It’s that time of the year again folks if you have trees especially citrus ones that you want to have full of fruit year around got to make sure to fertilize at the right time. I have a lemon tree and grapefruit so this is something I definitely keep up on but I do have to keep my dogs away so they don’t eat it. If you have doggies or a tree in the walkway of other doggies always make sure to use organic pet friendly fertilizer in the event they happen to get into it! http://www.gardeningknowhow.com did this great article help for anyone who needs it:

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). As the tree gets older, you can skip dormant season fertilizing and increase the amount of time between active growth fertilizing to once every two to three months. To find the best citrus fertilizing time frames for your tree, judge based on the tree’s physical appearance and growth. A tree that looks lush and dark green and is holding onto fruit does not need to be fertilized as often. Fertilizing too much when the tree has a healthy appearance may actually cause it to produce inferior fruit. Citrus trees are most nutrient-hungry from the time they bloom until they have firmly set fruit, so make sure you apply citrus fertilizer when the tree is in bloom regardless of health so that it has enough nutrients to properly produce fruit.

How to Fertilize a Citrus Fruit Tree

Citrus tree fertilizing is either done through the leaves or through the ground. Following the directions on your chosen fertilizer, which will be to either spray the fertilizer onto the leaves of your citrus tree or spread it out around the base of the tree as far as the canopy reaches. Do not place fertilizer near the trunk of the tree.

What Kind of Citrus Fertilizer Does My Tree Need?

All citrus trees will benefit from a slightly nitrogen rich or balanced NPK fertilizer that also has some micro-nutrients in it like:

magnesium

manganese

iron

copper

zinc

boron

Citrus trees also like to have somewhat acidic soil, so an acidic fertilizer can also be beneficial in citrus tree fertilizing, though not required. The easiest citrus fertilizer to use is the kind made specifically for citrus trees.
