How to Plant Grapefruit Seed
Fill a 4-inch pot three-fourths full with a rich potting mix that drains well.
Place the covered pot in a brightly lit, warm location with a consistent temperature of around 70 degrees Fahrenheit. Monitor the progress of the plant, adding water as necessary to keep the soil moist. Watch for the seed to sprout and leaves to form.
A south-facing window covered with sheer curtains provides sufficient light without exposing the seedling to direct sunlight, which may burn the plant.
Under ideal conditions the grapefruit seedling may flower and produce fruit in six to seven years.
Water the newly planted seed until the soil is moist but not soggy. Cover the pot loosely with plastic wrap to create a greenhouse effect to keep the seed warm and encourage growth.
Remove the seeds from a fresh grapefruit. Wash the seeds under running water and pat them dry with a towel.
Transplant the seedling to larger pots, such as 6-, 8- and 12-inch containers, as it grows so the roots will have plenty of room.
The grapefruit (Citrus paradisi) has come a long way. From its first recorded history in the West Indies during the mid 1700s to propagation in Texas’ Lower Rio Grande Valley during the early 1900s, the grapefruit has become a fruit that can stand alone or be used as an ingredient in the kitchen. Grapefruit can be grown at home from seeds and planted outdoors in U.S. Department of Agriculture plant hardiness zones 9 through 11. Although fruit production can be more limited than that of commercially grown trees, growing a grapefruit tree from seed should produce fruit.
You can grow your own grapefruit tree from seed harvested from your breakfast fruit. Plant the seed and keep it warm so it germinates indoors.
If you plant a seed from a grapefruit you buy at the supermarket, chances are the seed is from fruit that was produced by hybrid plants. On the one hand, this means that your tree could turn out to be sterile and never produce a single piece of fruit. On the other hand, you may get fruit, but if you do, it is unlikely to exhibit the same size and flavor characteristics as the original fruit you took the seed from. You going to have to be very patient, because it can take anywhere from 7-9 years before a grapefruit tree is mature enough to produce its first fruit. In any event, you will have a lovely tree to show for your efforts.
For some cold weather greenery that will brighten the house and last all winter, try filling a flat pan with rich dirt and thickly planting the container in grapefruit seeds buried one half inch deep. Keep the earth well-watered. The seeds will be slow to sprout but will be worth waiting for.
Once the seed germinates and the seedling starts to grow, wait until it develops it first true set of leaves (usually the second set of leaves that appear) before transplanting it to a bigger pot. The pot does not need to be too big to start with, just make sure the soil mixture you use provides plenty of drainage.
I have a grapefruit that was started from seed, I do not know the variety. It is about 18 inches in height now and pretty healthy. The leaves are like a double leaf, in that there is a smaller section near the stem then a larger leaf beyond that. Currently it is in a 4-6 inch pot indoors, but it is exceeding it’s home now. I can’t just let it die so I would like to know how to care for it and help it live.

Wrap seeds in a small amount of moist peat moss or a damp paper towel and tuck them into a sandwich bag. Place the bag in the refrigerator for about 3-4 weeks. Then plant the seeds in a small pot. Otherwise, just bypass the fridge idea, plant them directly in the pot, and see what happens. Either way, you are bound to get something to sprout eventually.
