Planting and Care
Planting rosemary and lavender together in the garden involves careful consideration of their individual needs and preferences. Select a well-drained location with full sunlight, as both herbs thrive in these conditions.
Ensure the soil is slightly alkaline and amend it with well-rotted compost to enhance drainage and fertility. Leave at least 1 to 3 feet of space between each plant to allow for optimal air circulation, reducing the risk of disease and promoting healthy growth.
Before planting, water the herbs thoroughly and prepare the soil by loosening it with a garden fork. Dig holes slightly larger than the root balls of the rosemary and lavender plants. Water the newly planted rosemary and lavender generously to settle the soil around the roots.
To care for your rosemary and lavender, prune plants in early spring to shape and remove winter damage. Don't shear lavender too severely. Water plants 1-2 inches per week during summer and reduce in other seasons. Water at soil level.
Here are some additional care tips:
- Use organic mulch like wood chips or gravel to help retain moisture and reduce weeds.
- Stake tall varieties if needed to prevent flopping.
- Remove dead flowers regularly to encourage more blooms.
- Fertilize with organic balanced fertilizer once in early spring and again mid-summer if needed.
- Protect plants from hard freezes and winter wind.
