how to save hydrangea ruined by foreclosure
I recently bought a home that has been in foreclosure for two years. The garden contains a number of smallish hydrangea plants that are nearly dead due to neglect. However, I can see they are fighting to live. Although they are mostly brown, each has a few green leaves and one has a very small smattering of pink blooms. I don't have enough leaf or bloom to determine the type of plant with certainty, but I think they may be Annabelles. If it helps, I live on the CA Coast (zone 10 I think) and these plants are plucky enough to have survived two years with no water other than rain and coastal moisture.
I would like to prune these largely brown plants and/or do whatever else is necessary to bring them back to their former glory. However, I have never had a garden and do not know the first thing about caring for flowering plants, so I need to proceed with caution. Before going at them with pruning shears, I thought I would seek advice.
Any thought on what I should do with these guys? Thanks.
