Lavender Plant Care in the Fall Starts with Pruning and Maintenance

As the weather cools down in the fall, it's essential to give your lavender plant some extra TLC to ensure it thrives through the winter months.

Pruning is a crucial step in lavender plant care in the fall, as it helps to control its size and shape, promoting healthy growth and preventing it from becoming leggy.

Lavender plants typically require pruning in the fall to remove any dead or damaged stems, which can be done by cutting them back to about one-third of their height.

To maintain your lavender plant's overall health, make sure to fertilize it with a balanced fertilizer in the fall, as this will give it the nutrients it needs to produce new growth.

A light layer of mulch around your lavender plants can help retain soil moisture and suppress weeds.

However, keep the mulch away from the plant's base to prevent moisture buildup and potential rot.

In areas with heavy snow or extremely cold temperatures, consider providing a light cover of evergreen boughs or a breathable garden fabric to protect the plants.

Lavender doesn't need additional fertilizer to grow and bloom, and too many nutrients in the soil can be a problem.

In fact, an excess of nitrogen can be especially detrimental.

However, giving your lavender an inch or two of compost mulch every year can provide a low and slow balanced diet of energy.

Apply the compost in late fall or early spring, covering the base of the plant without piling it up heavily around the main stems.
