Self Seeding

Question

I am putting down several inches of (cedar) mulch in my butterfly garden, as here in Dallas it gets up to 100 degrees F or more in August. I want to keep the moisture and protect the plants from the heat. Will this mulch prevent the self-seeding flowers from self-seeding? Or will the sprinkler system wash the seeds down into the mulch and allow them to sprout?

Answer 1

Self seeding flowers should still be able to sprout. The mulch breaks down over the course of the year and creates a good base for the seeds to grow in.
