Fuchsia do well with companion plants whose root systems help hold in moisture and nutrients in the soil. Since fuchsia plants are partial-sun loving plants, planting vegetation that thrives in the shade along with your fuchsia will greatly benefit the aesthetic value of the blooms and foliage altogether, and it will also help your fuchsia grow as it needs to.
Planting ferns or begonias near your fuchsia is a good idea because the root systems are known for helping to hold in moisture. You can help your fuchsia out just by putting one or two of these plants near it. Make sure that when you space them apart, you’re keeping them close enough to be companion plants, but that they’re not close enough to hinder one another—this will depend on each individual species of plant you choose to put next to your fuchsia.
Planting other shade tolerant plants like purple heart and Japanese maple will also help the fuchsia grow because while these plants are different from ferns and begonias, they are great plants to help fight erosion from rain and wind. They also hold their shape as long as you care for and prune them regularly, and they don’t grow all that quickly either. There have been Japanese maple trees that seem to stay the same size for decades, and this can benefit your fuchsia because the consistency lends a constant root support.
Remember that when you companion-plant vegetation or trees with your fuchsia to choose plants that require the same environment as your fuchsia, because you don’t want to contaminate one with one kind of fertilizer and vice versa. You also don’t want to put a plant in the soil next to your fuchsia that requires a different pH level than the fuchsia, so make sure you plant something that does require the same kind of environment.
Also make sure that whatever you plant with your fuchsia isn’t in direct competition with it. You don’t want your fuchsia to wither off and die because the companion plant has taken all of the nutrients away from your fuchsia. You also want to make sure that whichever plant you choose, large or small, that you keep your plants correctly spaced. It might help if you put up an edging of sorts between the two plants, like a circle of large rocks to keep the plants from growing into one another.
Finally, make sure that their watering requirements are the same. Fuchsia needs very exact watering circumstances, and if you put something next to it that can’t handle that amount of water or needs more, you will surely run into problems when the soil above both of them is either too dry for one or too wet for the other! Make sure that you address this situation quickly by reading the tags that come with each plant you purchase from the nursery.
