![]() ![]() Insects also play important roles in breaking down material and aerating and rotating the soil. Bacteria and fungi can be essential in facilitating nutrient exchange with plants and in breaking down organic matter into a form that roots can absorb. It also plays host to significant bacterial, fungal and entomological activity without which soil quality would degrade and become less suitable for plants. There are generally a high concentration of roots in topsoil since this is where plants obtain most of their vital nutrients. Together these make a substrate capable of holding water and air which encourages biological activity. Topsoil is composed of mineral particles and organic matter and usually extends to a depth of 5-10 inches (13–25 cm). ![]() It has the highest concentration of organic matter and microorganisms and is where most of the Earth's biological soil activity occurs. Unwrap the burlap to view the true soil level on the trunk.Surface runoff of topsoil from a field in Iowa during a rain storm If buried to this level, the plant is in too deep. Roots must go below the soil and bark or the stem MUST be above the soil for success.ĭON’T BE FOOLED BY BURLAP!!! Often, burlap is wrapped up around the trunk. REMEMBER: Roots are roots, and bark is bark. Even a heavy mulch piled against the trunk or stem of a plant will cause poor growth or death of the plant. From marigolds to maple trees, proper planting depth is necessary. tomatoes) but 99% of the time it is a rule that must be obeyed. There are rare exceptions to this rule (i.e. The importance of maintaining proper planting depth relates to all planting and transplanting situations. This will collect water and direct it down over the root system below. This extra soil should be used to make a little dike or berm around the tree away from the stem. If the stem above the crown is covered with soil, it stops the plants ability to draw moisture and nutrients from the root system to the branches and leaves above. It has the same effect as burying the stem too deeply. What should we do with it? At this point, many will opt to get rid of it by piling it up around the stem of the plant. Since you have dug a hole and put something into it, there is dirt left over. This is the point at which inexperienced gardeners often make THE BIG MISTAKE. Peat moss exposed to the dry air on the surface will dry out and then act like a wick, drawing moisture from the soil below. This is important below the tree to provide needed moisture and lure the root system down. We use peat moss to improve the soil’s ability to retain moisture. The top 1/4 of the hole should be filled in with the original soil with NO peat moss added. Once this is done, finish planting by filling in the rest of the hole around the sides of the root ball. Add soil to the bottom of the hole, if necessary, to bring the crown (the crown is the dividing line on the plant between what is above the soil and the part below the soil) up to the PROPER PLANTING DEPTH. In other words, the tree’s trunk should NOT be sunk below the soil level of the surrounding area. When the tree is placed into the hole, the level of the soil on the trunk of the tree should match EXACTLY the level of the soil you are planting into. Once the soil at the bottom of the hole is compressed, place the tree into the hole the check for PROPER PLANTING DEPTH. This can be done by tamping or watering heavily. This soil should now be compressed before you place the tree into the hole. Your soil blend at the bottom of the hole is very loose because you have been mixing it. So far everything is being done properly. At the bottom of this hole you will mix peat moss and the original soil together in a 50/50 ratio.įor an average size tree or shrub you will mix about a cup of bone meal with the peat moss/soil blend at the bottom of your hole. If you are planting a tree, for instance, you will dig a hole about 1 1/2 times as deep as the height of the root ball on the tree you are planting. The mistake occurs at the final stage of the planting process. New gardeners very often will do a great job preparing the soil with bone meal, peat moss, and other additives necessary to insure growth and survival. Planting depth refers to how deep the plant has been sunk into the soil. What they fail to realize is the importance of proper planting depth. The most common mistake inexperienced gardeners make occurs when they are planting. ![]()
