5” tall. What can i do?
Indoor in winter outside in summer. Blooms all year.
If we knew what kind of plant it is and what your specific question is we may be able to give a better answer.
If you are looking to increase the growth rate of a 5 inch tall plant, usually soil fertility and water management is the key.
Water it, but not too much or too little. Fertilize with a natural slow release complete fertilizer on recommendation from you local garden center for the specific plant. If it's that small and in a pot, maybe you can carry it in for a face to face (or face to flower as it may be) nursery professional opinion.
