What to Consider When Purchasing the Best Potting Mix for Indoor Plants

Your‌ ‌Plant's Needs‌: When selecting the proper potting soil mix for your plants, it's important to know your particular plant's needs. Some plants like succulents and cacti require well-draining soil that quickly drains excess moisture to prevent problems like root rot due to overly wet conditions. When it comes to succulents or cacti, it's best to use a succulent or cactus mix with proper drainage. Other plants can prefer a soil mix that retains some moisture, so a mixture with moisture retention qualities comes in handy and alleviates the need for constant watering. You can also find other specialty soil mixes for specific plants like orchid potting mixes, African violet potting mixes, as well as those for citrus and tropical plants, and those formulated for seed-starting.

Potting Mix‌ ‌vs.‌ ‌Potting Soil‌: When it comes to container plants, whether for your houseplants or outdoor plants, it's always best to go with a potting medium that has good drainage. Potting mixes aren't as heavy as potting soils, which can lead to soil compaction and the soil retaining too much water leading to root rot problems. Most potting soils don't drain as well as potting mixes making them unsuitable for use inside containers. Heavy soils rob the plant roots of much-needed oxygen, which leads to problems with disease and can eventually lead to the plant's death.

Organic Material‌: Unless you are starting seeds, make sure to use an organic potting mix that contains organic soil amendments that will assist your plant's needs in gaining nutrients. Some potting mixes contain an organic fertilizer like earthworm castings, meaning the soil mix will continue feeding your plants for around three months. They eliminate the need to regularly feed your plants with supplemental fertilizer to promote healthy growth.
