Lavender, with its beautiful and highly fragrant blooms, is a popular choice for summer gardens. However, many gardeners make the mistake of overwatering these plants, which are naturally drought-tolerant and thrive in dry Mediterranean soil.

Stephanie Leblanc, a gardener and founder of Celebrated Herb, has warned that incorrect watering can attract pests and disease in the warmer weather, reports The Express.

She said: "Lavender plants like to be watered deeply and thoroughly, but it's important to avoid getting the foliage wet, as this can promote the growth of fungal diseases."

She added: "Instead, water the soil around the plant, aiming to keep the roots moist."

Deep watering encourages the roots to grow deep into the soil, but care must be taken not to leave the soil waterlogged. Stephanie further explained: "When watering, make sure the water runs through the soil and does not sit in water. Lavender plants prefer well-draining soil, so it's essential to avoid overwatering and ensure the soil has good drainage.", reports the Express.

In hot and dry weather, it's best to soak the soil deeply at around six to eight inches to ensure it's moist but not drowned. Signs of overwatering include yellowing leaves at the bottom of the plant, which can lead to root rot, mould or even fungal diseases.

To prevent overwatering, it's advised to check if the soil has somewhat dried out before watering your plants again. In cases where the soil is saturated, it's best to delay watering for a few days.

Yet, ensuring the soil retains moisture is crucial, as lavender can succumb to dryness, leading to brittle leaves and a lack of blooms.

For optimal care, it's suggested to verify the soil's dampness prior to each watering session and to water consistently every week, particularly in the mornings for the most favourable outcomes.

Stephanie added: "Lavender plants should be watered once or twice a week, depending on the weather conditions and the moisture content of the soil."

She also noted, "Additionally, for outdoor growing lavender, it's a good practice to water early in the morning to allow the foliage to dry before the heat of the day."

Morning waterings allow the ground ample time to gradually lose moisture throughout the day, hence averting the problem of waterlogged soil; meanwhile, the cooler temperatures of the morning reduce the rate of evaporation, ensuring that the plant roots have sufficient time to imbibe the water.

Adequate watering is key to mitigating heat stress during the summer months, encouraging more substantial nutrient uptake by the roots, resulting in a swift proliferation of vibrant flowers a sure fire way to maintain an exquisite garden.
