I bought Thalia and was told to plant bulbs now. I did. I subsequently bought some more Thalia and the nursery employee told me to plant them after the first frost (we have not had one yet). The nursery further instructed me to dig up the Thalia I already planted because the "soil it still too warm". They feared that the planted bulbs mights sprout leave and then freeze. So, what to do? Pull up and replant later in the fall? Leave the planted bulbs? Thank you.

Hi Extension folks, Our yard has tree cover (pecan, magnolia, poplar, maple) with a bit of sun mid-day to afternoon. It's a bit muddy at the moment and I'd like to establish some ground cover, especially pollinator (hummingbird) friendly stuff. A bit of Monkey grass and violets are present in patches. TIA!

I have noticed that quite a few shrubs etc at the Mn Arboretum are rated as zone 5. I would like to know what techniques the Arb does to have such a good success with these plants.
