Considering the Soil

About soil conditions, magnolia bushes prefer acidic soil with a pH of 4.5 to 6.5. The soil should be well-drained with a lot of organic matter. The organic matter can be in the form of compost, manure, or peat.

Light requirement

Not too different with other plants, magnolia bushes need sun to grow and thrive. They should be planted in an area that gets six to eight hours of sunlight each day. While they can tolerate some shade, too much shade will cause the leaves to turn yellow and the plant to become less vigorous.

Ideal Temperature

The temperature condition that is ideal for a magnolia bush is anything above freezing. They can withstand very cold conditions and still look beautiful, making them a popular choice for winter gardens.

Humidity Level

Ideal humidity condition for this plant is between 40% to 60%. If the humidity is too low, the leaves will suffer and the plant may eventually die. If the humidity is too high, the plant may become susceptible to fungal diseases.

The Fertilizer

For the fertilizer, this plant prefers something with a low nitrogen content. This can be in the form of an organic compost or a slow-release fertilizer. For the roots, it is important to keep them moist but not waterlogged. This plant is not particularly tolerant of drought conditions.

Light requirement

Pruning a magnolia bush is a simple process that can be done with just a few basic tools. First, you will need to identify the branches that you want to remove. Once you have identified the branches, you will need to use a sharp pair of pruning shears to cut them off. Be sure to make your cuts clean and even so that the plant can heal quickly.

The Propagation

Propagation is typically done through rooting softwood or semi-hardwood cuttings taken from the magnolia bush. Cuttings should be taken from new growth and should be 6-8 inches long. The cuttings should be placed in a potting mix that is moist, but not wet, and should be placed in a shady spot. Cuttings should be checked regularly to make sure the soil is still moist and, after 6-8 weeks, the roots should be well established and the plant can be transplanted into a larger pot or into the ground.

Plant Growth

Usually, the plant growth rate during the spring and summer when the weather is warm and there is plenty of rain. The bush can grow up to 2 meters in a single season. In the fall, the growth rate of the magnolia bush slows down as the weather starts to cool off.

Basic Problems

Common problems for this kind of plant are caterpillars, aphids, and scale. The best way to control these pests is to use an insecticide specifically labeled for the pest you are trying to control. For caterpillars, you can also use a Bacillus thuringiensis (BT) product.
