The Victoria lime has gained popularity among home gardeners in recent years. It is a tropical plant, so you must provide protection from frost and temperatures that dip below 30 degrees F during winter. Plant your Victoria lime in a large container to protect it from the cold. Leave the tree outdoors in the warm season, and move it indoors during winter.
Remove your Victoria lime tree from its nursery pot, taking care not to disturb the roots more than necessary. If the tree has become rootbound, gently loosen the roots and free them from the soil.
Spread a 1-inch layer of pebbles or gravel in the bottom of your planting container to provide drainage. Fill your container about 1/3 full with potting soil, depending on the size of your tree's root system. Citrus trees prefer a slightly-acidic environment, so choose a potting soil that is designed for acid-loving plants.
Set your Victoria lime tree into the container, and add or remove soil, as necessary. Plant the tree so the roots are covered well in potting soil, but not so deep that part of the trunk is buried. Fill the pot with soil to within ½ inch of the top.
Water your Victoria lime tree well. Allow the soil to dry slightly before you water it again.
Set your young tree in a sunny location outdoors from late spring until just before your first fall frost. Then move it indoors---next to a sunny window is ideal, but you can hang a fluorescent light above your tree to ensure that it receives the light it needs.
