Wicking Bucket

Selecting the correct size for your wicking container is crucial for accommodating the specific needs of your plants. From small 1-gallon juice bottles, ideal for individual plants or herbs, to large 35-gallon buckets that can support multiple plants like five tomatoes or peppers, the size impacts how effectively the system can support plant growth. For larger containers, companion planting, such as basil under tomatoes, enhances the benefits by supporting mutual growth and pest control. The key is to match the container size with the plant’s root system and growth potential, ensuring each plant has enough space to thrive while benefiting from the wicking system’s efficient water delivery.

Creating the water reservoir starts with drilling a hole one-third of the way up from the bottom of the container. This step is essential for containers of 2 gallons or larger. The hole marks the top of the water reservoir, allowing excess water to drain, ensuring the soil remains moist but not waterlogged. Safety is paramount when drilling, and adding a screen or a piece of irrigation pipe into the hole can prevent mosquitoes from entering the reservoir. For smaller containers like 1-gallon juice bottles, using a wick to draw water up into the soil from a 3″ pipe can achieve a similar effect, perfectly balancing moisture levels for healthy plant growth.

Ideal fillers include yogurt containers or any food-grade plastic to keep the setup light and safe for growing edible plants.  The goal is to maximize water storage and support the soil above. Gravel is another option, though it increases weight. Cover these fillers with garden cloth to prevent soil from mixing into the water, ensuring a clean reservoir and efficient water usage. Remember to integrate a column of soil that extends to the bottom of the bucket by placing the garden cloth into an inverted holed yogurt container, allows water to efficiently wick up to the soil, maintaining optimal moisture levels for healthy plant growth.

The science of wicking is rooted in the soil’s ability to draw water from the reservoir through capillary action, directly to the roots. Achieving this requires a specific soil composition— a blend of homemade compost, peat moss, dolomite (to adjust pH), and vermiculite to ensure the soil is light and airy, facilitating easy root growth. A balanced mix, occasionally fortified with a 10-10-10 fertilizer at different levels for larger buckets, is vital. Conducting a home soil test can help tailor the mix to your plants’ needs, ensuring a healthy, productive environment in this concentrated growing space.

Creating the ideal soil mix involves blending homemade compost (rich in nutrients from aged chicken manure, straw, and kitchen scraps), peat moss (for structure), dolomite (to neutralize the peat moss’s acidity), and vermiculite (to keep the mix light and prevent compaction). This combination supports healthy root growth and optimal wicking. Testing your soil at home can guide you in adjusting this mix to suit your specific plant needs, ensuring the soil environment is conducive to growth without over-concentration of any component.
