Cause: lack of nutrients in pot soil will lead to poor growth of passion fruit, which will make its leaves yellow and atrophic.
Solution: fertilize the passion fruit properly. Generally, the lack of nitrogen and potassium fertilizer will cause yellow leaves, but the situation is slightly different. If the plant is thin and weak, it is often caused by nitrogen deficiency. If the edge of the leaf is yellow, it is caused by potassium deficiency. Can apply a little compound fertilizer, comprehensive supplement nutrition.
Reason: passion fruit is suitable to grow in sufficient light environment. Too much shade will lead to poor growth, which will make the leaves yellow.
Solution: move the passion fruit to the sunny place, with no less than 8 hours of light per day. Because it is not afraid of strong sunlight, it does not need to be shaded. Sufficient light can not only make the plant grow well, but also contribute to the development of fruit.
Cause: over watering or over concentration of fertilizer will lead to root rot of passion fruit, affect its ability to absorb water and nutrients, and cause yellow leaves.
Solution: take the passion fruit out of the basin, and remove part of the old soil to expose the root. Check if there is any rot and cut off the rotten roots in time. After that, put it in the carbendazim solution and soak it. After a period of time, take it out and put it in the shade. Dry plants should be replanted with dry soil to avoid the recurrence of rotten roots.
Cause: no watering for a long time or too little water, resulting in no water absorption at the root, causing yellow atrophy of the leaves
Solution: water the passion fruit in time. Although it has certain drought resistance, but long-term water shortage will lead to poor growth. Generally, after the soil is dry, make up water immediately, and the amount of water should be sufficient, but it can't form water.
