Lavenders appreciate full sun. Grow them in shade and they grow out towards the sunlight, and they like a well-drained soil. They don’t like wet feet. They don’t need a lot of fertiliser but some dolomitic lime in spring and autumn helps, and add some potassium to intensify the colour and strengthen the stems.
These plants develop a good root system, so they don’t need too much water. As lavender plants age, bushes can become woody. When pruning it’s important to retain the green foliage and don’t cut back into the old wood.
Lavenders can be propagated by seed but you run the risk of cross pollination and remember some are prone to becoming weedy. Check with your local council whether they’re weeds in your area before planting. Propagate by taking cuttings – either with a heel on soft wood or take older semi-hardwood cuttings. Just put them into the soil or into an open mix.
The flower spikes of lavender are used for floral arrangements and the pale purple buds are perfect for potpourri. The plant’s oils are used as an antiseptic and are now commonly used in aromatherapy. Lavender is a great plant for pots and tubs. You can also use them around the garden as a hedge or mass plant them as a feature. Lavenders are really versatile plants.
