They can become less floriferous if overcrowded, though nobody has told
our local wild primroses that, thank goodness! That's why you read the
advice on dividing them and of course, it increases your stock of a
particular plant. Don't take off the leaves because they're what nourish
the roots of the plant. If you find you have too many, you could wait
for them to finish flowering, then dig them up and pot them. Then you
could either give them to friends or to local fairs and fetes for plant
stalls.

I agree entirely with Sacha, but would add that Primula Leaf Spot is now a
persistent problem with most of the primula tribe. This causes leaf
yellowing, but the spotting is usually evident. If you see leaves marked in
this way, it would be worth while removing them. If the leaf spot is left
unchecked, it generally weakens the plant - even our robust native primrose.

ok - many thanks to you and Sacha for the overview.

I'll keep a lookout for the leaf-spot.

What is the normal life-cycle of the leaf from now on - what should I
expect? Do the green leaves, if healthy, remain from now until next
spring.
A little off topic, however I have 2 clumps of wild primroses that
appeared in my garden. I was hoping that last year they would spread by
seeding but have not done so. Can I successfully lift and divide them,
without losing them? If so when would be the best time please?
