I have a small indoor garden. Things start well but after 3 months or so they start to die.

Question

I am not sure what is happening, I had three plants in the same pot. Two are cucumber and one is cantaloupe.
.The healthiest of the cucumber started to flower; I removed some of the flowers and the plant started to die. The other two in the same pot are doing ok, but now the cantaloupe is starting to wilt. I have had quite a few other plants that do very well, then they just quit growing, stall out. Some will start to have wilted leaves, or curl. The soil is not dry or wet, I water them about every 10 to 12 days as needed.
Any help would be appreciated.

Answer 1

A single cucumber will require a VERY large container indoors, as well as horticultural grade lighting. You will not be able to provide enough through the window to even keep it alive, much less getting it to fruit.

You will have to grow each of these in a container that is at least 2 gallons each. They will need about 100 watts per square foot of lighting of some sort as well.

Can you include photos of the area, the plants, containers that you intend to use, and any other useful photos? This will give me an idea of the space that you have to work with, the amount of light that they are receiving and just to see the plants. This can give me a better idea of what I can recommend to get them looking better.
