How does one figure how much actual nitrogen that can be applied as a fertilizer. The package directions are never very clear. Fertilizing a lawn must be easier than it seems!
Warm season grasses require 0.5 to 1 pound of actual nitrogen per growing month. An example of a warm season grass would be Bermuda grass.
Cool season grasses will perform well receiving 4-6 pounds of actual nitrogen per year. Examples of cool season grasses would be Kentucky Bluegrass, Tall Fescue, Bonzai and Red Fescue.
Here is a simple formula to calculate the amount of material from any given fertilizer: divide the number of pounds of actual nitrogen needed by percentage of nitrogen specified on the fertilizer bag.
For example, to apply 1 pound of actual nitrogen to a lawn using 16-8-8 fertilizer, divide 1 by 16 percent, which gives 6.25 pounds of fertilizer needed.
After the first rains of the year we seemed to get an unusual amount of mushrooms in our front yard. The first variety was the white one and now the brownish ones have started to break through the ground. The area in question is enclosed in the drive around driveway and the two side front yards don’t show any signs of mushrooms, nor does the backyard.
Mushroom growth is very normal after the first rains. It is an indication of an underground presence of decaying organic matter, such as old tree roots, stumps, wood from previous construction, etc. Perhaps you have some old pieces of wood left behind when the driveway concrete was poured or remaining roots of trees that once grew in that area… just a couple of ideas for consideration.
Most mushrooms cause no damage unless they prevent water from penetrating the soil.
There is no effective chemical control for mushrooms. Simply remove them with a rake or lawnmower and discard.
Don’t know where you sprayed Roundup or other pesticides? A blue colorant called Turf Mark lets you know where you are spraying and prevents skips and overlaps. Once applied, it dissipates in sunlight. Simply add the colorant to your spray solution.
