The most well-known balcony plants are geranium and azalea. The first is a plant native to South Africa, the most common species of which is the scientifically named pelargonium: pelargoniums are those that everyone knows, while geraniums themselves are a differentiated botanical species. Its strength and adaptability to all climates during the good season make this flower the undisputed king of the balconies. Geranium among its most prized species is the one that has large double flowers and is suitable for growing in pots and therefore, can be displayed on balconies and terraces. Another example is the one with the characteristic variegated pink and white flowers that have a shape similar to that of the azalea flower. The latter, on the other hand, originates from China and Japan and was introduced in Europe in the early nineteenth century. It is one of the most well-known and widespread plants for its resistance and adaptability to cultivation in pots and boxes and has the advantage of blooming even for tens of years. Among the numerous varieties of azaleas, those with persistent leaves are best suited for growing in pots on balconies and allow for early flowering. The predominant color is lilac with flowers of various sizes and long, lanceolate leaves. Geranium and azalea belong to the category of perennial plants and have a permanent root system that bloom again every spring. During the winter they almost completely lose the leaves and the stems which become dry and therefore must be cut at the end of winter.
How to grow balcony geraniums
Geraniums can already be purchased in pots from gardening centers or in specialized shops. In the spring, when the risk of frost no longer exists, they are removed from the pots and transplanted into boxes or in the flower bed after preparing a soil that is not too rich in organic materials. It is advisable to water abundantly after transplanting but afterwards excesses must be avoided as the geranium resists well in dry soils. However, normal weeding and regular fertilization of the soil with specific fertilizers is necessary. It is necessary to always remove the withered flowers and dry leaves; to still have a beautiful and rigorous flowering after the summer holidays, before leaving you must provide a robust topping of the plants. If you want to preserve the geranium plants during the winter you have to remove them from the ground at the first sign of cold and pot them with the same soil, cutting the vegetation twelve or fifteen centimeters from the collar; it is advisable to keep them in a bright, not humid place, at a minimum temperature of eight or ten degrees, watering them very little during the whole winter period. Geraniums are real herbaceous plants with a prolonged flowering period, which adapt very well not only to balconies but also to wallpaper the ground or a garden. They are quite easy to grow; they thrive easily in moderately fertile soil, provided it is well drained as they are plants that cannot withstand stagnant humidity. It is preferable to place them in the shade, they can be left outdoors even in winter and in some cases reach a height of even eighty centimeters.
