can people please help me out on what can I do in order to grow the plants in containers. This summer, I had planted bitter gourd as well, as bottle gourd and lemongrass in different containers. These were in large grow bag containers measuring about 3 feet in height and 2 ft in breadth and length (one plant in each of the containers). I filled them with potting mix. I also made the holes at the bottom for drainage and in fact made holes in the side also. I placed them by the side of a bed where the same plants were planted in the ground.
The bitter gourd produced only a few fruits though it did flower quite a bit but none of the fruits ever grew. The bottle gourd was similar. While the plant, which was in the ground produced almost 30 KG of bottle gourd, the plant in the container produced around three KG. For the lemongrass, the one which was planted in the ground looks like a thick bush. The one planted in the container did grow, but it is a far cry from being dense.
All I could understand from reading about plants being grown in container was that the drain it should be good and therefore we made sure that the soil was properly aerated. What else can be done?
Are there any case studies or even papers anywhere on this? Most of the knowledge that I have got is by watching YouTube videos and reading about it and none of it is helping so I thought maybe getting more technical perhaps will help.
Please advise. Thank you for any inputs Edit : as required in the comments, I am appending the photographs. The first one is the image of the lemongrass planted in the ground. The second is the image of the lemongrass planted in the container. You can see how dense the lemongrass planted in the ground is as I was not even able to capture the entire plant with the camera standing at about the same distance as I was when taking the picture of the lemongrass in the container. The third picture is that of the larger container that I had used with the same results for the lemongrass as in the smaller container
