How long does it take for sunflower cuttings to take root? Why do sunflower cuttings cause root rot?

1. How long does it take for cuttings to take root?

It is relatively easy for sunflower cuttings to take root. As long as the timing and method are correct and attention is paid to management after planting, the plants will generally take root in about half a month. The time for planting should be between May and August. When planting, choose strong branches and do not bury them too deep in the soil, a depth of two centimeters is enough. After planting, water thoroughly, spray water frequently to keep it moist, and ventilate it more often. This way, it will definitely take root in about half a month.

2. What is the problem of root rot in cuttings?

1. Excessive watering: It is very drought-resistant and does not require frequent watering during maintenance. The seedlings that are rooted by cuttings are very weak in the early stages and do not have a high demand for water. If you water a lot at this time, it will be difficult to absorb. Over time, water will accumulate, hindering the normal breathing of the roots and causing root rot.

2. Improper fertilization: Whether it is a seedling from cuttings or a seedling grown from seeds, the nutrients consumed during the seedling stage are limited and no fertilization is needed. If fertilizer is applied at this time, the plant will not absorb it, but will burn the roots and cause root rot.

3. Management of cutting seedlings

When caring for the rooted seedlings from cuttings, pay attention to light and avoid strong light to avoid burns. Just face the morning sun every day, and avoid it at noon. You don’t need to water too frequently. Just water when you find the soil is dry. Be careful not to overwater. Also, pay attention to the temperature aspect. It should be maintained above 18 degrees, not too low. Ventilate more when the temperature is high, and resume normal management after the seedlings have grown steadily.
