General Description |
A very tall, wide tree. |
Landscape |
Only suitable for very large gardens. |
Cultivation |
Grow in full sun or partial shade in deep, fertile, moisture-retentive soil. A. hippocastanum can withstand drier, poorer soil and is more resistant to exposure and pollution. |
Shape |
Has a broad, spreading, and domed crown. |
Pests |
Extensive leaf blotch (Guignardia aesculi) but does little damage to the tree since it occurs late in the season and hence does not warrant control. Symptoms are irregular brown blotches with light yellow borders, with severe infections causing premature leaf drop. Remove and dispose of all fallen leaves in the autumn, do not compost. Prone to horse chestnut leaf miner ( Cameraria ohridella). |
