Click to see full answer. Similarly one may ask, what months do you fertilize citrus trees? When to Apply Citrus Fertilizer In general, you should be doing your citrus fertilizing about once every one to two months during active growth spring and summer and once every two to three months during the tree's dormant periods fall and winter. Also, when should I fertilize in Phoenix? The best time to fertilize these trees is during late winter or the early spring months. For best year round results fertilizing these citrus and fruit trees should be started in the month of February.

In the backyard orchard, proper pruning in addition to the application of nitrogen in the spring prior to or at bud break helps maintain this productive status. Other than nitrogen and zinc, iron and manganese may limit growth due to our alkaline soil conditions.Apply nutrients based on a soil test analysis conducted by the soil testing lab at Colorado State University or another analytical lab of your choice. The amount of nitrogen to apply can be based on how much shoot growth occurred the previous season or on a soil analysis.
Reduced fruiting wood and reduced fruit production results when the growth rate is less than what is recommended in Table 1. Each year of growth can be identified by the ring of bud scale scars remaining when the bud at the tip of the shoot grows.
Use the average length of annual growth to determine if and how much nitrogen should be applied. Stone fruit trees i. If too much nitrogen is applied it can lead to excessive leaf and tree growth over fruit production.
Apply this amount if growth the previous year was at the low end of the recommended rate. As with stone fruits, apply less nitrogen the closer the actual growth rate approximates the recommended growth rate. Maintain a record on the amount of nitrogen applied each year and the resulting growth. Such records provide a guide for the amount of nitrogen fertilizer to apply to achieve the desired results. If a soil analysis has been conducted, the recommendations in Table 2 indicate the amount of nitrogen to apply.
Note: The above information is specific to apples and pears. Add 0. Fertilizer products contain specific quantities of nutrient based on percentage by weight. This is indicated on the product label such asThe first number 15 is the percentage by weight of nitrogen, the second number is the percentage by weight of phosphorus P 2 O 5 and the third is the percentage by weight of potassium K 2 O.
For example, ammonium sulfate contains 21 percent nitrogen while blood meal contains 12 percent to 13 percent nitrogen.
The amount of the fertilizer product needed is calculated by dividing the pounds of nutrient needed by the percent of that nutrient in the product. This tells you 3.Pruning the same amount each year will result in the same amount of stimulated growth. If the tree is pruned more severely, apply less nitrogen fertilizer.
This will help avoid excessive growth. Irrigating too frequently or too much at one time, as is common with fruit trees planted in turf areas, stimulates growth and subjects fruit trees to possible root rot diseases.
Take into account excessive irrigation and correct if possible. Eliminating the grass around the base of a fruit tree and applying a thin layer of mulch is recommended. Kill the grass with a glyphosate product, horticultural vinegar or fatty acid product such as Scythe before applying mulch. It is highly recommended to plant the backyard fruit orchard away from turf where the trees can be watered and fertilized based on their needs and not that of turfgrass.
Bitter-pit and cork spot in apples Figure 8 is a direct result of the inability of the tree to move adequate calcium into the fruit. The area below the skin becomes dark and corky. These spots may appear at harvest or during cold storage.
Young vigorous trees with few fruit and trees that are over irrigated and over fertilized are more susceptible to this disorder. Calcium sprays are formulated by adding calcium chloride to water at the rate of 3 to 4 pounds per gallons or 0. Apply the first spray about mid-June, a second in mid-July, and a third in mid-August. Trees not affected by this condition will not need this treatment. Iron deficiency symptoms result in the leaves at the end of the branch being yellow or light green with a network of deep green veins.
Margin leaf burn may be evident. This deficiency often results in reduced fruit yields and poorly colored fruit with a flat taste. Apply chelated iron at the rates recommended in Table 4. To help correct this problem, avoid over irrigation and improve the organic content of the soil. Zinc deficiency symptoms are common in Colorado.Since soil applications of zinc have not proven effective, the application of a zinc spray prior to bud break in the spring is recommended.
However, applications made within three days five days for apples before or after an application of horticultural or dormant oil can cause injury and should be avoided. In this case, except for apricots, apply the zinc in the fall, after OctoberMix 1 tablespoon of zinc sulfate in a gallon of water.
Thoroughly cover the tree with the spray and apply the spray until the bark is no longer able to hold the spray and spray runs off the tree. Other than the application of nitrogen and zinc as described above, base the application of the other nutrients on the results of a soil analysis.
Foliar sprays of micronutrients can give remediation for the season if started in April-May and continued until June-July. Miracle-Gro, or a similar water soluble fertilizer can be used for this treatment. Read and follow the label directions on the fertilizer container. Nitrogen N and other nutrients, with the exception of zinc, can be broadcast over the ground and watered in, or applied in a band in the irrigation furrows prior to irrigation.
Do not apply fertilizer against the trunk as tissue damage may result. Spread the fertilizer evenly and do not dump it in a pile at the base of the tree or injury will result. If the area to be fertilized is more or less than 1, 2 feet, calculate the amount of fertilizer to apply accordingly. Foliar applications can also be used if appropriate materials are chosen. Note: The Phosphorus extraction method used may be noted on the soil test results.
If not, contact the lab to determine what method was used. Note: Sequestrene Fe is 6 percent iron. Other chelated iron products may not be effective in high pH soil. Follett, R. Larsen, H. Gaus, R.

