How to Plant Phlox: Detailed Guide to Planting Methods and Precautions

The phlox is native to Mexico and is a flower variety introduced and cultivated in China from abroad; at present, it is distributed quite widely across China. The phlox has high ornamental value, which is why it attracts many people to grow it. However, before planting, most people probably still want to have a thorough understanding of its planting techniques.

How to Plant Phlox

The seeds are relatively small, so they can be sown directly in a seedling tray using a lightweight sowing medium. After sowing, cover lightly with soil; fine-grained vermiculite is often used, which helps keep things moist, and at the same time spray a fungicide to prevent the seedlings from getting diseased. The optimal germination temperature is 20-22 degrees; soil temperature has a great influence on seed germination and should be controlled with extra care. Generally, seedlings can emerge in 7-14 days. In northern regions, sowing can be done in early February, and flowering occurs after May. Cool climate is needed in summer. In the middle and lower reaches of the Yangtze River and areas to the south, because summers are hot, autumn sowing is often used, with seedlings overwintering above 0 degrees, so that they can bloom in spring.

Phlox Planting Methods and Precautions

1. Cultivation methods:

1. Soil. Before preparing to plant, the soil must first be disinfected. If conditions allow, the soil can be sifted through a sieve to clear away larger clods and stones, and then the soil can be reconfigured. The potting soil for planting can be exposed to the sun, or sprayed with an aqueous solution of potassium permanganate, formalin, dexon, etc., mixed in an appropriate ratio, and used after it dries.

2. Germination. Before planting, it is best to treat the seeds first, which can increase the germination rate. The simplest method is to soak them in warm water for 6-8 hours, optionally adding some rooting powder, and then

3. Sowing. After the seeds are treated, scatter them evenly on the soil surface, not too densely, so as not to affect the germination rate. Then cover the soil surface with a 3 mm layer of sandy soil; do not cover with clods of soil, as that is too heavy. Water thoroughly and cover with plastic film to retain moisture. Move it into the sunlight; if you see water vapor all over the plastic film, you can open it for ventilation. They will generally sprout in about 7-10 days.

2. Precautions:

1. Phlox seedlings do not tolerate transplanting. After seedlings grow from sowing, do not keep moving them around. After the seedlings have grown for 4 weeks and their root systems are stable, they can be transplanted into pots. At the beginning, you can choose a small pot of about 10 cm, and after the seedlings grow larger, you can switch to a larger pot.

2. Phlox grows well in an environment with ample sunlight. As long as it is pruned in time, the plant shape is compact and attractive, but if it lacks sunlight, it may become leggy, and it may even grow into a “towering tree.” You can appropriately spray chlormequat to keep the phlox from growing too tall.

How to Care for Phlox After Planting

1. Most wildflowers are the type that blooms brilliantly with just a bit of sunlight, so give them light with confidence. During the growing period, make sure there is ample sunlight; of course, they can also grow in a semi-shaded environment.

2. Phlox does not tolerate high temperatures. When the summer temperature is above 35°C, obvious yellowing of the leaves will appear. Appropriate shading is needed to avoid direct sunlight, and water can be sprinkled to lower the temperature. Phlox is cold-tolerant and can overwinter outdoors in winter, but in some areas where winter temperatures are too low, it is recommended to move it indoors to overwinter.

How to Prune Phlox

1. Spring, when all things revive, is the best time for pruning. In spring, as the temperature warms, new shoots sprout, and the branches and leaves can be cut back. Keep branches in suitable positions that are robust as the retained branches, and cut off all the other branches. The main purpose of such pruning is to control the height of the plant and ensure a perfect plant shape with abundant flowers and lush leaves. Note that after cutting back, nutrients should be replenished in time, applying a dilute liquid fertilizer once two weeks later. After fertilizing, water in time and loosen the soil appropriately to ensure good soil permeability. In this way, the phlox will bloom continuously from summer to autumn.

2. In autumn, the flowers fade and the fruits are harvested. Phlox generally begins blooming in August, and this continues until early October, so after the flowers fade, the flowering branches should be cut off in time to reduce nutrient consumption and ensure flowering the following year. If they are not pruned in time and are allowed to fall off naturally, it may lead to insufficient nutrients for the plant and may even induce pests and diseases.

The planting method for phlox is actually not difficult. Before planting, you need to do a good job of selecting the site and preparing the soil ratio, and then choose a suitable time for planting. After planting, care should be strengthened; timely shading and pruning are both essential conditions for ensuring its growth.
