My bed of Dianthus Pinks have been blooming nicely for weeks.
Now all flowers are dead on 8 to 15 inch long stems. I cut off each dead
blossom but do not see any new buds. I don't plan on feeding them.

Can I shorten those long stems? Is there a special place to cut and
shorten each stem that will stimulate new buds and look less leggy? Any
web sites that show how to shorten the long stems and where to cut?
Google search was not very helpful.

Will these bloom during the summer or are they only Spring bloomers?

Thanks for hints. Dave_s
