If you do opt for slow release fertilizer, apply 2 to 3 times a year.

Slow plant growth or small leaves means it either is not getting enough light or plant food. So, check both and eliminate one before trying to fix the problem.

Often, it is easier to adjust light exposure. So, start with that.

If this should happen, check if your fertilizer has the too components. If not, get a product that has them.

  • if you don’t want the plant to grow any bigger, clear out a good part of the soil in the root ball and use the same container with fresh potting soil. Alternatively, if the roots are getting too big for the pot, prune the roots. By keeping the plant in the same container, you can maintain its size for the rest of its life.
  • Water the soil thoroughly.
  • Place the plant in bright, indirect light.

Don’t worry if the plant’s growth stalls for the next 2 to 4 weeks. This is normal as it recovers from the shock of being transplanted. It will likewise adjust to its new home during that time. After that, it will start growing again.
