Basil plants often struggle in summer heat, turning brown and wilting, but a quick 30-second weekly task can keep them thriving. Gardener Deanna Talerico, founder of Homestead and Chill, recommends pinching off flower buds to encourage larger, healthier leaves.
Why Basil Struggles in Summer
Basil is one of the easiest herbs to grow, usually thriving on a kitchen windowsill. However, hot weather puts strain on the plant, causing it to flower prematurely. Flowering signals the end of the plant's lifespan, making leaves woody and shriveled as energy is diverted from leaf production.
The Pinching Solution
Deanna Talerico explains: “To delay flowering and encourage more fresh leaves to grow, it’s best to pinch off basil flowers soon after they form – especially early in the growing season.” Pinching removes flower buds, redirecting energy to leaf growth, resulting in bushier, more fragrant leaves. This simple task also prevents the production of auxin, a hormone that triggers flowering.
How to Pinch Basil
Locate flower buds at the tips of stems – small green spikes above the top pair of leaves. Pinch them off just above those leaves using fingers or scissors. Check the plant weekly, as flower spikes grow quickly. If flowers have already opened, remove them immediately to halt energy diversion.
Regular pinching keeps basil healthy and productive all summer, providing a continuous harvest of fresh leaves for recipes.
