Causes and treatments for yellowing magnolia leaves

Causes and treatments for yellowing magnolia leaves

1. Too much water

Reason: Plants need an appropriate amount of water to grow. If it exceeds the required range, it will become a burden on their growth. If you water the magnolia too much, water will accumulate, causing root rot and causing larger areas of leaves to turn yellow.

Measures: If the situation is not serious, you can loosen the soil, drain excess water from the potting soil, and increase air permeability. If the situation is serious, you need to dig out the plant, cut off the rotten roots, and apply some growth hormone and rooting agent. Then change the soil and replant it to encourage its roots to grow again.

2. Pest and disease problems

Cause: Magnolia may have partial yellowing of leaves due to the sucking of scabies or aphids and the occurrence of sooty mold.

Measures: It is necessary to find out the source of pests and diseases and take timely measures to control them, and the yellowing of leaves will be alleviated.

3. Natural aging

Reason: Don’t panic when you see the leaves turning yellow. It may not be due to maintenance problems, but just the growth process of its metabolism. It is a natural aging and yellowing.

Measures: Don’t worry about this situation, just let nature take its course and trim the yellow and fallen leaves from time to time.

4. Unsuitable soil

Reason: Magnolia has relatively high requirements for soil. The soil for growing magnolia should be sandy soil with good drainage and slightly acidic properties. If the soil used is alkaline and compacted, it will be very detrimental to its growth and will gradually cause its branches and leaves to turn yellow.

Measures: It is necessary to replace the well-drained, slightly acidic sandy soil in time. Dig out the plant, cut off the roots that may rot, disinfect the roots and new soil, and then replant it.

5. Insufficient nutrients

Reason: Magnolia likes fertilizer, and its growth requires sufficient nutrients through fertilization. If too little fertilizer is applied, the plant will be malnourished and will develop yellow leaves.

Measures: Top dressing is needed in time, do not apply too much fertilizer at one time, just an appropriate amount to slowly replenish the nutrients it needs. In daily maintenance, some compound fertilizer should be applied during the flowering period, and nitrogen fertilizer should be applied once after the flowering period.
