Common Questions About Trees How can I tell if I’ve picked a site with good drainage? Start by digging a hole as deep as your planting hole. Fill the hole with water and watch to see how water drains from the hole. If it drains at a rate of less than 1 inch per hour, pick a new site. If that’s not possible, consider installing some form of drainage to carry water away from the base of the tree. Also consider using water-tolerant species, such as: Red maple Sycamore willow oak river birch How big should the planting hole be? While you might be tempted to dig a very deep hole, in fact a tree requires a shallow planting hole that is no deeper than the root ball. However, it is very important to make sure the hole is wide enough. As a general rule, make yours three times as wide as the root ball. Such a wide shallow hole encourages the horizontal root growth that allows your tree to thrive. Should I add anything to the soil? You may be accustomed to backfilling planting holes with peat moss or other organic matter when installing perennials. When planting a tree, however, you should fill the planting hole with the unamended soil (that is, soil to which nothing has been added). This ensures that the soil around the root ball has the same density as the soil the roots will encounter later, as they spread beyond the original planting hole. A marked difference in density between the planting hole and the surrounding area can limit growth. Do I have to do anything to the tree before planting? All trees sold at Long Meadow Gardens come with roots wrapped in untreated burlap, which will degrade quickly in the soil after planting. To plant a tree wrapped in untreated burlap: 1. Remove any tags from the trunk and branches. 2. Place the entire root ball, including the burlap, into the planting hole. 3. Untie the twine from the base of the tree. 4. Push the burlap down to the bottom of the plan... Free Essays on Microsoft Apps Free Essays on Microsoft Apps Common Questions About Trees How can I tell if I’ve picked a site with good drainage?

The Definition of Atomic Mass or Weight in Chemistry

The Definition of Atomic Mass or Weight in Chemistry Atomic Mass or Weight Definition Atomic mass, which is also known as atomic weight, is the average mass of atoms of an element, calculated using the relative abundance of isotopes in a naturally-occurring element. Atomic mass indicates the size of an atom. Although technically the mass is the sum of the mass of all the protons, neutrons, and electrons in an atom, the mass of an electron is so much less than that of the other particles, that mass is simply that of the nucleus (protons and neutrons). Examples of Atomic Mass The atomic mass of carbon is 12.011. Most carbon atoms consist of six protons and six neutrons.The atomic mass of hydrogen is 1.0079. Hydrogen (atomic number 1) is the element that has the lowest atomic mass. The most common isotope of hydrogen is protium, an atom that consists of a proton or a proton and an electron. Because of a small amount of deuterium (one proton and one neutron) and tritium (one proton and two neutrons), the atomic mass of hydrogen is slightly higher than 1. How To Calculate Atomic Mass
