Outdoor flowers to decorate the garden
The choice of outdoor flowers, whether it is to beautify a balcony or a terrace, or to decorate a garden, is often presented as very complicated: not because the range of options among which to make your selection is limited, but rather because we have to deal, as they say, with the embarrassment of choice, there are so many species on which we can bet. It should also be noted that the flowers and plants must be cultivated taking into account, first of all, the exposure to the sun of the ground or the balcony: since, in fact, there are plants that can perfectly resist the sun's rays. and plants that, on the other hand, tolerate the first temperature rises with difficulty, it is advisable to know in depth the flower for which one has opted. Of course, we must never forget that setting up a garden or decorating a balcony are above all a pleasure, and should not turn into an obligation or a task to be respected reluctantly. Much better, therefore, to give free rein to creativity and imagination, combining different colors and blooms according to your tastes, giving life to lively and chromatically spectacular compositions.
The flowers to expose to the sun
In particular, for terraces and balconies exposed to sunlight, the recommended outdoor flowers are mini-surfinia (also called million bells), angelonia, diascia, lobularia maritima (also known as the annual alyss), Bidens, Argyranthemum, Lantana camara, Snapdragon, Brachycome iberidifolia, Euphorbia marginata, Convolvulus cneorum, Coreopsis, Convolvulus sabatius, Lavender, Lantana sellowiana, Lobelia, Laurentia axillaris, the stella de oro, the geranium, the gazania, the gaillardia, the zinnia, the verbena, the plumbago, the African daisy, the petunia, the mesembryanthemum delosperma cooperi, the sanvitalia, the nasturtium, the thymophylla tenuiloba, the pentas lanceolata, the nicotiana, ornamental sage, purslane and salvia splendens. It is important not to forget that, in order to bloom, seasonal plants need constant help, represented by a not excessive dose of manure, to be poured into planters, and by specific liquid fertilizer for flowering plants to be used in the warm months. As regards the leafy and accompanying plants that tolerate the sun well, we point out the thyme, the cineraria maritima, the sedum, the dichondra argentea, the acorus ogon, the santolina, the American potato, the creeping evonimo , muehlenbeckia, variegated carex, helichrysum petiolare and variegated ivy. For the grounds and the half-shaded balconies, however, the torenia, the fuchsia, the marigold, the surfinia, the variegated-leaf nasturtium, the coleus, the nemesia, the mountain daisy, the lobelia, the campanula are especially indicated. glass flowers, impatiens, heliotrope, chelone oblique, begonia, ageratum, calceolaria, agatea and bacopa. Among the leafy and accompanying plants, however, it is worth mentioning the tradescantia (also known as zebrina), the hosta, the asparagus, the cineraria maritima, the begonia rex, the small hebe , liriope variegata, resins, peperomia, oxalis regnelli, strobilanthes dyerianus, lysimachia nummullaria aurea, glechoma hederacea variegata, lamium and ophiopogon planiscapus.
It should be specified that the choice of flowers must be made after also taking into consideration the type of soil in which they will be destined to grow. In the event that pot cultivation is preferred, there is no problem, in the sense that the single soil can be made more acidic or basic according to needs, and possibly enriched with nutrients. On the other hand, the situation of cultivation in the open ground is different: in this case, in fact, it is not necessary to adapt the soil to the flowers, but the flowers to the soil. In short, you need to buy and plant only flowers that will be able to thrive in those conditions.
Outdoor flowers: Irrigation
Another aspect on which it is advisable to pay attention regards the administration of water: given that each plant manifests specific needs, we must never forget a general rule, which applies to any species: that is, that it is better, for flowers (but also for succulents, bonsai, etc.), have less water than more water than necessary. Excessive irrigation, in fact, prevents the soil from draining as it would be necessary, and therefore to drain the water; the risk is that water stagnations form which could give rise to unpleasant situations (for example, fungal infections caused by excessive humidity that risk damaging the roots of the flowers causing rot). The problem is all the more accentuated in flowers grown in plastic pots, while those located in terracotta pots can count on the high transpiration guaranteed by this material, which favors a rather consistent evaporation.
Finally, one last aspect to take into consideration concerns the possible attacks brought by insects and parasites: the action of red spider mites, mealybugs and aphids can be countered simply with the use of specific anti-parasitic products, which can be found in any garden. center. The whitish spots that these "enemies" should eventually leave, however, can be removed with a solution of linseed oil.
