What's eaten my primroses?

Hi all now most of you will know of the huge bargains I had late last year from B&Q 24 plants for a tenner etc.

Now I planted loads in my front garden of which are growing and flowering like crazy but the others I planted in the side garden amongst my bark chippings have all been eaten except the flowers, even on my soil borders hardly anything has been left....any idea's what has happened?

I did find a very fat green caterpillar among my pots there (didn't look like it has eaten anything it the pot just looked like he was in hiding) but not any on the chippings....could he be the bad guy? Hel.xxx.

 

Helen, do you have rabbits in the area?

 

Slugs have remained active over most of winter Hel.

 

How did the caterpillar get fat [smile] I found one amongst my plants last week Hel I and a lot of damage had been done even in this cold weather you would not think so with it being so cold

 

Slugs I rekon or pidgeons

 

Are they yellow? The yellow flowers never survive in my garden, I think it's the blackbirds. They leave the red ones alone!
