Trees in Your Yard

... foot traffic close to trees can compact the soil over shallow roots, harming the root system and the trees health.
Compacted soil is not easily penetrated by water and air, the two basic needs for strong, healthy roots. Soil compaction can be caused by heavy equipment used near a tree, concrete over the root zone, even foot traffic can cause soil compaction. Do not store items by the tree.
Pruning and thinning of dead, injured, and crowded limbs is a definite "do". Good tree health requires air to be able to circulate between tree limbs and branches. When pruning, remember that a well-trimmed tree does not look like it has just been trimmed. While some pruning, as necessary, can be done at any time, major trims should be done in late winter or early spring.
For poorly draining soil areas, aeration is necessary around trees, an adequate supply of oxygen and water to the roots is essential. You can help aeration by drilling holes around the root zone and fill them with grave.
Of course, the essential element of good tree case is watering. Climate and soil type, and well as the needs of the particular tree, determine the amount of watering that needs to be done, but as general principles, water must be allowed to soak deep into the ground, and the most beneficial time to water is in the early morning.
Fertilizing is beneficial to increase growth, reduce susceptibility to certain diseases and pests, and can help reverse declining tree health.
