Red Maple: Answer: Red Maple

Dear Flavio, thank you for having proposed your doubts to the "Questions and answers" section of our website. Red maple can be grown both in the garden and in pots. In both cases it is a plant that needs a humid place to live well and not excessive irrigation. If you want to put the red maple in a pot you will have to carefully choose the size of the pot: if you want a plant of at least 2 meters you will have to take a larger pot, while if you want a smaller maple and a smaller pot will suffice. . Regardless of the size of the maple, you must always keep these plants pruned: being in pots they cannot have a very developed aerial part in the face of a very limited space for the roots. Clearly, the smaller the pot, the more incisive the pruning must be. Finally, if you decide to put this plant in a pot, we advise you to equip yourself with universal soil or a loose and well-drained soil, an ideal growth substrate for this plant.

Red Maple: everything you need to know to grow it

L'red maple it is one of the most spectacular ornamental plants and can be grown in open fields and in pots.

Here's everything you need to know if you want to care for a scarlet maple plant.

  • Exposure and watering: the ideal place for scarlet maple is a semi-shaded area that allows the plant not to be exposed to direct sunlight for too many hours. The tree tolerates cold temperatures well but fears drafts. During the summer season it is advisable to nebulize the leaves daily to find the humidity conditions necessary for the correct development of the plant. For the same reason it also needs frequent watering. The land ofAcer rubrum, in fact, it must be well irrigated, well drained and never dry.
  • Ground: the ideal soil for scarlet maple is moist, slightly acidic or neutral and rich in nutrients. However, limestone soils should be avoided. For fertilization, to be carried out between March and June and from mid-August to mid-September, it is advisable to choose a slow-release fertilizer, paying close attention not to overdo the doses. If the plant is grown in pots, it is recommended to add humus during planting, to fertilize from early spring to autumn approximately every four weeks and to empty the saucer to avoid the risk of water stagnation. For transplanting into the ground, it is necessary to wait for the end of winter and the complete development of the root system. The first step is to dig a hole whose width and depth must correspond to double the portion of soil necessary to cover the roots. The land must be worked well and enriched with peat mixed with river sand. After planting, we proceed with the mulching of mature stallic or leaves to maintain the ideal humidity level and protect the roots.

  • Pruning: the perfect season is winter, but the scarlet maple can also be pruned in March before the buds swell to eliminate dry and broken branches. Attention: the tree should always be pruned away from the vegetative period and with suitable tools always disinfected before and after use. It should be noted that in some countries pruning is also carried out during the growing season to obtain the sugary substance from which the famous maple syrup is obtained. However, this is a very delicate operation that takes away energy from the plant and must only be carried out by experienced growers.
  • Multiplication of maple: occurs by stratification of seeds or by cutting in October. In the first case, the fruits of the maple, called samaras, open and the seeds are dispersed in the air thanks to the wind.
  • Illnesses: among the parasites that affect scarlet maple, especially in spring, there are aphids, spider mites and cochineals.

Son of Ares, god of war, and of Aphrodite, goddess of beauty, Fobos, together with his brother Deimos, god of terror, supported his father in every battle.
  2. Symbology: the tree is the symbol of the state of Rhode Island, in the New England region. In Canada, on the other hand, a stylized scarlet maple leaf with eleven points stands out in the center of the national flag and on military uniforms.

How is red maple grown in pots?

Grow red maple in pots or in the garden it is particularly simple since it is a plant that does not require great care or attention over time.

Of course, this does not mean that it should be ignored and allowed to grow undisturbed.

Especially when integrated in areas with a Mediterranean climate, in fact, it needs some extra care: the red maple, in fact, does not tolerate direct sun and therefore must be protected from too intrusive rays of the sun.

Having said that and choosing the right strain for you, it's time to choose the right container for the plant.

If you buy a very young and small plant, the advice is to start cultivation in a small pot which, however, will have to be changed over time as the plants grow.

As for the material, always choose a container in terracotta.

When it comes to land, what should be avoided is heavy soil, since it releases too much moisture at the root level at the same time, a soil that is too sandy would cause the water to drain too quickly.

Little care, but good: this is what red maple needs

The soil that will host your red maple should not be excessively salty, but an acidic and light substrate not excessively rich in organic matter. In this case, the soil that we advise you to choose is the one that proposes one common blend, perhaps lightened with sand and materials for acidophilic plants.

Regarding the fertilizeron the other hand, the administration of these products must be light and moderate and, above all, carried out at the end of winter. The ideal product is the slow release granular one and will be applied on the base of the stem.

On the front irrigation, on the other hand, correct watering is essential for the success of the cultivation of the piata. Potted red maples do not tolerate prolonged drought and should be watered whenever the soil is dry on the surface.

This procedure can be bypassed in winter, as long as the potted red maple is placed in the condition to receive rain water enough.

Finally, always remember that these plants, in general, also resist temperatures up to -15 ° C when it comes to potted red maple, however, these are less resistant and therefore they must be covered and kept away from wind, rain and frost during the colder seasons.
