Certainly look as if they have not had anywhere near enough water. They are bog garden plants and do need a lot of moisture to thrive.

I made sure they were well watered when i bought them. I shall leave it and hope they perk up.

They need a constant supply of water to remain happy. Give it a good soaking now and every day for a while to see if it perks up.

The soil the one in the photo is in looks dry and also doesn't look as if it has much in the way of humus in it. As OwdB has already said they need a lot of moisture to thrive and do well in part shade rather than full sun.

Don't just leave it and hope that it perks up - it needs water - now!!

It looks like it may be planted a little too deep, too, but the main problem looks like lack of water--that soil is dust dry!

Thanks all for the comments on my primula denticulata. I moved them into a pot with good humus, they are already looking better. The thing is, I put bags of humus in the soil earlier in the spring but we haven't had any rain at all, I give them all a good soaking in the evening, but they are suffering in the heat and lack of rain. I have added extra humus around the plants in the sunny border, they all seem to be quite happy, but as I am such a novice I don't know how much humus is enough!

Keep your primulas in the shade to recover, in a pot they will dry out very quickly in the sun and wind (that is assuming you are having the strong winds we are).

Thanks for all the help. I have put them in my funny plastic greenhouse (which looks like the leaning tower of Pisa!) and they look much better, new shoots are pushing out already, so I haven't killed them, I have 5 lovely primula denticulata for next year! I didn't realise how much you need to water; now I give each one a good soaking for at least 10 seconds; it is time consuming but at least I won't be losing any plants! It is so dry and so windy now, the worst thing for any plant. Now I am learning how to be a gardener, the hard way!

I would suggest you get them out of the greenhouse and into a shaded area. Primulas do not like being in full sun they are woodland type plants and also need damp ground to grow well in. A 10 second soaking is not going to achieve anything in the long run, as you now have them in pots bung all of them into a container of water for a good fifteen minutes every few days, this way the soil is well wetted. Be careful though not to over soak and drown the plant.

Yes, I have had a few funerals for plants that I forgot, and left in the water overnight!
