4-H Citrus Tree Project Information

The Central Florida Fair 4-H Citrus Tree Contest has been in operation for more than twelve years. There are a number of objectives, one of which is to have an increased awareness of the Central Florida citrus industry. A key part of the project is the citrus grower, processor, packer, and support industries which purchase the trees.

Citrus Tree Contest Details

Each contestant will be given the opportunity to choose his or her own tree. Once trees have been selected, no substitutions will be allowed. Only trees from the original group will be eligible for exhibition in the fair.

Tree Judging

Prior to the Central Florida Fair, each tree will be pre-judged and classified as blue, red, or white by qualified judges. All trees must be taken home. Blue-rated trees will be eligible to be "shown" by the exhibitor. During this final judging process, exhibitors should be prepared to answer questions related to the care of their trees.

What Makes A Blue Ribbon Citrus Tree?

These are the factors that go into judging a blue ribbon tree:

  • Height
  • Width of trunk & good sturdiness of tree
  • Very well formed canopy –Branches plentiful and uniform
  • Dense foliage and good foliage color (no deficiencies)
  • Leaf shape and size
  • Straight trunk
  • Sprouts cleanly removed
  • Free of insects and insect damage
  • Free from disease signs and symptoms
  • Free of cold injury

These factors are not ranked necessarily in order of importance as they are all important traits to producing an award winning tree.

Project Book Judging

Project books must be submitted by all CFF Citrus Contest participants. During prejudging books will be screened for completion. An exhibitor whose project book does not meet completion criteria will be ineligible to enter the tree in the CFF. Junior and Senior project books will be judged separately according to completeness, accuracy, and overall neatness.

Knowledge Test

All participants MUST take the knowledge test. Contestants will be required to ID varieties of citrus, parts of a tree, diseases, nutritional problems, and to answer questions relating to tree care and the citrus industry. Participants may take the test regardless of whether a tree is entered for judging. For the 2011-2012 Knowledge Test, study the following carefully:

Also recommended look over the resource section and Care of Your Tree under Contest Materials

Tree Sale

Blue ribbon trees will be for sale to the public during the fair. Sale of trees is optional. Please note your desire at time of check-in. Contest coordinators will attempt to recruit potential buyers for trees, but exhibitors are ultimately responsible for recruiting their own buyers.

Points to Writing a good Thank You Note to Buyer

Step 1: Include the Proper Information

You'll need to know a few things before you send off a thank you note to your buyer. You should also be aware of the exact spelling of your buyer's name. Finally, it's a good idea to have a bit of background information handy about your tree or your relationship with the buyer, as this will help you to be able to add a more personal touch to the thank you note.

Step 2: Format the Note Properly

Thank you notes are not only a good way to show your buyers that you care about them and their support of your prohect, but to also demonstrate that you are professional and responsible. Format your thank you note as you would a professional business letter. Include your name, company name, and contact information at the upper left corner of the thank you note. In the upper right corner, include the date that you'll send the note to your buyer. Leave a single space below the contact information, then begin the body of your letter (being sure to include the proper salutation).

Step 3: Write Thoughtfully and Genuinely

Take some time to consider how you might write the body of your thank you note. It doesn't need to be excessively long, but it should be personalized to that specific buyer and show that you genuinely appreciate her and her business. Include your excitement for continuing to work with that buyer in the future.

Step 4: Sign the Note

Include a space at the bottom of the body of the letter where you can sign it yourself. This adds a nice personal touch to the letter.

Step 5: Mail the Note Promptly

Make sure that you complete and mail the note promptly after you have interacted with your buyer. If possible, print the letter on nice paper or another official piece of stationery. Before you mail the note, take the time to read over it once again to make sure that there are no typos or grammatical errors that might get in the way of the delivery of your message.

2011/2012 Variety

Navel Orange

Navel orange is an excellent fresh fruit, which tends to bear small crops of large fruit. It usually averages around 3-3.5 inches in diameter. It tends to be low seeded, with seed counts between 0-6 seeds per fruit. It is commercially harvested between October-January, but tends to have the best flavor between Thanksgiving and Christmas. The fruit tends to be lower in acid than most orange varieties.


This rootstock selection originated from a cross of Siamese pummelo (Citrus grandis) x Gotha Road Trifoliate Orange (Poncirus trifoliata). In all field evaluations,US-802 rootstock yielded vigorous and prdouctive trees that were tolerant to endemic disease and pest problems and exhibited excellent survival. The major positive attributes of this new rootstock are resistance or tolerance to citrus trite virus, citrus blight, Phytophthora palmivora dna Diaspreses root weevil, induction of high vigor and good fruit productivity on grated scions and ease of seed propatation. Notable negatives may be the tendency for trees grafted on US-802 rootstock to become very large and produce fruited with intermediate or low soluble solids concentration.
