Hand Watering – Watering the Old-School Way
If you're starting as a gardener and just have one or two raised beds, you might find hand-watering doable. Some folks even enjoy this slow, therapeutic process. You can also catch pest or disease issues early by being up close and personal with your plants.
Of course, if you depend solely on hand-watering, rainy days could be a problem, especially in the scorching summer months.
If you do choose hand-watering, I recommend using the Hoselink Retractable Garden Hose for simplicity and a cleaner garden area.
Perks of Hand Watering:
- You can control the watering amount
- Get up close with your plants for early problem detection
- Water the root zone to minimize evaporation and reduce fungal infections
- Some find it relaxing
Drawbacks of Hand Watering:
- Over-watering is common and can harm your plants
- You have to water daily, which can be a pain
- Lugging out the hose daily isn't fun (unless you use the Hoselink retractable garden reel)
Overhead Watering – The Garden Shower
Lots of gardeners employ overhead watering using a sprinkler for their gardens. While this might work for large in-ground gardens, it's less practical for raised bed gardens.
The main problem is that you end up watering the pathways rather than just the beds. If your pathways are made of earth, you'll be watering grass and weeds, leading to more maintenance. If they're gravel, you're wasting water.
Overhead watering might still be an option for you.
Watering Perks:
- Can be set on a timer to reduce daily hassle
- Helps keep plants cool in the heat
- Easy setup
Drawbacks of Overhead Watering:
- Wastes water through evaporation (which can be expensive)
- Can worsen fungal infections, especially if you live in a humid area
- Wet the walkways, making weeds flourish
- Uneven water distribution
Soaker Hoses – Slow and Steady
Soaker hoses are a popular way to water raised beds. They're affordable, simple to set up, and seep water along the entire hose, ensuring minimal evaporation. No water splashes on the plants, which can alleviate pressure from fungal diseases.
However, longevity can be a concern with soaker hoses. I found that they become less effective over time, requiring replacement in 2-3 years.
Soaker Hose Pros:
- Inexpensive
- Easy setup
- You can buy hoses in different lengths
Soaker Hose Cons:
- Clogging over time
- Can be expensive if you have multiple beds
Drip Lines
I switched all of my garden to drip lines a few years ago, including in my dozen or so raised beds. Drip lines are small tubes with emitters scattered along the tube. Some tubes emit water at 6” intervals, while others are spaced at 12”.
Drip lines work well for both large in-ground gardens and raised bed irrigation. They're durable, long-lasting, and offer customization for your garden area. I found problems with distributing water equally in my large 3000-square-foot garden, as the further from the water source, the less evenly the water was distributed. This led to uneven growth among my plants.
Drip Line Advantages:
- Economical for the ground covered
- Easy to repair
- Easily customized
- Many options like drip lines, misters, single plant watering, on/off valves, etc.
Drip Line Disadvantages:
- Uneven water distribution in large spaces
- Easily cut by cultivation tools
- Can clog with soil and debris
Drip Tape – Tiny Powerhouses
Drip tape is an excellent option for watering raised beds. Similar to drip lines, the tape is made up of a 3/4” flat tubing with emitters at certain intervals. Unlike drip lines, the emitters on drip tape release water evenly throughout the system, ensuring consistent irrigation in your multiple raised beds.
Initially, installing drip tape could seem complicated, but if you're the handy type, it's something you can figure out. Keep in mind that setting it up in several raised beds can be labor-intensive and may cost more than the other options. Once installed, though, it improves water distribution to your plant roots.
Drip Tape Perks:
- Even watering – essential for multi-raised bed gardens
- Easy to work with once installed
- Customizable to your garden layout
Drip Tape Concerns:
- Complicated setup for the average person (feasible if you're handy)
- Can be expensive
- Numerous components to buy: pressure regulator, tubing, elbows, T's, connectors, and caps
- Longevity varies but is said to only last a few years
Garden Grid – Behold the Future of Raised Bed Irrigation
After I had set up almost all of my raised beds with drip tape in the spring of 2022, Garden in Minutes contacted me, asking me to test out their Garden Grid irrigation system. Eager to give it a try, I accepted their offer – and I couldn't be happier with the results.
The Garden Grid offers even water distribution, is simple to install, and can be removed easily when it's time for garden renovation. Its pre-set layout also works as a ready-made plant spacing system, with each square being 11” apart.
Garden Grid Opening Argument:
- Water distribution is consistent within the bed
- Easy to assemble
- Simple to remove during renovation
- Squares are 11” apart, creating a ready-made plant spacing system
- Long-lasting: prototypes have been in place since 2013
Garden Grid Closing Argument:
- If placed within a system with other irrigation (like drip tape or drip lines), it provides more moisture than the others, leaving the beds watered differently (thus, my long-term goal is to switch all of my beds to the Garden Grid)
