A step by step guide to growing Grapefruit in the backyard

Grapefruit trees prefer well-draining, loamy soil and dwarf Grapefruit trees can be grown in pots. Growing a sweet Grapefruit tree can be tricky but not impossible if you know how to provide it with ideal growing conditions. Also, keep in mind that a standard Ruby Red Grapefruit tree size is about 15 to 20 feet high upon reaching maturity. While a dwarf Grapefruit tree can grow to up to about 12 feet in height when planted directly into the ground, or smaller when planted in a container, so you have to prepare the area where you will plant it before purchasing a Ruby Red To increase the sweetness of Grapefruits, plant trees in warm locations. Grapefruit keeps well on the tree after it is mature, with an increase in fruit size and sweetness over time. Keep in mind that newly planted Grapefruit trees will take at least 3 years before producing quality fruit. Any fruit set in the first or second years must be removed to direct all its energy into growth.

Grapefruit varieties for growing in the backyard of home garden

Grapefruits have a yellow-orange skin and their insides are segmented and acidic, varying in colour. The popular varieties of Grapefruits are White Grapefruit, Pink Grapefruit and Ruby Red Grapefruit and they have varying degrees of seeds and sweetness.

Cocktail – It is sweet, juicy, light orange flesh and medium-size fruit.

Duncan – It is superior flavour; the balance between sugar and acid; very juicy; and yellowish-white flesh.

Marsh or Marsh Seedless – It is good flavour very juicy; best flavour in hot summer climates; fruit more acidic in cooler regions.  

White Grapefruit – White Grapefruits are typically a pale yellowish or amber colour to white colour inside.

Pink Grapefruit – Pink Grapefruit is a hybrid of a red and white Grapefruit.

Ruby Red Grapefruit – The Ruby Red Grapefruit is among the most popular citrus varieties; also called “Ruby Red” for their bright reddish or pink interior colour.

Cocktail – These small bright green beauties are the size of a navel orange and pack a wallop of flavour.

Pomelo – The largest of all the Grapefruit varieties, you can often find these at Asian markets.

Oro Blanco – This varietal is the size of a standard Grapefruit, with yellowish-green skin and pale white flesh.

Red flesh Grapefruit also called ‘Ruby Red’- It is fine flavour; very juicy flesh is red but fades to pink; few to no seeds; large fruit; yellow rind has a reddish blush in warm climates.

Both standard and dwarf Grapefruit trees flourish in well-draining, loamy soil. Avoid planting your trees, particularly the Ruby Red Grapefruit trees, in soil that is clay laden or high in salinity as these types of soil can inhibit the growth of citrus trees.

Choose a sunny spot with well-drained soil. If the soil is clay-based, improve soil structure by adding gypsum and forking in well. In poorly drained areas, citrus can also be planted in a raised mound of free-draining soil.

Seed preparation for growing Grapefruit in the home backyard

Grapefruit seeds do not need extensive preparation, although the seeds must be sown fresh. Rinse the seeds in clean water after removing them from the fruit to get rid of the sugary residue, and then pat them dry on a paper towel. Do not let the seeds dry out completely. Seeds taken from ripe fruit perform best, so collect seeds from Grapefruits with a solid, pure gold skin with no hint of green at the ends.

Sprouting the Grapefruit seeds in the backyard

When sprouting the Grapefruit seeds, they should be kept warm and moist at all times. If the top of the soil is dry to the touch, water it immediately. Covering the flowerpot or seed tray with plastic wrap reduces the rate of evaporation from the seed-starting mix, and making it easier to keep the soil moist. Once the Grapefruit seeds germinate, in 12 to 15 days, remove the plastic wrap. Mist the soil regularly to continue to keep it moist as the seedlings develop into Grapefruit plants.

Grapefruit seed sowing and germination

Grapefruit seeds can be started at any time of year, while they perform best when started in spring as the days lengthen and the weather warms.

Step 1) Wash a small plastic pot that has drainage holes around the base. Size doesn’t matter, although smaller, 2 to 3-inch pots warm up easily. Dry the inside with a clean cloth.

Step 2) Fill the pot to within a 1/2 inch of the top with sterile, soilless potting medium, or make your own by combining equal parts milled peat moss and half perlite or medium-grain sand. Then, saturate the mix with water and let the excess drain off for 15 minutes before sowing.

Step 3) Sow three Grapefruit seeds in the pot and sow the seeds at an equal distance from one another at a depth equal to twice their length. For example, a 1/8-inch-long Grapefruit seed must be sown at a depth of 1/4 inch, while a 1/4-inch-long seed should be sown 1/2 inch deep.

Step 4) Cover the fruit seeds completely with soil to block out the light. Loosely drape a sheet of plastic wrap over the pot and move it to a warm spot where temperature levels stay between 21 and 26°C. A propagation mat works well, but the pot will stay just as warm on top of a refrigerator.

Step 5) Lift the plastic wraps and then water the seeds whenever the soil feels dry on the surface. Add water slowly to avoid dislodging the seeds. Keep the soil moist in the top 1 inch or so. Put the plastic wrap back in place after watering.

Step 6) Watch for the first Grapefruit seedlings in 2 to 3 weeks. Remove the plastic after they emerge, and move the pot to a bright, sunny spot indoors near a lightly shaded south-facing window.

Planting Grapefruit tree

First, choosing a suitable location is also important. For instance, when planting a Grapefruit tree, an area on the southernmost side of the home not only offers the most sun but provides optimal winter protection. Keep the tree at least 12 feet from buildings, walks, and driveways, etc. This will allow for adequate plant growth.

