Leaving the roots in works best in large pots/planters, and not so well in smaller pots. Especially down to cell pot size. Outdoors, in the ground, leaving the roots is better, because the soil microbes will digest the roots quickly, improving the soil.
What happens if you leave roots in soil?
If you do, you’ll be robbing your soil microbes of a good meal and degrading your long-term soil fertility. You’ll also be inadvertently removing a lot of the good microbes that live around the root systems of your old plants – microbes that could help your future plants.

Should I leave roots in the ground?
Roots should not be left in the soil that is to be reused as a potting medium in a plant pot because they will hamper the growth of new plants. In other cases such as open gardens and raised bed gardens roots can be left in the soil if the previous plants did not die because of a known disease.
Can I leave roots in potting soil?

How long does it take for roots to break down in soil?
This encourages the roots to deplete their resources quickly so that they begin decomposing faster. In most cases, allow four to five years for the root system to decay before you plant another tree on the ground that was beneath the foliage of the old tree.
Should you remove old soil when repotting?
Remove about one-third or more of the old potting mix surrounding the plant’s roots. As it grew, your plant removed some or all of the nutrients in the current mix, so you’ll want to give it fresh potting mix or soil.
Should I remove old tree roots before planting?
Before planting a new tree where one was removed, make sure get rid of all the roots and old plant material. If any is left behind, nitrogen in the soil may be diminished or depleted, and saplings need an adequate supply of nitrogen for healthy growth.

Once plants are established, the green or woody part of the plant can grow directly from the fibrous roots below, and often, the plant stem can produce new roots. Root tubers found in some plants can develop buds that will produce new plants.
Do I need to change potting soil every year?

Should you break up roots when repotting?
To promote good nutrient absorption, trim the roots and loosen up the root ball before replanting. Use a sharp knife or pruning shears for this job, removing as much as the bottom third of the root ball if necessary. Don’t be surprised if what you cut off is a thick tangle of root tissue.
Will dead tree roots decompose?
There are several reasons you do not want to leave the stump in your yard to decompose naturally: After a tree is cut down, its roots will soon stop growing and eventually decompose in the soil. As the roots decay, cavities will be created resulting in soft spots in the ground.

How long do old roots take to decompose?
It can take three years or more for old tree roots to decompose. Even when an effort is made to remove the stump and old roots, a large amount is left behind, both below and on the surface of the soil. This material temporarily robs nitrogen from the surrounding soil, which can inhibit the new tree’s growth.
Should you till your garden every year?

Should you water plants right after repotting?
Plants may appear wilted and thirsty, but take care to refrain from watering until about a week after re-potting to ensure that any roots damaged during re-potting have healed. During the recovery period, place plants in a cooler, shadier spot. Most potting soil contains fertilizer.
How do I know when it’s time to repot a plant?
If the roots are circling around the rootball or are so dense that it is difficult to see any potting mix in the bottom third of the root ball, it’s time to repot. When you discover that your houseplant is pot-bound, you have a few options.
