TIPS FOR TOPGRAFTS & TREE-FORMED SHRUBS Topgrafted shrubs should be pruned on an annual basis with a focus on keeping the topgraft rounded and neat. Pruning the topgraft must be done with recognition of its effect on flower development. In the case of lilac, it is best to prune immediately after flowering so as to allow next years blooms to develop. It is also critical to remove leafy shoots that arise from along the interstem and at its base. These sprouts and suckers can quickly overpower the topgrafted shrub, destroying the beauty of the grafted cultivar. An alternative to topgrafted shrubs are tree-formed shrubs. Tree-form shrubs are produced by training up and retaining a single dominant stem for shrub cultivars. With a tree-formed shrub there is still the need for removing lateral sprouts and basal shoots.
