What Houseplants Like Acidic Soil: Houseplants not only add beauty and a sense of tranquility to your home but also have numerous health benefits, such as improving air quality and reducing stress. However, different plants have different soil needs, and it is essential to understand this to keep your plants healthy and thriving. For example, did you know that certain houseplants prefer acidic soil? With around 30% of the world’s soil being acidic, it is essential to know how to manage this type of soil for your houseplants.
Understanding Soil PH and Its Importance
Soil pH is the measure of the acidity or alkalinity of the soil. On a scale of 0 to 14, a pH of 7 is neutral, below 7 is acidic, and above 7 is alkaline. Soil pH is crucial for houseplants as it affects the availability of essential nutrients in the soil. Most houseplants prefer a slightly acidic to neutral soil pH, but there are some plants that thrive in more acidic soil. Acidic soil helps certain houseplants absorb nutrients more efficiently, as some nutrients, like iron and manganese, are more available in acidic conditions. In addition, acidic soil can help prevent the growth of harmful pathogens that thrive in alkaline conditions. So, if you’ve been wondering “What houseplants like acidic soil?”, read on to discover some popular and lesser-known houseplants that thrive in acidic conditions.
Top Acid-Loving Houseplants
- Gardenia (Gardenia jasminoides): This popular houseplant is known for its fragrant, white flowers and shiny, dark green leaves. Gardenias prefer acidic soil with a pH between 5.0 and 6.0.
- Azalea (Rhododendron spp.): Azaleas are another popular choice for gardeners looking for acid-loving plants. They prefer soil with a pH between 4.5 and 6.0.
- Blueberries (Vaccinium spp.): Although not a traditional houseplant, blueberries can be grown in containers and prefer acidic soil with a pH between 4.0 and 5.0.
- African Violet (Saintpaulia): This beautiful flowering plant prefers a slightly acidic to neutral soil pH, but can also thrive in more acidic conditions.
- Peace Lily (Spathiphyllum): This popular houseplant prefers slightly acidic to neutral soil, but it can also tolerate more acidic conditions.
- Ferns: Many species of ferns, such as the Boston Fern (Nephrolepis exaltata), prefer acidic to neutral soil.
- Camellia (Camellia japonica): This flowering shrub, which is often grown as a houseplant, prefers acidic soil with a pH between 5.0 and 6.5.
Lesser-known Acid-Loving Houseplants:
- Fuchsia (Fuchsia spp.): Fuchsias prefer slightly acidic soil, and their colorful flowers can add a pop of color to your indoor garden.
- Pitcher Plant (Nepenthes spp.): This carnivorous plant prefers acidic soil and is a unique addition to any houseplant collection.

Make sure to also check the pH level of your soil regularly and adjust it if necessary to ensure your houseplants are getting the nutrients they need to thrive. Regularly monitoring and adjusting your soil pH is an important part of houseplant care.
How to Test and Adjust Soil PH
Testing the pH of your soil is essential to ensure that it is the right acidity for your houseplants. There are several ways to test soil pH at home, from DIY methods using household items to pH testing kits available at garden centers. One popular DIY method is the vinegar and baking soda test. To do this, take two soil samples from your garden and add half a cup of vinegar to one of them. However, for more accurate results, it’s best to use a soil pH testing kit or a digital pH meter.
If your soil is not acidic enough for your plants, you can make it more acidic by adding organic matter like peat moss, pine needles, or coffee grounds. You can also use sulfur-based products like elemental sulfur or aluminum sulfate. Just be sure to follow the manufacturer’s instructions carefully and test the pH again after adding any amendments to ensure it is at the correct level. What houseplants like acidic soil might not thrive if the acidity is too low or too high.
Tips for Growing Acid-Loving Houseplants
Proper care is essential for growing acid-loving houseplants successfully. Here are some tips to keep your plants happy and healthy:
- Watering: Acid-loving houseplants generally prefer well-draining soil and should be watered when the top inch of soil feels dry to the touch. It is also a good idea to use rainwater or distilled water, as tap water can often be alkaline and raise the soil pH over time.
- Light: Most acid-loving houseplants prefer bright, indirect light, although there are some, like azaleas, that prefer partial shade. Make sure to research the specific light requirements of your plants and adjust their placement accordingly.
- Temperature: Acid-loving houseplants typically prefer cooler temperatures, so try to keep your home between 60-75°F (15-24°C). Avoid placing your plants near radiators or heating vents, as this can dry out the soil and harm the plants.
- Fertilization: Use a fertilizer specifically designed for acid-loving plants, as it will contain the nutrients they need to thrive. Follow the manufacturer’s instructions carefully, and that it is better to under-fertilize than over-fertilize.

Common Mistakes to Avoid
Caring for acid-loving houseplants can sometimes be a tricky affair, and mistakes are bound to happen. Here are some common mistakes people make and how to avoid them:
- Over-watering: This is the most common mistake made by plant parents. Over-watering can lead to root rot and other fungal diseases. To avoid this, make sure the soil is well-draining and only water your plants when the top inch of soil feels dry to the touch.
- Using the wrong soil: Not all soil is created equal! Using the wrong type of soil can lead to nutrient deficiencies or toxicities. Make sure to use soil specifically designed for acid-loving plants or make your own using the recipes below.
- Over-fertilizing: More is not always better! Over-fertilizing can lead to nutrient burn and harm your plants. Use a slow-release fertilizer specifically designed for acid-loving plants and follow the manufacturer’s instructions carefully.
- Ignoring pH levels: The pH level of the soil is crucial for the health of acid-loving plants. Regularly test the soil pH and adjust it if necessary to keep it in the optimal range.
DIY Acidic Soil Recipes
Making acidic soil at home is easier than you might think and can be a cost-effective alternative to store-bought soils. Here are two simple recipes to get you started:
- Recipe 1:
- 1 part peat moss
- 1 part well-rotted compost
- 1 part coarse sand or perlite
- 1 tablespoon of elemental sulfur per gallon of mix
- Recipe 2:
- 2 parts pine bark or pine needles
