily, neither can be considered as prohibiting the growth of dahlias.
The dahlia will grow well in pra&ically every garden with little attention other than staking and tying. If, in addition, the ground is well tended and a little compost or manure added from time to time, then good results are certain.
Pompon dahlias are exactly like double show and fancy dahlias except that they are smaller. Divided into three groups: Large (over 3 in. but usually less than 4 in.), Medium (over 2 in. but usually less than 3 in.) and Small (less than 2 in.).
Although these ideal conditions will not be available to many gardeners the site and soil nearest approximating to them must be chosen, and, if really good results are desired, an attempt made by careful culture to minimise the natural disadvantages.
Yet it has been proved without doubt, during the many years that the dahlia has been cultivated in this country, that the majority of the species and garden hybrids will grow well in conditions very different from those of their native country.
Although these are the main groupings at present, there is no doubt that this classification will not remain unchanged for long as the dahlia exhibits new variations in form each year, some of which will ultimately have to be recognised. For example, there are an increasing number of cactus varieties in which the tips of the petals are laciniated, in many cases quite deeply. These frilled or lacy varieties are at present handicapped in competition against the more normal varieties, so that if the number increases it may well be advisable to institute a separate class for such varieties.
