  • USDA Zones: 9 or above 9. 
  • Type of Soil: Well-Drained Soil
  • When Is Grapefruit Season: Springs or Fall. But the Spring Season Is Best.
  • Sunlight: Full Sunlight

Growing From Seeds

You can grow grapefruit from the seeds, but it is not recommended as there are high chances of failure. The grapefruit growing through seed is also not good as compared to the method of growing through saplings. 

Growing through seed also takes longer in comparison to the saplings method. 

Growing From Saplings

For planting the grapefruit using a sapling of the tree, you need to follow these steps:

  • Dig a hole that is twice the size of the root ball of the grapefruit tree. 
  • Keep the depth similar to the size of the root ball. 
  • Now remove the grapefruit from its container and look if the nursery has used a growing medium or soil for its growth. 
  • If it is a medium and not soil, then gently wash off the medium before planting it. 
  • Now plant the sapling in the hole you dug in a way that is slightly higher than the container it was in before. 
  • After this now fill the hole with soil and tamp gently around the sapling, merging its roots properly like they were in the container. 
  • Now water your grapefruit tree just after planting. But remember that you don’t uproot it with water pressure. 

What To Do If Planting Multiple Grapefruit Trees?

You need to follow the same procedure for the plantation of multiple grapefruit trees, as we told above. One thing to remember is that you should keep a gap off at least 15 to 20 feet between them. 


The mulching of the grapefruit tree is not recommended as it may lead to rotting of the roots and trunk. Grapefruits are prone to rotting. However, if you feel compelled to go for mulching, then you should keep at least a gap of 1 foot from the trunk of your grapefruit. 

How To Use Herbicides?

The grapefruit tree is a sensitive plant, and thus, it is best to remove the weeds and grass by hand. However, if you go for application of the herbicides, then follow these steps:

  • First, wrap your tree’s trunk using aluminum foil. This will protect it from chemicals. 
  • Now use a herbicide spray and apply it gently directly on the weeds and soil. 
  • When applying, you should be careful not to spray the leaves or the other parts of the grapefruit tree. 

You must know that removing the weeds and grass is essential as, like other plants, grapefruit trees also don’t like to compete with grass and weeds for growth. 

When Is The Grapefruit Season?

Like any other plant, there is a specific season for growing the grapefruit tree for the best results. 

You can grow your tree in the fall or spring; however, the spring season is more preferable and gives the best results. Plantation in the spring gives the plant more time to grow and establish before the onset of winter. These tips are specifically for the colder regions where winter can be a problem. 

However, if you live in warmer areas and winters are not harsh, you can plant it in any season. It can thrive in almost all seasons until it’s not too harsh for it. 


  • The grapefruit tree likes well-draining soil, and thus, you must be careful that it doesn’t stand in water. 
  • If you have soil that drains poorly, then you can amend it using sand. 
  • Wet and poorly draining soil for the grapefruit means short life and low production of fruits. 
  • For best results, you can go for mound plantations, where you plant them on a raised platform. This will help you in providing them with better drainage. 


  • The grapefruits need watering every 3rd to 4th day until they establish properly.
  • Once they have established themselves, cut your watering schedule short and water them once a week. 
  • One thing to remember before watering is that makes sure that the soil around it is dry. This is essential as it doesn’t like wet soil conditions. 


The grapefruit tree requires full sunlight for at least 8 to 10 hours a day for best results. Thus make sure you plant in an area where it gets enough sunlight but remember, too much heat can cause burns. 

This is common for all the varieties, including the ruby red grapefruit variety. 

Grapefruit Diet

The grapefruit-like any other plant, requires nutrients for proper growth. For this, you can follow these steps:

  • During the first 2 or 3 years of its growth, you need to fertilize it for the best results. 
  • Use a 6-6-6 type of fertilizer. 
  • After the tree starts to bear fruits, switch your fertilizer to citrus fertilizer. 
  • Provide it with fertilizers three times a year. First during the spring as it is the growing season, then in when it starts to bear fruits, third when fruits start to mature. 

If you provide the grapefruit diet or fertilizers properly to it, then the fruits can bear more than 25 pounds of harvest in the first harvest. 


The grapefruit tree is a low maintenance tree and thus doesn’t really need pruning. However, if you see the winter damage, you can do the pruning once the winter season is gone. You need to cut away the damaged and dead leaves and wood from the tree. 

Avoid excessive pruning as it will stress the tree. This is common for most of the varieties of this plant, whether it is ruby red grapefruit or any other variant. 

How To Protect a Grapefruit Tree In The Winter Season?

The protection of the grapefruit is an essential thing for the best results. Follow these steps for it:

  • When the grapefruit is young, you can go for soil banking. Near Thanksgiving, it time to treat the trunk of the tree with a copper fungicide and insecticide. Now around the trunk, build a mound of soil that goes up to the height of leaves. 
  • After the winters till the beginning of March, keep the sound and wash it off carefully. This method works well until your tree is 3 t 4 years old, but after that, it is not practical. 
  • Another method which you can try for your big plants is to cover them using a tarp or plant cover. 
  • For an added heat, you can wrap the tree in incandescent Christmas lights. 
  • In case you are growing the dwarf variety of grapefruit in containers, then simply bring it indoors. 

These are some steps that you can follow to protect your grapefruit tree from the harsh winters. 

Pests And Problems of Grapefruit Tree

The grapefruit is relatively a pest-free plant, but still, it can face some problems. These are:

  • If you see holes in the tree, then it may be due to rodents. Thus find and remove any rodent nests around or near the tree. 
  • Aphids and Asian Citrus Psyllid. These are two common insects that may harm your plant. For this, you can remove the aphids by simply jetting the plant with water. For psyllid, you need to jet it using a homemade soap insecticide. 
  • When spraying it with soap, you need to be through as it only affects insects that come in direct contact with it.
