Tree planting

When working in the landscape it’s common to find a surprising treasure – a healthy little tree. Usually, they were planted by squirrels or birds so aren’t in an ideal location, but it is possible to relocate and grow them into large shade trees. First, consider which seedling trees are worth saving.

Choosing the Right Trees - Good Guys vs. Bad Guys
Not all trees are equally beneficial to the landscape. Avoid saving trees with any of these qualities.

Planting depth was not recognized as a major tree health problem until recent years. But foresters and nurserymen now know that if a tree's root system is buried too deeply in the soil overall root growth is reduced and tree health, for the rest of that tree's life, is compromised.

Now that trees have dropped their leaves, and fall leaf coloration is done, one of my favorite sights for late fall and winter is a crabapple tree loaded with fruit. Maybe it’s just that the leaves are gone and the fruits are easier to see, but it seems to me that some crabapples develop deeper, more intense coloration after a few light frosts. My favorites are trees covered with hundreds of small, colorful fruits.

Fall is the best time of year to plant new trees, from early September through late October. Fall's cooler temperatures and increased rain allow trees to establish their root systems quickly, giving them a jump-start on spring growth. Tree root growth continues late in fall, until soil temperatures drop below 40°F.

But growing healthy trees, that will provide beauty, shade and wind protection for your property long-term, means getting them off to a good start by avoiding common problems at planting.

Stem girdling roots (SGR) are serious problems for trees. They slowly kill trees as roots grow in diameter and compress the trunk. Affected trees grow slowly, are often stunted, and are much more susceptible to secondary stressors like drought.  They often have scorched leaves when summer conditions are hot and dry.
