Established trees, shrubs and herbaceous perennials in beds and borders will only need watering in extreme drought. Just water the most stressed individual plants. Check for signs of stress – drooping leaves, especially in the early morning, often indicate drought Water slowly and thoroughly so that when you dig down, the soil is moist at a depth of 15cm (6in) borders with organic matter such as garden compost to help conserve moisture Avoid a routine such as “watering once a week”. Plants need different amounts depending on the weather, soil type, stage of establishment and size Containers and hanging baskets Check the daily from spring through to autumn, and water when it’s dry 2-3cm (1in) below the surface. Plants used for seasonal colour are often fast growing and have high water requirements. See our guide to watering containers If you are away in summer, consider setting up an automatic watering system for hanging baskets and containers During winter, rainfall is often enough to keep containers watered sufficiently. However, in dry, windy conditions, evergreen plants such as bamboo can desiccate, so it’s worth checking them, especially during prolonged dry spells. Seeds and seedlings  Use a watering can with a rose attachment to water the seed or border before sowing to ensure moisture is available for the roots as the seeds germinate. After sowing , water consistently to keep the surface moist. Young trees and shrubs Water newly planted trees and shrubs regularly during dry spells from spring to autumn in their first year, and large specimens for up to three summers. Water slowly, so it soaks in deeply around the Aim to moisten soil to a depth of 20-30cm (8-12in) – where the roots grow Plants below tree canopies, next to walls or under eaves in rain shadows may need watering even after rainfall Herbaceous perennials  In their first year, water around the base of the plant until the soil is evenly moist down to the depth of the roots – typically 15cm (6in). After the first year, established perennials usually do not need regular watering. Mulching with organic matter around plants will help prevent evaporation.  Lawns  Water newly seeded lawns regularly to prevent the top layer of soil from drying out. Use a watering can with a rose or a hose with a gentle spray. Water newly laid turf regularly, making sure the soil is damp underneath by lifting a corner to check. In warm, dry or windy conditions, newly seeded or turfed lawns may need to be watered daily. After three or four weeks, gradually move to less frequent but deeper watering, and still check the soil moisture levels regularly. Vegetables  Many vegetable and salad crops prefer consistent moisture, as they are quick growing. Leafy crops such as lettuce and spinach: keep the soil evenly moist Root crops such as carrots and beetroots: less frequent watering is needed Once plants are established and putting on growth, to keep watering to a minimum, water when drought will affect the part of the plant that is to be harvested See our guide to watering vegetables for more information Top Tip Keep your plants healthy as you water. Make sure you apply water to the base of plants, not on the foliage. This helps avoid fungal diseases.  Annual flowers If you’ve sown in spring, they will need watering in dry weather during summer and possibly into autumn. Self-seeded plants and autumn-sown annuals are less demanding. Use a trowel to check if the soil is damp at a depth of 15cm (6in) – if it’s dry, water Use the touch test to check how damp the soil or compost is below the surface. Top five water saving tips: 1. Choose the right plant for the right place 2. Improve soil with organic matter 3. Mulch borders annually 4 . Store rainwater from hard surfaces in water butts 5. Use mains water only as a last resort Timing makes a big difference to how effectively plants use water. Watering early in the morning is the best time. There will be less evaporation, and plants can use the water through the day Evening watering is acceptable, but damp leaves overnight can encourage pests and fungal diseases Avoid watering in the heat of the day – much of the water evaporates before reaching the roots Top Tip Deep, occasional watering encourages deep roots and drought-tolerant plants. Train your plants to be “drought athletes”. Watering cans are the most water-efficient method and give you the most control. Use hoses sparingly as they use more water. Sprinklers are one of the least efficient ways to water. Ideally, use a watering can and apply water directly to the soil or compost above the root zone. Did you know? Outside taps should have a double check valve to meet water regulations. The valve is designed to prevent any contamination flowing back into the mains supply. Yes, this is a very sustainable way of using resources. You can use washing up water (grey water) on ornamental plants, and collect rainwater in water butts to use directly on the garden.

There will be less evaporation, and plants can use the water through the day - Evening watering is acceptable, but damp leaves overnight can encourage pests and fungal diseases - Avoid watering in the heat of the day – much of the water evaporates before reaching the roots ### Top Tip Deep, occasional watering encourages deep roots and drought-tolerant plants. Train your plants to be “drought athletes”. ## Which method should I use? Watering cans are the most water-efficient method and give you the most control. Use hoses sparingly as they use more water. Sprinklers are one of the least efficient ways to water. ![Image](https://assets.rhs.org.uk/05836e9f-2692-012f-b4fe-e3f22d127fa9/0e8737b4-a152-486b-800b-6bf48670cf1d/watering-a-tree-in-a-container.jpg?fm=jpg&auto=format&w=800&fit=clip) Ideally, use a watering can and apply water directly to the soil or compost above the root zone. ### Did you know? Outside taps should have a double check valve to meet water regulations. The valve is designed to prevent any contamination flowing back into the mains supply. ## Can I use recycled water? Yes, this is a very sustainable way of using resources. You can use washing up water (grey water) on ornamental plants, and collect rainwater in water butts to use directly on the garden.

