If all leaves are pale, it is probably iron deficiency. I use Ironite to remedy this. The good thing - you can see the result within one week of treatment.

Both Iron and Magnesium deficiencies (Chlorosis) cause the leaves to pale with the veins staying dark. Mostly on the new growth.

If overall leaf is pale then Nitrogen is the likely culprit as far as deficiency goes.

Right, and if the leaf size is smaller than usual with its edges rolled downwards, it could also be a Sulphur deficiency. Ironite plus contains Iron and secondary and micronutrients and works very well for my Clematis to cure Chlorosis.

Hi Bk!

I don't come to the Clematis Forum to often and stopped by tonight to find out about transplanting. I saw your post and if you don't mind my adding, three or four years ago one of my Jackomani wasn't doing to well either.

I asked a co-worker who had one and he said he remembered his mother using banana peels. So I saved two or three cut them up into small pieces worked them in the soil and voila within a few days the green color returned.

As I was told it was the potassium although I could be wrong. All I know is it worked. I have a friend who works in a school cafeteria and when bananas are on the menu I get the peels (two or three good size cartons full) and they go right in my compost pile and eventually into my garden flowers and vegetables.

I even dry some peels out that I buy, put them in a large jar with a lid and occasionall sprinkle some around my Clematis plants and work into the soil.

Hope this has helped. Good Luck!
Jim
