Catalpa mosquitoes: general characteristics

Catalpa is a mosquito repellent plant from the regions of North America, Central America and East Asia. It belongs to the Bignoniaceae family and was discovered for the first time in 1777.

The foliage has a heart-shaped and trefoil and light green color; during the summer season it is possible to enjoy the beauty of the white inflorescences gathered in small panicles; to them, during the autumn season, are followed by fruits with a maximum size of about 50 centimeters and very similar to green beans with an elongated shape.

Catalpa mosquitoes: cultivation

The mosquito-repellent Catalpa is a rustic specimen that adapts to all climates. It prefers sunny or semi-shady positions, tolerates rigid temperatures but also short periods of drought. It does not need watering as it acquires the necessary mineral salts from the rains, and its deep root system is able to absorb the nutritional substances from the soil. With regard to young specimens, on the other hand, it is necessary to water regularly in such a way as to develop the roots, and between one irrigation and the other it is advisable to let the soil dry. During the planting of the mosquito-repellent Catalpa it is convenient to mix pumice stone and peat with the common soil and place the lapillus at the base of the hole, in such a way as to make the soil well drained. While it does not tolerate heavy soil with an acidic and poorly drained pH.

The mosquito-repellent Catalpa plant can be affected by some fungal parasites due to the climatic variation that occurs during the winter season and the frequent changes in humidity. In this regard, during the end of the winter season it is convenient to apply auburn on the plant. The parasite most feared by these specimens is Verticillium, which causes the foliage and branches to dry out. When the plant is still young or the attack is limited to specific areas, just eliminate the infected parts. One of the main properties that concern the Catalpa (besides the sedative, antiseptic and astringent ones) is that of being able to keep away some species of annoying insects, including mosquitoes. It is a genetically modified hybrid,
