'Grapefruit' is a plant in the Citrus genus with a scientific name of Citrus x paradisi.
Blooms appear in these approximate colours: White. When ripe, fruit appear in these approximate colours: Mellow yellow.
A type of flowering edible fruit, it mainly grows as an evergreen plant - which means it retains leaves throughout the year.
Keep in mind when planning your garden that Grapefruit is known for growing to a tree habit. This plant tends to bloom in late winter.
Grapefruit is a great plant to attract butterflies and bees to your garden.
Grapefruit is normally fairly low maintenance and is normally quite easy to grow, as long as a level of basic care is provided throughout the year. Being aware of the basic soil, sun and water preferences will result in a happier and healthier plant.

Non-bearing trees – fertilizer every two months approximately 50-100 g/tree of 14N, 14P, 12K TE. A minimum of two annual foliar sprays containing zinc, iron, copper and manganese. Foliar sprays should be applied on semi-matured, vegetative flush.
Bearing trees annual fertilizer – Nitrogen at 80-100 g/tree/per year of age, Phosphorus at 10 g/tree/per year of age, Potassium at 40-50 g/tree/per year of age during July-August or after droughting. Apply 100g/m2 Dolomite before and after the Wet. A minimum of two annual foliar sprays containing zinc, iron, copper and manganese. Foliar sprays should be applied on semi-matured, vegetative flush.
Irrigation: Water to keep the soil moist but not soggy. Use under tree sprinklers. Monitor irrigation using tensiometers to keep moisture in the root zone. The method of droughting after the Wet Season for 6-8 weeks can improve flowering.
Pruning: When trees are young the most important thing is to get a canopy quickly, so don’t over prune but rather shape the tree. In mature trees remove all dead wood, suckers and “skirt” the lower part of the tree by removing all branches and shoots below a height of 30 cm from the ground.
Grapefruit likes a position of full sun and remember to water moderately. Zone 9 to 11 are typically the USDA Hardiness Zones that are appropriate for this plant (although this can vary based on your microclimate). Ideally plant in loamy and sandy soil and try to keep the ph of your soil between the range of 6.5 and 6.5 as Grapefruit likes to be in weakly acidic soil. Keep in mind when planting that Grapefruit is thought of as half hardy, so it will require protection in frosts and low temperatures.

Put the baggie on a vent if it is winter. 60 degrees will be warm enough. From this point on, you can scarify the seeds for faster germination.
A box cutter will easily penetrate the hull so you can pull a portion off. Your nails may also suffice. Pull only one side of the seed cover off. Don’t worry if the brown coat also comes off, exposing white underneath. It’s okay as long as you don’t puncture the white seedling inside.
After scarifying and sitting in a warm place, you will have happy little sprouts to plant.
Grapefruit will grow true from seed.1Try to ensure a gap of at least 13.00 feet (4.00 metres) when sowing to prevent overcrowding your seedlings. Soil temperature should be kept higher than 60°C / 140°F to ensure good germination.
