Rose Plant and marigold plants dried out | Container gardening | Hydroponics farming in India

Hi,

I have 2 rose plants, a regular yellow rose and a tea rose plant (sorry do not know the actual name or variety) the thing is both these plants have absolutely dried out with no leaves however a few branches are still green.

I have planted the roses in the same container and added G5 (swaroop) about 10 days ago.

The marigold plant with orange red flowers when I bought it looked very healthy and had many buds and flowers but about 10 days ago this too dried out completely with no green branches.

Some more info:

I have planted them on east side window with a lot of morning sunshine, i water them every morning and I live in mumbai.

I am very new to gardening and plants so I would like to know what can I do to make the plants come alive and bloom.

Thanks,

J
