    A Sweeter Red-Fleshed Grapefruit

    The fruits of Rio Red Grapefruit trees (Citrus x paradisi ‘Rio Red’) are truly a feast for the eyes. But one taste of the sweet flesh reveals the true treasure. Although red-fleshed grapefruit varieties are bred to be sweeter than light-colored grapefruits, Rio Red Grapefruit is even sweeter and tastier than other red varieties. Each large fruit has a pinkish blush on the outside and deep-red flesh inside for an explosion of color in a healthy package!

    Superior Benefits
    Rio Red Grapefruit is not only bred specifically for its improved taste; it also brings a host of other benefits to your landscape, such as:

    Vigorous growth. The trees are well-branched and sturdy, and they don’t succumb to many of the diseases and pests that plague other citrus trees.

    Seedless fruits. Rio Red grapefruits have very few seeds. You’ll find occasional seeds, but they certainly won’t detract from the predominantly fleshy fruits.

    Heavy yields. You’ll only need one Rio Red Grapefruit tree to bear fruit, but multiple trees will magnify your harvest. Trees that are 3 years old typically bear up to 25 pounds of fruit, with yields increasing each year as the trees mature. By the tenth year, each Rio Red Grapefruit tree yields approximately 250 pounds of fruit!

    Planting and Growing Tips
    Unlike other citrus trees that can be a little fussy and hard to grow, Rio Red Grapefruit is a surprisingly easy-care and low-maintenance tree. If you take the time to choose a good planting site and properly plant it, the tree will reward you with luscious harvests year after year.

    Sun. Lots of sun means more fruit! Trees are much more productive when planted on sunny sites that receive at least 6 hours of afternoon sun.

    Water. In the first couple of weeks after planting, Rio Red Grapefruit trees need watering every few days. Thereafter, the trees need 1 inch of water weekly. Easy watering tip: Build up the soil in a ring around the tree at ground level (don’t make a deep basin). Construct the ring 3 inches high and wide, and locate it 2 feet from the trunk. On watering days, fill the ring with water. Over time, the ring will gradually sink into the ground, which indicates the tree no longer needs this watering method.

    Soil. The soil must drain well. Soggy soils lead to root rot, which can potentially kill a Rio Red Grapefruit tree. Sandy loam soils are ideal, but with good drainage trees are adaptable to many types of soil.

    Fertilizer. Fertilize according to soil-test recommendations. In the absence of a soil test, use a fertilizer that’s formulated for citrus trees, and follow all label recommendations.

    Pruning. Rio Red Grapefruit trees grow naturally without the need for pruning to maintain their shape. You’ll only need to trim broken, dead, or dying branches.

    Frost protection. During the first few years, young trees benefit from frost protection. This can be as simple as using sheets, lightweight blankets, or burlap to cover the trees when frost threatens.

    Wind protection. It’s also important to protect Rio Red Grapefruit trees from cold winter winds. Don’t plant trees on the north side of your house; southern, eastern, or southeastern locations are better choices.

    Container Culture
    If you live outside Rio Red Grapefruit’s perennial range in USDA Plant Hardiness zones 9 through 11, you can grow it in a large patio pot that you move indoors to a sunny room or heated greenhouse for the winter! Use a commercially packaged potting mix that’s formulated for citrus plants, and make sure the water drains freely from the container. When the weather warms in spring, simply move it back outside, gradually moving it to a full-sun location.