Grapefruit trees can be planted in spring or fall, depending on where you’re located and what works best for you and the region’s conditions. Keep in mind that those planted in spring should contend with the heat of summer while fall-planted trees must endure the hardships of unseasonably cold winters. Dig the planting hole both wide and deep enough to accommodate the plant roots. After placing the tree in the hole, backfill halfway with soil, and firmly pressing down to squeeze out any air bubbles. Then water the soil and allow it to settle before backfilling with the remaining soil and keep the soil level with the surrounding area or slightly mound it. Setting it any lower will lead to standing water and then cause rotting. And, be sure that the bud union remains above the soil.

Water requirement for Grapefruit trees growing in the backyard

After planting a dwarf Rio Red Grapefruit tree or a dwarf Ruby Red Grapefruit tree in a pot, deeply-water it every 3 to 4 days for the first few weeks. When watering, let the water flush through the pot, and then allow the soil to fully drain. Before watering it again, make sure that the soil is dry or you may overwater the Grapefruit tree. You can use an inexpensive moisture meter to make sure you do not overwater the tree. Keep in mind that too much water or moisture could damage the roots of the Rio Red Grapefruit tree. You then transition the deep-watering technique to once a week, except for the dry season when more water could be needed. 

Grapefruit trees require water, especially during drier months, but too much water can cause the leaves to yellow and fall from the tree. Check your watering schedule, and change it so you only water when the top several inches of soil around the Grapefruit tree has dried out. Most of the yellowing and fallen leaves from a Grapefruit tree that has been over-watered will be from the older portions of the Grapefruit tree. Too much water contributes to the development of root rot. If the plant roots are dark brown instead of tan and the outside of the root pulls away, you have root rot, which can prevent the roots from taking up water. To correct the problem, reduce the watering amount but water more frequently and ensure your Grapefruit has adequate drainage.

Growinf Grapefruit from the seed in the backyard

  • Remove the seeds from a fresh Grapefruit. Wash the seeds under running water and pat them dry with a towel. Then, fill a 4-inch pot three-fourths full with a rich potting mix that drains well.
  • Press one Grapefruit seed into the center of the pot and push the seed into the soil so it is twice as deep as the seed is long. For example, if the seed is about 1/4 inch long, plant the seed 1/2 inch deep.
  • Water the newly planted Grapefruit seed until the soil is moist but not soggy. Then, cover the pot loosely with plastic wrap to create a greenhouse effect to keep the seed warm and encourage growth.
  • Place the covered pot in a brightly lit, warm location with a consistent temperature of around 21°C. Monitor the progress of the plant, adding water as necessary to keep the soil moist and watch for the seed to sprout and leaves to form.
  • Under ideal conditions the Grapefruit seedling c flower and produce fruit in 6 to 7 years.

Nutrients requirement for growing Grapefruit in the backyard of house

Potted Grapefruit trees deplete the nutrients in the soil quickly, and there is limited room for soil and roots inside the flowerpot. Then, to replenish the essential nutrients and micronutrients necessary for the Grapefruit tree to thrive, water biweekly with a liquid fertilizer formulated for citrus trees.

Nutrient deficiencies of zinc, iron, or nitrogen can cause the plant leaves to yellow. Subtle differences in the appearance of the plant leaves will help you identify the exact cause. Normal-sized yellowing leaves with dark veins can be caused by a lack of iron. If the leaves are smaller than expected but have dark veins, the Grapefruit tree may need zinc. Nitrogen-deficient Grapefruit trees have pale yellow leaves that remain on the Grapefruit tree. Growing Grapefruit trees in alkaline or saline soil may encourage nutrient deficiencies as these types of soils to make it harder for the trees to absorb soil nutrients. Treat any micronutrient deficiency with a combination of micronutrient spray on the Grapefruit tree.

Care for Grapefruit trees growing in the backyard

  • Grapefruit tree care is essential to maintain its overall health and production. After planting, you should water every few days for the first couple of weeks. Then you can begin watering deeply once a week, except during dry periods when additional water may be needed. You can also add light fertilizer during irrigation every 4 to 6 weeks.
  • Don’t prune your Grapefruit tree unless removing old weakened or dead branches. Winter protection can be needed for areas prone to frost or freezing. Although many people prefer to simply mulch around the tree, it is advisable to leave at least a foot of space between the trunk and mulch to avoid any problems with root rot.
  • Water your Grapefruit tree slowly and deeply once every 2 weeks. Water newly-planted Grapefruit trees once every 2 to 3 days for the first three weeks, gradually decreasing the watering frequency to once every 7 to 10 days during the next 3 to 4 months.
  • Some diseases can cause yellowing in places on the plant leaves. Citrus canker can cause yellow-ringed spots on the plant leaves and fruit. The most common conditions that lead to citrus canker are warm weather and excessive moisture from rain or watering during the active growth of the Grapefruit, leaves, and branches. Rodents may cause the leaves to yellow by girdling the trunk. Protect the trunk of the tree to prevent this from happening in the future.

When and how to pick Grapefruit

We know when to pick Grapefruit, but not all of the fruit will be ripe at the same moment. This is where color is another indicator of ripeness. Grapefruit must be harvested when at least half of the peel has started to turn yellow or pink. Mature Grapefruit could still be green in color, but a better bet is to wait until the fruit turns hue. Remember, the longer the fruit stays on the Grapefruit tree, the sweeter it becomes; so be patient. When ready to pick, simply grasp the ripe fruit in your hand and gently twist it until the stem detaches from the Grapefruit tree.

Generally, harvesting takes place in the fall. Once the Grapefruits have turned yellow or gold, they’re ready for picking. The longer the fruit remains on the tree, though, the larger and sweeter it becomes. Keep in mind that newly planted Grapefruit trees will take at least 3 years before producing quality fruit. Any fruit set in the first or second years must be removed to direct all its energy into growth.
