It is late spring and our terrace or window sill that is in need of a remise en forme in order to finally be able to enjoy the beauty of the best seasonal flowers and especially being outdoors. But what are the moves to do?
CLEANING OF THE PLANTS
First, it is necessary an accurate cleaning of the plants by the leaves are damaged, the removal of branches and dried flowers and the filling of the pots with a little earth. Then, since we are in full vegetative growth, you must first take care of their nourishment or fertilization.
FERTILIZATION OF POT PLANTS
This is anoperation of vital importance , especially for the shrubs and flowers grown in pots, which have little soil in which to expand their roots in search of nutrients they need to live. In nature, this function takes place without any direct intervention, but the terrace is an artificial ecosystem that must be appropriately controlled and managed.
There are two types of fertilization, the mineral and the organic, I’ll tell you, I am inclined to organic not only because it employs fertilizers derived exclusively from natural substances, but above all because it improves the fertility of the soil.
A clarification. If it is operated properly during the winter season with a balanced intake of organic substances, the interventions of fertilization in spring and late autumn can be less challenging, marked on a monthly basis and above all to the need that is the arising of suffering immediately visible in the variation of the coloration of the leaves may appear yellowed, lighter or darker than usual or stained.
In this case, the council is to consult a gardener or nurseryman of trust with a sample of leaf or a single photo to identify the deficiency of nutrient and the remedy therefor. I recommend you follow the dosing instructions recommended in the package, to avoid excess product just as harmful
As I said, the fertilizers that you can find in commerce are divided into organic and mineral, to be used preferably in combination.
Given the wide variety of possible sources from which they origin (animal, vegetable or mixed), there are many. During the decomposition process are transformed into humus, a useful element for the physical structure of the soil and is essential to the life of micro-organisms such as bacteria, fungi, insects and earthworms that promote fertility.
WHAT ARE ORGANIC FERTILIZERS AND HOW TO USE
Manure pellets, is readily available at any garden center or consortium agrario in convenient bags from 5 to 25kg (25 kg cost about € 23), has an unpleasant smell for a few days, but its nutritional properties are exceptional.
And this product has a slow release that guarantees that is, contributions for long periods of time, and avoid burning the plants ‘ roots with excessive nutrient concentrations. To use in the fall and winter for all the plants to the exclusion of the plants acidophilic plants (azaleas, rhododendrons, camellias, gardenias, hydrangeas, geranium). Go scattered on the inside of the pot, but on the surface, and away from the trunks (the moisture can cause the occurrence of fungal diseases in the collar or rot at the base of the plant), covered with a light dusting of earth, and left to work. As an alternative, for those who have pets, I suggest the manure is composted, odourless and therefore not attractive to four-legged friends that will enjoy it.
Lupin ground, is a slow release fertilizer, you can buy it at any dealer or via the internet (25 kg cost about € 22). Unlike the previous you source 100% vegetable, which is particularly suitable to fertilize citrus and other acidophilic plants. It should be used at the beginning of spring, just before the vegetative growth of the plants.
Scattered on the surface along the edges of the pot, if he waits for the decomposition, and only at this point we proceed with a slight landfill to avoid that, in the processing step goes in direct contact with the roots, damaging them.
The Humus of the earthworm, extraordinary natural fertilizer, precious and so expensive, 10 kg and cost about € 25. Although there are no particular restrictions on the period of use, it is recommended in late spring and in late summer when the soil is tired and in need of the most support. Easy to use because you just spread a thin layer on the ground, after having shaken the surface.
What are they, what are they and how to use
As an alternative to organic fertilizers is always possible to use the fertilizers, mineral-based: they contain a mixture of macro (nitrogen, phosphorus, potassium) and microelements (iron, calcium, magnesium, copper, zinc, etc.) essential to the nutrition of the soil and of the plants.
One of the great benefits of the fertilizer, mineral-based is without a doubt the easy availability. Every shop of flowers and plants has its own shelf with a wide variety of brands from which to find the right product for their needs. But how to make an informed choice without jeopardizing the health of their plants?
Before venturing into the purchase is for you to keep in mind one simple distinction: the one between fertilizers simple, that contain only one of the substances mentioned for specific nutritional deficiencies, such as in the case of chlorosis (lack of iron) for an action rinverdente, and complex fertilizers intended as a mixture of several elements for a proper supply of nutrients throughout the growth phase and development of the plant.
The products are liquid solutions (50ml cost between 8 € and 10€), water-soluble (a lot from 25kg varies between 40e 50 euro) and granular: the first two have an almost immediate effect and ideal for the season of maximum vegetative development, those granules have a sustained release in time and for that reason they are to be used preferably in the autumn or in late winter-spring.
But be careful not to use the mineral fertilizer in the moments of great heat and drought. The plant may be affected with a request for additional water to dissolve the nutrients in excess present in the soil. Never leave the ground of your vessel as soon as the fertilized dry!
If you choose granulated fertilizer for example, remember that the soil is always moist to avoid burn damage. A solution to risk is to use fertilizers with controlled release type Osmocote, market leading product for broad distribution throughout the national territory (osmocote fertilizer, universal, 750 grams, costs about € 8, while osmocote for citrus 1 kg costs about € 13).
In trade, however, there are now valuable products of leading specialized firms and also here, if you really do not know to find the fish, that is the old rule of always before buying: ask the advice of their seller or gardener of the trust.
