About soil condition, Althea prefers well-drained soil, but can also tolerate average to poor soils. Its deep taproot can also help to aerate heavy soils. Althaea is not drought tolerant, however, and requires regular watering during dry periods.
Like the other flowers, Althea need sunlight to grow properly. It is best to plant them in an area of your yard that gets at least 6 hours of sun each day. If you live in a climate with very hot summers, you may need to provide some afternoon shade for your Althea.
The temperature condition that is ideal for the growth of althea flowers is warm and humid. Althea flowers need a lot of moisture to grow and thrive, so they do best in environments where the temperature is consistently warm and there is high humidity. If the temperature drops too low, the flowers will not be able to grow properly and may even die.
Ideal humidity condition for this plant is around 50%. They cannot tolerate extremes of hot or cold and need stable temperature. If the humidity gets too high, it can cause fungal problems. If the humidity gets too low, it can cause the leaves to dry out and drop off.
For the fertilizer, this type of plant prefers something that is low in nitrogen. The best way to find out is by reading the back of the fertilizer bag. If it is high in nitrogen, it will say something like "for lawns" on the front of the bag. For the root, this plant prefers to have its roots in moist, but not soggy soil.
Pruning is an important part of keeping your althea plant healthy and ensuring that it blooms each year. You should prune your althea plant in late winter or early spring, before new growth begins. Cut back the plant by about one-third to one-half its height to encourage new growth and to keep the plant from getting too leggy.
Propagation is by seed, cuttings, or divisions. Sow seed in a cold frame as soon as it is ripe. If sown in early spring, it may bloom the same year. Take softwood or semi-ripe cuttings in late spring or early summer. Althaea can also be increased by divisions taken in spring.
Usually, the plant growth rate is determined by the species. The average growth rate for althea plants is about six inches per year. However, this can vary greatly depending on the plant's environment, nutrition, and other factors. Many althea flowers grow much faster than this, while others may grow more slowly.
Common problems for this kind of plant are powdery mildew, root rot, and rust. These problems are typically caused by too much moisture or too little light. To prevent these problems, water your althea flower regularly and make sure it gets plenty of sunlight.
