How to Calibrate a Spreader
  1. Determine the amount of fertilizer needed for 100 sq. ft. For example, the fertilizer bag weighs 25 lbs. and covers 5,000 sq.
  2. Place this amount in the spreader.
  3. Mark off the area. For a rotary spreader, use a 10-foot by 10-foot area (100 sq. ft).
  4. Apply using the suggested setting.

How much should a spreader overlap?

Overlapping 2 to 3 inches should be sufficient with a drop spreader. With a rotary spreader, overlap the pattern one-quarter to one-third of its width. For an irregular shaped lawn, apply a header strip completely around its edge. Then, move back and forth across the lawn.

What setting on spreader for pre emergent?

For pre-emergent herbicides, put the setting on or a notch above one quarter. (If there are 20 notches, 5-6 would be the setting.) On hand-held spreaders, if there are 5 or fewer settings lower the setting to 3, or even 2. If a hand-held spreader has 10 or more settings, put the setting on or a notch above one quarter.

What happens if you apply pre-emergent too early?

If applied too early, preemergent herbicides can get washed away by rain or be washed too deeply into the soil, rendering them ineffective. If applied too late, their enzymes don’t properly work, and the weeds will grow up anyway. That’s why it’s important to watch the temperature and know exactly when to apply them.

What time of day should I apply pre-emergent?

The best time to apply is the when the daytime highs drop to the mid-70s for about three to five days in a row. Since a pre-emergent application will not last through the following summer, make a pre-emergent application late spring or early summer (see Spring Herbicide Application map).

Is it OK if it rains after applying pre-emergent?

How will rain affect the pre-emergent that was applied to my lawn? That’s a good question. A lot of people think rain will wash away our products and make them ineffective, but this is simply not true. Actually, rain makes our lawn treatments work much better.

Is February too late for pre-emergent?

Apply pre-emergent herbicides between February 15th and March 1st to kill spring weeds before you even see them sprouting. Any later than that window, and it’s probably too late to kill weeds with a pre-emergent herbicide (you’ll need to switch to a post-emergent to apply directly to the weeds).

Can I put down pre-emergent in January?

Many pre-emergent products will allow you to make heavier product applications to get more extended control. I like to apply at a heavier rate in late January so the product will last through March and prevent crabgrass seeds from germinating.

Should I mow before pre-emergent?

Since pre-emergent herbicide must be washed into the soil to be effective, you can mow before applying it, however you should wait a few days after application to mow again.
