How are the heights measured?
All tree, and nothin' but the tree! We measure from the top of the soil to the top of the tree; the height of the container or the root system is never included in our measurements.
What is a gallon container?
Nursery containers come in a variety of different sizes, and old-school nursery slang has stuck. While the industry-standard terminology is to call the sizes "Gallon Containers", that doesn't exactly translate to the traditional liquid "gallon" size we think of. You'll find we carry young 1-gallons, up to more mature 7-gallons ranging anywhere from 6 inches to 6ft.
How does the delivery process work?
All of our orders ship via FedEx Ground! Once your order is placed online, our magic elves get right to work picking, staging, boxing and shipping your trees. Orders typically ship out within 2 business days. You will receive email notifications along the way on the progress of your order, as well as tracking information to track your plants all the way to their new home!
Why are some states excluded from shipping?
The short & sweet answer is: "United States Department of Agriculture Restrictions." Every state has their own unique USDA restrictions on which plants they allow to come into their state. While we wish we could serve everyone, it's for the safety of native species and helps prevent the spread of invasive disease & pests. We've gotta protect good ole' Mother Nature, after all.
The Rio Red Grapefruit is an improved form of older red-fleshed grapefruits, and it is more cold-resistant and faster growing. When rip it has pale-yellow skin with an attractive red flush. Cut it open and it if full of sweet, red flesh with very few seeds. Red-fleshed grapefruits are much sweeter than white-fleshed ones. The fruit stays on the tree, and the longer you leave it the sweeter it gets, so you don’t have to worry about storage. Just step outside and pick your morning grapefruit straight from the tree. It grows into a large tree up to 20 feet tall in time, and needs no pruning or special attention to quickly begin to bear large crops of fruit. One tree will produce 25 pounds of fruit in a few years, and mature trees can produce more than 200 pounds of fruit. It will grow outdoors in zone 9 or warmer areas, and in colder places it can be grown in a large pot for many years. Bring it inside when the temperatures are below 50 degrees.
- Delicious red-fleshed grapefruits
- Easy tree to grow, requiring little care
- Fragrant white blossoms
- Grow in a pot with some winter protection

Choose a sunny spot to plant the Rio Red Grapefruit. It should be planted outdoors in well-drained soil, but the exact soil-type is not important. It needs no fancy pruning, and it has no serious pests or diseases to worry about. Just plant it and start picking. Because this is a faster-growing variety than older types, you won’t have to wait long before you have plenty of fruit to eat fresh, or turn into delicious preserves. Plants in pots will stay smaller, but they will still carry full-sized fruit.
- Plant Hardiness Zones 9-11
- Mature Width 6-15
- Mature Height 10-20

Grapefruit are a popular way to start the day, but increasingly the ‘boring’ white-fleshed varieties are giving way to the sweeter, tastier and more attractive red-fleshed ones. If you love grapefruit and want to have your own supply of garden-fresh, tree-ripened fruit that have only been treated with what you chose to treat them with, then planting your own tree is a great decision.
Since you will have that tree for a long time, it makes a lot of sense to plant a red-fleshed variety, and the Rio Red Grapefruit is a newer variety that is an improvement over older types. It is an easy plant to grow and will soon develop into a beautiful tree that will be decorated with big, juicy grapefruits starting in fall and staying on the tree until the following spring. Leaving them on the tree is the best way to store grapefruit and nothing could be more convenient.
Growing Rio Red Grapefruit Trees
The Rio Red Grapefruit is an evergreen tree that can grow to 20 feet or more in time. The leaves are glossy, a deep, rich green in color and around 6 inches long. The flowers are white and scented and trees bloom usually in spring. Fruits begin to develop shortly after flowering ends, and they grow larger the longer they are left on the tree.
Knowing When Your Crop is Ripe
The first fruit should be ready to eat by mid-October while the skin is still a little green. As the green color is lost from the skin the fruit becomes sweeter. Unlike some other citrus fruits, grapefruits can be left on the tree until May of the following year. The fruit remains good and even becomes sweeter as you leave it on the tree. Grapefruit trees are heavy croppers. Even a young tree can produce 25 pounds of fruit and a mature tree can produce 250 pounds of fruit every year. One tree will give a whole family plenty of grapefruit for much of the year.
Hardiness and Climate
The Rio Pink Grapefruit tree will grow in zone 9 or warmer. It is more cold-resistant than the much older Ruby Red variety, so it can be grown more successfully out of doors even in the coldest parts of zone 9. Plant it in a sunny, sheltered place in any soil that is well-drained. Any pests and diseases that could develop are not ‘life-threatening’ and at worst will just cause some blemishes on the skin. It is easy to have healthy, chemical-free grapefruits right from your garden. Grapefruit trees need no pruning, so that another chore that is not needed for this easy fruit.
Growing in a Pot
The Rio Red Grapefruit can also be grown in a pot. Choose a large pot and add 20% coarse sand to regular potting soil, or use a cactus soil or special citrus soil. Let the soil dry a little between each watering. Always water thoroughly until water drains from the pot and do not leave your tree standing in a saucer of water. Fertilize regularly with a citrus fertilizer during the growing season. Place the pot in a warm, sunny spot.
When night temperatures start to fall to 500F bring your tree into a bright, cool place for the winter. Return it to the outdoors when the night temperatures return to 500F, but for the first two weeks bring your tree inside at night until it adjusts to the lower temperatures outdoors.
History and Origins of the Rio Red Grapefruit
Grapefruit trees have a complex history. They are the result of a cross between the orange and a very unusual citrus fruit called the Pomelo. These two trees were growing together in Jamaica and either by chance or intentionally, they cross-pollinated to produce the grapefruit, Citrus x paradisi. There were trees being grown in Barbados by 1750. Trees were brought to Florida in 1823, by Odet Philippe, the first permanent settler in the Tampa Bay area. In 1906 a pink grapefruit was discovered growing and this was taken to Texas, where in 1926 a red grapefruit called ‘Ruby Red’ was discovered.
Plants are not always stable in their features, and sometimes change into something else. Around 1980 an unusual fruit appeared on a Ruby Red tree in a citrus grove belonging to C. Henderson, outside Houston, Texas. Seeds from that fruit were collected by Dr. C. J. Hearn, a scientist with the US Department of Agriculture in Florida. He grew those seeds and developed the ‘Rio’ Grapefruit, releasing it as a new variety in 1987.
