Outdoor Planting Instructions: Choose a spot in your yard that receives at least 6 hours of sun every day. Make sure the soil is well-drained and the area is free from grass, which will compete for water and nutrients. Dig a hole in the ground that is twice as wide as the root ball. Place your tree in the hole, with 1 inch of the root ball sticking out from the top of the soil. Water thoroughly after planting. Add a thick layer of mulch around the base of the tree, but keep the mulch 6 inches away from the tree trunk.

Container Planting Instructions: Plant your tree in a small container, slightly larger than the root ball. Plant in well-draining soil and make sure your container has proper drainage holes. Place a layer of rocks on the bottom of your container to aid in drainage, then add your soil and tree, making sure the tree stands vertical and upright. Bring your tree inside when the temperature reaches below 50 degrees Fahrenheit.

Watering: You only need to water your tree when the soil is dry. For trees planted in the ground, check the soil at a depth of 5 inches. For container plants, check the soil at a depth of 2 inches. Depending on the humidity in your area, you will likely only need to water your tree once a week. The roots of the orange tree are wide, so be sure to water past the drip line for trees that are planted in the ground.

Fertilization: You will need to add a citrus fertilizer to your tree during its harvest. When you begin to see fruit, apply your first round of citrus fertilizer according to package directions for the size of your tree. Add additional doses of fertilizer every month or two during the entire harvest season. You will also need to add a dose of fertilizer twice during the dormant season. As your tree matures, you can increase the time between dosing during the harvest season, and you can skip the dormant fertilization all together.

Pruning: You can prune your tree to shape as a bonsai, if desired. The Chinotto responds very well to pruning. You can trim back as much of your tree as you wish, keeping enough of the living branch to encourage new growth. Prune just as new growth appears.

Pests: When watering your tree, spray the leaves and branches with a hose to knock off any larva or eggs. If you see any eggs, larva or worms sprayed off, be sure to put them in a sealed trash bag and throw them away to prevent them from re-inhabiting the tree. Keep the area around your tree free from grass and prune off any branches that touch the ground. These measures will prevent ant infestations. You may also spray your tree with insecticidal soap at the beginning of the harvest season. If your tree becomes infested, you will need to use an insect oil to rid the tree of pests and prevent diseases.

Harvesting: Remove fruit as soon as it has ripened on the tree. to prevent pests, remove all fruit from the tree before it falls and rots.

Storage: Once picked, Chinotto oranges will not continue to ripen. You can store oranges in your pantry for up to a week. However, Chinottos will also stay fresh in the refrigerator for a month. You can eat your fruit fresh, but it is not recommended, as the taste is unpleasant. However, Chinottos are great for marmalades, candy making and cooking.
