How to Grow Dahlia Perennials

Growing Dahlia perennials requires some preparation and care, but the end result is worth it. Here are the steps to grow these beautiful plants:

Choosing a Location for Your Dahlias

Dahlia perennials prefer full sun exposure but can also grow well in partially shaded areas. It’s important to choose a location that has good drainage as these plants do not like wet soil. Avoid planting them in low-lying areas or where water tends to pool.

Preparing Soil for Planting

Before planting your Dahlia perennials, it's essential to prepare the soil. These plants require well-draining soil with a pH range of 6.0 - 7.5. If your soil is heavy clay or compacted, add organic material such as compost, peat moss or aged manure to improve the soil structure and fertility.

Planting Dahlia Tubers

The best time to plant your Dahlia tubers is after the last frost has passed and the soil has warmed up. Dig a hole that is about six inches deep and twice as wide as the tuber. Add some bone meal or fertilizer to the bottom of the hole and place the tuber in the hole with the stem facing up. Cover the tuber with soil, leaving only the top part visible above the ground.

Watering and Fertilizing

Dahlia perennials need regular watering, especially during hot, dry weather. It's best to water your plants deeply once or twice a week rather than shallowly every day. Dahlia perennials also benefit from regular fertilization to promote healthy growth and blooming. Use a balanced fertilizer that is high in phosphorus but low in nitrogen.

Supporting Dahlia Plants

As your Dahlia perennials grow taller, they may need some support to prevent them from bending or falling over. You can use stakes or garden twine to hold them up. Make sure you tie them loosely to avoid damaging the stem.

Pruning and Deadheading

To encourage more blooming and maintain a tidy appearance, it's important to deadhead your Dahlia perennials regularly. Snip off the faded blooms as soon as they wilt or turn brown. Additionally, you can prune your plants to control their shape or size. Cut back any unruly branches, especially those that are touching the ground.

Overwintering Dahlia Tubers

Dahlia perennials are not frost-tolerant, so you'll need to dig up the tubers if you live in an area with harsh winters. Wait until after the first frost has killed off the foliage then carefully dig up the tubers. Clean them off and let them dry for a few days. Store the tubers in a cool, dry place over the winter and replant them in the spring.

With their stunning blooms and long blooming season, Dahlia perennials are an excellent addition to any garden or landscape. By following these tips and tricks, you can easily grow these beautiful plants with ease.
