Soil pH is Essential for a Healthy Garden

Soil pH is an important part of gardening. It measures fertility of the soil and health of your plants. So what does pH mean and how does it effect our plants. pH stands for “potenz hydrogen” or potential hydrogen.  It is the ability of plants to attract hydrogen ions in the soil. It’s measured on a scale from 0-14, 7 is the most neutral. To put it simpler terms pH measures the acidity or alkalinity in the soil thus effecting the health of what you grow from landscape trees and shrubs to flowers, vegetables and even your lawn.

Many flowers, vegetables, and grasses prefer a ph level between 6.0-6.5 Plants like azalea, rhododendrons, and most evergreens, blueberries and potatoes are the exceptions, they prefer a ph level slightly higher than 7. Most plants can easily absorb available minerals in the soil like phosphorous, nitrogen, iron and potassium when the pH levels range from 6.0-6.5. When the soil pH is lower than 6.5 minerals like zinc phosphorous can be easily absorbed by the roots of the plant. Whatever your pH levels are too high or too low you can make minor adjustments by adding soil amendments. Adding organic matter or compost can help to bring the soil to a neutral base which is beneficial when growing most vegetables and flowering plants.

Finding out the pH is easy and can done at anytime during the growing season, but Spring and Fall are ideal especially if you are planting a new garden in a new area of your yard. There are easy at home testing kits available at your local garden center. Knowing the soil pH can help you make the appropriate fertilizer adjustments. If you need a more I depth analysis consult your local extension agency.
Some effects of soil imbalance in the garden include, underdeveloped growth and limited fruiting. This also effects the plants ability to fight of pests and diseases.

A few easy solutions you do now to lower soil ph is add water-soluble, Coffee grounds over time to help reduce pH, just like manure or compost.  Add Aluminum Sulfate to the soil to keep your blue hydrangeas blue. To correct high acidic soil pH simply add dolimite lime, calcium magnesium carbonate to the soil a few weeks before you plant.
