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 :

The factors that keep draining your lawn mower battery include damaged, loose, or corroded cables, an electronic drain, or cables that are attached loosely. Sometimes, it is as simple as the battery needing some maintenance. Other plausible reasons are faulty alternators, voltage regulators, and battery chargers.
If your phone`s battery is draining faster than usual, it either means you`re using a lot of energy or your phone is not using energy efficiently. This could mean you`re overworking your phone by running too many applications, or something is physically wrong with the phone battery itself.
You Lose Power in the Middle of Mowing:

Here`s why this happens and what you can do: Dirty Air Filter on Your Lawn Mower: Clean or replace. Dirty Spark Plug: Clean or replace. Build Up of Clippings & Debris: Clean underside of your lawn mower deck as noted above.

Electric lawnmowers may cut out for two main reasons: A faulty power switch or a loose cable connection. An overheating motor can cause the thermal cut out to trip.
Riding lawn mowers use a battery to turn over the engine and power extra components such as headlights and electric clutches. Your mower also has its own charging system that recharges the battery when the engine is running.
A new lawn battery should last between three and five years. In order to achieve that, however, it`s important to perform regular maintenance. Here are a few tips to help you get the longest life possible out of your battery.
Loose, Dirty or Disconnected Spark Plug in Your Lawn Mower: Check it out, clean off debris, re-connect and tighten. Dirty Air Filter: Clean or replace. Fuel Not Reaching the Engine: Tap the side of the carburetor to help the flow of gas. If this doesn`t work, you might need a new fuel filter.
When a spark plug becomes fouled, the tips become coated with fuel, carbon, oil or dirt. This interference limits the ignition power needed for mowing on level or uphill surfaces. Maintain your spark plugs by changing them every season or regularly removing and cleaning the tips.
Listen for a Clicking Sound

Starting up your lawnmower can tell you a lot about its health. Grab the pull cord or turn the key in the ignition. If you hear a clicking sound, replacement batteries are probably in your future. The motor is trying to draw power from the battery, but it`s not receiving enough juice.

The symptoms of your lawn mower battery going bad include the engine not starting, the mower producing clicking noises and a rotten egg smell, the battery losing charge faster than normal, the mower refusing to cut grass, and poor fluid levels.
Considering lawn mowers tend to sit for months during the wintertime, it`s normal to expect a lawn mower battery to last three or four years.
Most manufacturers recommend charging your lawn mower battery at least once a month during the summer months and at least once a week during the winter months.
