Growing Water Spinach (Kangkong) and Chinese Kale (Kailan) from seeds use pretty much the same method as growing tomatoes. I actually planted my kangkong and kailan the same time I planted my okra seeds, eggplants seeds, pepper seeds and tomato seeds.

By the way, I’m actually on the 26th day of my very own self-imposed 30-day blog post challenge which also propelled me to restart doing other things I love and one of them is planting vegetables (obviously!)
First of all, let me tell you that unlike how I grew tomato, eggplant, okra, and pepper seeds, I didn’t study at all how to plant water spinach (kangkong) and Chinese kale (kailan) seeds. I bought several different seeds and one day I just thought to plant two more kinds and see if they will grow. After almost a month, I can say that my water spinanch and Chinese kale vegetable seeds have grown so much since then. I’ve even re-potted them which I will discuss on a separate post. For now, let me tell you how I managed to grow Kangkong and Kailan vegetables from seeds.
