Wondering how you can keep the most pest-free Garden possible? Read on to understand where your pests come from and how you can keep a pest free environment for your Indoor Garden.
Be cautious + inspect outside plants
The easiest way to stop pests from ever entering your garden in the first place is to keep outdoor plants, potted plants, or anything else in soil away from your Rise Garden. Most of the time, pests enter your house through other plants, be that houseplants, potted plants waiting to be transplanted outside, or even produce from the grocery store and farmer's market. You can prevent any and all pests by ensuring that your Garden does not have soil plants close by.
That said, houseplants love the Rise Garden and we know many of you use the garden to help your houseplants thrive.
Be sure to inspect the soil and leaves of your plants before moving them near your garden. Also, consider the source of your plant. High-quality stores and greenhouses are typically in the business of taking care of their plants and their communities. Always start with a reliable source first! This is especially important when starting from seed pods — pre-seeded growing pods that come ready to place directly into your hydroponic system — since introducing outside plant material nearby can put your entire harvest at risk.
Interacting with the outdoors
After a long day out shopping at the grocery store, or heading to your backyard to check on your non-hydroponic plants, you should stay clear of your Garden until you can wash your hands. Do not put anything like stones or freshly potted plants under your Garden's lights. Pests can travel far distances on your clothes or on your hands so be sure to keep your distance after being in nature as this could lead to pests in your garden. According to the USDA's Agricultural Research Service, common indoor plant pests like fungus gnats and aphids are among the most frequently transported insects, capable of hitchhiking indoors on clothing, fresh produce, and container plants.
It's also a good idea to keep your Garden far away from a door or a constantly open window. This area is constantly interacting with pests and is impossible to keep 100% pest free.
How Do You Keep Your Hydroponic Garden Clean?
Your app will tell you when it's time to deep clean your Garden. This ensures that you do not have a buildup of micronutrients — the trace minerals and compounds that plants absorb directly through water in a hydroponic system — in your water and that your water stays fresh and free of algae and bacteria. Research from Cornell University's Controlled Environment Agriculture program notes that maintaining clean reservoir conditions is one of the single most effective steps hydroponic growers can take to prevent pest and pathogen pressure. Another important cleaning habit is to remove any fallen leaves, trim yellowing branches, and to remove older plants that are past their prime. Pests are naturally drawn to drying plants and dead leaves, and studies show that decaying plant matter can attract fungus gnats within as little as 24 to 48 hours in warm indoor environments. Removing them will ensure you have a clean and tidy garden free of pests.
How Does Airflow Help Prevent Pests in an Indoor Garden?
One great prevention tip that will also keep your plants well-regulated is to add a small fan to your Garden so that it's hard for flying pests to land on your plants and reproduce. The constantly moving air will also strengthen the stems of your plants and provide a crunchier veggie. As a bonus, consistent airflow can reduce the surface humidity on leaves by up to 30%, making your indoor garden significantly less hospitable to spider mites and whiteflies, which thrive in still, humid conditions.
Frequently Asked Questions
Do hydroponic gardens get pests?
While hydroponic gardens like Rise Gardens are significantly less susceptible to many soil-borne pests since there is no soil for larvae to live in, indoor plants can still occasionally attract fungus gnats, aphids, spider mites, and whiteflies. The good news is that the controlled indoor environment makes it much easier to monitor your plants closely and address issues before they become serious infestations. Catching problems early, at the first sign of discoloration or unusual leaf damage, is the most effective approach.
How do you prevent pests in an indoor Rise Garden?
Prevention starts with good hygiene: rinse your reservoir regularly, remove dead plant material promptly, and avoid overwatering which creates humid conditions that attract fungus gnats. Keep your garden away from open windows and doors where outdoor pests can hitch a ride inside, and inspect new seedlings carefully before adding them to your system. Neem oil diluted in water is a highly effective, food-safe spray that can both prevent and treat common indoor plant pests without harming your harvest.
What are safe pest treatments for hydroponic vegetables?
For an edible hydroponic garden, you want to stick to treatments that are food-safe and won't leave harmful residue on your harvest. Neem oil, insecticidal soap, and diatomaceous earth are all effective organic options that are safe for use on edible plants. Introducing beneficial insects like ladybugs in a greenhouse setting or using sticky yellow traps for monitoring and catching flying insects are also excellent non-chemical strategies.
What pests are most common in indoor hydroponic gardens?
Fungus gnats are the most common pest in indoor hydroponic gardens, as their larvae thrive in moist growing media and can damage plant roots. Aphids and spider mites can also appear, particularly if plants are stressed by insufficient light, low humidity, or nutrient imbalances. Rise Gardens' closed system and LED-optimized environment reduces many of these stress factors, but regular plant inspection remains the best defense against any pest issue.
