How Long Does it Take to Grow Cydonia Oblonga (Quince) Bonsai?

Cydonia Oblonga is a self-fertile plant and often takes five to six years to produce the first fruits. However, the tree may take up to ten years for maximum production. They can tolerate a wide range of soils but grow well in deep-fertile and moisture-retentive soils. The trees dislike water logging especially in winter and always enjoy warm and sunny areas.

Positioning and Lighting

Position your Cydonia Oblonga (Quince) Bonsai tree in full sunlight with good aeration away from the dry winds. Ensure the tree is facing south or west and positioned in a warm place. Proper positioning of this plant in the light makes the trees pests- and disease-free offering the best blossom. You can also position the Quince tree in semi-shades or full-shades to sustain, but the tree may not produce fruits in semi-shades and full-shades.

Temperature requirements

Cydonia Oblonga (Quince) prefers hot summers and grows optimally at 15℃. However, they can tolerate the temperature to about -15℃. Fruits will ripen in cold weather but not in cool summers. They are sensitive to strong winds, cold, and should be placed in sheltered places with good sunlight.

Watering needs

A Quince tree is not drought-tolerant, and they need to be watered as soon as the soil is dry. The tree might sustain for a couple of weeks without water. However, it required deep watering once a month. Always water depending upon the outside temperature. Overwatering may invite fungal disease and insufficient watering may cause fruit drops.

Otherwise, you can also use semi-ripe cuttings in mid-to-late- summer. Hardwood cuttings are preferable in winter.

Pruning and Wiring

Prune damaged and dead branches after the last frost. Remember that the fruits grow on old growths or branches, so cautiously prune the tips of the branches. Prune the overcrowded branches and branches that show little growth or no growth. Always remove suckers around the tree base. Eliminate unwanted shoots from the main stem. Stop pruning after mid-summer so as not to compromise the flowering of the coming year. As flowers and fruits are produced on the same shoots, the tree needs new wood every year.

The ideal time for wiring the Cydonia Oblonga (Quince) tree is in autumn. You can also wire young shoots in summer. Older twigs are stiffer and younger twigs are easy to shape. Wiring in the first couple of years helps the bonsai to grow in the desired shape offering a strong root base.

Pluck the fruits from this bonsai only when they are mature and not fully ripe. They continue to ripen when the fruits are off the tree. Following this process reduces fruit dropping from the tree. Use a sharp knife or cutting tool to pluck the fruits from the tree. Don’t simply pull the fruit because this may cause damage to the twigs.

The fruits are ready to harvest in October or November when they transform their color from light yellow to dark golden color.
