Luffa germinates in four to five days. Luffa, as a summer vegetable, not only tastes delicious, but also can replace sponge to wash kitchen utensils or clean furniture, and even can be used as a medicinal material. The quality of towel gourd seedlings is directly related to the quality and output of towel gourd, so it is very important to raise seedlings. When sowing loofah, we should pay great attention to the quality of seedlings to avoid the occurrence of bad situations in time. The seed coat of loofah is very thick and it is not easy to absorb water, so it is generally necessary to soak the loofah seeds in water with appropriate temperature for about 10 hour, so that the seeds can absorb enough water. Then take the seeds out of the water and put them on a wet cloth. At this time, we must pay attention to the humidity of the cloth, so that no water drops can flow out and it cannot be too dry. We should keep a moderate humidity, put away the seeds and then cover them with a wet cloth with the right humidity. This is to block the direct sunlight on the loofah seeds, and we can sow in the soil for about two days under the shading condition. After the loofah seeds are sown in the soil, it is necessary to maintain a suitable temperature, about 28 degrees. Because the seeds of Luffa need high temperature, special attention should be paid, especially at night, to keep it at a suitable temperature all the time. Luffa seeds will emerge four to five days after sowing in the soil. Don't water after emergence. When the seedlings grow to a certain extent, they can be transplanted. After transplanting the seedlings into the ground, water them as soon as possible so that the seedlings have enough water to grow.
