It like a more humid climate
Tree came beautifully trimmed. Planted the same day and set it outside in sunny Idaho. No growth or change for two months. At the end of the two months I brought it in to the sunroom which is dramatically more humid the dry Idaho and the tree expoded with blossoms and leaves. I have pollinated the blossoms and I have loads of young fruit on the tree. I'll have to thin them but we are very excited. First year fruiting is always fun.

my ruby red grapefruit
I got this on a whim because all the reviews were favorable and reported very fast fruiting. I go mine about two months ago and it has been true to form. I was a little disappointed becase at first it "just sat." But tet alone for a week and discovered it had grown a foot and was covered with blossom buds. The flowers promptly filled my room with sweet scent when they opened. Wow!

January 1, 2013
Amazing - this tree arrived beautifully packed but did have a few leaves that didn't look that happy (I wouldn't be either in a box for a few days) . I put the tree on a little stand over a drip type saucer of water (the pot is not touching the water). If I remember correctly the tree arrived December 24, today January 15 it has quite a bit of new growth and a lot of flower buds about to bloom. Very Happy

Had the ruby red tree for less than a month, the tree arrived packed very well. The tree had several buds, I planted in a large container and provide some supplemental light while indoors for the winter. The first flowers opened yesterday and they smell wonderful! once warmer we will move it outdoors, if the flowers are any indication of how much fruit we will get, there will be a lot of grapefruits. We are happy with the trees and shipping and plan on buying several more trees, apple,avocado, and some others from FGT's

Great Potential
This was delivered and looks great. Being in zone 6 I was concerned about how to maintain this tree and keep it happy so it can grow. 3 weeks into it, it dropped a few leaves but is still full. I think it will be fine and hopefully bear fruit this year.

Zone 8 is not likely to work
I bought a ruby red grapefruit during fall of 2016 for Zone 8a in Charlotte NC, which passed recommendation for planting outside. During winter I covered tree with 2 bales of pine needles and 2 layers of white 'frost protection fabric.' The winter was mild, dipping into the upper 20's. The tree's trunk and branches died, but the roots survived and have sprouted new branches from the base of the stem that are now about 2-to-3 feet tall. If I had to do over, I would recommend putting the plant into a pot when in Zone 8.

Planting & Care



It's Easy to Plant & Care for Your Ruby Red Grapefruit


Ruby Red Grapefruit Planting Diretions

The Ruby Red grapefruit (or Citrus paradisi “ruby red”) is a citrus tree that is known for producing a yellow fruit with a seedless, red flesh interior. Also referred to as a “redblush tree”, the Ruby Red is a fast growing tree that can get to a mature height of 15-20 feet tall (if left unpruned) and a width of 8-10 feet. The tree is a tropical citrus and will thrive well if planted outdoors in zones 8-11 but can be potted and brought indoors for zones 4-11 during the colder seasons. The best time to plant a new Ruby Red is after the threat of frosts have passed and before hot summer heat sets in.

Choosing a location: Location is very important when deciding where to plant your new grapefruit tree. These trees must have a full sun location with well draining soil. Avoid planting within 25 feet from buildings, driveways and sidewalks for adequate space to grow. Amending your soil before planting is recommended and a drainage test should be done on the soil. Dig a 1 foot by 1 foot hole, fill it with water and wait one hour. If the hole has drained all the water, then the location is good. If there is water retained, then amend in some sand and perlite.

Planting directions (in ground): Try to find a spot on the southernmost area of your home for optimum sun exposure and optimal cold weather protection.

1) Make your hole twice the size of the root ball and just as deep to accommodate the root system.
2) Keeping your tree straight, begin to back fill the hole (be sure the bud union is just above the soil surface). When you have the hole half way filled, firmly press down on the soil to rid it of any air bubbles and then add water to settle the soil.
3) Back fill until the hole is level with the surrounding soil or slightly mounded. Citrus hates to be in any standing water.
4) Apply a 3-4 inch layer of organic mulch such as leaves, pine needles, hay or compost and spread to the edge of the canopy. Keep the mulch 2-3 inches back from the trunk to discourage rot, disease and insects. Water slowly and thoroughly.

*TIP* For Hot, dry areas where sunburn can be an issue, cover the trunk of the tree. You can use an equal mixture of non-enamel, flat, latex paint (interior) mixed with water or just wrap the tree.

Planting directions (potted): Avoid using any type of porous containers as soil moisture is more difficult to monitor. Try and find a nice smooth edged pot like plastic which is also more lightweight and easier to move in or outdoors during cold/hot seasons.

