Can't keep this plant healthy

[Wendy_S]

I bought this plant to support the bees but it has dried up while it is supposed to bloom in this month.

I need to go outside for a picture first. (but it rains heavily)

Hi @Wendy_S,

Sorry to hear about your plant. Could you please try uploading your photo again so members can help identify it?

Thanks,

Jason

Here they are. My Delpiniums.

They are planted in a sunny area as instructed. They should be blooming in this period.

It has been very hot and dry recently but they started to deteriorate before that.

Any ideas?
