Alcock's spruce

Alcock’s spruce (Picea alcoquiana 'Howell's Tigertail') requires regular watering during the warmer months of the year, from spring through to summer. During these months, water the plant deeply, and allow the soil to completely dry out before watering again. Watering once or twice a week should be adequate, but the exact frequency may vary according to the temperature and humidity levels in the environment. Containerized plants may require more frequent watering. During the cooler months of autumn and winter, the plant should be given much less water. Wait until the top 1 inch of soil is dry before watering again.

Alcock's spruce (Picea alcoquiana 'Howell's Tigertail') should be grown in a full sun location in order to receive the optimal amount of sunlight. This species enjoys direct sunlight in the morning and afternoon for a minimum of 6 hours each day. Avoid locations which receive too much hot afternoon sun which may cause the tree to become scorched. In more temperate climates, the tree will respond positively to a little more light than the minimum recommended amount.

Alcock's spruce (Picea alcoquiana 'Howell's Tigertail') should be pruned in mid to late spring after the new growth has emerged. Pruning should only be done once a year to promote shape and maintain the desired size. When pruning, avoid cutting back more than 25% of the foliage. For larger pruning tasks, such as a crown reduction, it is best to spread the task out in a few shorter pruning sessions over the course of 2 to 3 growing seasons. Young plants need not be pruned.
