| THE CASUAL GARDENER, Shawna Coronado Heaving After New Years! = = = = = = = = = Dear Casual Gardener, It looks like something has gotten in my perennial bed and pushed up all my plants? What’s up with that and how do I get rid of that varmint? Signed, Vexed About Varmints = = = = = = = = = = Dear Vexed, My theory is it’s not a varmint at all, Vexed! Sounds like you are suffering from heaving to me. And no, I’m not describing that unfortunate situation which happens the day after you drink too much champagne! Heaving is a condition which refers to “ground heaving” and it occurs when the soil is alternately frozen and thawed repeatedly through autumn, winter, and spring. The preventative solution is proper mulching. You should have at least two inches of mulch on your perennial beds and it will: 1) reduce moisture loss in summer by twenty-one percent, 2) reduce the upper four inches of soil temperature [in summer], by ten degrees F and, 3) delay soil temperature in winter from reaching the freezing temperature by two days compared to unmulched soil. Mulching is good for your garden and will help prevent heaving. Particularly from New Year’s Day until early spring, the freezing and thawing cycle can result in plant heaving and subsequent loss of the exposed plant roots and crowns, so it is important for you, as soon as you notice the condition, to get the plants back in the ground. Plants can be pushed down by stepping on the plant very gently. You can also add soil to cover exposed roots if the ground is too frozen, temporarily correcting the problem until you can get out in warmer weather to more permanently fix the situation. Let’s all toast to proper mulching! Happy New Year! Please send your gardening questions for Shawna Coronado, The Casual Gardener to dearshawna@thecasualgardener.com or The Casual Gardener, P.O.
