Pale leaves on my Primroses

Why are the leaves on my primroses going a pale green. I bought the plants from a good source and they are basically still in good condition however some of the leaf is changing from a dark to light green. I have planted some in mixed pots and left some in their original containers however it happens to both. help would be much appreciated.

 

My guess would be either waterlogging or starvation. How long have you had them and have you fed them weekly or so? Is the soil/compost wet or dry to the touch? Remedy as appropriate!

 

yes it is usually the outer older leaves - I keep the soil damp and never let it dry out I also feed with organic Bio-Bloom at every watering.

 

As Marley Farley says - the outer leaves can yellow and die back, but I would still check the compost, as Michaelmasdaisy says, if wet, cut down on the watering. They really don't like it too moist and can rot. I would also cut back on the feeding after the initial boost. Fingers crossed they should be fine, they are generally tough little plants.

A friend gave me a tray full of wild primroses many years ago - and I carefully planted them under my appletrees, where the book said they should do well. They promptly migrated over the years to places where according to the book they should not have been happy. No primroses at all where I planted them :D

 

Most plant that we buy these days seem to be grown under ideal, but totally unnatural conditions. Therefore even something as hardy as primroses seem to need hardening off, to out door conditions. I'm only guessing but I reckon the yellowing of the leaves is due to the shock of being exposed to the weather.
