What is Malva?
Malva is a genus of approximately 30 species of plants known as Mallows found in the family Malvaceae . Some are perennials that are grown as ornamental plants. Other species are annuals or biennials and, moreover, invasive weeds, especially in America and Australia. Mallows were used as food and medicines by people in different cultures since 6000 BC. Other plants known as Mallows are found in other families of this family. The cultivar known as Braveheart Tree Mallow was a permanent month in July 2005. It grows at 3 to 5 feet (0.9 and 1.5 m) high and produces 2-inch (5 cm) lilac or pink flowers with dark veins. Other popular cultivars include Zebrinus and Marina, which have purple stripes, on pink or purple blue flowers, appropriate. These types of plants prefer full sun and well -drained soil. This species is a drought tolerant in the northeast and the Midwest. It also prefers a full sun.
On the other hand, neglect, also known as an ordinary maid, along with Little Mallow, or Malva Parviflora , are invasive weeds on several continents. Both of these species are also known as Cheeseweed because small fruit are in the shape of a cheese wheel. They can be distinguished by the size of plants and flowers and the appearance of the fruit.
Ordinary mallow is a prostrate, while a small mallow can grow up to 6.5 feet (2 m) high. Its flowers are larger and its fruit is smooth and not squeezed, such as the little shining. Both species occur in almost all states of the US, a lot of Canada all Australian states. They are generally annuals or biennials, but can live as perennials for a short time.
Cheeseweeds is very difficult to eradat as soon as they infested a field or landscape. They are one of the few weeds that are not killed by glyphosphate or even blazing. Seeds can remain in the soil asleep for up to 100 years. Seeds capable of producing plants were obtained from brick adObe 200 years in Mexico. In addition, plants rapidly grow a deep taproot, which is very difficult to remove from the soil.
It is recommended to pull out the plants when they are young, ideally with four leaves. If the plants increase, one should use a hoe or cultivator to interrupt the root below the soil surface. When the mowers are used, Cheeseweeds just grow. Broadleaf headbicide 2.4-D has a certain effect on young plants. A thick layer of mulch prevents seed germination.
These weeds have become more of an agricultural cultural problem with an increase in crop areas that are kept without cultivation. A large number of these plants can reduce the yields of crops. They can also have many pathogens and insects that affect crops. This can also be a problem in the gardens.
Cheeseweeds are an alternative host of rust that infects Hollyhocks, a closely related species. Mallows grow quite well with colonies of rust on their leaves. However, Hollyhock plants are very weakened when colonized by HOllyhock rust. For this reason, it is strongly recommended when a person grows Hollyhocks to remove any Kalofs in the area.
