The flower is botanically defined as the complex of organs deriving from the transformations of leaves that allow the higher plants to reproduce.
The fundamental purpose of flowering in natural conditions is precisely the multiplication of the plant, which occurs through the fertilization of the specific organs, which will later turn into fruits and seeds capable of spreading the species.
This function occurs in nature with a precise biological cycle, determined by a sum of favorable conditions which are: temperatures, great illumination, humidity and nutrition.
The size, structure and color of the flowers varies greatly even in the higher plant species, depending on the type of fertilization they require.
The major floral specialization is given by entomophilous fertilization plants (ie promoted by insects); in order to attract the pollinators, nature has endowed the flowers with showy colors of considerable size and nectars with fragrant fragrances.
Other plants, on the other hand, which require anemophilous fertilization (due to the wind) also have flowers, but they are much less showy and adapted to perform this function, for example corn which has long stigmas designed to collect pollen from the wind.
Flowering for ornamental purposes is one of the main reasons for cultivating many types of plants that can be distinguished on the basis of longevity in annuals or biennials, perennial shrubs or trees.
Another distinctive parameter is also the flowering period: spring for the majority of plants in our climates, but also summer, autumn, in rare winter cases.
The flowering aptitude is also very important, thus distinguishing species with a single annual flowering from other re-flowering ones, or capable of reproducing flowers continuously. This is the typical case of roses, where in the genus rosae we can distinguish re-flowering types or not
The simple answer is yes! but some precautions must be taken.
It must be said that in the flowering period the plants manifest a nutritional peak, determined by the fact that a lot of energy is required for the formation of the flowers, we also reiterate that among the first natural rules there is that of the maintenance of the species.
Therefore the plants transfer all the elaborates in favor of the flower and the fruits, therefore the first general consideration to make is just that of the alimentary condition of the flowering plant, that is to say the fertilization.
In the wide range of floral plants there are special techniques that allow to improve the quantity and duration of flowers that cannot be equally easily generalized.
Their good application and the result depends on the good knowledge of the type of plant that is the object of our attention, namely the species and the environmental aptitude (see for example roses) where it is necessary to intervene with specific knowledge.
Good indications for this purpose can therefore be portrayed both from the point of sale and from the varietal label that many producers apply to plants and where they specify the botanical name (and in the best cases the subgenres) with the main characteristics of the species and the ideal acclimatization.
As anticipated this is the basic technique to prepare the plant to form the buds, keep the flowers and intensify the color of all flowering plants. It is well known, in fact, that an imbalance, in excess or defect, at this stage totally frustrates flowering.
The typical example is the nitrogen: the excess leads to vegetative growth with scarcity of buds, while the lack of nitrogen, leads to stunted plants and early flower fall.
The title that best fits this stage is conventionally balanced in macronutrients and should include the main micronutrients in a balanced dose.
There are also numerous exceptions in this area where it is necessary to intervene with specific fertilizers such as flower Acidophiles (Azaleas, Rhododendrons, Camellias, Hydrangeas) which for their development purposes must contain an acid component in the fertilizer or the Succulent Plants which must contain modified macro-element rations, to then descend into the specific ambit of the flower type (see products for Geraniums, Petunias, Cyclamens, Hydrangeas, Roses and Orchids) which, thanks to their balanced composition, take on average the titrations that nursery gardeners employ on these plants, thus avoiding imbalances from nutritional changes between nursery and hobbyist.
Also in this category are the useful formulas that favor flowering, indicated in the case of vegetative stress (temperatures or momentary weakening of the plants), their common characteristic is that of promptly replenishing the plant with pre-processed natural nutrients such as amino acids and vitamins. THE
Pruning and Blossoming
The interventions that consist in the elimination of withered or faded flowers, except for some exceptions (hydrangeas or roses for the production of berries), in addition to beautifying the plant aesthetically, are simple techniques for improving the potential for flowering again.
The explanation is given by various reasons:
· The withered flower on sterile plants is a receptacle of various diseases, which on these parts proliferate, extending the infection to the remaining parts of the plant.
· The formation of fruit forces the plant to work extra, which on floricultural plants leads to a rapid debilitation.
The execution technique changes from species to species, for example for geraniums, azaleas, rhododendrons, cyclamens, petunias, it is performed with simple manual detachment, while for roses and chrysanthemums the operation changes according to the period.
It is called an unbutton if it consists in the elimination of the side buds that remove substances from the main one is performed by tearing with the fingers.
It is called topping if, on the contrary, it eliminates the central bud to favor the development of smaller lateral buds, thus giving the plant a compact appearance.
It is called pruning if the flower is cut in the bud phase with a stem, as in the case of the florist rose for the production of cut flowers, or in post flowering with parts of branches on some shrubs such as forsythia and broom and Budleia alternifolia for the production of new flourishing buds in the following year.
Blooms: Various pathologies
Along with those deriving from the environment (non-pathological) there are various pathological causes that can damage buds or flowers precisely because both insects and fungi prefer the tender shoots, in particular if they are sugary, as are all the floral parts.
Specifying immediately that the useful treatments to solve the various problems, should not be performed in flowering on ornamental plants in order not to annoy the pollinators and in order not to damage the flowers present (which are generally much more sensitive than the remaining parts of the plant) various treatments should be done preferably in a preventive form, that is the appearance of the first buds of the buds, or in any case in post-flowering with a curative title. Adversity due to fungi:
Leaf mold and buds
Oidium or mal white
Adversity due to insects
Aphids or lice
Destroyers of leaves and flowers or awls
