coreopsis deadheading and self sow seeding
I'm new to this forum and found it great help. I have additional questions, though.
I have approx. 50 Jethro Tull coreopsis. Many places say that these coreopsis self sow but bloom is extended if deadheaded..
so here's my question;
1. I've been taking shears and cutting off the "dead" blooms but I leave them on the ground..not picking them up...will it allow for "self-sowing"?
The reason why i just leave it is becasue there's just so many plants and blooms to go around picking up the dead blooms on the bed.
2. If it does'st allow for self-sowing, how do it get the plants to self-sow for next spring..do i just leave the dead blooms on throughout the winter and they'll just self seed and multiple themselves in the spring? I would believe it looks "ugly" or deers will eat the vegetation anywayin the winter..no?
Thanks so much
