Your guide to watering newly planted trees and hedges

Posted on: August 4th 2025 • Posted in: Uncategorized

To give your new trees and hedges the very best chance to establish and thrive, correct watering is essential, especially during the first three years after planting.

Planting trees and hedges is an investment in the long-term sustainability of your garden or landscape. However, many often make the mistake of thinking that once the plants are in the ground, nature will take care of the rest. In reality, watering newly planted trees and hedges is one of the most crucial steps in ensuring their survival and growth.

When a tree or hedge is first planted, it is in a vulnerable state as it’s roots are still compact and limited to the soil around the planting hole. Unlike established plants that have extensive root systems reaching deep into the ground for moisture, new plantings rely entirely on the water you provide. Without consistent hydration young plants can quickly become stressed – leaves wilt, growth slows down, and in the worst case, they won’t survive their first summer. Below we have complied a simple guide to help establish both the plants and yourself into a watering routine.

Why does watering matter so much?

Root establishment: Water helps young roots expand into the surrounding soil, anchoring the plant and accessing nutrients.
Stress reduction: Adequate hydration minimizes transplant shock, allowing plants to adapt to their new environment.
Nutrient uptake: Water dissolves soil nutrients, making them available to roots.
Long-term resilience: Trees and hedges that receive proper watering in their first years are stronger and more drought-tolerant later.

How Often Should You Water?

The frequency depends on factors such as soil type, weather, and plant size, but general guidelines are:

Immediately after planting: Water thoroughly to eliminate air pockets and settle the soil around roots.
First few weeks: Water every 2–3 days, especially in dry or hot weather.
Following months: Gradually reduce to once or twice a week, providing deep soaks rather than light sprinkling.
First one to two years: Continue regular watering until roots are well established.

Tips for best results

Check before you water
Feel the soil 5–10cm down. If it feels dry, water. If still moist, wait a day or two.
Morning watering: Watering early in the day reduces evaporation and allows plants to absorb moisture before the heat sets in.
Water deeply, not lightly: A thorough soak is better than frequent splashes. This encourages roots to grow down, not stay at the surface. Focus water at the base of plants, not on leaves.
Avoid overwatering: Constantly soggy soil prevents roots from breathing and can rot young plants. Use a hose with a gentle spray, a watering can with a rose, or a drip irrigation system.
Mulching: Apply a 2-3 inch layer of woodchip, compost or bark around the base to help retain soil moisture to retain moisture and regulate soil temperature. Ensure you keep the mulch a few centimetres away from the stem to prevent it from rotting.
Give it a year or two: Continue watering into the second growing season, especially during dry periods.
