I am just happy to have blooms this year. I have some deadheading to do lol left for 4 days and lots of blooms for almost end of Aug. I lost only 8 plants to root rot. ZERO losses to Voles / Moles this year so the 3 gallon sink pots worked perfect with 1/4 inch hardware cloth.
One thing I would change is pull more dirt up around almost like hilling potatoes, till they got established plants the heat from the black plastic had a few wilted but overall very pleased.
