The editor answers for everyone about how to grow watermelons on the balcony. Here are the introductions concerning growing watermelons on the balcony and the methods, as follows:
1. Buy seeds first, don't use the seeds saved from last year, otherwise, you won't be able to tell what they are when they grow. Remember to buy seeds for mini watermelons.
2. Find a container and fill it with some garden soil, which should be loose.
3. Soak the seeds in water for 3-4 hours in advance to promote germination, then sprinkle the seeds evenly on the soil, cover them with a layer of soil, and spray a little water, not too much.
4. Water normally after the seedlings emerge. When they grow 3-4 true leaves, you can transplant or pot them, remember to keep the strong ones.
5. When the seedlings grow and start to produce vines, you need to do some guiding to make the melon vines grow upwards.
6. Usually water with some rice washing water or apply a little compound fertilizer, not too much.
7. Pollination is very important if you want to grow watermelons. Since there are no bees on the balcony, you need to do it manually. Pollination method: After the watermelon flowers bloom, use the male flowers that bloom on the same day to apply to the female flowers that bloom on the same day, so that the pollen of the male flowers is scattered on the stigma of the female flowers, which is auxiliary pollination.
8. After the watermelons are formed, it's best to find something to support the melons, so that the vines don't break from holding them.
9. Continue to wait for them to ripen.
