If you noticed some abnormal changes to your plants, then there is something wrong. How will you determine what is wrong with your plants just by looking only at their leaves?
- When you noticed that the lower leaves turn yellow from outside going in and the veins remain green, then turn to red or purple that means your plant has magnesium deficiency. If the deficiency is serious, the leaves will become brown and brittle and it will fall on the ground. To fix this, spray the foliage with an Epsom salt solution. Mix 1 cup of Epsom salts with a gallon of water and spray the plant thoroughly. You must repeat this weekly until the symptoms disappear. But remember, this is just a quick solution because the real problem of your plants magnesium deficiency is your soil. You need to feed your soil with magnesium.
- Leaves with yellow spots and or elongated holes beween veins is a sign that your plants need manganese. The symptoms is similar to magnesium because manganese is involved in photosynthesis. Manganese deficiencies occur most often on soil with a high pH. To fix this problem, a foliar feed fertilizer with manganese will help alleviate the issue. You may also lower the soil pH.
- When the upper leaves of your plant are light green where lower leaves are yellow and the bottom or older leaves are yellow and shrivelled, your plant needs Nitrogen. To fix the deficiency, organic mulches of various materials including foliage from leguminous trees and animal manure may be used to provide nitrogen to the plant.
- If the tips and edges of your plant is yellowing, especially the younger leaves, and the dead or yellow patches develop on leaves, then your plant needs Potassium. To fix this deficiency, you may add wood ash on your soil but make sure you apply it lightly, as too much can burn your plants. If you have no woodash, banana peel can be used to improve your soil’s potassium content.
- When leaves are darken than normal and the plants began losing its leaves, your plant needs Phosphorus. To fix the phosphorus problem in your plant, add plenty of organic matter to the soil before, during, and after the season. Garden humus includes phosphorus. You may also add rock phosphate to your compost pile to ensure the nutrients’s availability for next season.
- Your plant need calcium when you noticed curling of leaves or necrotic leaf margins on young leaves, and eventual death of terminal buds and root tips. Calcium deficiency affects the new growth. Soving calcium deficiency is one of the easiest problems to fix. You can use lime, gypsum, bone meal, egg shells and even just watering your plants can fix calcium-deficiency in your plants. Using bone meal can be used if you have a very serious calcium deficiency problem. It has one of the highest calcium contents and suited to all types of soils.
