We have several of what we think are Hawthorne Shrubs. (They have berries and when in bloon small white flowers with green leaves) They were cut back this Spring, and have not looked well at atl all summer long. I believe they were cut back too much. they are beginning to show improvement. However,they look anemic. What fertalizer should we use, and when can we fertalize them.

Our general recommendation is to prune only slightly - never removing more than one third of the shrub in any one pruning session. So, if your Hawthorns were quite overgrown, it would have been less stressful for your plants if you reduced their size over a 2-3 year period, pruning once each spring for as many springs as it takes to reduce their sizes. With that said, it sounds as though your shrubs are beginning to recover from the over-zealous pruning session. You can feed lightly when the weather cools - late October or early November and feed lightly again in the spring. I'd use a slow release 10-10-10 or similar fertilizer in amounts as recommended on the label for the sizes of your shrubs. Best wishes with your landscape.
