What Plants To Grow In Your Backyard Aquaponics Garden

Most people start their aquaponics garden for fresh, organic produce. You can raise other types of plants, but vegetables are the most common plant to grow. Once your garden is up and running, it is possible to keep you and your family in fresh vegetables all year round.The question is, what plants to grow in your backyard aquaponics garden?  

With a typical vegetable garden, you plant the seeds in the soil, you water those seeds, you fertilize those seeds, you pull the weeds around those seeds, and eventually you see your plants push through the ground.  This is a time and resource-draining process, all with the hopes of seeing your garden flourish. 

With an aquaponics garden, the watering, the fertilizing and the problem with weeds is taken care of by the system. You don’t need to water as there is a constant supply of water for your plants. You don’t need to fertilize as the fish are supplying the waste that is processed into nitrogen rich fertilizer. Weeds are not a problem in an aquaponics garden. Your main job is making sure you feed the fish!

Some things to consider

Climate. If you are growing outside you need to stick with plants that grow well in your climate.  Plants do better when they are in temperatures that match their normal growing process.  If you want a year-round garden just make sure you are growing cold weather plants in the winter and warm weather plants in the summer. 

Where to plant. It is crucial to the success of your aquaponics garden that you choose the right place to plant. Make sure there is enough sunlight for they types of plants you are raising. Consider other outdoor conditions where you live. If it is really windy you need to consider setting up your garden where there is some shelter from the wind. 

Schedule.  It is really exciting when your plants start to grow and produce vegetables, but, you need to consider scheduling your planting. You don’t want so much produce that you can’t use it all. Stagger your growing times so you always have just enough but not too much produce. 

Fish. Make sure the fish you are using are compatible with the plants your want to grow. If you are using a fish that likes the cold but want to raise a plant that likes it warm, you won’t be successful.
