Vitex /chaste tree is a native of China, it blooms
from late spring until early fall with long, upright spikes of pink, lilac and
white flowers. Its pleasant fragrant flowers and foliage attract butterflies
and bees, and it makes an excellent honey plant. Wildlife
shuns the seeds, and it`s just as well because you`ll have to remove the flower
spikes before they go to seed to keep the plant flowering. Chaste Tree
Cultivation Chaste trees need full sun and very well-drained soil. It`s best
not to plant them in soil that is rich in organic matter because organically
rich soils hold too much moisture close to the roots. Chaste trees do very well
in xeric gardens where water is scarce. Once established, you`ll probably never
have to water a chaste tree. Inorganic mulch, such as pebbles or stones, allows
the soil to dry between rains. Avoid using organic mulches such as bark,
shredded wood or straw. Fertilize the plant every year or two with general-purpose
fertilizer. Chaste trees freeze and die back to ground level during severe
weather. This isn`t a cause for concern because they regrow quickly from the
roots. Nurseries sometimes prune the plant into a small tree by removing some
of the main stems and all of the lower branches; but when it regrows, it will
be a multi-stemmed shrub. You`ll need to prune annually to control the shape
and size and encourage branching. In addition, you should remove the flower
spikes when the blossoms fade. Allowing the seeds that follow the flowers to
mature reduces the number of flower spikes late in the season. Vitex Honey,Pure Vitex Honey,Low Price Vitex Honey Ningxia Natural Honey Product Technology And Development Co., Ltd. , https://www.nxhoney.com
Identification of the disease in the field mainly damages the leaves and produces white-powdered spots (spores, conidiophores, and mycelia) that cover the foliage. When the damage is severe, a layer of white powder forms on the leaves. At the late stage of disease, the diseased leaves gradually wither and fall off.
The cause of the disease is in cold regions where pathogens remain on the ground for winter with the closed capsular shell. In the second spring, ascospores and ascospores are produced by the closed capsule, which is infested by airflow. White-powdered spots were then generated on the victim part; the conidia of the pathogen were re-infected by airflow. Shady, warm, cool, and damp, it is beneficial to the disease, but in arid environment, poor plant growth, weak disease resistance, and sometimes the disease is more serious.
