Yellowing is the most common problem faced by eggplant gardeners. The yellowing process occurs both in plants that grow in greenhouses or open grounds. Let’s find the solution for yellow eggplant leaves.


  • Due to Change: The most harmless cause behind the discolouration of green plants is a change of place. When seedlings are planted in the garden soil, they may turn yellow. It takes time for them to adjust to the new soil. This problem goes away after a few days.
  • Leaf Mosaic: the most common disease found in plants is leaf mosaic. It occurs for many reasons ranging from lack of water to lack of fertilizers. If the plant is affected by this problem, the leaves dry out and become yellow. Eventually, they fall off. The fruits also turn hard from outside and become inedible.
  • Soil Type: Eggplants grown in greenhouse often turn yellow because of the soil used. Peat soil turns eggplant foliages yellow and wilt. To avoid eggplant leaves turning yellow apply loam or sand loamy soil.
  • Fusarium: Fusarium is a deadly disease. It weakens the vessels of the leaves. It can easily destroy the whole tree if it gets unnoticed. At first, vessels dry up then the leaves. The leaves then fall off and the shoots follow.
  • Verticulosis: Verticulosis welcomes wilting and yellowing through the entire life cycle of eggplant trees. As mentioned before eggplant leaves are very sensitive. A little more fertilizer can cause Verticillosis. Eventually, if the nitrogen and organic compounds are not regulated the leaves turn yellow and dry up.
  • Fungus infection: Another fungus attacks the eggplant trees that work the same way like Fusarium. But it is a little different than that. This fungal infection first sits on the ground for several days. Then it gradually starts to affect the trees. Moreover, the whole tree including leaves gets covered with yellow spots. This pathogen occurs in open grounds and also in greenhouses. It dries up the whole tree slowly. The tree becomes stunted.
  • Burns: Yellowness can also occur from scorching sunbeams. If you live in a very hot climate then you must protect your trees from very hot sunlight.
  • Seedlings: If none of the above-mentioned problems is present and still your trees are a little bit discoloured, then the problem occurred from the seedlings. Check thoroughly if your seedlings are fresh and green when you plant them to avoid this.


  • Buy seeds from trusted local farmers who supply good eggplant in the market. You can also buy good quality seeds from supermarkets.
  • Disinfect the seeds before planting. Choose the right soil for the seedbed. Also, choose a sunny area.
  • Apply Trichomerdin to the planting holes to prevent your saplings from fungus attacks. Always remember prevention is better than cure.
  • Consult with some experienced eggplant gardeners and apply the right amount of fertilizer to your plant routinely. Use compost and organic fertilizers filled with the right amount of nitrogen.
  • Maintaining good irrigation is very important. Eggplant trees should be watered regularly in the morning and evening hours. Use room temperature water for irrigation.
  • In a bed of seedlings if even one is infected remove it immediately. Stop the spreading in the beginning.
  • Check your plants for disease every day. If any symptoms are found then start to treat it right away.
  • Regularly turn and loosen the topsoil. Check for weeds. Remove any affected soil and weeds.

Why Egg Plant leaves Curling?

  • Inappropriate water: Water is very essential for eggplants. Eggplant trees demand a high amount of water. If the natural water requirement of eggplant trees is not met then several signs occur. One such deformation of the tree along with stunted growth is the curling of leaves. These plants need heavy watering no less than three times a week. Also, topsoil needs regular checking. If the topsoil is dry you should immediately water the plant. Apply settled water stored in room temperature for the good health of the tree. If seedlings are not looking very fresh there must be a water shortage.
  • Shortage of lighting: The problem of eggplant leaves curling may also be caused by insufficient sunlight. The seedlings should stay in sunlight for almost the full day. Then it should be moved into a shade. But the plant always needs more than 8 hours of lighting. Insufficient sunlight does not allow the tree to make enough food.

Always remember to place your garden bed in a position where the sun shines throughout the whole day.
  • More salt in soil than required: If the soil is saltier than required, It becomes hard for the tree to suck the water out of the soil. Trees depend on osmosis. So the salty water welcomes an adverse situation that becomes a problem for the tree.
  • Parasites: Spider mites can also make the leaves curl. If your eggplant leaves are curling, check the seedlings very carefully in a good source of light. You may use a magnifier and a flashlight and try to find the mites. If you find the mites don’t worry, the solution is very simple. Just make some soapy water with some added garlic juice. Then apply the solution with a piece of cloth on the leaves. You may also apply drugs on parasites like spider mites.
  • Deficiency of minerals: Mineral deficiency might be the most ignored cause of eggplant leaves curling. Among many minerals, if the eggplant tree suffers from a deficiency of nitrogen, phosphorus, magnesium and potassium, it may lead to curling of the leaves. However, a little bit of fertilizer can fix this problem. But always be cautious, If you apply too much fertilizer the same problem will occur but in another way. Eggplant leaves wilt, curl and dry to remove the excess fertilizer from the plant. so be wary of how much fertilizer you are applying. Try to use compost for fertilizing.
