Question

How often should I water newly planted shrubs and perennials?

Answer

Newly planted shrubs and perennials need consistent watering to help them establish strong roots, especially during their first growing season. In general, water them thoroughly every one or two days for the first few weeks, then reduce to once or twice a week as they settle in. 

Aim to water deeply at the base of the plant so the moisture reaches the root zone, this encourages stronger, deeper roots. Water early in the morning and avoid doing so during the middle of the day when the sun is strongest, as this can encourage rapid water loss through transpiration and thus the plant can scorch.

To conserve moisture and reduce how often you need to water, mulch well around the base of each plant using bark, compost, or well-rotted manure. Mulch acts like a blanket, keeping the soil cool and locking in moisture.

With hosepipe bans becoming more likely during dry spells, it’s wise to think ahead, install water butts to collect rainwater, direct downpipes into barrels, and even reuse grey water from the kitchen when safe to do so. These small steps can make a big difference in keeping your garden thriving sustainably.
