Knowing your soil type is key to irrigation.
You need to avoid saturating it. Too much water can suffocate roots and lead to pale, weak plants. Overwatering also flushes minerals into the water table, contributing to the pollution of drinkable water and increasing your fertilization costs.
Sandy soil drains better than clay soil. So you need to irrigate more often in sandy soil to prevent drought.
Clay soil holds way more water. You need to spread out watering. Let the soil dry a bit before adding more water. Otherwise, roots will choke and won’t be able to pump enough water to the plant. This will lead to growth stopping, mineral deficiencies, and fungal disease spread.
How long should you irrigate each time
Let's assume it’s a sunny day and we need 45 min of irrigation. To know the duration of each irrigation, we divide 45 min by the number of irrigations.
Again, you don’t need to remember all that. You’ll get a calculator in tip #6 that computes the various inputs into a daily irrigation plan !