Established trees, shrubs and herbaceous perennials in beds and borders will only need watering in extreme drought. Just water the most stressed individual plants. - Check for signs of stress – drooping leaves, especially in the early morning, often indicate drought - Water slowly and thoroughly so that when you dig down, the soil is moist at a depth of 15cm (6in) - borders with [organic matter](https://www.rhs.org.uk/soil-composts-mulches/what-is-organic-matter) such as [garden compost](https://www.rhs.org.uk/soil-composts-mulches/composting) to help conserve moisture - Avoid a routine such as “watering once a week”. Plants need different amounts depending on the weather, soil type, stage of establishment and size ### **Containers and hanging baskets** Check the daily from spring through to autumn, and water when it’s dry 2-3cm (1in) below the surface. Plants used for seasonal colour are often fast growing and have high water requirements. - See our guide to [watering containers](https://www.rhs.org.uk/container-gardening/how-to-water-containers) - If you are away in summer, consider setting up an automatic watering system for [hanging baskets](https://www.rhs.org.uk/container-gardening/hanging-baskets) and containers During winter, rainfall is often enough to keep containers watered sufficiently. However, in dry, windy conditions, evergreen plants such as bamboo can desiccate, so it’s worth checking them, especially during prolonged dry spells. ### Seeds and seedlings Use a watering can with a rose attachment to water the seed or border before sowing to ensure moisture is available for the roots as the seeds germinate. After [sowing](https://www.rhs.org.uk/propagation/how-to-sow-seeds-outdoors), water consistently to keep the surface moist. ### Young trees and shrubs Water newly planted trees and shrubs regularly during dry spells from spring to autumn in their first year, and large specimens for up to three summers. - Water slowly, so it soaks in deeply around the - Aim to moisten soil to a depth of 20-30cm (8-12in) – where the roots grow - Plants below tree canopies, next to walls or under eaves in rain shadows may need watering even after rainfall ### Herbaceous perennials In their first year, water around the base of the plant until the soil is evenly moist down to the depth of the roots – typically 15cm (6in). After the first year, established perennials usually do not need regular watering. [Mulching with organic matter](https://www.rhs.org.uk/soil-composts-mulches/how-to-mulch-with-organic-matter) around plants will help prevent evaporation. ### Lawns Water newly [seeded lawns](https://www.rhs.org.uk/lawns/lawns-from-seed) regularly to prevent the top layer of soil from drying out. Use a watering can with a rose or a hose with a gentle spray. Water newly laid [turf](https://www.rhs.org.uk/lawns/lawns-from-turf) regularly, making sure the soil is damp underneath by lifting a corner to check. In warm, dry or windy conditions, newly seeded or turfed lawns may need to be watered daily. After three or four weeks, gradually move to less frequent but deeper watering, and still check the soil moisture levels regularly. ### Vegetables Many vegetable and salad crops prefer consistent moisture, as they are quick growing. - Leafy crops such as lettuce and spinach: keep the soil evenly moist - Root crops such as carrots and beetroots: less frequent watering is needed - Once plants are established and putting on growth, to keep watering to a minimum, water when drought will affect the part of the plant that is to be harvested - See our guide to [watering vegetables](https://www.rhs.org.uk/vegetables/watering) for more information ### Top Tip Keep your plants healthy as you water. Make sure you apply water to the base of plants, not on the foliage. This helps avoid fungal diseases. ### Annual flowers If you’ve sown in spring, they will need watering in dry weather during summer and possibly into autumn. Self-seeded plants and autumn-sown annuals are less demanding. - Use a trowel to check if the soil is damp at a depth of 15cm (6in) – if it’s dry, water ![Image](https://assets.rhs.org.uk/05836e9f-2692-012f-b4fe-e3f22d127fa9/bab20cdc-6a32-451b-b06c-77a07a00f7ae/checking-soil-moisture.jpg?fm=jpg&auto=format&w=800&fit=clip) Use the touch test to check how damp the soil or compost is below the surface. ### Top five water saving tips: **1\.** Choose the right plant for the right place **2\.** Improve soil with organic matter **3\.** Mulch borders annually **4**. Store rainwater from hard surfaces in water butts **5\.** Use mains water only as a last resort Timing makes a big difference to how effectively plants use water. - Watering early in the morning is the best time.
