the general "rule of thumb" in horticulture for seed sowing - the seed should be covered to double depth the diameter of the seed - no more.
Some seeds however, should not be covered for germination - these are normally very fine seed such as Begonia
Hydrogen bonds hold water molecules far apart from each other. These bonds form between the hydrogen atom of one water molecule and the oxygen atom of another water molecule, creating a strong force that keeps the molecules separate. This gives water its unique properties such as high surface tension and cohesion.
The bonds that hold water molecules far apart from each other are ice. The hydrogen bonds' postulation in ice keeps them far apart from one another.
Electron pairs are kept as far apart as possible as molecules adjust their shapes according to the VSEPR (Valence Shell Electron Pair Repulsion) theory. This theory helps predict the geometry of molecules by minimizing the repulsion between electron pairs in the molecule's valence shell.
Gases, such as those found in the atmosphere, have particles (atoms or molecules) that are far apart from each other but are electrically neutral. Due to their distance and random motion, there is limited interaction between gas particles in comparison to solids or liquids.
If the particles of matter that make up a substance are relatively far apart and can move freely, the substance is likely in a gaseous state. Gas particles have a lot of space between them and move independently of one another.
Green beans should be planted about 4-6 inches apart to ensure optimal growth and yield.
Arborvitae should be planted about 3 to 4 feet apart for optimal privacy.
Hydrangeas should be planted about 3 to 5 feet apart to create a hedge.
Sweet corn should be planted about 12-18 inches apart in rows that are spaced about 30-36 inches apart.
Some plants can be planted close together and others must be farther apart. When you plant seeds, the package will tell you how far apart the plants should be. When you plant live plants, there should be a tag that tells you how far apart the plants should be.
Sunflower seedlings should be planted about 12 to 18 inches apart to allow enough space for them to grow and thrive.
Arborvitae should be planted about 3 to 6 feet apart to ensure proper growth and spacing.
Artichokes should be planted about 3-4 feet apart to ensure optimal growth and yield.
Blueberries should be planted about 4-6 feet apart to ensure optimal growth and yield.
Pine trees should be planted about 10-15 feet apart to achieve optimal privacy.
Raspberries should be planted about 2-3 feet apart to ensure optimal growth and yield.
Roses should be planted about 18-24 inches apart to ensure optimal growth and blooming.
