After the frost of last week, the return of the heat is an invitation to bloom, windows and balconies. For the urban deprived of chlorophyll, but also the rural people who were not all, far from it, the chance to have a garden, this is an important appointment which we have been preparing for weeks with a lot of questions: what species to choose? How to plant? In what type of pot? With any potting soil?

In spite of their image unfairly old-fashioned, geraniums (or pelargoniums, their true botanical name) remain the flowers the most popular. He sells every year more than 50 million plants in France, almost one per inhabitant! It must be said that the “king of the balconies” has something to appeal: a generous flowering from may to the first frosts, a variety of colours outstanding, and a culture easy to reach. Originating in South Africa, ivy geraniums, or zonal (recognizable at the spot in the shape of a horseshoe that adorns its leaves) are quite well to short periods of drought: one can “forget” to water them for a day or two without incurring life-threatening. And if they are allergic to the cold, they keep for even a year on the condition of the winters frost-free.

geranium zonal Moonlight Tumbao benefits since this year, with two other varieties, the red Label. Selecta

today, some fifty varieties in different colours (white, pink, red, orange, purple) enjoy a famous Red Label. Awarded by a jury composed of experts and enthusiasts under the auspices of Excellence plant, this certificate guarantees a “free-flowering, and continues” as well as “rapid growth and harmonious” of these geraniums high end of the range. Three new products have been registered this year: ’M Pink Splash’ with its sumptuous petals bicolored, BIG 5 Neon Pink’ with its cascade of flowers fuchsia and ‘Tumbao’ to the corolla bright red.

native to Argentina, petunias are also great used in the balconies.

If you are not sure to be diligent in terms of watering, you can compose your window boxes with resistant species (up to a certain point all the same…) to water stress: phlomis, coréopsis, santoline, verbenas, lantanas, not to mention the dipladénia, the gazania and portulaca ornamental. Consider also the exposure of your windows, and balconies; some plants need sun (geraniums, petunias…) when others are afraid or are allergic to them (begonia hemangioma, fuchsias, etc.). Finally, you can embellish your compositions with the “green”, in other words, the plants foliage is decorative as ivy, hostas or grasses.

“Fertilizer delay”

From a practical point of view, take a container deep enough (15 cm minimum) with solid carriers to be able to hang without the risk of falling to your balconies or window sills. Preferably, choose a potting soil planting “fertilizer delay” that will bring your plants the nutrients that are essential as their needs. Do not plant too tight if you want them to develop properly: a space of 20 cm between two plants of type geranium, is a good average. Water regularly, especially in summer where, in the case of high heat, the water input must be daily. Systems of automatic watering system with efficient and cheap exist if you are not sure to be available all the time. Also, remember to remove regularly the faded flowers to encourage your plant to produce new ones. Finally, if you live in a region that is frost-shattered, wait until all risk of frost has passed, to make your plantations. The ice Saints (may 11 to 13) are a good benchmark in most situations.
