Harvest Tips
Oranges typically ripen November through January depending on region. Fruit is ready when fully colored and slightly soft to gentle squeeze. Clip fruits with pruning shears to avoid damaging branches and tree. Sizzler Oranges will continue to ripen on the tree but do not ripen further after picking. Harvest regularly to encourage more production. One mature container tree (3-5 years old) can produce 20-40 oranges per year.
