Drew explains of the blueberry bushes: 'Pink lemonade blueberries are a fascinating variety of blueberries. Their fruits start off with a yellow-green color that develops into pink, and they are sweeter than traditional blueberries.'

If you're interested in planting the blueberries, there are several factors to consider. Close attention to the climate, hours of sunlight, and soil acidity are all essential for a successful crop.

First, evaluate the size of your garden, and where you live to determine if blueberries are the right plants for your fruit planting. 'Pink lemonade blueberries are suitable for US hardiness zones 4-8 and can thrive in cooler northern climates, Drew says. 'The bushes are compact and reach 4-5 feet in height, making them suitable for smaller gardens, raised beds, or growing in containers.'

The right balance of sunlight to shade is also essential. Drew advises: 'Plant the bushes somewhere with 5-6 hours of sunlight each day, while pink lemonade blueberries will tolerate part-shade. It prefers an acidic soil with a pH of 4.5 to 5.5, and adding pine needles or oak leaves can help make the soil more acidic.'

Fertilizing blueberries happens less frequently, but is equally important. Drew suggests: 'Feed plants each spring with a fertilizer specially formulated for acid-loving plants.'

As the summer approaches, it's the perfect time to try this new and exciting fruit. Thanks for the inspiration, Carrie!
