Proper care in the cool

For any plants wintering at low temperatures, careful inspections are needed, maintaining cleanliness, but most importantly, the correction of irrigation and top dressing. Watering has been reduced since the fall, drying the substrate more and more and adhering to the recommendations for a particular species exactly.

With a full dormant period and leaf dropping, watering is almost stopped, and foliage-preserving plants are watered gently, maintaining light soil moisture and allowing the substrate to dry. Overfilling, dampness, stagnation of water in pallets in the cool are unacceptable. Fertilizing completely stops and does not resume until the beginning of growth and transfer to heat.
