Insufficient water results in fruit drop.
Overwatering can lead to the onset of fire blight.
Temperature and Humidity
Quince trees prefer warm, sheltered spots to grow.

High nitrogen content and providing too much fertilizer will invite disease into the tree.
Fruit ready to harvest will also be very fragrant, intensifying as they mature.

Codling moths are frequently found on fruit trees, including apple trees.
You may need to trap them and follow up with pesticide spray if the numbers are large.
This ooze will turn black and will leave marks on the tree as it runs down the trunk.
Fresh blooms on trees are the most prevalent infection sites and remain so as the petals fall.
Flowers that have been diseased will wilt and become discolored.
Fire blight can spread into limbs, trunks, or root systems and can kill vulnerable host trees.
Copper solution sprays are the only materials available on the market to consumers for fire blight control.
In its raw state, quince fruit is bitter and acidic.
Cooking (poaching) the fruit removes the sour taste and makes it much sweeter.
Typically, the skin of quince fruit is not edible.
This fruiting tree can be easy to grow because it requires little maintenance and care.
It’s a hardy plant that’s also hard to kill.
The common quince tree is adaptable to many soils though it thrives in well-draining, fertile soil.
This tree does not like soggy soil.
