Is Lime a Good Fertilizer?

Lime is often overlooked by gardeners as a fertilizer option. Many stick to traditional types such as nitrogen and potassium. Lime offers several advantages if used to balance soil and it helps certain plants gain the nutrients that they need.

Calcium

Lime is actually calcium oxide. It provides a good source of calcium to the soil and plants. Nearly all plants need calcium to survive and eventually thrive.

Modifies the PH Level

Many fertilizers used today actually lower the PH level of the soil. If it falls too low then the plants will not get the essential nutrients they need. Lime helps balance this problem. It can be beneficial when used after nitrogen to keep the PH level up.

Changes Soil Properties

Lime can change the physical and biological properties of the soil. This can lead to greater microbial activity, better air and water flow through the soil and an acceleration of the soil's decaying capabilities.

Keeps Insects Away

Lime can reduce the amount of insects in the garden. It increases the effectiveness of some herbicides but also acts as a natural irritant to insects.

Planting

Roses, Rhododendrons and lettuce all grow well when lime is used as a fertilizer. Lime also is effective in controlling weeds such as quack grass and jimson weed.
