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 :

Most STIHL gasoline-powered equipment runs on a 50:1 mixture of gasoline and 2-cycle engine oil.
All Weed Eater brand two-cycle gas trimmers use a 40:1 ratio of gas to oil. That`s equal to 3.2 ounces of oil to 1 gallon of regular gas.
Use a 32:1 gasoline to oil ratio. One gallon of gasoline combined with 4 oz of two-cycle engine oil.
Most string trimmers have a cutting diameter of 10-15 inches, meaning that the optimal line length will be about half of that, minus the central part of the trimmer head. Most guards are equipped with a discreetly placed blade that cuts off the excess and prevents the line from getting too long.
Example 2 – The commercial string trimmer burns ¼ gallon of gas/oil mixture per hour of operation.
With gas string trimmers, it`s important to check and add oil if the levels are low. Make sure to only add oil to the fill line. Overfilling the tank can damage the internal parts. You should also change the oil regularly.
For a 40:1 mixture, use 3.2 fluid ounces of oil per gallon of gas. For a 32:1 mixture, use 4 fluid ounces of oil per gallon of gas.
If you`re using a different brand of 2-Stroke oil, you`ll need to mix at 25:1 (40mls oil per 1 litre fuel). Petrol has limited shelf life (as low as 30 days), so always mix with fresh regular unleaded purchased from a reputable large volume fuel supplier.
A 100ml bottle is suitable for mixing with 5 litres of fuel to achieve a 50:1 fuel-oil ratio.
Light: 0.065- to 0.080-inch line is best for trimming grass around the house and whacking down common lawn weeds from around driveways, walkways and fences. Medium: 0.080 to 0.110-inch line is best for homes with larger lawns, or gardens overgrown with weeds that have tough, heavy stems. Heavy: 0.110-inch and above.
The recommended ratio of fuel mix is 1 part oil to 50 parts petrol. For example, if you are using 5L of petrol, you will need 0.1L (100ml) of 2 Stroke Oil. To mix the fuel, pour the 2 Stroke engine oil into a mixing can that is approved for use with fuel, then add the petrol.
What is the ratio for 2-stroke fuel mix? Most modern petrol garden machinery requires a 50:1 ratio mix of petrol to oil. This means for every 1 litre of petrol you must mix 20ml of oil.
You will need to mix fresh unleaded petrol (not older than 4-6 weeks) with 2-stroke engine oil, at a 40:1 ratio.
