Care Tips for Plants to Help Keep Flies Away
While every plant will have specific needs, it is important to identify these for the species that you are cultivating.
Pots and Containers for Plants That Keep Flies Away
Select the best container with good water drainage. Plant pots need holes in the bottom so excess water can drain, and they need to be the correct size.
Pots that are too small mean plants can easily become root-bound and fail. Pots that are too big will end up with waterlogged soil, because there are not enough plant root to absorb the water.
Soil and Growing Medium for Plants That Repel Flies
Choose quality potting soil or mix. Avoid using outdoor garden soil from your yard as it may already contain insects, fungus, or bacteria.
Water for Plants That Repel Flies
Water plants in moderation. If you water too much, your plant will drown, but if you water too little, it will wither and die.
Test the dryness level of the top couple of inches of soil with your finger. If it feels dry and a bit crumbly, it’s probably time to water.
Light for Plants That Repel Flies
The amount of light a particular plant requires varies, so you’ll want to research plants you’re looking at growing. Some plants need full sun exposure all day, while others will do better in partial shade.
Pets at Home
Pets and plants don’t usually mix. Keep pets away if you’re growing poisonous houseplants. Pets can destroy plants while digging or playing, or they may eat a plant and ingest poisonous parts, resulting in a trip to the veterinarian.
Information and Growing Tips
Research about the best indoor plants and how to grow them, so you can grow them successfully to repel flies. Once you’ve selected a plant or plants, learn as much as you can about raising them, including soil types, sun requirements, preferred temperatures, and watering needs.
