It’s not too late to plant perennials in our area. The first hard frost won’t arrive until mid-late October, so there’s plenty of time to get roots established before the cold sets in.

Because the sun and temperatures aren’t so hot, fall is an ideal time for planting perennials. The cooler weather means less stress for new plants. And weeds aren’t as active in the fall.

Tonkadale offers perennials that thrive in our area (Zone 4), and are hardy enough to survive our cold winters. For best results, be sure to prepare the soil to suit your new perennials and fertilize them after they’re planted. We recommend digging a hole twice the size of the root ball, mixing in planting mix or other organic material and planting the top of the root ball level with the ground. Our experts can help you determine what will work best in your garden.

All perennials, including newly planted perennials, need to be watered well until the first hard frost. This helps ensure winter survival.

Also, gardeners can cover newly planted or tender perennials with marsh hay after the first hard frost for some extra protection. Marsh hay, which Tonkadale Greenhouse sells by the bale in the fall, is a great material to use in the garden because it’s clean and free of chemicals and weeds. Grass clippings and leaves can also be used.

In addition to perennials, our Minnesota-hardy mums have arrived for fall and are for sale.

If Labor Day weekend is a good time for you to work on your garden, we’ll be open 8 a.m. to 6 p.m. Friday and Saturday, and from 10 a.m. to 5 p.m. on Sunday. However, we will be closed on Monday so our employees can celebrate the holiday with their families.

If you already have plans for the holiday weekend or can wait to plant, join us on Sept. 6 for Customer Appreciation Day. We’ll be serving free hot dogs and root beer floats from 11 a.m. to 2 p.m. that day. And perennials will be 50% off on Sept. 6 and 7, too.
