How to pot a Meyer lemon tree for indoor growth

- Create a potting mixture of 1/3 peat moss, 1/3 potting soil, and 1/3 perlite that will fill the pot
- Slide the tree from its container, cut away dry roots, fluff if matted/encircled
- Add tree to center of pot and add your potting mixture with the crown of the roots just above the soil line
- Slowly add water while pulling the tree up slightly to remove any air pockets

- Add water to the tray, filling it just below the top of the rocks to allow your tree to sit on the rocks but not IN water
- Place the pot with tree on top of the rocks
Maintenance schedule for a lemon tree
- Water as noted above
- Weekly: Turn your tree a quarter turn to ensure the tree is getting even light
- Every 2 weeks: Spray down your foliage
- Every 2 years: Repot your tree after pruning the roots to avoid the tree getting root bound
- Anytime: Prune your citrus tree to control its shape and size
Moving your citrus tree indoors to outdoor & vice versa
- Best time to move your citrus or lemon tree is when the temperatures are close to the same indoors and outdoors
- When switching, keep the tree in the shade for 2 weeks