Growing up, we had a lemon tree in our backyard in California. I loved to be able to go outside and just pick lemons whenever we needed them. As an adult, I must admit that of all the different kinds of citrus trees — lemon are my favorite. Our first home in Phoenix came with two mature citrus trees in the back garden…. We did plant one, but moved a year later and so did not get to enjoy any lemons. We have lived in our current home for over 10 years and we have no fruit trees growing in the garden I may be changing that soon.
Apply fertilizer evenly over the tree basin area. In sandy soils, fertilize six to ARIZONA – DO NOT FERTILIZE CITRUS ANY LATER THAN AUGUST!

Citrus trees that yield oranges, grapefruit, lemons, and tangerines are one great way to make a property look beautiful; and they even provide shade and snacks for homeowners who have them!
There are many varieties of citrus trees: oranges, tangerines, grapefruit, limes and lemons — any of them could be grown as outdoor trees in the right climate, and many of them will also thrive as indoor plants in pots. The right citrus fertilizer schedule will make a difference in the amount of crop. Citrus can be heavy feeders of fertilizer because it takes so much energy to produce and bear fruit, but it needs to be applied at the right time. A good citrus fertilizer NPK ratio will provide a balanced amount of each of the primary nutrients that all plants need: nitrogen, phosphorous and potassium. The California Department of Food and Agriculture says that since young trees do not have well-developed root systems, nitrogen should not be applied all at once.Instead, apply nitrogen in four to six applications from late February through August.
Southwest deserts provide excellent climates for growing many kinds of fruit. Many of the most common fruit trees originated in desert or semi-desert regions and, with a little help, will grow as well here as anywhere. Some of the best to grow are almonds, apricots, figs and pomegranates. Also grown successfully are apples, nectarines, peaches, pears, pecans, pistachios, plums and scores of lesser known fruits. Choosing the correct, desert adapted varieties is important with these fruits. Some fruit trees like peaches and nectarines can be purchased in dwarf form and are ideal for container and patio gardening.
If young trees are given a lot of nitrogen fertilizer then new growth will be pushed at the expense of flowering.
Fertilizing your citrus and palm trees is key to maintaining their fruit, yield and natural beauty. These trees can be planted year round, but do best when planted during March or April, or even during the month of October. Palm trees, on the other hand, do best when planted during the warmer months of April through September.

While many plants do well in the warm weather with adequate water, hot and dry conditions can cause stress and weaknesses in even the toughest plant.
Learn which plants thrive in your Hardiness Zone with our new interactive map! Citrus trees flourish in Southwestern areas such as Arizona, and like all plants, need nutrients from fertilizer to grow. Citrus trees are heavy feeders, so it is important to fertilize them a handful of times throughout the year for proper growth, health and fruit production. Keep a couple of important things in mind when fertilizing a citrus tree in Arizona in order to ensure maximum fruit yield and function. Fertilize citrus trees in Arizona three times a year with the same amount of fertilizer each time, in February, May and August. Do not over-fertilize, as this can make fruit less juicy, with thicker peels.
Here in the low desert of the Phoenix metro area, we should see our final winter frost in mid-February. That means it's time to fertilize some of your trees just before or as the low desert spring emerges and trees begin to grow or form leaves and blossoms. Not every tree benefits from fertilizing, but it's essential to add nutrients to the soil for several types of trees you might have in your yard. The soil can only provide so much nutrition to tree roots, and Arizona soil typically lacks the important macronutrients nitrogen and phosphorous and the micronutrient iron, although specific soil makeup varies from one region of the Valley to another.
