What’s wrong with these two plants?
The first one is a small rose plant, the second are chrysanthemums. I keep them both on my balcony and put that screen there to avoid too much sun, as it’s very sunny here and the sun is really strong (Sicily). But they still get some direct sun at about 1:00. And they always get indirect sunlight.
The rose I repotted recently, it had almost completely withered after some bad care and it’s luckily come back to life. It had three buds but they all died before blossoming, why? And why are the leaves brown? I water it every day but with very little water, as I know it’s bad and can cause root rot. I put fertiliser about every three weeks/month.
The chrysanthemums blossomed a lot after I bought them and repotted them, but in the last month they stopped opening as well. And what’s wrong with the leaves? I follow the same rule for watering as the roses, but maybe it needs more? I notice that the compost I used absorbs water instantly, but it also dries very quickly. The day after I water it is completely dry.
