How to Apply Fertilizer to Lawns
845.jpg
Lawns are living things. Like other plants in your garden they do best with some food to keep them healthy. Mowing removes nitrogen, which can result in a yellow-looking, lifeless lawn. You can get both organic and inorganic lawn fertilizers and these are usually applied in spring and autumn. You will also find "weed and feed" products, which will help to control lawn weed problems at the same time as feeding the grass. These are best applied in spring. Its important to apply lawn fertilizers evenly to avoid damaging, or even killing, areas of grass, or creating variations in growth patterns. This workshop shows you the basics using a mechanical spreader if you have a large area or doing it manually. For further tips see Workshops: How to do Autumn Maintenance of a Lawn and How to do Spring Maintenance of a Lawn.

you will need
Fertilizer; gloves, a bucket (if fertilizing manually); 2 small plant pots, one inside the other so that the holes are closed (if fertilizing manually); 1 m canes (for fertilizing large lawns manually); a spreader (can be hired from tool hire shops - essential for larger lawns, more accurate than manual application). Optional: dust mask; tape to measure (for larger areas); scales to measure (for larger areas if no measure included with fertilizer).

step1
If using a spreader, measure your lawn and work out the application rate of the fertilizer you have chosen. Measure out half this amount -it's easier to spread in two batches, in two different directions to ensure even coverage. Put the first half in the spreader, making sure that the spreading holes are closed. If doing it manually, divide up your lawn into square metres using the canes. Work out the application rate of the fertilizer you have chosen, measure out and put into a bucket. Measure into the plant pots the correct amount for 1 square metre. Mark with a felt tip pen where this level is on the inside pot.

step2
If you're using a spreader, apply the first half of fertilizer to your lawn working up and down in strips, as you do when mowing. Close off the supply hole as you turn at the end of each row. Each strip should join but not overlap the last. You may want to set out canes on the ground as a guide, or use a garden line - both can be moved as you proceed. If you're doing it manually, fill the double pots with the right amount of fertilizer for a square metre. Slide the two pots slightly so that the holes open a fraction. Shake evenly over the first square metre. Remove cross canes so that you can see your progress. Continue in the same way until you have covered the whole lawn.

step3
If you're using a spreader you'll need to fill the spreader with the second half of the fertilizer. Apply this working across the lawn at right angles to the first application strips. Each strip should join the last but not overlap. Close off the supply hole when you turn at the end of each row. Continue until you have finished the lawn.
