It sounds logical that adding sand would make the soil more porous but look again at the soil texture triangle.

Now those added stones and the destroyed soil structure significantly degrade the value of the land for other crops. As an Amazon Associate, we earn from qualifying purchases. The most common reasons for lavenders turning yellow are; excessive nitrogen in the soil, too much fertilizer, over watering, poor soil drainage or high humidity. So, should you add sand to soil for lavender plants? But what does this mean? Poor, sandy soil with low fertility and great drainage is ideal, so do not add anything to improve it unless you are on close to pure sand, in which case a sprinkle of compost will help them establish.

The bees that frequent my garden love my two lavender plants, which grow and flower with abandon.

For oxygen to enter the soil and carbon dioxide to leave, the large pores (macropores) through which gas exchange occures need to be continuous from the soil surface to a depth at least equal to the root depth of the plant. Plants need room to gather the sunlight, water, and nutrients they need to grow strong and healthy.

Some root pathogens actually swim toward roots surrounded by a high carbon dioxide/ low oxygen content. Introduction: An ideal soil is considered to consist of 45% mineral (sand, silt, and clay), 5% organic matter, and 50% pore space.
