Grapefruits can survive indoors and outdoors. Rather than buying a grapefruit, save money by harvesting grapefruit seeds that you bought in store or even better on the market. Grapefruit seeds or seeds germinate easily when sprouting begins indoors and then trees produce delicious fruit in as little as a year.
Discover in 12 steps how to grow a grapefruit from a seed:
1- Choose the variety of grapefruit that you want to grow then open the grapefruit with a sharp knife.
2- Remove the grapefruit seeds with your fingers to avoid damaging them. Choose the larger seeds and set them aside.
3- Wash the seeds under hot water. Place them on a layer of three wet paper towels. Fold the napkin in half. Continue folding the paper towels to cover the seeds with a thick layer.
4- Keep the paper towels moist. Place them in a warm place where they will not dry too quickly. Transplant the seeds once they start to germinate and leaves and roots appear.
5- Fill cardboard cup with soil. Plant a sprouted seed in the cup at least 2 cm into the soil.
6- The soil water must remain moist. Place the cup in a warm place that maintains a temperature of between 20 and 30 degrees Celsius. Let the grapefruit seed continue to sprout. It can last from a week to a month. Keep the soil moist and drill two holes in the bottom of the cup to help drain the water.
7- Transplant the grapefruit once it becomes too big for the cup. You will need a container twice its size. Keep it in a warm and sunny place.
8- Move the outer shaft. Once the tree has reached 60 cm to 1 m in height, plant the grapefruit outside, near a wall and facing south where heat and sunshine will be present.
9- Dig a hole at least 1 m in diameter with a shovel. The hole should be wider than the root ball, but at the same depth. Create a ring of water around the tree wider than the planting hole.
10- Water the tree every seven to ten days deep enough. Do not water the tree when it is raining and avoid excessive watering when the weather cools.
11- Add 5 cm of mulch around the tree to help retain the water.
12- Fertilize grapefruit every four to six weeks during the growing season between March and August.
