What are the best plants to avoid in cedar wood outdoor flower pots due to soil acidity?

Cedar wood outdoor flower pots are popular for their durability and natural beauty, but their acidic soil can be problematic for certain plants. Cedar naturally releases tannins and acids, which lower the soil pH over time. This makes it unsuitable for plants that prefer neutral or alkaline conditions.

Here are some plants to avoid in cedar wood pots:

1. Lavender – Thrives in alkaline soil and struggles in acidic conditions.

2. Boxwood – Prefers neutral pH and may yellow in acidic soil.

3. Clematis – Requires well-balanced pH and may suffer in cedar pots.

4. Lilacs – Need alkaline soil for optimal growth and blooming.

5. Peonies – Perform poorly in acidic environments.

Instead, opt for acid-loving plants like hydrangeas, azaleas, or ferns, which will thrive in cedar wood pots. Regularly test soil pH and amend it if necessary to maintain a healthy garden.
