Another tip: you can root the cosmo cuttings. They root easily in water or just stick them back in the dirt. Love them🌼

I planted 3 seedlings on my lemon plant and they are doing great so I'll wait a bit longer and then transplant them on the patio, hopefully, they'll do well!

I grew cosmos for the first time this year. Put the seeds in the ground later April. Now I have these massive cosmos bushes. Still haven't had any flowers come out and don't even see signs of buds.

I am finding lacewing eggs in the garden since planting these, evidently the foliage gives them good concealment.
