Both black ash and white ash leaf out much later than most other trees and are now easy to spot. The flattened, tan-colored bark on many ash trees sometimes makes them look like they have a bad case of mange. But this condition is caused by a fungus that just feeds on dead bark and does no harm.

The leaves of sugar maple seedlings don’t look at all like maple leaves. They have no lobes or very small lobes at best. You can see the seed leaves, the cotyledons, below. Last year’s seedlings are very small but they have maple shaped leaves – and no cotyledons. Plenty of both this year.
If you’re working outdoors in the heat of the day, consider taking some switchel with you: roughly three cups of cider vinegar in ¾ of a gallon of water, plus some honey and some ginger. Cider vinegar supplies potassium and the ginger helps potassium absorption. Honey both revives your energy and reduces the tartness. Variations of this concoction have been used by farm workers since before the Civil War.
Most of us have heard that the CO2 level in Earth’s atmosphere today is higher than it’s been in a million years, but a new study, published in Geology, concludes that there’s now more CO2 than there has been in the past 23 million years. Something to think about while we fan ourselves.
