种植西瓜作文400字观察日记英文回答：
Today, I went to observe the growth of the watermelon I planted in my backyard. I have been taking care of it for a few weeks now, and I'm excited to see how it's coming along. As I approached the plant, I noticed that the vines have started to spread out and there are several small watermelons forming. I can see the little green fruits growing bigger each day, and it's really satisfying to watch.
I have been watering the plant regularly and making
sure it gets plenty of sunlight. I also added some
fertilizer to the soil to help the watermelon grow big and sweet. It's amazing to see how much it has grown in such a short amount of time. I can't wait to taste the delicious watermelon when it's ready to be picked.
