water or not part 2
Didn't want to hijack "water or not" part 1, but I have a similar question:
I planted a Lee's Dark Rhodo about 1 month ago. It was coming into bloom but the blooms were wilting. Someone (possibly rhodyman--my apologies if it's mispelled) suggested deep watering. I followed the advice and sure enough, the blooms picked right up.
Since then, the new growth (but not old growth) wilts almost daily. I supply deep watering and it perks right up. This has been happening several times a week.
It faces the east and gets morning sun. While we have had some warm days in the last few weeks (low 80's but with low humidity and very little rain), it has not been hot and the plant does not get the hot afternoon sun.
I have very heavy clay soil and amended the potting hole at planting to improve the drainage. Is it possible that the drainage is now too good? I had also created some holes in the root ball which I fill with water, which really seems to quench it's thirst until the next day. My dilemna is my paranoia: I have lost several rhodos in the past (ramapos and PJMs) from what I suspect is root rot caused by poor drainage. While I am more than happy to keep watering this one if that's what it needs, I'm afraid of encouraging rot.
As an aside: at a local (large, very reputable) nursery this weekend, all of their Lee's Dark Rhodos were also wilting. Is this a unique characteristic of this cultivar?
