When you apply lime, you’re not just raising the pH; you’re also making essential nutrients more available to your plants.
To get it right, consider the following:
Lime application timing: Apply lime in the fall or early spring when the soil is cooler, as this allows it to break down slowly and evenly.
Soil aeration methods: Before applying lime, loosen the soil to a depth of 8-10 inches using a tiller or shovel to guarantee the lime reaches the root zone.
Mix lime into the soil thoroughly to avoid creating pockets of high pH.
Apply the recommended amount of lime based on your soil test results to avoid over-liming.
Follow up with regular soil tests to monitor the pH level and adjust your lime application strategy as needed.
Use Wood Ash Strategically
When incorporating wood ash into your soil, strategically allocate it to areas where it can provide the most benefit, as this byproduct of wood combustion can be a valuable resource for improving soil health.
Wood ash has a high ash content, which can effectively raise the pH of acidic soils, making it an ideal amendment for acidic or neutral soils. You can use wood ash to neutralize soil acidity, especially in areas with high rainfall or where you’ve applied acidic fertilizers.
To reap the wood benefits, apply wood ash around the base of plants that thrive in alkaline conditions, such as roses, lilacs, or clematis.
Mix 1-2 cups of wood ash into the soil around the plant, taking care not to overdo it, as excessive ash can harm plants. Wood ash also provides micronutrients like potassium, calcium, and magnesium, which promote healthy plant growth.
