Hi, ! I don't know if this is the "scorch" that was talked about a few weeks ago, or what. I've got one good sized clump that has not done anything! It's green(kinda' yellowish, tho) except for the "brown tips, that every thing seems to have this year. It just refuses to grow new foliage. We moved the clump hear in the early summer of 2010. It seemed to take off ok, but didn't bloom in'11. Color has been a little off the whole time, so I've babied it a lot( bone meal, fert.,etc.) This year, clump seemed a little smaller, and even less healthy. Didn't bloom this spring, so I dug it out,cut the "old" material out ,trimed off the old, dead roots(seemed like there were a lot of them). Gave it a bleach dip, and replanted in new soil. This was 1st part of July. It has done nothing! Absolutly no new leaf growth. Fans are still that same yellowish green, but haven't "browned", or shriveled. Dug up one chunk yesterday to look, and there are new, white roots there (not as many as I think there should be). Rhisomes are nice and "sound". I had split up the clump, and planted some in another area ,and that looks the same. What do you think? Give it more time, or trash it? I'm sort of "gun shy" after reading all those "scorch" posts. Confused ...Thanks...Arlyn

If you like it and have the space and the rhizomes are healthy leave it and let it decide this fall and winter.

From what I've read, and heard, when you have scorch, the roots just kind of die off, and there are brown leaves in the center of the plant. You might just have a slow growing cultivar especially if the others around it are thriving. I agree with Dee, Just leave it alone a while, and see what happens.

I want to think that the Scorch was just part of our crazy weather we had this year, I have never seen it or anything like it before and hoping to never see it again. I would be surprised if you had something that had it and it lived through the winter what I had with it after a month there was no saving them they were gone, it has a real specific look to it and always the middle leaf is brown which gives it away that you have a problem and with scorch you will not need to dig it out just a light tug and the whole clump will come out of the ground. I'm sure your weather has been hot and dry like ours this year and it is really hard to get them to take when its over 100 degrees for multiple weeks I had sprinklers running for 3 hours a day to keep everything moist in July the extreme heat really seams to stunt the new growth in them.

Hi,! I've decided to "wait it out' and see. I'm sure there is something "wrong" with the plant, not just a slow grower, but darned if I can see what! When we moved, all the other clumps (about 50) did fine ,just this one is failing. And it's planted right among the others! Hope fully it will "snap to" and bloom next year!...thanks...Arlyn

Around our place, when we have one sickly plant in a row of otherwise healthy plants, we just shrug and say a skunk must have peed on that one.

many of the ones that I found had scorch in my gardens.. I dug and left lay on the lawn in the heat driven days of June and July. They were on a tarp actually.. I figured hopefully they would get enough heat to rid the plant of its ailment. They were all planted back at the end of July/first part of Aug. Some did not make it at all, but there are also some that are starting their new roots and even little tiny green leaves! Don't know if they will make it through the winter, but perhaps they will have a fighting chance.

I know I could have replaced these as they weren't the expensive ones, but in my heart they are worth way more as they came from friends. I'm stubborn that way I reckon.

I guess if it was me, I'd clean it up a little (like you did) and leave it. It'll either get better or die totally (at least that is my reasoning.)

I have about 20 Medians which border a flower bed that need to be dug and replanted this year but I've planted so many from orders and have moved so many of mine that I am burned out. Today I put a handful of alfalfa pellets around each clump and watered with some Miracle Grow. Hopefully this will stimulate them to grow and bloom well next year and then I will dig them, improve the soil, and replant.

I keep looking back at your planted iris to see how deep they are. I guess mine are OK .There is a small amount of dirt on the rizome, just enough to anchor the plant into the ground.

This is a shot of my "failure to thrive "iris. I noticed to day that on the uppermost rhisome in the pic, there is a small,deformed bloomy looking thing! not sure if it will get any larger so I thought i'd get a pic of it to show you!(i need the practice with the camera, and posting pics anyway!!)...ArlynThumb of 2012-10-15/crowrita1/257453
It's purple, real small, and hard to see in the photo. It's about 1/4" long.( if I knew how to add an arrow to the pic, i would----computor challenged!)

Maybe that will open to a full flower, LOL.

And nice pics, Arlyn! So glad you got that camera!
