Utilizing Common Household Items for Filling Large Planters: Garden Experts' Time-, Money-, and Effort-Saving Strategies
Kezia Reynolds, our new News Writer, joined the platform team in September 2024, and she's already on the lookout for the latest home news, finding you the best deals and trends. Today, we're sharing some expert-approved alternatives to using potting soil for filling the bottom of a large planter.
First, let's talk about common practices. Hayden Salt, head gardener at Jacksons Nurseries, suggests using broken pots to prevent compost from being lost through large drainage holes. Cans should be placed upside down or laid on their side to prevent filling up with water. In particularly large planters, Hayden suggests using rocks or gravel, while Graham Smith MCIHort, a gardening expert from LBS Horticulture, suggests upcycling food tins by cleaning them out and crushing them to fill the bottom of a large planter.
However, for those seeking a more sustainable and effective solution, there are several alternatives to consider.
- Rice hulls: These natural husks improve drainage and soil aeration while breaking down over time to add organic matter. They are sustainable and neutral pH, making them suitable for most plants. Mix 10-50% with potting soil or use as a bottom layer for improved drainage.
- Perlite: A widely used lightweight volcanic mineral that boosts aeration and drainage when mixed with soil. It does not break down and helps prevent soil compaction.
- Coarse materials such as expanded clay pellets or small gravel: These add weight and create air pockets for drainage at the planter bottom, preventing waterlogging and root rot.
- Clear stone or crushed rock: Often recommended like in French drains for drainage. Placing a layer on the bottom allows excess water to flow away from roots, improving drainage and stabilizing the planter.
It's important to note that garden soil or untreated heavy soils at the bottom are generally not recommended because they can compact and impede drainage. Instead, lightweight, porous, or coarse materials like those above are preferred by gardening experts to enhance planter drainage and stability.
These approaches help balance moisture retention in the upper soil layers while preventing excess water buildup at the roots, promoting healthier plant growth. Remember, when using plastic containers or bottles, it's best to use old ones or non-edible plants, as there's a chance that the plastic will break down and release chemicals into the soil.
So, whether you're a seasoned gardener or just starting out, these expert-approved solutions can help you maintain a healthy and thriving garden. Happy planting!
