Sour Citrus While some ants love fruit -- oranges and apples, for instance -- many ants seem to have a distaste for highly acidic citrus with little sugar.
It's natural for all citrus trees to drop excess small fruit and young blossoms in early spring to prevent overproducing. There's no need to be too concerned about flower drop, as a citrus tree only needs 1% to 2% of the blossoms to produce a Read more
You can plant orange trees in the landscape year-round, spacing multiples 12 to 25 feet apart. Create a dam of soil around the outer edge of the planting site, piling it up several inches so it keeps water over the roots. Water the orange tree Read more
Standard-size grapefruit and orange trees can grow 18 to 22 feet tall, whereas dwarf citrus varieties only grow 8 to 12 feet tall (or smaller, if kept in containers).
Frozen Fruit Oranges should be removed from the tree before the freeze, if possible, but if oranges remain on the tree through a freezing night, the texture and juiciness of the fruit can suffer. The frozen fruits no longer will be good for eating fresh. Read more
Too much water can cause the roots of your orange tree to rot. Phytophthora fungi live as spores in the soil, and moist conditions provide an opportunity for it to thrive.
Phosphate fertilizer is important for newly planted orange trees. The tree will need less once it becomes established. Newly planted trees require 1 3/4 cup liquid phosphate fertilizer mixed into the soil. After that, orange trees require only 1 pound of phosphorus every three to Read more
Orange trees are evergreen but, unlike many limes and lemons, do not produce fruit continually throughout the year. Oranges have traditionally been harvested in winter, but new variety creation and cultivation techniques now allow for harvest almost all year.
Waterlogged soil causes citrus blooms and leaves to fall off of the tree; no blooms mean no fruit. Soil watered that frequently also is ideal for the root rot organism known as Phytophthora.
This is the reason why bees can't see the color red. They don't have a photoreceptor for it. They can, however, see reddish wavelengths, such as yellow and orange. The most likely colors to attract bees, according to scientists, are purple, violet and blue.
Nutritional benefits of oranges Oranges are known for their vitamin C content, a powerful antioxidant that helps protect cells from damage. One medium orange will provide the NRV (nutrient reference value) of vitamin C for adults. They also contain health-promoting compounds known as flavanones.
With fragrant, white flowers in the spring and sweet fruit in the winter, orange trees are a popular backyard garden addition. For an interesting effect in your garden, try growing your tree on a trellis. A tree trained to grow against a trellis or other Read more

They may be perennial in warmer climates. The plants have heart-shaped leaves and delicate, five-petaled flowers that bloom in summer in cooler regions and nearly year-round in more temperate climates. Orange varieties include the Paradise New Guinea Timor (Impatiens hawkeri) and Impact Orange (Impatiens walleriana).
Yellowing leaves in oranges may also be caused by iron deficiency resulting from a high soil pH, high phosphorus, or low iron levels. Apply foliar nitrogen, such as urea, to increase set and yield.
The orange fungus growing in your mulch is a species of slime mold known scientifically as physarum polycephalum. These slime molds are single cell organisms which feed on the bacteria produced by decomposing plant material, aiding the natural decomposition process. Slime molds appear when the Read more
Some common traits of bad oranges are a soft texture and some discoloration. The soft spot is moist and develops a mold, usually white in color at first. Bad oranges, just like bad orange juice and other fruit juices, will have a distinct sour smell Read more
Most orange trees, including Oranges Navel and Valencia, are self-fertile and do not need bees to pollinate and set fruits. Another way to pollinate a standard-size or dwarf Orange tree is by manually transferring pollen by hand. Hand-pollinating Orange Navel and other orange cultivars is Read more
Orange trees can be over-mulched or mulched to close to the trunk and major roots. GardenZeus recommends bare soil only with no plantings and no mulch for a distance of 2 to 4 times the diameter of a citrus tree's trunk, and at least several Read more
Coffee grounds change the nutrients available to soil in which the orange tree is planted, adding phosphorus, magnesium, nitrogen, copper and potassium. If your soil requires better nutrients and slightly more acidity, dig the grounds into the surrounding soil about 6 to 8 inches deep.
A thin black substance -- sooty mold -- on orange tree leaves is a sign of pest infestation. Pests with piercing and sucking mouthparts, such as aphids and whiteflies, excrete a sugary liquid, or honeydew, on citrus leaves, twigs and stems. Sooty mold -- a Read more
Orange trees need a soil pH of 6.0 to 7.5, which is slightly acidic to neutral range. Use a soil test available in garden centers to test the dirt before planting. Lime is added to soil to reduce the acidity, and sulfur is added to Read more
Orange trees are generally fondest of nitrogen fertilizers to boost growth and production, but may occasionally suffer from a lack of magnesium in their diet. When this happens, Epsom salts (MgSO4), also called magnesium sulfate, provides this essential micronutrient.
They are a good source of vitamin C, as well as several other vitamins, minerals, and antioxidants. For this reason, they may lower your risk of heart disease and kidney stones. Put simply, this bright citrus fruit is an excellent addition to a healthy diet.
Light. One of the most important things you can do to encourage orange tree growth is make sure you provide enough light for your tree. Light helps the tree produce the energy that is needed to power fruit production. In order to make sure the Read more
Citrus plants require a very similar watering regime as any other houseplant. In the winter, allow the soil to dry out between waterings, as they do not like overwatering. However, in the summer, they need to be watered more regularly, possibly once or twice a Read more
For the best growing citrus plant, the plant needs at least 5 to 6 hours a day of direct sunlight. Try placing your plant on a south-facing window sill as this seems to provide the right amount of light.
Orange trees need a warm, sunny, sheltered position outdoors in summer (mainly from early to mid-June until the end of August in most parts of Britain) and a well-lit position indoors for autumn, winter and spring – preferably a cool greenhouse or conservatory.
Orange trees need to be transplanted into rich, well-drained humus that is well tilled and loose so that the roots can easily penetrate the new soil. The prepared soil area should be at least twice the diameter and half again as deep at the untrimmed Read more
Orange trees (Citrus sinensis) thrive in temperatures of 55 to 100 degrees Fahrenheit. They go dormant in winter, when temperatures drop to 35 to 55 degrees. Freezing weather, however, damages the fruit at 26 to 30 degrees.
