I purchased two rhododendrons about 1 month ago and for a variety of reasons they haven't been put in the ground yet. I've been keeping them watered, and they bloomed well and have a lot of new growth. Last week was lousy weather, and I didn't really water anything. Saturday I went out to water and the new growth (but not the old growth) on the rhodies were totally wilted.
I pressed the soil and one plant is totally root bound. Feels like a solid mass of roots. The other isn't as bad. I watered them well and then put the pots into 5 gallon buckets with some water in them and they perked back up.
These will hopefully get planted this week, and I am wondering what to do since they are so root bound? Do I just slash the sides of the root ball and hope for the best? Any suggestions are appreciated.
