Cultivation methods and precautions of Phlox

Farming methods

Watering

Potted philadelphus prefers relatively moist soil and air environment. There must be sufficient water supply during the growing period, watering every 1 to 2 days.

It depends on the specific situation. Water thoroughly when the soil is dry. It is okay if the soil is slightly dry, but do not water too frequently to avoid waterlogging and root rot. >

soil

Phlox likes loose, fertile, well-drained sandy loam. Generally, the soil should be changed once every two years in spring. When changing the soil, peat soil can be mixed with one-third river sand.

illumination

Phlox is suitable for growing in a semi-lit environment with bright scattered light. It needs bright light, but at the same time avoids strong exposure to the sun, especially in early summer after a long period of rain, to prevent the leaves from being burned.

Fertilization

The growth of Phlox requires sufficient fertilizer.

During the vigorous growth period of April to June, fertilizer should be applied once every one to two months. For home potted plants, a mixture of 0.2% urea and 0.1% potassium dihydrogen phosphate can be applied. You can also sprinkle or bury a small amount of multi-component slow-release compound fertilizer granules on the surface of the potting soil.

Precautions

Different seasons, different moisture

The temperature is high in midsummer. In addition to sufficient watering, you also need to spray the leaves once a day.

In late autumn and early winter, when the temperature drops below 15℃, control watering.

In winter, you should reduce the amount of water you boil, or use spraying instead of watering, and keep the soil in the pot slightly moist and slightly dry. However, when spraying the leaves, make sure the water temperature is basically the same as the room temperature.

Loosen the soil in time

During the growing season, you can combine fertilization with loosening the soil in the pots once a month to keep the soil in the pots well-ventilated for a long time and avoid root rot caused by soil compaction.

Place the potted plants in a ventilated place

Home potted plants can usually be placed in a well-ventilated place near a south-facing entrance. In summer, they can be placed in front of a north or east-facing window. In winter, they should be placed indoors with better light.

Reasonable fertilization

Stop applying nitrogen fertilizer after Mid-Autumn Festival and apply phosphorus and potassium fertilizers 1-2 times to increase the plant's cold resistance and enable it to survive the winter smoothly.

After winter, the plant has stopped growing and it is necessary to stop fertilizing to avoid damaging the roots.
