How to grow Phlox drummondii? A complete guide to cultivation methods and things to note

Phlox drummondii, also known as dwarf phlox, annual phlox, and Drummond's phlox, is an annual herbaceous plant in the genus Phlox of the family Polemoniaceae. It is cultivated in gardens across China. The plant is short and compact with rich flower colors, and can be used as planting material for flower beds, flower borders, and rock gardens, as well as potted plants for indoor decoration. Taller varieties can be used as cut flowers. Let's take a look at the cultivation methods and things to note for Phlox drummondii!

Growth habits of Phlox drummondii

Phlox drummondii is native to Mexico and is cultivated in gardens across China. It likes light and tolerates cold, prefers a mild and humid climate, and does not tolerate extreme heat or hot weather. It prefers well-drained, loose soil, does not tolerate drought, and dislikes waterlogging and saline-alkaline conditions. In poor yellow sandy soil, it can still survive and grow even without rain for many days. In the North China region, it can overwinter in cold frames.

Propagation methods of Phlox drummondii

Phlox drummondii is usually propagated by sowing seeds. First, sterilize the prepared seedbed soil using potassium permanganate, formalin, dexon, or similar, mixed into an appropriate ratio of aqueous solution and sprayed onto the seedbed. The seedbed soil should be sifted through a fine sieve and the bed leveled, then watered thoroughly. After the water drains, evenly scatter the seeds on the seedbed. There are 750 seeds per gram. It is best to pre-germinate the seeds before sowing. After scattering the seeds, evenly sift the prepared sandy soil over the seedbed with a soil cover thickness of 0.3 cm, then cover with plastic film or a hoop-style tunnel. After about 7 to 10 days, they will germinate and become seedlings.

Cultivation methods of Phlox drummondii

1. Watering: During the growing period, Phlox drummondii needs sufficient water, and the potting soil should be kept moist. However, because the leaves are quite dense, do not water directly from the top to avoid water accumulating on the leaf surface. In rainy seasons, it can be exposed to some rain, but make sure to drain promptly to prevent pests and diseases.

2. Fertilizing: During the growing period of Phlox drummondii, especially after pinching and pruning, promptly apply diluted liquid fertilizer to promote branch growth and flowering. Phlox drummondii is relatively sensitive to nitrogen fertilizer; excessive nitrogen will burn the seedlings to death. So when fertilizing, apply more phosphorus and potassium fertilizer and less nitrogen fertilizer.

3. Temperature: Phlox drummondii does not tolerate high temperatures. When summer temperatures exceed 35°C, obvious yellowing of leaves will occur, so appropriate shading is needed to avoid direct sunlight. However, Phlox drummondii is cold-tolerant and can overwinter outdoors, but in some areas where winter temperatures are too low, it is recommended to move it indoors for the winter.

4. Pruning: When Phlox drummondii grows to about 15 cm, pinch once by removing the top to promote branching and control plant height, ensuring a short, sturdy, and full plant shape. After flowering, prune off the stems and spent flowers as soon as possible and appropriately thin the branches to ensure new shoots can sprout and bloom a second time.

Things to note for Phlox drummondii

1. The seedlings of Phlox drummondii do not tolerate transplanting. After seedlings grow from sowing, do not move them around. After 4 weeks of growth, when the root system is stable, they can be transplanted into pots. At first, use a small pot of about 10 cm, and after the seedlings grow larger, they can be moved to a larger pot.

2. Phlox drummondii grows well in a sunny environment. 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 could even grow into a “towering tree.” You can appropriately spray chlormequat to keep Phlox drummondii from growing too tall.

How to grow Phlox subulata? Cultivation methods and things to note for Phlox subulata

Phlox subulata is also called moss phlox or creeping phlox, and belongs to the genus Phlox of the family Polemoniaceae. It is a perennial herbaceous plant native to North America and is now relatively common in various places. It is often used for environmental greening and is the best ground cover plant to replace traditional lawns. So let's learn together about how to grow Phlox subulata and its cultivation methods and things to note!

How to grow Phlox subulata, cultivation methods and things to note for Phlox subulata:

1. Growth habits: Phlox subulata is an annual or biennial herbaceous flower. It likes light, tolerates cold, prefers a mild and humid climate, and does not tolerate extreme heat or hot weather. It prefers well-drained, loose soil, does not tolerate drought, and dislikes waterlogging and saline-alkaline conditions. It is understood that Phlox subulata can still survive and grow in poor yellow sandy soil even without rain for many days.

2. Watering and fertilizing: Phlox subulata grows robustly and can also grow well in slightly dry soil. Phlox subulata has no strict requirements for fertilizer, but during the growth cycle, growers should pay attention to applying base fertilizer. When preparing the land, add organic fertilizer, applying about 500 kg to 1000 kg per mu. When Phlox subulata enters the growing period, appropriately apply a small amount of nitrogen and phosphorus fertilizer. During the leaf-growing stage, nitrogen fertilizer should be the main type, and during the flowering stage, phosphorus fertilizer can be sprayed.

3. Pruning: It is understood that Phlox subulata should be pruned promptly in summer, and after flowering is the best time for pruning. The branches and vines that have already flowered and the weak, underperforming branches and vines should be cut off. At the same time, if growers find weeds, they should remove them manually, which can effectively improve the ornamental value of the plant.

The above is how to grow Phlox subulata and its cultivation methods and things to note. It not only has a high coverage rate but also strong ornamental value. It is an excellent ground cover flower and a good ground cover plant, used to accent lawns or plant in hanging baskets.
