Best Self Watering Planters
I’ve been a gardener for years, and I’ll say this plainly: self watering planters changed the way I grow things. They keep soil evenly moist, reduce daily watering chores, and help plants thrive in hot weather or busy schedules. In this guide I’ll walk you through the best self watering planters available, what to look for, who they’re best for, and how to get the most from them. I’ll share honest pros and cons and my personal favorites so you can pick the right one for your home or garden.
Why choose a self watering planter
Self watering planters store water in a reservoir below the growing medium and feed it to plant roots by capillary action or a wicking system. The benefits are immediate and practical:
- Less frequent watering — ideal for busy gardeners or vacationers
- More consistent moisture — fewer stress cycles for plants
- Better root health — roots grow deeper toward the reservoir
- Water savings — less evaporation and runoff
- Great for containers, balconies, and vegetable gardening
What to look for in the best self watering planter
Not all self watering planters are created equal. When I shop, these features are non-negotiable:
- Water level indicator — saves guesswork and prevents overfilling
- Overflow/drainage — protects roots in heavy rain
- Durable materials — UV-resistant plastic, quality ceramics, or sturdy composites
- Removable reservoir or easy cleaning access — prevents algae and salt buildup
- Size and shape that suit your plants — large for tomatoes, shallow for herbs
Types of self watering systems
- Reservoir planters with fill tubes — most common and user-friendly
- Wicking planters — simple fabric or rope wicks draw moisture up
- Sub-irrigation planters (SIP) — trays that flood then drain slowly to roots
- DIY systems — modified buckets, recycled containers, or a double-pot method
Top picks and who they’re best for
Over the years I’ve tested many planters. Here are those I keep recommending to friends and readers.
- Lechuza planters — Elegant, high-quality, and with reliable water level indicators. Perfect for indoor houseplants and patio containers when you want style without fuss. I use a Lechuza Cube for my fiddle leaf fig and it keeps the soil evenly moist for weeks.
- EarthBox — Made for vegetables and heavy feeders. The reservoir and planting inserts are designed to maximize root zone moisture — excellent for tomatoes, peppers, and salad greens. This is my go-to for summer veggie pots.
- Elho Green Basics — Good-looking, affordable, and available in many sizes. They often include a practical reservoir and work well on balconies or entryway displays.
- Bloem or similar budget brands — For beginners or temporary use, many budget self-watering pots do a fine job. Look for ones with clear indicators and good reviews.
- DIY double-pot or bucket system — For gardeners who like building, a five-gallon bucket transformed into a reservoir planter is economical and effective. I built one last season for a climbing bean with great results.
Plants that thrive in self watering planters
These planters are versatile, but some plants love them more than others:
- Herbs (basil, parsley, cilantro) — stay tender and productive
- Leafy greens (lettuce, spinach) — consistent moisture means continuous harvests
- Tomatoes and peppers — especially when in well-ventilated, larger containers
- Houseplants (pothos, philodendron, peace lily) — reduced watering upkeep
Be cautious with succulents and cacti; they prefer drier conditions and can suffer if the reservoir keeps the soil too wet.
Maintenance tips for long-lasting performance
Treat your self watering planter like any garden tool — some simple care keeps it working well:
- Rinse the reservoir and refill tube between seasons to prevent algae
- Use a well-aerated potting mix with some perlite or coco coir to maintain capillary action
- Check the water indicator weekly and top up as needed — fewer surprises this way
- Flush salts by occasionally watering from the top until excess drains out
- Move inside or protect from freeze in winter to avoid cracking
I always say: a good self watering planter is like a reliable friend — it keeps things steady so you can focus on the fun parts of gardening. I’ve had mine rescue tired herbs through heatwaves and busy weekends alike.
Common mistakes and how to avoid them
Even with self watering planters, new gardeners make avoidable errors. Here’s what I’ve learned the hard way:
- Using garden soil — always use light potting mix
- Ignoring overflow — make sure your planter has a safe drainage path
- Overcrowding plants — roots need access to the reservoir and air
- Forgetting to clean — algae and mineral buildup reduce effectiveness
Final recommendation
If you want one recommendation to start, choose a planter with a clear water level indicator, a reliable overflow, and a size appropriate for your plants. For indoor style and peace of mind, Lechuza is a premium choice. For serious vegetable growing in containers, EarthBox delivers consistent yields. For budget-conscious or experimental gardeners, a DIY reservoir planter gives excellent performance at low cost.
Personally, I keep a mix: an elegant Lechuza for indoor ornamentals, EarthBox for my tomatoes, and a DIY bucket planter for seasonal trials. That combo covers everything from low-maintenance houseplants to heavy-feeding summer crops and lets me enjoy gardening without becoming a full-time waterer.
Happy planting — once you try a good self watering planter, you’ll wonder how you ever managed without one.
