Tips for Planting and Caring for Part Sun Perennials

Soil Preparation

Proper soil preparation is crucial for the success of part sun perennials. Ensure that the soil is well-draining and rich in organic matter. Consider adding compost or well-rotted manure to improve fertility and moisture retention.

Watering

While many perennials are drought-tolerant once established, keeping them adequately watered during their first growing season is essential. Water deeply to encourage deep root growth, especially in the early spring and during dry spells.

Mulching

Applying a layer of mulch around your plants can help retain soil moisture and suppress weeds. Organic mulches, such as shredded bark or straw, will also break down over time, enriching the soil.

Pruning and Deadheading

Regular pruning and deadheading can extend the blooming period of your perennials. Remove spent flowers to encourage new blooms, and trim back any dead or damaged foliage to promote healthy growth.
