When is the most suitable time to plant leaf lettuce?
Every vegetable has its own unique growth pattern. Take Chinese cabbage, for example: most of it is planted in autumn and winter and harvested in winter and spring, while water spinach, amaranth and the like are planted in late spring and harvested in summer and autumn. Leaf lettuce is also a kind of vegetable. So what exactly is its growth pattern? ⟦4 <p>Every vegetable has its own unique growth pattern. Take Chinese cabbage, for example: most of it is planted in autumn and winter and harvested in winter and spring, while water spinach, amaranth and the like are planted in late spring and harvested in summer and autumn. Leaf lettuce is also a kind of vegetable. So what exactly is its growth pattern?</p><p><strong></strong></p><p><strong>Planting time for leaf lettuce</strong></p><p>Leaf lettuce is generally sown in August-September, but with the development of greenhouse technology, it can now be planted all year round.</p><p></p><p><strong>Seedling-raising techniques for leaf lettuce</strong></p><p>1. Seed treatment: To raise leaf lettuce seedlings, the seeds need to be soaked to promote germination. Wrap the seeds in gauze and soak them in cool water for about 1 hour, then take them out and place them at 15-20℃ or in a household refrigerator's cold storage compartment for 2-3 days. Once the seeds show white sprouts, they can be sown.</p><p>2. Seedbed preparation: Choose a seedbed plot where the previous crop was not treated with long-residual herbicides such as imazethapyr or thifensulfuron-methyl, with high, dry terrain and strong water- and fertilizer-retention capacity. Apply plenty of organic fertilizer. For each mu of cultivation field, use 15-20 sq m of seedbed.</p><p>3. Timely sowing: At sowing time, mix an appropriate amount of fine sand with the seeds to separate them, then broadcast them to raise seedlings. Do not sow too densely, to prevent the seedlings from becoming leggy. Cover the seeds with 0.5 cm of medicinal soil mixed with phoxim, and set up a shed for sun protection and rain protection.</p><p>4. Seedling-stage management: When the leaf lettuce seedlings grow two true leaves, divide the seedlings, with a transplanting density of 6×6 cm. The leaf lettuce seedbed should be kept moist, and shade should be provided at noon. At the same time, during the seedling stage, leaf lettuce requires attention to pest and disease control.</p><p><strong></strong></p><p><strong>Field management techniques for leaf lettuce</strong></p><p>Leaf lettuce is generally cultivated in flat beds. Leaf lettuce can be planted out once it has 5-6 true leaves, with a row spacing and plant spacing of about 20 cm. Before planting out, deep-plow and apply sufficient base fertilizer. Generally, apply 3000 kg of decomposed barnyard manure per mu, 80-100 kg of ammonium bicarbonate, with 2 m including the ditch, deep ditches and high beds. Plant out at the 4-5 leaf stage, with strong seedlings, at a row spacing and plant spacing of 10-15 cm, cultivated in flat beds. For spring sowing and open-field transplanting, apply sufficient decomposed barnyard manure, and apply 80 kg of ammonium bicarbonate per mu.</p><p>After planting out, water thoroughly to settle the roots. In case of drought, promote growth with fertilizer and water, and it can be marketed in 25-30 days, with a yield of 1800-2000 kg per mu. Autumn sowing in July-September coincides with the high-temperature and dry season, and there are often rainstorms. After transplanting, water thoroughly to establish the plants, and cover with shade netting for 5-7 days. After the plants are established, if there is cloudy and rainy weather, the shade netting can be removed. Moderate fertilizer and water are conducive to the normal growth of leaf lettuce, and it can be marketed in 20-30 days, with a general yield of 1600-1800 kg per mu. For autumn-winter sowing in October-November, transplant in the open field. If a cold wave hits in December, it needs to be transplanted into a greenhouse, and it can be marketed in 25-30 days, with a yield of about 1500 kg per mu. Before planting out, apply sufficient base fertilizer. For every 667 mz, apply 5000 kg of high-quality barnyard manure, 40 kg of diammonium phosphate, 20 kg of urea, 20 kg of potassium sulfate, or 200—300 kg of plant ash, and make beds 1.5 m including the ditch.</p><p></p><p>When planting out, water well with the planting water. After 1 week, water thoroughly to help the seedlings recover. After recovery, apply a seedling-promoting fertilizer together with watering (15 kg of urea). In the later stage, apply a heavy plant-promoting fertilizer (30 kg of urea). After planting out and recovery, carry out timely intertillage and deep hoeing to help the plants stay compact and promote root development. Throughout the entire growth and development period, keep the field moist and the soil loose. The management method after planting out is basically the same as that for celtuce, and fertilizer and water management must be strengthened. It is necessary both to maintain sufficient moisture and to prevent waterlogging damage caused by excessive moisture, while also doing a good job of pest and disease control.</p><p></p><p><strong>Harvesting and storage of leaf lettuce</strong></p><p>Harvest. After planting out, depending on various conditions, it can be harvested in about 30-50 days, and in winter it takes a little longer. For harvesting, in summer it should be done in the morning, and in winter in a greenhouse it should be done in the evening. A knife can be used to cut the plant close to the ground. Remove yellow leaves and diseased leaves, then tie them into bundles or put them in baskets for sale. If long-distance transport is required, precooling is also necessary, or ice cubes can be placed in the packing boxes (frost damage is likely to occur around the ice cubes).</p><p>Storage The suitable storage temperature for leaf lettuce is 0℃, and the suitable relative humidity is above 95%. For storage or transport, the quality of the leaf lettuce must be high, the leaves should not be too tender, and the moisture content should be low. When harvesting, handle gently, harvest gently and place gently, to avoid mechanical damage.</p><p></p><p>In today's era of highly advanced technology, leaf lettuce can be planted all year round, but like all vegetables, vegetables grown in accordance with the laws of nature always taste better than those grown by breaking the rules. So, if it is for your own consumption, then do the appropriate things in the appropriate season!</p>

