Companion planting can really transform the way we think about our gardens, not only in terms of space efficiency but also biodiversity. One of my favorite combinations is carrots and onions. They seem to work well together because the smell of the onions can deter carrot flies, while the carrots benefit from the loosened soil due to onion growth.
When it comes to vertical gardening, I've found that using trellises made from bamboo or metal grids helps support heavier climbers like cucumbers or tomatoes. You might also experiment with a simple A-frame structure using old ladders or wooden frames—these are surprisingly sturdy and can accommodate multiple types of plants.
Soil health management in a mixed planting is crucial. In addition to crop rotation and composting, I've started using a mix of cover crops like clover or vetch in the off-season. They fix nitrogen in the soil and provide a natural mulch when tilled into the ground.
As for pest control, creating a balanced ecosystem is key. Introducing beneficial insects like ladybugs or lacewings can naturally reduce aphid populations. Companion plants like nasturtiums can also act as a trap crop to protect more vulnerable veggies.
Have you looked into companion plants that might attract pollinators as well? This can significantly boost both the health and yield of your garden while supporting local ecosystems. If you want more details on constructing specific vertical gardening setups, I'd be happy to share plans or additional resources!
