What To Do in the Spring to Keep Your Trees and Lawns Healthy?

Every spring differs depending on the snow and rainfall Denver gets between March and May. Periodically, we get hit by a polar plunge in April which means all that early spring growth on trees and shrubs needs to start over again, if not outright killed by the hard freeze. Spring tree care kicks into gear because trees start to grow. As the weather warms up, yard insect pests and diseases become active, too. Wet springs support large infestations of many insects listed in Ross Tree’s insect calendar. Dry springs mean less tree insect activity and more landscape watering. Need spring tree care?

Spring tree care is about preparing residential and commercial properties for the hot, dry weather coming in the summer. They include lawn fertilization, deep root watering and fertilization, tree and lawn insect control, and tree trimming. Ross Tree’s General Manager discusses spring tree care issues in the video above.

Tree Trimming

Spring is a great time to prune out winter kill or storm damage. Structural training creates a dominant leader with subordinate side branches and secondary limbs. Trees with great structure can withstand Denver’s late spring snow and wind storms. Click here to view Ross Tree’s Standards-Based Tree Pruning Handbook.

Tree Insect Control

Well-watered, fertilized, and pruned trees fend off attacks by most pests besides the Emerald Ash Borer (EAB). Ross Tree was the first tree company in Denver to offer tree injections, ensuring that only the tree gets the product, not the surrounding environment. Our tree insect calendar helps homeowners identify insects on their trees in the spring.

Deep Root Feeding

If Denver experienced a winter drought, yard trees would benefit from supplemental watering and fertilization. A healthy root system sustains trees when the weather turns hot in the summer.

Lawn Fertilizing

The first fertilization of the year should boost grass growth but also slow the emergence of crabgrass. A healthy lawn lays the foundation for the grass to flourish when the weather gets hot and dry. Click here to find out more about Ross Tree’s lawn care programs.

Turf Mites

Turf mites thrive when Denver has late winter droughts followed by a dry spring. South and west-facing lawn areas dry out faster and encourage the growth of lawn mites. When mite levels are high and moisture levels are low, large brown patches occur that look burnt. Lawn miticide treatments and supplemental watering will help minimize damage from these invertebrates.
