What are your temperatures now? Hibiscus flower when it warm. Maybe they need fertilizer?

Its Summer over here around 38 Degree Celsius

When did you fertilize them? Can you post a picture of them?

I did fertilize them. I got it from where I got the plants from and I also see some yellow leaves wonder why

Hibiscus need at least 1/2 day of sun to flower for me.

Guess, I will have to carry them down stairs and bring them up again (phew) :|

Why?

I keep my plants in the balcony, they dont get much sun

I have rearranged my balcony garden

After nearly three months the one of my pink hibiscus bloomed

I had to decide and resort to keep my Hibiscus plants outside downstairs. I have already lost my White Hibiscus due to lack of sun light.

You know how it feels? It is like letting go of loved ones in the unknown.

Where do you live? I would repot them into plastic pots. Plastic pots retain water 3 times longer than clay ones do.

I live in India
