Ten Golden Rules for Watering
To prevent your plants from hanging their heads in summer they need plenty of water. But how much or how often should they be watered? And is it better to water from above or below? GARDENA, one of the world's most reputable producers of intelligent garden-care products and watering solutions, recommends ten golden rules for watering your plants.
Rule no. 1: Keep the soil moist
Most plants depend on even moisture at all times. That said, if the soil dries out slightly before watering, this can help to promote root growth in plants.
Comfort Watering Computer with Calendar Function – G1862
Rule no. 2: Water less frequently, but thoroughly
For flower beds, one to two watering sessions per week is usually sufficient. It is better to water occasionally but with plenty of water rather than a little water often. GARDENA water timers with calendar function offer the perfect solution to scheduling your watering times. Simply program in the days to water, time of day (up to three cycles per day) and the duration per cycle, and you’re free to sit back and relax!
Rule no. 3: Water late in the evening or early in the morning
When you water cool soil in the evening or early morning, less water evaporates than when watering hot soil during the day. Watering of an evening or early morning also allows plants to sufficiently absorb the water before the next day’s heat.
Rule no. 4: Keep leaves dry
Wet leaves can become diseased leaves. Kept wet overnight, leaf-mould may result. Leaves that are wet in the day can develop slight burn marks from the sun.
Water Smart Flow Meter – G8188
Rule no. 5: Give the right water quantity
Requirement-suited watering means that the water must sufficiently reach the roots. Too little water will only cover the upper soil centimetres or may not even reach them at all (e.g. when there is mulch covering the soil). To ensure you give the right water quantity, invest in the GARDENA Water Smart Flow Meter which precisely measures the water quantity that has flowed with four options for measuring dispensed water quantities: the current flow rate, e.g. while operating a sprinkler; per watering session when watering e.g. flower beds; per day; or for the entire garden season. The desired function can be easily selected with a press of a button.
Rule no. 6: Give larger water quantities in parts
Water needs a moment to seep into the soil. To prevent precious water in the bed flowing away unused, it’s better to water repeatedly in sections rather than in one big hit.
Rule no. 7: Water with a set target but distribute evenly
Always watering at one root point will lead to one sided root growth, resulting in poor nutrient absorption from the soil. Therefore, always water around the plant and covering the entire irrigation area.
Soil Moisture Sensor – G1188
Rule no. 8: Irrigate in a way that saves water
Water as much as necessary with as little as possible. This can be simplified with a GARDENA Soil Moisture Sensor to determine the current soil moisture level, so you can give the right amount of water without wasting a drop.
Terraline™ Spading Fork – G3781
Rule no. 9: Avoid waterlogging
Waterlogging suppresses the oxygen to the roots and may result in the root cells drowning. Aerating the soil can help to prevent waterlogging. The easiest way to aerate the soil is with a garden fork, such as the new GARDENA Terraline™ Spading fork. Simply push the fork tines into the soil, rocking it back and forth to create sufficient aeration holes. Repeat the process at evenly spaced intervals around the garden bed or lawn.
Rule no. 10: Use quality, clay-rich soil
Plant soil rich in clay minerals has better expanding properties and can therefore hold water in the soil much better and in a more even way. In wet summers and in winter ensure adequate water drainage to prevent waterlogging.
