The pruning season for many woody plants has been especially difficult to determine this year as the temperatures have swung wildly between frigid and too warm for pruning certain species.

This is the first confirmation of late blight on tomato or potato in Wisconsin for 2024. Originally the late blight was thought to be a possible sunscald as the symptoms on tomato […]
‘Native’ is a bit of a slippery term, though you hear it used on a regular basis in reference to plants. But the question is, “Native in reference to where?”.

So many things are flowering that I had trouble choosing what to cover. I decided that I would focus on ‘daisies’ since we have several cultivars (this word is […]

If you are feeling a bit of weather whiplash, you are not alone. Some plants have leafed out or are blooming a few weeks earlier than usual due to the record-breaking warm weather in February and early March. Now, Mother Nature as she often does, is doing a bit of a course correction and we […]
The 3rd-4th week in March is a great time to start seeds in the southern half of the state. We are holding a seed starting workshop this Saturday at the Dane County Extension office. This in-person event begins with a lecture on seed starting techniques and principles followed by a hands-on session in the Dane County Extension Teaching Garden Greenhouse where attendees can practice planting seeds and will take home some seeds in packs that they have planted. There are still spaces left if you’d like to come.
