The key to healthy transplants lies in their root development, which starts shortly after they’re planted. Water, in the right amount, is key to their early survival, growth and development. Too much water and the plants will drown, and too little will harm the roots.
A water or moisture meter is indispensable for assessing the soil moisture around their root zones. The meters use terms like low, medium and high or numbers from 1 to 4 to indicate the amount of water in the soil.
The ideal range for new transplants is in the medium range, or 2.5 to 3 on a numbered meter. It’s important to moderate the amount of water on the roots because flooding the plants replaces the oxygen in the soil with water, and plants that grow in soil need oxygen near their root zones. Without oxygen, plants can’t complete the photosynthesis cycle.
