Further, older plants usually tolerate flooding better than younger plants. The bottom line is that plant response to flooding is highly variable. One exception is spring flower shrubs, such as lilac, which should be pruned right after they bloom. Be sure you know how to prune your plant before you start. Instead, prune to maintain the natural shape of the plant.
Fruit trees are an exception.
With them, thin out the top and center of the plant to let sunlight penetrate to the lower branches to form more flower buds and hence, more fruit. The issue of whether or not to use pruning dressing has been solved, I think. In general, DO NOT cover pruning wounds with wound dressing. Cuts will heal more quickly if they are not covered. Consider Ribes for fresh fruit this summer.
