Evergreens from the terrace
If we wish to have evergreen plants on our terrace, we must focus on "dwarf conifers" which, being small evergreens, create decorative spaces and require little time for their maintenance having a slow growth of just 5-10 cm. per year and do not reach the meter in 15 years if, of course, they are placed in suitable containers that will very slowly develop the roots due to the small size of the vase where we will place them.
On the terrace the "dwarf conifers" can be an accompaniment to other types of flowers by adding such a color with the white and the blue of the crocuses, the pink of the soap, the orange of the tulips and the yellow of the daffodils. Before buying a "dwarf conifer" it is good to evaluate the top of the plant which, if it is thin and sparse, can be a suffering plant because, to be healthy, the foliage must be thick, colored and without yellowing and the root must appear compact and heavy, wrapped by the roots and transplanted for at least a year and not removed from the nursery and recently possessed.
The "dwarf conifers" easier and more resistant, adaptable and decorative, especially for those who are at the beginning and have not yet developed the "green thumb", are the dwarf pine and the juniper that require only a few hours of direct sunlight per day. The Juniperus chinensis is the most widespread conifer and, in the Old Gold variety it is really ornamental with its yellow and bronze colors, also the Mugo Gnom Pine, with its spherical and compact shape, its dark and very thick needles, is not from less. There are more particular species such as the Cedar deadora or Cedro del'Himalaia, with pendulous branches and with light green needles or the Picea pungens glauca globosa, of the fir species, with large needles and a green-blue color with a very bark clear and, for those who want to amaze with a strangely shaped conifer, the orientation will be on the maximinoi pine from the collected but not closed shape, with a light and bright color that must be raised in pot only for some time because it is a tree real and therefore, over time, it should be placed in the ground.
Here's how to do proper cultivation.
The most suitable light
Conifers must be kept, both in winter and in spring and autumn, in full light, while in summer they need half shade and must be protected from direct sunlight. To protect our plants from very cold winter temperatures, it is good to adopt the double-pot technique by isolating the space between the two with insulating material such as polystyrene or with sheets of newspaper wrapped around themselves. In summer, on the other hand, because the plant does not dry out taking on a dull color and as soon as it is touched the vegetation tends to crumble, it must be repaired from the sun's rays especially if the conifer vase is very small, to prevent the earth from drying out quickly causing the "boiling" and "freeze-drying" because, once this degree is reached, no cure is needed anymore.
The recommended nutrition
The soil is of the acid type and, even if these plants can tackle any soil but prefer a loamy, loamy soil with a neutral pH, when it will be necessary to add new material, we will have to use a mix of peat and sand which it is found on the market already dosed in the right quantities. Once a year a product enriched with sulfur, iron and copper must be distributed, distributing it towards the outside of the vessel and not in contact with the trunk.
When to give water to the coniferous trees in pots
The soil should be kept fresh and the saucer should be removed in the middle and winter seasons to avoid water stagnation. Another tip is not to remove fallen needles but put them back in the jar, even those we find in the ground that contribute to making the soil more acidic, which is why no type of grass grows at the foot of conifers.
The time to repot our plants
It is not easy to understand the right time to carry out the repotting but, with a trick, we will solve the problem: we weigh the plant and, when the pot will seem light to us, it means that the plant will have "eaten" the whole earth and only the roots will have remained. We begin the operation of repotting by extracting the plant and, after letting the soil dry, we choose a vase of a size greater than the previous one and cut the overdeveloped roots leaving only the new ones and putting everything in the new pot. Let us remember to wait a couple of days before wetting to give the conifer the possibility of forming a callus.
It is not always necessary to carry out the pruning because it can bring the plant to fungal diseases and cause an unpleasant aesthetic result, especially in the falling conifers on which it is possible to use the return cuts technique in order not to alter the original geometry of the plant and allow it to have more branches robust.
The Japanese were the first to reproduce various types of very slow-growing plants but, in recent years, numerous varieties have been selected in the West to adapt them to solve any type of requirement with considerable success and to adapt them to the size of our homes which, over the years, have been significantly reduced.
