Why are the edges of strawberry leaves turning yellow and drying up?

Strawberry is one of the fruits that is particularly suitable for home potted plants. It does not take up space and bears a lot of fruit. The most important thing is that you don’t have to worry about hormones when you grow it yourself, so you can eat it with more peace of mind. However, during the strawberry planting process, the edges of the leaves often turn yellow and dry. So what’s going on with the yellowing and drying of the edges of strawberry leaves? Let’s take a look below.

1. Why do the edges of strawberry leaves turn yellow and dry?

1. Calcium deficiency causes new leaves to dry up

When calcium is deficient, new leaves turn yellow, the leaf edges lose water, and then dry up and turn brown. Calcium has low mobility in the plant body and is mainly concentrated in older tissues. It is rarely transported to young organs. Therefore, strawberries are very prone to calcium deficiency symptoms such as dry leaf tips.

Strawberries require more calcium and mainly absorb calcium ions. At the same time, strawberries have a high demand for calcium, which can easily cause calcium deficiency. Calcium ions easily react with sulfate, phosphate, and carbonate in the soil to produce precipitation, which cannot be absorbed by the plants. This causes the strawberries to still be calcium deficient even after fertilizer has been applied.

Solution:

(1) If the strawberries are already calcium deficient, spraying calcium on the leaves is more effective than flushing it through the roots, so foliar spraying is recommended.

(2) You can choose calcium, boron and magnesium foliar fertilizer and spray it once every 7-10 days for 2-3 times in a row.

2. Fertilizer damage causes dry edges

If the leaves begin to dry up from the edges and wither soon after fertilization, it may be due to excessive fertilization, high soil salt content, and difficulty in root absorption, causing the plant to lose water.

When the damage is mild, the leaves will begin to turn brown from the edges, and in severe cases, they will become scorched and spread to the middle.

Solution:

(1) Apply fertilizer in small amounts and multiple times. Strawberry is a crop that is not tolerant to fertilizers. Remember to apply a large amount of fertilizer at one time. 5-10 catties/mu for ground planting and 3-5 catties/mu for substrate cultivation.

(2) If seedling burn has occurred, stop fertilizing for 1-2 times and use clean water to dilute the salt in the soil to alleviate the damage caused by fertilizer damage. 3. Bihu + Green Duomei or Bihu + Duomei foliar fertilizer can be used to repair the losses caused by fertilizer damage. At the same time, some seaweed-based root-promoting fertilizers can be applied to help restore growth in time.

2. How to grow strawberry potted plants in summer?

1. Light and temperature: Strawberry plants prefer a sunny environment, but during the hot summer months, overexposure to strong sunlight may cause leaf burn. During hot afternoon hours, provide some shade for your strawberries to avoid excessive heat and light. The ideal temperature range for strawberry growth is 15°C to 25°C.

2. Watering: In the hot summer weather, strawberries need sufficient water to maintain growth and fruit development. Keep the soil moist, but avoid overwatering. Water in the morning or evening to prevent the water from evaporating quickly in the sun. Make sure the soil drains well and avoid standing water.

3. Mulch: During hot summer months, consider placing mulch, such as grass clippings or straw mats, around your strawberry plants to help keep the soil moist and lower soil temperatures. Mulch also reduces weed growth and keeps the fruit cleaner.

4. Cut off buds and fallen leaves: Check the strawberry plants regularly and cut off overgrown buds and damaged leaves in time. This helps provide good ventilation and reduces the risk of pests and diseases.

5. Fertilization: During the summer growing period, strawberry plants need an adequate amount of nutrients. You can use organic fertilizer suitable for strawberries or special strawberry fertilizer and apply appropriate amount of fertilizer according to the instructions on the package.

6. Pest and disease control: High temperatures and humidity in summer may increase the risk of strawberry plants becoming diseased or infested by insects. Check the plants regularly, especially the leaves and fruit, and take care to treat any infected parts or pests you find. Organic control methods or organic pesticides can be used for control.
