A rain barrel can be a great addition to your garden, providing a sustainable water source for your plants. By connecting your rain barrel to a timer and soaker hose, you can automate the watering process, ensuring your flowers get the hydration they need without any extra effort from you. Here’s a step-by-step guide on how to build your own rain barrel setup.

Tools and Supplies Needed

Tools:

1. Drill with various drill bits

2. Hole saw (for cutting larger holes)

3. Jigsaw or handsaw (for cutting overflow and hose outlets)

4. Adjustable wrench

5. Pipe wrench

6. Utility knife

7. Screwdriver

8. Level

9. Tape measure

10. Pencil

Supplies:

1. Barrel: A food-grade plastic barrel (55-gallon capacity is typical). Be sure to get a dark color for algae prevention.

2. Spigot Kit: Includes spigot, washers, and nuts (some barrels on Amazon come with the spigot)

3. Overflow Kit: Includes hose or pipe, washers, and nuts (depending on type of diverter and how system is set up, overflow kit may not be needed).

4. Mesh Screen: To cover the top of the barrel and prevent debris and insects

5. Downspout Diverter: To channel water from the gutter into the barrel

6. Soaker Hose: To distribute water to your flower garden (may need landscape staples to secure in placeO

7. Hose Timer: Connects to the spigot for automated watering

8. Thread Seal Tape: To ensure a watertight seal on threaded connections

9. Cinder Blocks or Stand: To elevate the barrel for better water flow

10. Silicone Sealant: To seal any gaps around fittings

Step-by-Step Instructions

Prepare the Barrel

1. Clean the Barrel: Ensure your barrel is clean and free from any contaminants.

2. Cut the Inlet Hole: Using a hole saw, cut a hole on the top of the barrel for the downspout diverter. The size will depend on your diverter’s specifications.

Install the Spigot

1. Drill the Spigot Hole: About 2-3 inches from the bottom of the barrel, drill a hole for the spigot.

2. Attach the Spigot Insert the spigot into the hole, using washers and nuts to secure it. Apply thread seal tape to the spigot threads before tightening to ensure a watertight seal.

3. Seal the Spigot: Apply silicone sealant around the spigot hole to prevent leaks.

Set Up Overflow System

1. Drill the Overflow Hole: Near the top of the barrel, drill a hole for the overflow pipe or hose.

2. Attach the Overflow Fitting: Insert the overflow fitting into the hole, securing it with washers and nuts. Connect the overflow hose or pipe and direct it away from your house’s foundation.

3. Seal the Overflow: Apply silicone sealant around the overflow hole to ensure no leaks.

Install the Mesh Screen

1. Cut the Screen: Cut a piece of mesh screen to fit over the top opening of the down spout.

2. Secure the Screen: Attach the screen using a clamp or screws to keep it in place and prevent debris and insects from entering the barrel.

Connect the Downspout Diverter

1. Install the Diverter: Follow the manufacturer’s instructions to install the downspout diverter. This usually involves cutting the downspout and attaching the diverter, which will direct water into your barrel.

2. Connect the Diverter to the Barrel: Attach the hose from the diverter to the inlet hole on the top of the barrel.

Set Up the Soaker Hose and Timer

1. Elevate the Barrel: Place the barrel on cinder blocks or a sturdy stand to increase water pressure.

2. Attach the Timer: Connect the hose timer to the spigot on your barrel.

3. Connect the Soaker Hose: Attach the soaker hose to the timer. Lay the soaker hose throughout your flower garden, ensuring it reaches all the plants you want to water.

4. Set the Timer: Program the hose timer according to your garden’s watering needs. Remember that watering shortly after sunset causes water to stand for longer period of time increasing chance of fungus; water in the middle of the day and the water gets evaporated more quickly reducing effectiveness of the rain barrel.

Tips for Optimal Use

1. Regular Maintenance: Check the mesh screen and filters regularly to ensure they are free of debris.

2. Seasonal Care: Drain and store your rain barrel during winter to prevent freezing and cracking.

3. Monitor Water Levels: Keep an eye on water levels, especially during dry spells, to ensure your garden gets enough water.

4. Adjust the Timer: Adjust the watering schedule on the timer based on seasonal changes and weather conditions.

Conclusion

Building your own rain barrel setup to water your flower garden is a rewarding project that can save water and promote healthier plants. With the right tools and supplies, you can create an efficient system that provides consistent watering, ensuring your garden thrives. Enjoy the benefits of sustainable gardening with your new rain barrel!
