## How to Identify and Fix Common Gardening Problems ?

We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :

First, use the following formula to determine how much fertilizer is needed to apply 0.5 pound N per 1,000 square feet to the turf: pounds of N per 1,000 square feet desired for application ÷ percent of N in fertilizer (in decimal form) = pounds of fertilizer per 1,000 square feet.
Spreader calibration consists of two processes. First, the spread pattern must be adjusted to distribute the fertilizer particles uniformly. Second, the amount of fertilizer spread over the desired area must be measured and adjusted, if necessary, to equal the recommended application rate.
To calibrate measurements from visible/NIR/SWIR channels, a gain parameter is derived from the pixel counts over the visible calibration target (the VISCAL unit) during the period when it is illuminated by the sun and the illumination level is constant – this occurs once per orbit.
The location of this setting varies depending on the device and Android version, but is typically at Text input can be found under Menu > Settings > Language & keyboard > Touch Input. Tap Calibration tool or under “Finger touch precision,” Reset the measurement.
If you are using a drop spreader, such as Scott`s Classic Drop Spreader, and using a Yard Mastery granular fertilizer, you will want to set your spreader at a 7.
The calibration correction is equal to the difference between the value displayed by the instrument during calibration, and the certified value of the standard.
One Way to Calibrate a Sprayer

Measure the distance in inches between spray nozzles on the boom. Calculate the desired nozzle output (ounces or gallons). Catch one minute`s worth of water from one or two nozzles at the operating pressure. Adjust the pump pressure or ground speed until the desired output is reached.

Place your spreader setting on a low setting (usually one-fourth of the spreader setting range or less). Spread the material over a 50 x 20-foot area (1,000 square feet). If there is material left over, increase your setting. If you come up short, decrease your setting.

How do you know that the Classic Drop Spreader is adjusted properly? i’m using too much fertilizer in comparison to my old Scotts drop spreader and leaving too many burn marks. I thought that the proper adjustment was determined by setting it to 6, open via the handle and checking the arrow on the bottom making sure it’s lining up with the adjustment line.Please advise. Very dissapointed with the new product.
ANSWER : I’m sorry to hear about the problems you are experiencing with your spreader. You’re right, this is the correct way to adjust the calibration of the Classic Drop Spreader. If you are still having problems, you can call Scotts at 877-465-5160, and we can assist you further. Hilary @ Scotts

The cable on my mum’s scotts evergreen drop spreader is not connected. Where can I find out how to reconnect it correctly?

My Scotts 3000 spreader has a spring that closes the drop chute and it has broken. Is there a replacement spring available?
ANSWER : You can use almost any spring with the same or close tension. Lowes and Home-Depot carry an assortment of springs.

I have an older scotts drop spreader, called a precision flow control model and do not know what settings to use with the Scotts turf builder I have purchased.
The best way is to just place a small amount… like 5 lb in the hopper…start with it barely open and see how far you get,,, then compute from there what you need…
The settings they give you are guesamates at best and are often set to place too much… why not??? they are selling you a product!!

I just bought a new Scott’s “Classic Drop” Spreader. I owned a Scott’s drop spreader before and the recommended settings on Scott’s fertilizer bags always worked great.

On Scott’s Turfbuilder fertilizer for Spring (yellow on bag) it recommends one setting for drop spreaders which was 5 3/4.

I drained an entire 14 lb bag with that setting before I was even 1/4 done with my lawn. Usually I can do my whole lawn and have some left over. I even returned the spreader to Home Depot and got another one and another bag of fertilizer and the same thing occured. I adjusted it down to 3 after a bit and still used the entire other 14 lb bag.

ANSWER : I am sorry that neither spreader performed as they should have. This is very concerning to us, and we would like to get more information about the spreaders, if you still have 1 the manufacture date would be most helpful to us. It sounds like you could possibly have an over-application of the product as well. If you could call us at 1-800-543-8873, we would be happy to discuss this with you. Stacey at Scotts.
