In our vertical gardens, it’s essential to fertilize the plants regularly as they may not have access to all the nutrients they need from their limited soil space. As a general rule of thumb, I recommend feeding your plants every 4-6 weeks during their growing season with a balanced, water-soluble fertilizer. It’s important that we choose an appropriate formula specifically designed for container gardening since these will provide the right mixture of nutrients tailored for our vertically grown friends. Don’t forget to follow the instructions on the package and adjust accordingly based on your plant variety and environmental factors – after all, we want to keep them happy and healthy so they can continue brightening up both our spaces and lives!
