Rootstock seed is the foundation of any citrus nursery operation. Seed extraction requires a series of precise steps to insure a uniform product that can be stored for many months without risk of deterioration. We harvest the fruit from our seed trees that are certified Psorosis free by the California Division of Food and Agriculture (CDFA) and follow a 10-step process to extract and clean the seed. At TreeSource we package our seed in 1 and 2 liter bags that are heat sealed to reduce the risk of contamination during storage. All seed is heat treated and dipped in fungicide to eliminate contamination.

To determine the quantity of seed you require look up our seed counts per liter chart. Seed counts per liter vary slightly from year to year, but the chart shows you a solid average for each rootstock type we supply. We sell all our seed by volume since weight is a poor way to sell citrus seed since moisture content can influence weight so dramatically.

Rootstock seed is harvested from November to February and can be stored without a significant impact on germination percentage for 5 to 6 months. Supply varies from year to year and orders are accepted based on availability. Contact Us for information on pricing and availability. Payment in advance is required for all seed shipments out of California.
