Soil Preparation

Proper soil preparation is essential for healthy plant growth and abundant blooms. To prepare your soil, loosen it and add organic matter such as compost or manure for best results. This will enrich the soil in a natural and beneficial way, making it more fertile and well-draining for your perennials.

Compost and other amendments can be easily incorporated into the soil by tilling or digging them in. This will ensure good drainage, adequate nutrients, and available water for your perennials to thrive.

By taking the time to properly prepare your soil, you’ll create an ideal environment for your summer-blooming perennials to flourish.

Watering and Fertilizing

Regular watering and fertilizing are crucial for helping your perennials thrive and produce more flowers. Soak your plants immediately after planting and regularly check to ensure they don’t dry out. For established plants, aim to provide one inch of water per week, using deep but less frequent waterings to help your perennials develop strong roots.

When it comes to fertilizing, using a natural, organic fertilizer is the best way to ensure healthy plants without burning them. Fertilize your perennials twice a year, at planting time and in early fall, for optimal growth and health.

With proper watering and fertilizing techniques, your summer-blooming perennials will be poised to produce an abundance of beautiful blooms.

Deadheading and Pruning

Deadheading and pruning are great techniques to help promote new growth and extend the blooming period of perennials.
