Keep your window displays lush and vibrant with our self-watering window box systems, curated by Hooks & Lattice for healthier plants and easier maintenance. We’ve selected a range of window box accessories designed to work with our custom-fit water reservoirs, transforming traditional containers into low-maintenance, self-sustaining planters. Browse our collection today.
When you choose a self-watering window box, simply select the option to add a water reservoir during checkout. We’ll include the correct number and length of reservoirs to pair perfectly with your chosen box. Don’t worry—a reservoir doesn’t have to span the full box length. Our specially engineered design efficiently waters the soil within a 6–8" radius, keeping nearby plant roots hydrated and thriving.
Creating a self-watering system in a window box or planter is simple and takes just minutes:
1. Add a layer of small pebbles at the bottom of your window box to support drainage.
2. If your box has drainage holes, lay down a piece of filter fabric to keep soil in place.
3. Place the reservoir on top of the gravel layer and insert the fill tube.
4. Add high-quality potting soil, ensuring the fill tube remains above the soil surface.
5. Plant your flowers and top-water initially to help roots reach the moisture source.
6. Fill the reservoir through the tube. Once established, plant roots will self-regulate water intake, drawing exactly what they need, when they need it.

There’s a special kind of satisfaction in watching a window display turn into a cascading, colorful tapestry. Since self-watering window boxes deliver moisture right where the roots need it, your plant choices are virtually limitless.
These systems are perfect for thirsty, high-impact trailing flowers – think vibrant petunias, wispy lobelia, or delicate bacopa. They’re equally great for seasonal color like geraniums, pansies, or moody impatiens. For those who want to grow their own herbs, mint, basil, and thyme absolutely flourish with steady, reliable hydration.
These are the kinds of professional-grade, lush arrangements that practically tend to themselves – a massive win for busy schedules. Want that same charm but need to stay green year-round without the upkeep? Take a look at our line of artificial plants instead.
Creating a knockout outdoor presentation really comes down to getting the hardware right. Whether outfitting a traditional home or just trying to dress up a small balcony, Hooks & Lattice has everything you need to make it happen.
You can pair our reservoirs with a wide range of window boxes compatible with these systems, and don’t forget to add liners to protect your investment. We also carry brackets and bolts for your self-watering window boxes to make installation easier. For city living with limited space, see our railing planters – they’re an elegant adornment for decks.

A water reservoir sits within the planting area and delivers moisture upward through the soil as plants need it, so roots self-regulate intake and stay consistently hydrated. See our installation guides for full setup instructions.
Our water reservoirs are designed to work with a wide range of our window box styles, and we'll include the correct number and length at checkout when you select the self-watering option. Browse our full selection of compatible window boxes to find your match.
No. Each reservoir delivers moisture to the soil within a 6–8" radius, so multiple smaller units can work together across a longer box. This design ensures even coverage without requiring a single full-length reservoir.
Refill frequency varies by plant type, box size, and weather conditions, but most gardeners find every one to two weeks sufficient once plants are established.
Trailing flowers like petunias, lobelia, and bacopa thrive with consistent moisture, as do herbs such as mint, basil, and thyme — making these systems ideal for ornamental and edible displays alike. For year-round color with no replanting, our artificial flowering plants also work beautifully across our window box styles.
We recommend adding a liner to keep soil in place and support healthy drainage alongside the reservoir. Brackets and bolts are also available to complete your installation securely.
