Air layers work best with a stem thicker than a finger -- maybe thumb size. But thinner stems can be layered if you're very careful not to break them. It's easiest to work when the plant is actively putting out new growth, since the bark will "slip," meaning it will peel cleanly away from the wood. Cut a ring around the stem, cutting through the bark to the wood. Don't go deeply into the wood. You can use a knife or the blade of a pruning clipper.

The state is working with the USDA and UF/IFAS to determine new management strategies for citrus diseases. Recommendations for dealing with trees suspected of having citrus canker will be available soon. For now, you should not move any citrus plant material or fruit from your property and avoid coming into contact with the suspect plant to prevent spread of the disease. Do not mail or bring samples of suspected citrus canker or greening to extension offices. See similar questions...

Oranges and grapefruit are highly susceptible to foot rot disease, caused by Phytophthora citropthora and P. nicotiana. Some rootstocks offer considerable resistance to that disease. So on infested land, it's important to use such a stock. Rootstock variety has some effect on the strength of flavor of the fruit, the sweetness, total yield of the tree, and cold-hardiness of the tree. Some citrus scion varieties are difficult to root from cuttings. See similar questions...

A:The ideal pH for a citrus tree is 6.0 to 6.5, if it's on citrus roots, or 5.5 to 6.0, if budded/grafted to Poncirus roots or one of the Poncirus hybrids (citrumelo, citrange, etc.) Ideally, you should have your soil tested. A local extension office may do it for you, or even a local college or high school with a chemistry dept. Or you can buy fairly cheap pH meters or even cheaper pH testing paper (not very accurate, but perhaps close enough). See similar questions...

Potted citrus trees can be planted almost anytime of the year. Fall and Spring are two of the better times. Since newly planted citrus trees are not as cold hardy as more mature ones, Fall planting should be done at least two (2) months before freezing temperatures can be expected.

Please do not mail or bring in samples to your county extension office. Instead, please ask them to send an agent out to examine your tree. See similar questions...

Sooty Mold - Appears as a black, sooty growth on the upper side of leaves. Is harmless, but indicates that an insect was or is present (usually aphids, whiteflies or scales). Whiteflies. As these piercing-sucking insects feed on the undersides of the leaves, they secrete a sticky, clear fluid that drops onto the leaves below. Sooty mold grows upon this secretion. Sooty Mold Water or Varietal Problem. The problem of splitting fruits usually occurs in the early fall. See similar questions...

Chewing insect - Usually either a grasshopper or caterpillar. Damage is usually contained to a small proportion of leaves and should be ignored. The caterpillar is called an Orange Dog, and is the larval stage of the beautiful Giant Swallowtail butterfly. See similar questions...

A quad tree is an optimal method of storing information by creating subdivisions that contain small local quads. A quad tree offers the benefit of speed in rendering time. Also, search algorithms perform better. Yes, J/CarnacPro has full support for printing. We have also included a built-in editorsfor selecting paper size, orientation, fit mode and so on. There is also an option for print preview. See similar questions...

Citrus can be replanted, but must be purchased from certified nurseries that are registered with the state. Decontamination requirements have been lifted for lawn maintenance companies operating in canker quarantine areas. However, the Department encourages good sanitation practices to protect plants from harmful pests and diseases. Citrus material (trees, fruit, rootstock, leaves, potted citrus plants, etc.) should not be moved from the state without a limited permit from the USDA. See similar questions...

Spring is an ideal time to plant new citrus trees. Garden centers have a good supply to pick from, and the trees are ready to begin root and shoot growth. Make sure you give the new tree a sunny site and space the trees at least 12 to 15 feet apart. If you miss the spring planting season, don't worry. Container-grown trees are available year-round. They can be added to the landscape anytime. See similar questions...

Sometimes it is nice to place layers in groups. It makes them easier to organise when you have lots of them. It also means you can easily apply the same effect to lots of layers, without directly affecting those layers. Long story short, it makes life easier. This will be much easier to program once GEGL has been integrated into GIMP. See similar questions...

A:10 years may be long enough, but 4 feet tall from seed is the problem. Citrus trees, like most plants, don't measure their maturity in years, as do humans; rather, they measure it in number of nodes (points where the leaves are attached to the stem) from the original seed. So in a grapefruit tree, to get enough nodes along the stem, you usually need a tree 15-20 feet tall. If you keep pruning it to keep it indoors, it will never get there. Say you have an 8' tree at node 247. See similar questions...

Citrus are usually fertilized three times a year - Valentine's Day, Memorial Day and Labor Day. newly planted trees do not need fertilizer the first 1-2 years. Use Ammonium Sulfate, Ammonium Phosphate or Citrus Food fertilizer. The amount of fertilizer need per year depends on the age, the size, and the type of tree. For example, a medium-sized adult tree 5-6 years after planting needs 6.2 pounds of Ammonium Sulfate per year (split into three applications). See similar questions...

Thrice is nice. That's the recommendation on a bag of citrus fertilizer from Arizona's Best. And it makes sense if you think about it. First feeding comes near the end of winter which means February while the tree is somewhat dormant possibly looking a little under the weather because of a number of unexpected freezing nights so the leaves look a bit dried and discolored.

Start with what you like. If you like oranges pick a naval, blood, or Valencia. If you like grapefruit pick the white Marsh or a pink Ruby. What you really need to consider is where your citrus is going to be grown. Some are more susceptible to frost damage than others. And although there is always talk about covering citrus trees to get them through the cold nights of winter it's a lot of work. See similar questions...

Yes. However, you must purchase certified citrus plants from nurseries that are registered with the state and because of devastating diseases such as citrus canker and citrus greening, we strongly recommend that residents find alternatives to planting citrus – there are many wonderful fruit trees that can be grown in your area.

It’s not necessary to refrigerate citrus. However, it does make the fruit last longer. If you like your citrus juicier, store your citrus at room temperature. For more information on citrus storage, check out our Tropicana® Premium Fresh citrus? section. See similar questions...

Yes. Once you’re ready to use/eat your fresh citrus—but before peeling—wash the citrus in clean drinking water. You should not use soap or bleach, since the citrus may soak up the detergent or bleach, which is unhealthy to consume. See similar questions...
