Time and Maintenance Methods for Potting旱金莲 (Dahlias)
Today, the editor will explain the timing and maintenance methods for potting dahlias, sharing some related experience in flower planting. Here are the details:
Time and Maintenance Methods for Potting旱金莲
The best time to repot dahlias is between April-May or September-October, avoiding high temperatures and cold periods. If the temperature can be maintained between 15-25 degrees Celsius, repotting can be done throughout the year. Before repotting, keep the soil slightly moist; do not water or fertilize immediately after repotting, and after 7-10 days when the plant has adapted, you can spray it with water.
Timing for Potting Dahlias
If the temperature can be maintained between 15-25 degrees Celsius, repotting can be done throughout the year. However, the optimal time for repotting dahlias is between April-May or September-October, avoiding high temperatures and cold periods, as dahlias will have an acclimation period after repotting.
Methods for Potting Dahlias
Prepare the potting soil: The soil can be mixed in a ratio of 4:1:4:1 using leaf mold, compost, garden soil, and sandy soil. Use a medium-sized porous ceramic or plastic pot to ensure good ventilation and drainage.
Transplanting the plant: First, remove the dahlia from its original pot, clean the soil from the roots, and剪 off any excess fibrous and rotten roots. Remove yellowed leaves and then replant it in new soil and pot without fertilizing or watering.
Precautions for Potting Dahlias
Keep the soil slightly moist before repotting. After repotting, dahlias will have a 2-3 day acclimation period during which you should not water or fertilize immediately. After the acclimation period, you can spray the plant with water.
If overwatering, excessive fertilizing, or unsuitable soil causes the roots to rot, you need to remove the plant from the soil,剪 off the rotten roots, and spray the roots with a fungicide for disinfection, then let it dry in a shaded place for a day.
How to Maintain Dahlias After Potting
After potting, dahlias will usually adapt in about 7-10 days, but if the conditions are not suitable, the adaptation period may be longer.
Watering should be done 2-3 days after repotting, with a moderate amount of water to keep the potting soil moist and to spray the leaves.
Fertilizing should be done half a month after repotting, using phosphorus and potassium fertilizers preferably, and avoiding nitrogen fertilizers to prevent excessive growth and root burns.
For propagation, you can use a seedling tray or a pierced plastic cup. Before propagation, soak the soil thoroughly and then plant. After propagation, place it in a well-ventilated area with scattered light, ensuring the soil is moist but not waterlogged. It usually takes 10-15 days to root.
After the dahlia grows two leaves, expose it to more sunlight, spray water daily to keep it moist, and prevent water deficiency for better growth.
