  • Fertilizer
  • Grow your finger lime tree in a 7 to 10-gallon pot so you can keep it outdoors in the warm months and move it inside during cold weather or freezes. Like all citrus trees, finger lime can be kept inside as long as it gets enough sunlight. This tropical tree is also well suite to greenhouse growing.

  • Maintain your finger lime's soil needs. Finger lime needs quick-draining soil, so keep it in a mix of equal parts sand, peat and perlite. Make sure the tree's pot is getting adequate drainage through a drainage hole at the bottom.

  • Fertilize your finger lime with a consistent diet of 3-1-1 or 12-8-4 fertilizer. Feed the tree once a month, and always follow manufacturer directions when mixing and feeding fertilizer.
