In landscape beds and vegetable gardens, about 2 to 3 inches of mulch is usually enough, but go with composted wood chips, rather than fresh, or organic mulches. Mulch can also be used as a soil conditioner to help keep soil moisture levels in check.
How much dirt should you leave around a tree trunk?
Leaving 8-10 inches of bare ground around the trunk is a good rule of thumb. If you plan to add fill dirt to the area around a mature tree, make sure you don’t place it too close to the trunk.

Burying the base of a tree stops the vascular flow of water, oxygen and nutrients from getting to the rest of the tree. This makes the more susceptible to ailments, fungus, and pests over time. To properly mulch your tree, evenly spread mulch around the tree's base up to 4in deep.
Can you put topsoil around trees?
Nonetheless, you need to be cautioned against putting soil over tree root. Roots on the surface are actually covered with lenticels, which are gas exchanging structures. Tree roots need oxygen, and dumping a thick layer of dirt on them can suffocate them.
Is it OK to put gravel around a tree?
The majority of a tree's root system is within the top 6-24” inches of soil. So grading down to 6” and adding inorganic ground cover (e.g. plastic sheeting, gravel, decomposed granite) will remove the soil's organic layer and compact the soil, harming tree health.
What do you put around the base of a tree?

How do you landscape a tree with exposed roots?
Mulch or a wood byproduct is the quickest and easiest way to cover exposed tree roots. Rim the circumference of the tree with a three to five-inch high strip of edging or brick. Once in place, cover the roots with three to four inches of mulch or just enough to cover the roots.
How does raising soil level affect trees?
Raising soil level around a trees root flare is detrimentally identical to planting too deeply. Humans assumed trees produced Oxygen as a byproduct, but actually its an essential ingredient utilized by their root system just below ground. When these roots get smothered by Mulch or added soil, they act like drowning swimmers and immediately come up for air above obstruction. And just like disoriented swimmers, many times these rising roots end up growing toward trunk instead of radially away. If walled in like topics example, rather than dive below obstruction to get past it, roots will take easiest route and stay near oxygen supply while inevitably circling around trunk.
Why is the soil level around the base of a tree not raised?
However, because you've got a closed in 'well' around the base, it doesn't sound as if any soil there will be particularly free draining. The problem is because the soil may/will cause rot and fungal infections in the base of the trunk (which is supposed to be exposed to the air) because it is now buried. Infections like this at the base of a tree do cause plant death.

How much fill can you put around a tree?
Raising the Grade: Most young, vigorous trees can tolerate shallow fills of up to four inches if the fill is sandy. The same amount of clay fill, however, usually causes tree decline.

So what is considered a "small amount?" A 2-inch layer of soil is about right. Better yet, mix in some compost before applying the soil, so that the resulting mix will be lighter and fluffier, thereby reducing the likelihood of suffocating the roots. Sow grass seed over the area to try to keep the soil from washing away. If, a year or so later, you find that the soil did not hold (for whatever reason) and the roots are showing above-ground once again, repeat the procedure.
How to dress up under a tree?

How far should a deck be from a tree?
The inside perimeter of a deck built around a tree should be a minimum of two feet from the tree’s trunk to allow the trunk to grow, farther if you anticipate more growth. The inside border of a patio (because it’s solid and will block water and air) should be three to seven feet (or more) away from the tree to give the roots plenty of surface area to absorb water. Plants or rocks can be used to landscape the space nearer the trunk (see above).

Use either commercial mulch, such as pine straw or wood chips, or recycled dried leaves.
What plants grow under the tree trunk?

What tree has deep roots?
Trees including white oak and hickory send down deep roots, but others, such as maple and cypress, have roots just beneath the surface, or, in some cases, even extending above the ground.

If you run into a root, stop digging and select a different spot for the plant.
Why are my trees barren?
Blame thirsty roots that draw up all the water and heavy branches that prevent sunlight from reaching the soil, making it tough for other plants to thrive. Fortunately, with the tips ahead, you can transform those desolate spots, adding color, texture, and other design elements—while maintaining the health of the tree—to make your yard the envy of the neighborhood.
Do evergreen trees need sun?
Some trees, such as maples and magnolias, allow dappled sun through their boughs while others, including most evergreens, permit virtually no sunlight near their trunks. Before choosing plants, observe the amount of shade under the tree at different times of the day. Deep-shade plants such as ferns and hostas can thrive nearest the trunk, while semi-sun varieties like lily of the valley and coral bells can grow under the perimeter of the tree’s branches.
How high should a tree well be?
As a retainer around the trunk, an open-joint wall of shell, rock, masonry or brick in a circle around the tree trunk should be constructed with at least 1 to 2 feet between the trunk and the wall. The wall should be as high as the top of the new grade. The completed opening is commonly referred to as a tree well.
How much of the soil should be broken up?
The top 3 to 6 inches of the soil surface should be cultivated or broken up carefully so as to disturb the least possible amount of roots. This treatment allows better contact with the fill soil and prevents a sharp line of demarcation between the existing soil surface and the fill.
What happens when soil is placed over the root system?
When soil or any type of fill is placed over the existing root system, it causes a reduction in the oxygen supply to the tree roots and slows down the rate of gas exchange between the roots and the air in the soil pore space. Both oxygen and water are essential to the growth, development and nutrient uptake by the roots.
What to do after a tree fill?
Corrective Steps to Take After a Fill Was Made. If a fill has been in place long enough for visual symptoms of tree deterioration to occur, little can be done to save the tree. In cases where the fill has been made recently or where no serious damage has occurred, some corrective action can be taken.
How does lowering soil grade affect trees?
Unless corrective steps are taken immediately, lowering the grade exposes the existing root system to the air and reduces the supply of nutrients and moisture available to the roots. Raising the grade or soil level over existing roots can have an even greater effect on the future growth and survival of existing trees.
Why is careful consideration necessary for tree restoration?
Because there can be no assurance that a tree will recover from the damage already done, careful consideration must be given to the value of the tree in the landscape before expensive corrective measures are undertaken. The tree would have to be extremely attractive, valuable or have significant historical value to justify the expense of these corrective measures since success is not assured.

Can maple trees take inundation?
Many maple species can take periodic inundation, which is why yours hasn't perished.

Can trees survive in floodplains?
Tolerance of burial depends on species of tree and texture of soil. Some trees are able to survive quite a depth of dense soil being dumped on them all at once. As might be expected these tend to be those occurring on floodplains.
Can you put fill over a tree?
"Although there are reports of trees rooting into deep fill and surviving for long periods, placing fill over the trunks of trees is ill advised. Not only is exchange of gases disrupted, but many trees are subject to collar rot, which can occur if the trunk remains moist. A new root system develops in the fill, and the old system dies. The new root system may be adequate to keep the tree green and healthy, but asa the old root system decays, the stability of the tree is jeopardized." (pg 319)
