Oregon grape

Oregon grapes should be watered regularly but sparingly. The best way to water this plant species is to water deeply and infrequently. In other words, it's best to saturate the soil with water and allow the top inch of soil to dry out between waterings. This should be done once a week during the spring and summer, and every 2 weeks in the fall and winter. Do not allow the soil to remain soggy- it is better to underwater than to overwater. Also, water directly at the base of the plant instead of using a sprinkler to water the entire area - this reduces the chance of fungal diseases. Too much water can kill the plant. Make sure to avoid overhead watering as this can also cause disease or fungus. When watering indoors, use tepid water to avoid temperature shock. Oregon grapes prefer acidic soils and given that you use the right fertilizer, moderate watering will prevent the soils from becoming too acidic.

Oregon grape requires full sun or partial sun (6-8 hours of direct sunlight daily). It prefers to be planted in the sunniest part of the garden, especially east or west-facing, or sheltered from the north wind. Although it will grow in partial shade, a plant receiving less than 6 hours of direct sunlight will likely not produce an abundance of berries and may be more prone to fungal and disease problems. In its natural habitat, this plant needs direct sunlight 90% of the time, so placing it in a place with direct exposure is recommended for optimal growth and performance.

Oregon grape should be pruned during the early spring months, just as the flowering period is beginning. This will ensure that new growth of the Oregon grape is encouraged. Pruning should be done lightly, removing only dead, damaged or overly crowded branches. Any branches that cross or rub against each other should be removed. Pruning should be done gradually, year after year, as the Oregon grape forms its desired shape. Over-pruning should be avoided, as this can negatively affect the shape and health of the plant.
