Question: Can I move my lilac to the ground?

On the terrace I have a beautiful potted lilac plant that has flowered. It has a few years and it seems to me that leaving it in the vase suffers. Could I transplant it into a garden 700 meters above sea level? Do you prefer a sheltered or sunny area? Thanks

Answer: cultivate the lilac

Dear Paola,
in fact, the lilac (syringa vulgaris) is a shrub that in nature also reaches 3-4 meters in height and loves to have a good amount of land to be able to develop at its best; surely your plant will benefit from being moved to the ground, because in the long run, the shrubs suffer, especially if they are not repotted periodically, and if you do not guarantee them a very large container.
You can easily move your shrub to the ground in the garden, because it is a rustic and vigorous plant, which also develops in the wild along our peninsula. The lilacs like to be grown in full sun, even more so if the garden in which the winter passes is in the hills, where winter temperatures can be very low. Before placing the shrub, work the soil well and enrich it with a little manure, or with a slow release granular fertilizer; they prefer very well drained and loose soils, possibly calcareous.
To have a good flowering every year it is good to remember that the lilacs prepare the flower buds already in summer and autumn; if therefore you can prune the shrub at the end of winter, you will go to remove most of the future flowers, obtaining a decidedly inconspicuous effect; if instead you wait to prune the end of the flowering, you will stimulate the plant to produce many new shoots, and therefore next year the flowering will make all your neighbors gnaw with envy.
Remember also that the potted plants have different needs than those in the open ground: your lilac, placed in the ground, will tend to need less watering, especially in the coming years, when it will have been able to develop a fairly extensive root system.
Once the lilac was widely used as a medicinal plant, while today it is cultivated only as an ornamental plant, or in some places it is forced to produce flowers to be cut; at one time an oil was prepared in which the bark of lilac was macerated, which was then used to massage the areas affected by rheumatic pains; still today the lilac is used in herbal medicine: the buds, extracted from syringa buds, are used for heart and coronary problems.
The species that is most used as a garden plant is syringa vulgaris, of which various hybrids have been prepared, with very particular flowers, for example there are varieties with a dark purple flower, with a white border.