1) Your pot should have multiple drainage holes for water to pass through easily. Drainage is essential!
2) Your potting soil should be a good quality mix that is lightweight and has inorganic materials such as vermiculite and perlite which will assist with drainage and aeration. Avoid any potting soil with chemical wetting agents.
3) When you go to pot the tree look for the grafting union. This is where the fruit tree was grafted to the root stock slightly above the root ball. This needs to remain above the soil line. Tamp down on the soil slightly to avoid air pockets.

Watering: Be sure to water your tree regularly for its first year once every 5-7 days and more frequently during the hot season and periods of extended drought. Water deeply right at the base of the tree so the root ball stays moist. After the first year the tree’s roots will become a bit more established and you can reduce to watering once every 7-14 days. Water further out from the trunk at this point to ensure all of the roots are receiving an ample amount of moisture.

Root rot is always the biggest concern with potted citrus trees so you will have to monitor the soil moisture closely at first to get an idea for how often watering will be needed. A good way to indicate when you need to water is by using your index finger. Stick it into the pot and feel around for moisture, if there is still some present in the soil, hold off on watering. If it feels like it is drying out on the top couple inches, water just enough until you see it escaping the drainage holes and stop. The aerated potting mix should assist with the drainage.

Pruning: As with most citrus trees, suckers can form near the base of the tree and rob the primary trunk of nutrients if left unchecked. Remove these growths as they appear by pinching them off of the tree or use a sterilized pair of cutters to remove them. You can easily sterilize your tool(s) by wiping them with a household rubbing alcohol. Prune off any dead or damaged branches in the early spring after the threat of frosts has passed. DO NOT prune your tree more than absolutely necessary to avoid the spread of “gummosis.”  This can be a major health threatening issue that comes from excessive pruning of the grapefruit tree. The potted Ruby Red will not require any pruning, it should develop its natural shape on its own.

Fertilizing: During the spring and summer months, feed your Ruby Red with a tablespoon of ammonium sulfate once a month during the first full growing season. The following year use a ½ cup of the sulfate once every 4-6 weeks beginning in February and ending in August. The third year use 1 ½ cups of the sulfate in the same time frame (Feb-Aug). Water thoroughly after each feeding.

Container grown Ruby Red grapefruit trees will require a well balanced fertilizer formula specialized for growing citrus. This formula already contains all of the micronutrients that the tree will need. Feed the trees regularly, but be sure to follow the directions on the fertilizer’s packaging to ensure you don’t overdo it. The typical time frame for container grown citrus is to start in February, and provide fertilizer once every 4-6 weeks until September.

We planted our new Ruby Red tree in January 2015, when do we start fertilizing? How much fertilizer and how often?
Helen B on May 16, 2015
BEST ANSWER: At planting time, don’t fertilize your tree. Instead, wait until new growth appears. Then you should begin a feeding schedule of once a month from February through October. For excellent fruit and growth production, you’ll want to use quality organic citrus fertilizer. Look for organic fertilizers formulated perfectly for citrus trees, such as Citrus-tone from Espoma and Dr. Earth Organic 9 Fruit Tree Fertilizer. If you cannot find either of those, you can use palm fertilizer, as they have almost identical requirements.

Scatter the measured organic fertilizer on the ground at least a foot away from the trunk – thoroughly water the fertilizer. Young citrus trees have an annual increased need of fertilization because their root system is increasing over this time span. Bear in mind that if you are growing your trees in containers, they will need fertilizing more often than a tree planted in the ground.
IS the grapefruit plant self-pollenating?
mohun on Aug 18, 2014
BEST ANSWER: I believe it is. I grow this tree in New England, next to a lemon, orange and pomello tree, all in pots on the patio in summer, and indoors in winter. I don't know if it is possible that the other trees can cross pollinate it??? I must do some research to look into that. But I did pick 3 beautiful grapefruits recently. They were growing on the tree over the winter and all summer long. Now 3 more baby grapefruits are growing. Good luck!
Are these grafted or from seedling? Approx how old are there respective heights?
Fred V on Apr 2, 2015
BEST ANSWER: These trees are grafted from a mature rootstock.
Ruby Red Grapefruit tree in Phoenix AZ. I just got a potted tree that has started to flower. It is about 2ft tall now. What is needed to get it planted? Should I use plant food and/or potting soil to help it take to the ground? How deep and wide does the hole need to be?
Joe S on Mar 28, 2015
BEST ANSWER: Start your planting process by digging a hole 3 feet wide in your yard. Save all soil and get rid of the grass and its roots on the top layer. Dig your hole twice as wide as the root ball. Loosen the soil beneath where your tree will sit, which will help your roots grow easier.
There isn’t any need to add compost to the existing soil. It will not improve drainage because your tree’s roots will grow deeply into the ground
During the first few months your tree is in the ground, it needs deep root watering.
No matter what kind of shrubs, trees or plants are in your landscaping – never put down mulch that exceeds 3 inches deep. Mulching around your new citrus tree is not a good idea, since it can sometimes cause fungus problems. If you simply must have that aesthetic appeal, keep all mulch two feet away from the trunk.
At planting time, don’t fertilize citrus trees. Instead, wait until new growth appears. Then you should begin a feeding schedule of once a month from February through October. For excellent fruit and growth production, you’ll want to use quality organic citrus fertilizer. Look for organic fertilizers formulated perfectly for citrus trees, such as Citrus-tone from Espoma and Dr. Earth Organic 9 Fruit Tree Fertilizer.

