I live in Berlin, MD and have had a bush cover on my outdoor hardy gardenia for the winter months. Is it too soon to take that cover off? Last year, uncovered, I had a lot of dead foliage by Spring, thus my decision to have it covered this past winter. Thank you.
It is difficult to predict the weather. To be on the safe side, monitor until there are no frost predictions in your area. Then remove the cover. Here is a link to your average last frost date https://garden.org/apps/frost-dates/
