Where to Plant Annual Plants

Low-maintenance annual flowers thrive in full sun with well-draining soil. When preparing your garden beds or containers, make sure to select a spot that receives at least 6 hours of direct sunlight per day. Annuals love the warmth and will produce the most blooms when grown in sunny locations.

It's also critical that the soil drains well. Standing water can cause root rot and other fungal diseases. Test your soil drainage by digging a small hole 12 inches deep, filling it with water, and observing how quickly it drains. The water should dissipate within an hour. If it takes longer, work in 2-3 inches of compost to improve drainage. Raised beds also promote drainage.

For container gardening, use a high-quality potting mix and make sure your containers have drainage holes. Self-watering pots are another great option for annuals. With the right sun exposure and well-drained soil, your low-maintenance flowers will thrive beautifully all season long.