Have any of these trees ever come with pests or diseases?
Lindzey on Jul 6, 2016
BEST ANSWER: My tree seems healthy although it took nearly 3 months after planting before any new growth appeared! Also didn't see any pests on tree when it arrived! We will see how it grows during next springs growth cycle!
My baby red ruby lost its leaves during hurricane winds. I don't yet see signs if new leaves but the stalk is a healthy green. Will the tree survive or do I need to replace it?
Catherine W on Nov 22, 2016
BEST ANSWER: If the stalk is still green, then it's still alive. Give it a boost with some fertilizer and make sure it's watered well. I once had a lemon tree lose all of it's leaves and now it's double the size it was then.
I thought grapefruits were supposed to be sour. Are they actually sweet?
Lindzey on Jun 20, 2016
BEST ANSWER: I depends on the type or name of grapefruit and Ruby Red is one of the sweetest. The old fashion yellow grapefruit can be plain bitter.
SOIL FOR POTTED CITRUS ?
SUE M on Mar 9, 2016
BEST ANSWER: As with any other plant, the level of pH in the soil will present you with problems if it is too low or too high. For citrus trees, you need 6-8 pH for them to grow well. Citrus also is not tolerant of high soil salinity, which can be present near saltwater shores. Discovering the pH is easily accomplished with a soil tester purchased from local stores.
I live in Indianapolis which is Zone 6. I have my grapefruit tree potted outside right now and it is doing well with lots of new growth. At what temperature should I bring it inside and do I need to buy growing lights for it? If so, how long do I leave the lights on for? How often should i fertilize it?
RachB1122 on Sep 26, 2016
BEST ANSWER: Hi! I live in zone 7A/B and I leave my citrus trees out until it gets close to freezing - usually the low 40s - at which point I bring them in. I don't use grow lights - but I do have a sunroom with southern facing windows where they get plenty of light. As for fertilizing, there are several kinds of fertilizer you can use, but the important part to remember is the ratio - 3-1-1 - of whatever you use. I have used fish emulsion, citrus tree stakes and I'm about to try a new one called Dyna Gro Foliage Pro that I read about on a citrus tree blog. Some people advocate fertilizing just during growing, some say year round. Go out on the web and do some research on potted citrus trees - there's a lot out there!
Good luck!
I am in Zone 8. If planted in ground will it tolerate winter months? Would it need to be covered when temps below 32F? Thanks
Laura B on May 14, 2015
BEST ANSWER: I too live in zone 8, but last winter we had temperatures of 12 degrees Fahrenheit. I would not plant my ruby red grapefruit in the ground because those temperatures would kill it. An occasional 32 would not. My ruby red grows in a 14" nursery pot set inside a decorative ceramic pot. It come inside from Nov-Feb and lives under lights. I get a nice crop of grapefruit each winter.
can you ship to south Carolina and does the ruby red self pollinate or do I need to buy two?
ed a on Mar 24, 2015
BEST ANSWER: We can ship to SC. All citrus are self fertile, however, they work better and will be more prolific in pairs.
Do you ship these plants to Corpus Christi Texas?
A shopper on Jul 15, 2014
BEST ANSWER: Unfortunately Texas has agricultural laws put i place that prevent us from legally shipping the Red Ruby Grapefruit Tree there.

JAMES H on Jul 15, 2014
BEST ANSWER: Your Grapefruits are ready when their skin changes from green to an orange color is a splash of pink in the skin. Grapefruits can take upwards of 8 months to mature.
