Detailed Explanation of Planting Methods and Techniques for Potted Loofah
Potted vegetable gardening is the first choice for many urban farmers, but usually it involves small vegetables like baby bok choy. Some people have also successfully grown loofah in pots on balconies. Growing loofah on a balcony not only provides a vegetable but its vines can also beautify the balcony, truly killing two birds with one stone, and it is also very easy to grow. Let us take a look at the planting methods for potted loofah!
Planting Container
Potted loofah requires a sufficiently large container. The larger the volume and depth of the planting container, the better. At minimum, ensure a soil layer thickness of 15 cm and a soil capacity of 10 liters or more. Only in this way can the later growth of the loofah be guaranteed. Then find suitable soil, add compound fertilizer and mix thoroughly, or directly purchase nutrient soil. Because flower pots are limited, fertile soil is a powerful factor for giving loofah the strength for later growth.
Planting Space
Loofah differs from other vegetables in that it needs to climb vines, so before planting loofah, reasonable planning of the balcony is needed, and preparations for loofah vine climbing and trellising should be made. Because balcony layouts differ, gardening enthusiasts can freely use their creativity, as long as the loofah has somewhere to climb. In addition, pay attention to light and ventilation, which are very important.
Seedling Raising Methods
1. Place seeds in 60°C hot water and stir continuously, soaking for 10-15 minutes, then soak seeds in 30°C warm water for 2-5 hours. After washing, wrap in a wet cloth (or paper towel) and germinate at 25-30°C for 24-36 hours. Sow when 2/3 of the seeds have sprouted white.
2. Sow seeds into disposable plastic cups, cover with 1-2 cm of soil, and water thoroughly. They can also be sown directly in the corresponding container, with 2-3 seeds per hole. At suitable temperatures, germination takes about 5-7 days. At lower temperatures, cover with film to keep warm.
3. Water appropriately after sowing. When there are 4-6 true leaves, transplant on a sunny afternoon. One week before transplanting, ventilate to harden the seedlings. Apply sufficient base fertilizer (for summer sowing, less or no fertilizer can be applied). Remove old, weak, and diseased seedlings, planting 1 plant per pot.
Daily Management
1. Loofah prefers strong light and requires no less than 8 hours of light per day. It tolerates high temperatures but fears cold. The suitable growth temperature is 25-30°C, and the minimum temperature should not be below 12°C. At high temperatures, it still grows vigorously when water and fertilizer are not lacking. It tolerates moisture and needs sufficient water. When temperatures are low, water before noon on sunny days. During drought, water once every other day. During summer high temperatures, water once in the morning and once in the evening.
2. When the loofah plant is about 50 cm tall, mound soil and press the vine once. When it reaches about 70 cm tall, mound soil and press the vine again. Coil the vine on the soil surface and remove side vines. Pruning should generally be done on sunny afternoons. When female flowers begin to appear, set up supports and guide the vine onto the trellis in a "zigzag" shape, tying it with string at intervals of about 20 cm to secure it.
3. Before the loofah sets its first fruit, all side vines should be removed. Afterward, if there are too many side vines for harvesting, remove some of the overly dense or weaker side vines. After side vines set 2-3 fruits, pinch off the growing tips. In the middle and late growth stages, appropriately remove yellow leaves and old leaves, with the principle that leaves do not overlap and block light. During growth, it is best to promptly remove tendrils, most male flowers, and poorly developed fruits. If necessary, manual pollination can be done, generally at 5-6 PM using male flowers that opened on the same day for pollination.
4. Before fruiting, apply decomposed organic fertilizer once every 10 days, for a total of 2 applications. Avoid applying excessive nitrogen fertilizer. After fruiting, apply decomposed organic fertilizer once a week. After flowering, fruits can be harvested in 10-14 days, when the flower at the tip begins to dry up, the skin color begins to darken, and the fruit feels elastic when held. If saving seeds, wait until the skin turns yellow before harvesting.
