I have few jasmine plants which were healthy with big leaves and big blooms all these years but lately the plants are not growing and the leaves are very small and so are the blooms.I am using the same fertilizer miracle grow.please advice.
How long have they been in the same pot? Are there more roots than soil in the pots? It could be time for a repot. Also, jasmines don't need too much fertilizing in good, fresh potting mix, so over time salts may have built up in the bottom of the pot and in the mix. Those are the two main things I can think of, hope they help!
