We purchased our Tarocco Blood Orange Tree at a 16" size (about 5 year-old) almost a year ago, February 15th 2016. Over that years time, we have been very cautious to follow all the instructions of planting, watering, fertilizing (only once in fall) that we received from Greenfield Citrus Nursery. We planted it directly into the native soil without any amendments. This was before we had clues that our soil had been treated with chemical herbicides that has been evident in stunted and deformed growth all over the yard.
Although our citrus tree has grown new leaves over the past year, the overall size (height, width and trunk diameter) has not changed much and I am seeing mostly deformed or damaged foliage on the tree which has me concerned. I am hopeful that springtime will bring some healthy new growth for our tree and this upcoming year will be productive. I also hope to seek guidance from an expert and show them the images below.
Here are some detailed photos of how the tree looks currently.
I called and emailed Greenfield Citrus Nursery about my concerns and here are the ideas I was given:
"The tree looks like it needs some fertilizer. Since you purchased the tree last year, you could add some fertilizer to the tree now. About 3 tablespoons should be sufficient for the amount. Apply the fertilizer at the edge of the drip line. Water the tree on its normal cycle, let the water soak in, then apply the fertilizer. Where is this tree planted? Is it near grass? Do you have a well for the tree about 3 feet wide? You need to have the well clear of rocks, weeds, and other plants. Do you still have the trunk covered with the cardboard to keep the tree from sunburning?
How do you water the tree? . The tree needs deep watered about once a week in the summer, and only about every 2-3 weeks in the winter. With a automatic system, how often does it get watered? This tree needs about 10-12 gallons a week in the summer, and about 6 gallons in the winter, every 2 weeks, altering for the weather, depending on rain or the warming trends we’re having. If the tree gets west and/or south sun during the majority of daylight, it would be good to make a shade screen to the west or south of the tree to help shade it during the summer. The small black spots on the leaves are mineral deposits from the water. Nothing to worry about. You have some curled leaves from “thrip”, which is a tiny insect that gets on the newer leaves of citrus and you “see” the cosmetic damage about 9 months later. You can spray the foliage in the spring and fall to lessen these bugs. Every citrus tree has some thrip leave change, but sometimes the cosmetic effect shows more. Triple Action Plus works well on killing the thrip insects.
Let us know if you have questions.
Thank you for sending the pictures.

HI Chelsea, next time you water the tree, check the soil moisture before you water again. I’m wondering if the soil is draining fast or slow. If the water is setting in the soil longer, then the roots aren’t drying out enough between watering. If the soil is dry between watering, then you may need to increase the watering frequency. Probe the soil with a long screwdriver out from the trunk about 8”, and then probe into the soil about 8” deep at that same point. If the soil is damp enough to hold itself into a ball in your fist, then wait longer until you water the next time. If the soil is dry and flaky when you probe, then the tree may need MORE water. Each area can have a different absorption rate, so it can be difficult to ascertain the tree’s needs. Hope this makes sense. "
