Many plants prefer acidic soil, which typically has a pH level between 4.5 and 6.5. Here are some examples of plants that are known to do well in acidic soil:

Rhododendrons and azaleas: These shrubs are known for their showy blooms and prefer soil that is acidic, well-draining, and rich in organic matter.

Blueberries: Blueberry bushes prefer soil that is acidic and well-draining, with a pH level between 4.5 and 5.5. They also need consistent moisture and can benefit from a layer of mulch to help retain moisture.

Camellias: These evergreen shrubs are prized for their glossy green foliage and showy flowers, and prefer soil that is acidic, moist, and well-draining.

Hydrangeas: Some species of hydrangeas, such as the bigleaf hydrangea, prefer soil that is acidic, while others prefer neutral or alkaline soil. Acidic soil can help to maintain the blue color of the flowers, while alkaline soil can cause them to turn pink.

Ferns: Many species of ferns prefer soil that is acidic and well-draining, with a pH level between 5.0 and 6.0. They also prefer consistent moisture and can benefit from a layer of organic mulch.

Pine trees: Many species of pine trees prefer acidic soil and can help to acidify the soil further with their fallen needles.

These are just a few examples of plants that prefer acidic soil. It's important to note that while some plants may prefer acidic soil, they may not tolerate soil that is too acidic or too alkaline, so it's important to test your soil and make adjustments as needed.
