5 Idiot-Proof Tips to Keep Grass Growing Under Trees
- Improve sunlight! Intensity and duration of quality light reaching the grass plant is important. The more time the grass plant has in full sunlight, the better it will perform. Pruning lower branches to raise the canopy will increase full sun exposure and allow more wind circulation helping to reduce humid conditions that can stimulate turf disease. Shaded areas with restricted air movement may require treatment with Fungus Fighters to maintain a healthy turf.
- Traffic Management! Shade stressed grass plants are less tolerant of heavy wear. Traffic management may be required. Active dog runs along shaded fence areas may require physical barriers to alter their traffic patterns. A runway of mulch along the fence could be your best option for large active canines.
- Use the Best Grass Seed! Uncle’s Premium Shade grass seed is the ideal blend of elite grass seed varieties with lower water and nutrient requirements showing improved shade tolerance and increased disease resistance. Reseed shady areas three times a year (spring, summer, and fall) rotating youthful, vigorous, low light tolerant grass plants into the maturing turf stand.
- Deep Water Shade Areas! In the spring, with frequent rains, the shade tree and grass are good neighbors, plenty of moisture for everyone. However, when spring rains stop and summer heat sets in, the trees get very unfriendly. A large shade tree can use hundreds of gallons of water a day leaving very little moisture for turf grass. Discourage turf disease in summer with heavy but infrequent waterings to reduce wet foliage.
- Release Compaction! Condition the soil under your shade trees. Increase the soils water holding capacity and improve drainage by core aerating and raking PrimeraFC field conditioner into the aeration holes. PrimeraFC is a natural porous ceramic granule having incredible air and water holding capacity. PrimeraFC helps to relieve compaction and improve drainage when incorporated into the soil
What about large tree roots?
Unchecked over the years, soil erosion, can expose shallow tree roots. Bare soil erodes quickly with no grass roots to hold soil in place. Top soil can be hauled in to cover exposed roots, but too much soils can be damaging for the tree. Gasses must pass from the air to the roots and from the roots back to the air. Too much, soil pack can create real problems for the tree so, be careful! Some surface roots can also be removed. Large surface roots are more for anchorage and with expert help, you may be able to remove a few. Always contact an arborist for advice on removing tree roots.
If all else fails, start a shade garden. Hosta, astilbe, hydrangea love the shade.
