The easiest way to do this is to monitor your grass as it grows. Temperatures of up to 26°C will promote the growth of your lawn, on the contrary, if temperatures rise above 30°C, your lawn will hardly grow at all. If the grass is cut too short, it will burn and the soil will dry out. Any amount of watering will not save your lawn at this point. Therefore, it is a good idea to leave an extra few centimetres of length on your grass so that it stands at about five centimetres tall. Leaving a thin layer of grass cuttings from your previous mowing can help protect your lawn from too much sunshine. The best time to mow when you plan to do this is in the evening. Then you can simply leave the grass cuttings on your lawn. This keeps the moisture in and acts as a shield against the hot sun. To ensure that the grass cuttings are sufficiently aerated, you can mix in fibrous wood chippings.
If you want to water your lawn, it is better to water in the early morning rather than in the evening. The optimum watering time is between four and eight o'clock in the morning—this is when lawn irrigation has the most impact without the risk of provoking a fungal infestation. If this is a bit early for you, why not let the Gardena Water Computer MultiControl system help you out by watering your garden automatically for you. Your lawn is sufficiently watered when the top three to four centimetres of soil are soaked with water. An easier way to ensure this is to measure the quantity of water used. 10 to 15 litres of water per sq. m should be about right. However, do not underestimate the risks of overwatering your lawn. Overwatering can lead to mould formation, especially when your lawn is matted and not adequately scarified!
Watering done the right way!
Does a garden need to be watered a little every day? Well actually, no. If you thoroughly water your garden every two to three days either with a Gardena Classic Hose, or with the Gardena Pop-up Oscillating Sprinkler, then it should get sufficient moisture. The best solution is to place the hose directly on the plants and water until the earth is sufficiently damp. If you regularly loosen the soil around your plants, watering becomes more effective. When deciding when the best time for watering is, it is best to avoid the midday hours in which the sun is at its brightest. The best time for watering is in the morning when the soil is not yet too warm and less precious water will evaporate during watering. Be careful not to get water directly on flowers and leaves when watering. Water droplets on leaves act like a magnifying glass and intensify the effect of the sun's rays, often resulting in burnt leaves. Take care with roses too: On roses, wet leaves can lead to mildew and black spot.
Using mulch as a heat shield
That which protects your plant from the cold in the winter has the exact opposite effect in the summer: Mulching protects your plants against intense heat. As we illustrated above, simply spread a layer of three to five centimetres of shredded matter such as straw or bark over the entire garden area or around individual plants. Mulch also protects bed soil from powerful sunlight, preventing it from quickly drying out. However, take care to not spread grass cuttings that contain weeds, as this will prove unhealthy for your lawn.
Protecting young vegetable plants
You need to take extra care with plants that have recently been planted. Ensure that the soil is always sufficiently damp. It should never be completely dry. If necessary, you can place a water ring round each plant and fill this with water every day. A tried and tested method of watering tomato plants, for example, is to place a plant pot made of plastic or of clay with a diameter of 13 to 15 cm in the ground right next to the plant. Fill this with water twice a day so that when the weather is windy and hot, sensitive plants have some extra protection with a horticultural fleece.
