How to Save Loofah Seeds? A Detailed Guide to the Latest Seed-Saving Methods
Loofah is an annual vegetable. Except for some hybrid varieties bought from the market, which cannot be saved for seed on your own, generally loofah grown locally can be saved for seed and planted again next year. Saving seed also involves certain particularities and has its own procedure. Generally, you must decide which gourds to select, when it is suitable to begin growing them for seed, when to pick the gourds and extract the seeds, how to handle the seeds after extraction, and how to store them well. Only when all these tasks are done properly can you ensure the seeds will sow smoothly next year. So now let's go find the answers in the article!
1. Selecting the Gourds
In the middle stage of fruiting, that is, when the most gourds are being produced, you should select some loofahs that are disease-free, dark in color, larger in size than those growing at the same time, not deformed, and growing normally, to cultivate as seed gourds. After selecting them, mark them well and keep them growing. Then you can spray pesticide once to prevent and control pests and diseases. At this point you can begin applying more fertilizer and maintain the water supply to ensure the loofahs keep growing healthily.
2. Extracting the Seeds
Loofah seeds should be extracted only after the gourds are fully mature, so that the seeds will be fully developed and not deformed, incomplete, or underfilled. When the outer shell of the loofah is hard and gradually turns withered yellow and changes color, you can harvest the seeds. Pick the loofah, split it open, shake out the seeds, and then remove the fibrous vascular network and the pulp.
3. Treating the Seeds
Select plump, intact, large seeds, and remove the other small seeds or empty, shriveled ones. Wash them once to remove some adhering matter. Rub the seeds with alkaline water until the seed surface is clean and no longer slippery, then wipe them dry and put them in the sun to dry for one day. After removing part of their moisture content, they can be stored. Alternatively, dry them in a shaded, ventilated place. However, the sun can appropriately sterilize them, so it is best to soak them in a chlorothalonil solution for 10 minutes before drying them in the sun, to prevent bacteria and pests.
4. Storing the Seeds
After treatment, the seeds should be stored in a dry environment with low oxygen content and low temperature, because this ensures the seeds will not become moldy and spoiled and unusable, or be eaten by insects that have nowhere to forage in winter. It also prevents the seeds from suddenly sprouting on their own. Therefore, in the end, store them in a sealed glass bottle or a sealed plastic bag or porcelain jar, which preserves them well. You can also use the sand storage method, which helps maintain seed vitality, but a small number of seeds may become moldy.
The specific loofah growing process is the content described above, and in actual production you can seek better operating methods. You can also ask experienced growers or some agricultural experts to choose the most suitable method. I hope what I have said will be of some help to those who need it.
