This species quince is easy to grow from seed. It has one of the largest fruits at our farm weighing in up to a pound and a half each. Seeds that we provide are from our planting of fireblight resistant plants hardy into zone 5. The plants tend to be more upright than tall with this seed selection. By growing this plant over the last 20 years we have found that fireblight really takes a toll on non resistant seedlings and as a result we lost over 75 percent of our planting. Our remaining plants are now we consider resistant or immune to this devastating disease where and when it gets hot and humid in the summer. To germinate the seed: Wash the seed prior to germination. Add moist Canadian peat moss to the seeds and let them set for one week. Then put in the fridge for 60-90 days. Remove and put at room temperature. Some seeds will sprout in 7-10 days. Others may take longer and you might want to put them back into the fridge to get the rest to split open. Treat these like you would pear or apple seeds.
|Genus & Species||Pseudocydonia sinensis|
|Hardiness||-15 to -20F|
|Pollination Requirements||Likely self fertile but not sure 100 percent.|
|Climate||Zone 5ish-Zone 9. Iffy in high humidity due to fireblight.|
|Ease of Cultivation||Easy to grow from seed. Tricky in the fireblight department but it appears our strain is either highly resistant or immune to it so far.|
