When rose garden beds have been properly prepared by the introduction of plant food in the form of manure, bone, and lime, all that remains to be done in the way of fertilization may be easily attended to by top-dressing from time to time. Liquid manure should never be given in dry weather without first thoroughly wetting the soil with plain water, but it may be used at frequent intervals provided it is not too strong. Dried blood may be used either in water or dry at the rate of one ounce to the square yard during May, June, and July if hoed well into the surface soil. Wood ashes and bone meal in small quantities may be used in a similar manner after growth starts. These dry fertilizers should be used only just before a good rain or should be followed by a thorough soaking with the hose.

Wall Garden. The wall garden is perhaps one of the most interesting types of gardens. A wall garden should never be attempted unless those responsible for its maintenance feel certain that the proper kind of intelligent maintenance care can be devoted to such a garden. A list of plants which are adapted for producing wall garden effects is small. It is not so much the question of quantity of maintenance as it is the question of the degree of intelligent maintenance which makes for the failure or success of the wall garden. The greatest success is attained with wall garden development when those responsible for its maintenance make it a special point to thoroughly familiarize themselves with the growing habits and the requirements of wall garden plants. If this is not done the garden is very apt to deteriorate into a normal type of garden with a few persistent weeds of various kinds and some of the more common and easily growing annuals like alyssum growing from the crevices of the rocks.

Water Garden

The water garden is the one garden which requires less attention than any other garden when it is once correctly developed. The main problem is that of keeping a supply of water which is in no degree stagnant and in knowing the requirements for the fertilizing of aquatic plants to produce the best development.
