Go through the garden with a view to finding what changes can be made advantageously. We often make sad mistakes in the location of our plants, and do not discover them until it is too late to unmake them that season. Sometimes a plant that has got into the wrong place so disappoints us that we think of throwing it out, but if we give it a place where its merits have an opportunity to assert themselves properly it turns out to be extremely satisfactory. The aim should be to get every plant into the place just suited to its peculiarities. It may take several seasons to bring about so desirable a result, but something along this line should be part of every season's work.
Old clumps of perennials will be greatly benefited by a division of their roots about once in three years. Take them up, cut their roots apart, discard all but the youngest and strongest ones, and reset in a soil that has been made rich and mellow.
Shrubs should be looked over with a view to doing whatever pruning may seem necessary. I do not advise much pruning, however. A shrub knows better than I do what shape to grow in to be most effective, and I prefer to let it train itself. About all the pruning I do is to cut away weak wood and to thin out the branches if there seems too many of them.
Early-flowering shrubs should never be pruned until after their flowering period is over.
Manure should be applied to all plants each spring. The older it is the better if you procure it from the barn-yard. On no account should fresh manure be used. Spread your fertilizer out about the plants, and then work it into the soil with spade or hoe.
You will doubtless find many seedling plants in the beds where they germinated last fall. These should be transplanted to places where they are to bloom as early in the spring as possible. All perennials that got a start last year will bloom this season, but those grown from seed sown this spring will not bloom until next year. Therefore make liberal use of self-sown plants.
We are generally in such a hurry to do garden work in spring that we begin it before the ground is in proper condition to make good work possible. If it is spaded up before the surplus water from early rains and melting snows has had a chance to drain out of it, no attempt should be made to pulverize it then. It simply will not pulverize, but the result of your attempt to make it do so will be a lot of lumps and chunks. But if left exposed to the disintegrating action of wind and sunshine and possible showers for a few days, it will be in a condition that will make it an easy matter to reduce it to fineness under the application of hoe or rake.
Plan your garden. Never trust to "the inspiration of the moment" in making it. Go over the ground and decide where you think this or that plant would be most effective. Make a diagram of it, locating each plant that you propose to make use of, and when seeding-time comes you will have something definite to work to. Haphazard gardening is never satisfactory.
