Beside this, how big do lemon trees grow in pots?
When planted in the ground, they can grow up to 8 to 10 feet tall and up to 12 feet wide. When grown in garden pots, your plant will be smaller and grow accordingly with the size of the pot.
Considering this, how do you transplant a potted lemon tree?
Set the tree atop the soil in the new pot, adjusting the depth of the soil so the root ball sits a couple inches beneath the rim of the container. Fill in around the roots with more soil until the tree is potted at the same depth it was in its old pot. Water the tree thoroughly to allow the soil to settle.
The best soil pH for growing lemon trees and other citrus is 6.5, according to University of California Riverside Research Facility. If your soil has a higher pH, use mulches that acidify the soil, like pine needles or coffee grounds. Regularly test your soil's pH to avoid making it too acidic.
