Most soil in Kern County has either clay, hardpan, or sandy loam and contains very little organic material. Tilling in organic matter adds great micronutrients to the soil, benefiting it for up to a decade. After receiving the results of your soil sample, add all amendments necessary.
To get an even spread, we suggest using a hand held spreader, do not spread it by hand (unless you are spot seeding).
When planting a lawn we suggest using 7-20-20 fertilizer when planting a new lawn. This fertilizer encourages root growth and over-all health for your lawn and other plants.
If this is a bare dirt area use the back side of a leaf rake and go over the area. This mixes the seed and the soil together. When mixing the soil and seed, make sure that the seed does not go deeper than 1/8th of an inch into the soil. The entire area should be packed with a water roller. If seed is just on top of the soil it has a very high mortality rate. If you are planting over a dead lawn, use a spiker aerator to push the seed down through any grass so that it is touching the soil.

Trees need special treatment when they are fertilized and watered because their root structures are so deep in the ground. It can be a challenge to get fertilizer and water to the roots because 75% of the fertilizer will only go about one inch deep into the soil. Merely spreading the fertilizer on the top of the ground does little good. In fact, it can encourage the tree roots to come to the surface.
To properly feed and water trees, two different types of holes should be made around the drip line of the tree. One hole is for fertilizer the other for pea gravel. The fertilizer hole should be 12 inches deep and filled to within four inches of the top. The remaining four inches should be filled back with dirt. The other holes are to be filled with pea gravel all the way to the top leaving only 1-2” to be filled with dirt. These holes should be 24 inches deep or more. Again these holes should be made around the drip line of the tree, with each hole alternating between the fertilizer and gravel. The holes should be about one to two feet apart, depending on the size of the tree (see illustration).
Doing this ensures that fertilizer is at the correct depth for the feeder roots and the gravel gives proper drainage and aeration to encourage a healthy root system. Using the proper fertilizer is also important. We suggest the use of our custom blended “SUPER 10 ”.
CITRUS TREES- need frequent fertilization because they lack the ability to store nitrogen. Three to four times per year is suggested for them.
YOUNG TREES – because they have a small drip line usually require three to four holes each of fertilizer and gravel are sufficient.