Causes and Solutions for Leaf Drop and Black Spots on the 'First Love' Succulent
The 'First Love' succulent is a common variety of succulent plant, and it can now be seen in many places across our country. Because of its attractive appearance, many people grow it at home. But have you ever experienced the trouble of leaf drop while growing it? In fact, this ⟦4 <p>The 'First Love' succulent is a common variety of succulent plant, and it can now be seen in many places across our country. Because of its attractive appearance, many people grow it at home. But have you ever experienced the trouble of leaf drop while growing it? In fact, all of this is caused by not mastering the proper techniques.</p><p></p><p><strong>Causes of leaf drop in the 'First Love' succulent</strong></p><p>1. Overwatering. Some succulent growers cannot control their hands, and whenever they see the plant looking a bit dry they keep watering it, which leads to excessive moisture and causes the leaves to fall off at the slightest touch. In this situation, you must pay attention to watering at ordinary times. Generally, watering thoroughly after the soil has dried out is enough; just do not let water accumulate in the pot.</p><p>2. Lack of light. Sometimes when the plant lacks light for a long time, the leaves will also fall off at the slightest touch. The best solution in this case is to give it more sun at ordinary times, but in summer be careful not to let it get sunburned; some plants need shading.</p><p>3. Root rot. Leaves falling off at the slightest touch is sometimes caused by a problem with the plant's root system. At this time you can take the plant out of the pot to check whether the roots have a problem. If there is a problem, use a sterilized knife to cut off the rotten roots, then apply some carbendazim powder to the wounds, let the wounds dry, and then repot.</p><p></p><p>4. Soil and pot that do not breathe. Apart from the four situations above, leaf drop is sometimes caused by soil and pots that do not breathe. Poorly aerated potting soil often leads to weak roots, and at this time you should replace the soil and pot promptly.</p><p>5. Pests. If your plant is being troubled by scale insects or root mealybugs, then leaf drop is almost certain to happen, so pay attention to timely prevention and control of common succulent pests.</p><p>6. Normal metabolism. This one is relatively easy to judge. In this situation, mostly only the bottom leaves fall off, and new leaves are growing; the new leaves are not wrinkled and do not fall off easily. In this case there is no need to worry; the consumption shows that the plant is growing.</p><p></p><p><strong>Solutions for leaf drop in the 'First Love' succulent</strong></p><p>1. For 'First Love', the soil mix is generally one part peat + one part vermiculite + one part perlite, with an appropriate amount of bone meal added. You can also use a mix of 3 parts leaf mold, 3 parts river sand, 1 part garden soil, and 1 part cinder. During the growing season, water thoroughly after the soil has dried out. When the air is dry, you can sprinkle water around the plant, but water should not accumulate on the leaf surface, especially in the center of the leaf rosette, otherwise it will cause heart rot.</p><p>2. 'First Love' likes a warm, dry, and ventilated environment, likes light, is drought-tolerant, cold-tolerant, and tolerant of partial shade. Its main growing seasons are spring and autumn. Water thoroughly after the soil has completely dried out, and reduce watering in summer.</p><p>3. For a glass pot, watering once every half a month is enough. The plant's roots have already partially rotted, affecting the supply of nutrients and water. Now the more you water and the more you expose it to the sun, the greater the plant's transpiration, and this vicious cycle will eventually lead to the death of the whole plant. Pots with a substrate that does not breathe should have drainage holes; water less and give more light.</p><p>4. 'First Love' has no obvious dormancy period. In winter, it is best to place it indoors in a sunny spot for care.</p><p>5. If it really cannot be saved, then use the relatively healthy fallen leaves for leaf propagation. If almost all the leaves have fallen off, you can also behead it for cutting propagation.</p><p></p><p><strong>What to do if the 'First Love' succulent develops black spots</strong></p><p>The weakness of black spot disease is that it fears high temperatures and fears dryness. Directly place the affected plant in the sunlight, keep the environment relatively dry, and expose it to strong sun for a period of time. Spray fungicide promptly until it improves. In care, also note: do not use soil that has not been disinfected and sterilized; keep the growing environment ventilated; when the rainy season comes, never let it be rained on at will (this point is very important); and never let the potting soil stay wet for a long time.</p><p></p><p><strong>Causes of black spots on the 'First Love' succulent</strong></p><p>If you are not careful in daily care and water directly onto the leaves or the leaf center, water will accumulate for a long time. A stuffy, unventilated environment, especially the stuffy heat of summer, breeds various bacteria. Once 'First Love' develops black spots, it is also rather troublesome to deal with, and there is only a 50% chance of recovery. So during care you must pay attention to them at all times. Please do not casually discard the sick succulents around you; work hard to save them.</p><p></p><p>The causes of leaf drop in the 'First Love' succulent are generally root rot, too little light, pests, and overwatering. If leaf drop occurs during your growing process, you can observe the cause and eliminate this phenomenon at its root. The 'First Love' succulent may also develop black spot disease during growth, and you need to prevent and control it promptly.</p>
