Fertilize and Mulch a Garden

When you're ready to fertilize, spread the recommended amount evenly over your garden with a rototiller or spade. Mix or till the fertilizer 4" to 6" into the soil. Soil type dictates how often the fertilizer needs to be applied. Sandy soils require more frequent applications of nitrogen and other nutrients than clay-type soils.

Helpful Tip

Instructions on bag will inform you of how many pounds per square feet need to be applied. For reference, 10 lbs per 1,000 sq. feet is a common application.

Safety Alert!

Any fertilizer spilled on roads or sidewalks should be cleaned up promptly. Improper use of fertilizers may contribute to pollution of lakes and groundwater, so use a broom to sweep up spills immediately.

After applying fertilizer, water the area immediately with a garden hose.

It is very important to water your soil prior to mulching. Dry soil and mulch combined can actually prevent water from soaking into the ground. Use a garden hose and allow the water to soak into the soil 6 to 8 inches.

Remove existing weeds from the area you plan on mulching with a trowel.

Typically, wood chips and bark mulch work well within gardens because they are uniform and take a long time to decompose.

Layer mulch 2" to 4" deep. It should be thick enough to block light and keep weeds from sprouting. Be careful to keep mulch away from the crown of plants, as it could potentially kill the plant.

Mulch breaks down steadily over time. Replenish when just a thin layer remains. By adding mulch, you are improving your soil and reducing the need to water and pull weeds.

Great work! When you keep up with fertilization and mulching, you keep your garden thriving. Watch and enjoy your garden as it continues to flourish!
