Grapefruits are citrus fruits that pack a nutritional punch. They contain plenty of vitamin C, vitamin A, potassium, and lycopene, without the high sugar content that sweeter citrus fruits contain. Grapefruits are often costly at markets and green grocers. Home gardeners save money on produce by growing their own at home. Most commercially available citrus trees are packed in flimsy plastic pots, and need to be transplanted at home.
Dig a hole in the ground 2 inches deeper and 3 inches wider than the pot it is in. Make the bottom of the hole cupped, rather than completely flat.
Put enough loose dirt back into the hole, so that the top of the root ball will sit 2 inches below the surface of the soil. This is necessary to give the root system soft, broken soil to sit on. If you don't break up the soil, the roots will have a difficult time breaking through the hard soil.
Turn the grapefruit tree on its side, and roll the container back and forth on the ground. This motion helps break up the packed soil and loosen the root ball. Pull the tree from the container, holding it by its trunk.
Examine the root system. Cut off any soft, brown, slimy roots you see. These are diseased, and will spread to the rest of the roots if they are not removed.
Hold the grapefruit tree's trunk and carefully lower it into the hole. Have a helper reach into the hole and fan out the roots.
Fill in the empty spaces with soil. Water the tree immediately, to enable the root system to work out any trapped air pockets. Thereafter, keep the ground around the tree moist. Citrus trees need a lot of moisture to develop properly.
