1. Use a larger flower plate to load the soil in the field (preferably vegetable garden soil), the soil should be loose, and if possible, put some rotten organic fertilizer.
2. Buy seeds for small watermelons (such as Black Beauty, Huang Xiaoyu, etc.), if you use the seeds left by eating watermelons, the melons that grow may not be the original, because the current watermelons are hybrids. Large watermelons are hard to grow as they should on the balcony.
3. Soak the seeds in water for 3-4 hours, then sow them into the watered soil and cover them with dry soil (do not water them immediately after covering the soil, otherwise it will be difficult for the soil to harden and the seedlings will come out).
4. After the seedlings are unearthed, water them according to normal management, and the water should not be too much to prevent root rot.
5. When the melon seedlings grow, pull them up with a bamboo pole or rope, and let the tendrils coil on the bamboo pole or rope, so that the melon seedlings can grow upward.
6. Fertilization: It is better to use commercially available compound fertilizer, and you can also pour some rice washing water at ordinary times.
7. Pollination: There are two kinds of watermelon flowers: female flowers and male flowers. The one with the melon below is the female flower.
After the watermelon blooms, the male flowers that bloom on the same day are smeared on the female flowers that bloom that day, and the pollen of the male flowers is scattered on the stigma of the female flowers, which is auxiliary pollination. This is very important. If you grow melons on the balcony, you can't grow melons without pollination.
8. When the watermelon begins to grow, it should be hung with a net pocket, otherwise the melon will break off when the vine grows up.
9. When the melon is fully grown and the patterns on the skin begin to become clear, it can be harvested.
Ventilation, sunlight, and nutrients, watering, and whatever, it's hard to grow.
Looking at the picture, this watermelon seedling grows relatively vigorously, and it belongs to the running vine. That is to say, the first seventh leaf of the melon should be sharpened and topped. If you don't pluck the top, the nutrients can't give the nutrients to the melon, and the nutrients are used for growth, and the melon will fall off if you don't get enough nutrients.
1. Container selection: watermelon has a well-developed root system, and in order to meet the growth of the root system, it needs to have enough nutrients, and the basic source of nutrients is the substrate, which requires a large enough container. Generally, the diameter is about 30cm, and the height is about 50cm; In addition, in order to permeate water, the bottom of the container needs a small hole to run water; >>>More
