There are many kinds of hibiscus flowers, some can grow up to 4-5 meters high, regular pruning is conducive to flowering.

Selection of growth time and planting time of hibiscus flower

Hibiscus is a brightly colored perennial that can grow up to 4.6 meters tall where there is no frost. Large gorgeous flowers can be in a variety of colors or bicolor. Hibiscus shrubs are deciduous plants with dark green leaves.

Growth period

The growth rate of hibiscus depends on many factors. These factors include the location of planting, the mode of transmission and the weather conditions that usually occur. Some varieties of hibiscus take up to 18 months to blossom. If hibiscus is purchased as a mature plant, it usually blossoms in the same year it is planted.

Preference for soil and light

Hibiscus plants perform best in well-drained soil. These flowers need to be often wet, but not drenched. If the soil is not fertile, compost can be mixed with the soil used for landfills. Hibiscus needs to be planted in sunny areas. They also perform well in pots, which need to be placed in the sun for hours a day.

When and how to plant

Hibiscus can be planted at any time in spring, summer or autumn. These plants need to be separated by about 0.9 to 1.8 meters. The hole dug only needs to be as deep as the root ball. The width of the hole is about 2 or 3 times the width of the root ball.

Variety

There are many varieties of hibiscus. A common garden variety is usually a solid color. However, tropical hibiscus varieties have flowers of more than one color. All kinds of hibiscus are perennials. Some species grow into large shrubs or medium-sized trees after a few years.

There is more than one kind of hibiscus, there are so many

Hibiscus flower (hibiscus spp.) It is a big and gorgeous flower, which is the protagonist of the midsummer garden. While many other plants struggle with high humidity and temperature, these tough plants have shown a prosperous scene. And surprisingly, some hibiscus plants grow well in mild temperatures in the southwest.

About the southwest

The southwestern United States, usually defined as a state from New York to Maine, has moderate summers, cold winters and a lot of snow. The area belongs to areas 3b to 6 of the USDA flora, and the average winter temperature is between-17.8 ℃ and minus-37.2 ℃. Gardeners in most parts of the southwest can choose from different types of hibiscus.

Red hibiscus

The red or crimson hibiscus (petunia) is cold-resistant and is suitable for growing in gardens in milder areas of the southwest. This is a perennial native plant with bright red flowers ranging from 15.2 cm to 20.3 cm in star shape. The stout leaves were deeply cut. Red hibiscus can be planted in sunny sunshine, wet or even swampy soil.

Rose mallow

Rose mallow, commonly known as hard hibiscus, is another kind of perennial hibiscus growing in the eastern United States. In spring, the dormancy rate of rose mallow is very slow, so mark its position carefully so that you don't accidentally disturb its roots. Once the rose mallow begins to grow, it will soon turn into a shrub 0.6 to 0.9 meters high, covering 30.5 centimeters of flowers. Many varieties are available, mainly red, white and pink. The hardy hibiscus grows well in the sun and wet soil.

Hibiscus

Sharon shrub, also known as shrub, is a deciduous shrub 2.4 to 3 meters high, with a vascular-like growth habit. This shrub blossoms on new branches, so it can be strictly pruned in the spring to control its size and shape. Like hardy hibiscus, Sharon shrubs grow slowly in spring. Once it begins to blossom in midsummer, it lasts until frost. These flowers are blue, white or pink, usually with a darker color in the middle. These shrubs can tolerate all kinds of soil and grow well in the barren soil of the city. Sharon shrubs bloom well in the sun or in shady places and are hardy in 5 to 9 areas.

Hibiscus flowers can grow up to 4-5 meters high and need to be pruned once a day.

From July to September, hibiscus shrubs (hibiscus flowers) bloom brightly. White, pink and red flowers look beautiful in landscaping, but hibiscus should not be planted arbitrarily. In the early stages, the shrub may look small and compact, but as it matures, hibiscus spreads and grows. Gardeners must prepare for the final height and spread of hibiscus to avoid a difficult transplant process.

Cultivate

Properly cultivated hibiscus plants will reach their maximum potential. Unhealthy plants will show stunted, short growth, and, if they exist, will not bring any benefit to the garden environment. Give hibiscus plenty of sunlight and light, well-drained soil. Heavy clay hinders the growth of roots, and hibiscus may not grow under such conditions. Repair the wet, high-density soil with sand so that it can drain well.

Height and width

Hibiscus shrubs can grow up to 4.5 meters tall, although they are usually no more than 2.1 meters tall in planting environments. In the widest part, hibiscus shrubs can stretch to 1.5 meters. These largest sizes should be taken into account when choosing the planting site of hibiscus. Pay special attention to the shaded areas of the lawn because plants need plenty of sunlight to grow and blossom normally.

Root propagation

The roots of hibiscus are not very widespread. A 3-gallon container, about 25 centimeters wide, is large enough to hold a hibiscus bush. Potted hibiscus can grow in a 25-centimeter jar, but there is no limit, and the roots will be scattered for several meters in all directions.

Pruning

Gardeners may follow their own aesthetics when pruning hibiscus bushes. You can leave the hibiscus in its own area and let it grow and spread at will, or you can prune it to maintain a neat and clean shape. Otherwise, you should trim the hibiscus regularly to remove all sick, dead and damaged branches. Trim the hibiscus at least once a year to remove all unhealthy parts.
