Perennial paniculate phlox begin to delight with their gorgeous flowering in July. However, it happens that plants have gained flower mass, but suddenly their stems and leaves began to wither, turn yellow.
This "nuisance" always coincides with prolonged dry and hot weather. If the plants are not helped at the right time, then phloxes will not give their aromatherapy and flowering, but simply dry up.
Causes of yellowing and falling leaves in phlox
Growing plants, many growers do not delve into the intricacies and features of their green pets. Some just planted flowers and happily forgot about them. Phlox, although they belong to perennial unpretentious plants, sometimes they need the slightest care. The yellowing of the leaves is a plea for help. In this situation, flowers only need to "drink" water.
Phloxes have a superficial root system, which is located in a 15-centimeter layer. The roots cannot get life-giving moisture from the deeper layers of the soil. Second point: phloxes have one more feature. In them, growth buds are also formed in the surface layer. "Young people", growing up, begin to crowd out the "older generation". Now food and moisture are needed in double the amount.
How to help phlox
Watering is a must when dry and hot weather sets in. Plants are watered in the evening, adding at least 15-20 liters of water per 1 sq.
Mulching is also required. This is done in order to retain moisture and prevent overheating of the root system. And mulching with humus also serves as an additional food.
After each watering or rain, you need to carefully loosen the top layer of the soil, at the same time freeing the plants from weeds.
What to do to make phlox bloom
Since paniculate phlox grow annually and begin to "stick out" from the ground, it is worth planting them regularly. Phlox should not be planted in the sun.
These perennials do not like dense planting. They bloom well and are less sick with fungal diseases in blown places.
Plants remain "dwarfs" without watering, their inflorescences become smaller. It is better to tie up high varieties so that in a strong wind the plants are not uprooted from the ground.
