Watering seems simple enough, but it’s one of the most misunderstood aspects of garden care, especially in hotter months when too much or too little moisture can result in huge damage. Whether you’re nurturing leafy greens, colourful perennials, or potted patio plants, you’ll know each plant has its own needs.
According to gardening expert Harry Bodell at PriceYourJob.co.uk, “there is not one solid answer to this question, and your watering schedule may need to differ based on many different factors.” These include soil type, plant variety, local weather, and even how your garden is planted. Understanding these variables is key to finding the sweet spot between overwatering and underwatering – both of which can be harmful.
Overwatering can “drown the roots of your plants and lead to the soil becoming waterlogged”, while too little water “can cause unnecessary stress, leading plants to die out”.
Shallow watering only wets the surface and encourages weak root systems, whereas deep watering reaches the roots and promotes stronger growth. For this reason, it’s better to water less often but more thoroughly.
To find out when it’s time to water, Harry recommends: “Stick your finger into the soil about two inches deep.
“If it feels dry, this is a sign it is time to water your plants.”
As well as the soil check, watch out for wilting leaves or drooping stems, as they can also indicate a need for hydration.
Key summer factors to consider
Weather conditions: During heatwaves, some plants may need watering daily. But in more humid or rainy periods, you can pull back.
Soil type: Sandy soils drain quickly and dry out faster, while clay holds onto moisture and can easily become waterlogged. Loamy soil – the ideal middle ground – retains moisture without suffocating roots.
Plant type: Vegetables, young seedlings, and container plants typically need more water than mature shrubs or trees.
“Young plants and seedlings require more water because they are still growing,” said Harry, whereas established plants may only need a deep soak once or twice a week.
Containers vs. garden beds: Potted plants tend to dry out faster due to limited soil volume. In summer, they often need daily attention, particularly smaller pots in full sun.
