Step-by-Step Guide
### Step 1: Collect and Clean Plastic Bottles
What: Gather your plastic bottles and clean them to remove any residue.
How: Rinse all the bottles with warm, soapy water. Be sure to scrub the insides thoroughly to eliminate any contaminants or residue from earlier contents. After cleaning, allow them to dry completely, as this will prevent mold growth in your plants.
Tips: You can also remove labels to make your garden wall look more aesthetic. If the adhesive doesn’t come off easily, soaking in hot water can help loosen it.
Safety: Be cautious while handling any sharp objects like the scissors or utility knife. Wear gloves when cleaning the bottles, especially if there's any sticky residue.
### Step 2: Prepare Your Bottles
What: Cut your bottles to make openings for your plants.
How: Using your scissors or a utility knife, carefully cut a rectangular opening on the side of each bottle. Leave some space at the bottom for planting. Generally, a 3-4 inch opening works well.
Tips: Consider how the bottles will be positioned on the wall. You might want the openings to face outward for optimal sunlight exposure.
Safety: Always keep your hands away from the cutting edge and work slowly to avoid accidental slips that could lead to cuts.
### Step 3: Create Drainage Holes
What: Drill holes at the bottom of each bottle.
How: Using the drill and an appropriate drill bit, make several small holes at the bottom of each bottle. This will ensure proper drainage of excess water and prevent root rot.
Tips: Space the holes evenly and test with water after drilling to ensure it flows correctly.
Safety: Make sure to wear safety goggles to protect your eyes from any debris generated during drilling.
### Step 4: Add a Liner
What: Line the inside of the bottles to retain soil.
How: Cut pieces of landscape fabric or old T-shirts to fit inside each bottle, leaving some to hang over the edges. This will help hold the soil in place while allowing excess water to drain.
Tips: If using a T-shirt, consider a dark color to blend well with the soil and prevent light from entering, which can lead to algae growth.
Safety: Ensure there are no sharp bits of plastic around after cutting to avoid injury during handling.
### Step 5: Fill the Bottles with Soil
What: Prepare the soil mixture for planting.
How: Mix potting soil with compost in a bucket at a ratio of about 70% soil to 30% compost for added nutrients. Fill each bottle almost to the top but leave some space for watering.
Tips: If you're using larger bottles, you may want to add a layer of small rocks or gravel at the bottom to enhance drainage.
Safety: Make sure the soil is moist, but not wet, to prevent dust. Use a mask if you're sensitive to soil dust.
### Step 6: Plant Your Herbs
What: Plant your chosen herbs within the bottles.
How: If using seedlings, make a small hole in the soil and place the roots in the bottle, covering them lightly with soil. For seeds, scatter a few seeds on top of the soil and press them down gently.
Tips: Research the sunlight and water needs of your chosen herbs beforehand. Basil and mint love sunlight, while cilantro prefers partial shade.
Safety: Keep your workspace organized to avoid losing small seeds or seedlings.
### Step 7: Secure the Bottles for Vertical Gardening
What: Mount your bottles onto the wall.
How: Use your measuring tape to decide on the spacing of your bottles. Attach hooks or brackets to the wall, ensuring they can support the weight of filled bottles. Hang each bottle securely.
Tips: You might want to create a staggered arrangement, so each bottle receives adequate sunlight.
Safety: If you're using a ladder to reach higher areas, ensure it's stable and get someone to assist you.
### Step 8: Water and Maintain Your Garden
What: Establish a watering routine and general maintenance.
How: Use a watering can or spray bottle to water your plants by checking the soil moisture level weekly. Ensure that the soil is damp but not waterlogged.
Tips: An easier way to water could be to use a drip irrigation system if you have more extensive arrangements. Monitor leaves for signs of drying or wilting as a sign to adjust your watering schedule.
Safety: Be mindful of where you step, especially if you're working in an area with wobbly bottles or small equipment.
### Step 9: Monitor Growth and Conditions
What: Observe your herbs for well-being and growth.
How: Check the sunlight exposure daily and rotate the bottles if they're leaning toward one direction. Look for pests or diseases and act quickly to remove any unhealthy foliage.
Tips: Keep a notebook tracking each herb's growth patterns and needs to improve your gardening skills over time. Adjust watering based on the changing seasons.
Safety: Always sanitize your tools after use to prevent disease spread among your plants.
### Step 10: Harvest and Enjoy!
What: Begin using your herbs in your culinary adventures.
How: Regularly harvest the leaves once the plants are sufficiently grown, leaving a few leaves behind to encourage further growth.
Tips: Use clean scissors to avoid bacteria transfer when cutting your herbs. Regular pruning encourages bushier growth.
Safety: Be careful when handling sharp tools like scissors, especially if your hands are in soil.

Troubleshooting
1. Problem: Plants are wilting or yellowing. Fix: This may indicate overwatering or underwatering. Adjust your watering schedule, allowing the soil to dry out slightly between waterings.
2. Problem: Pests like aphids appear on herbs. Fix: Spray the affected plants with a mixture of water and mild soap. Manual removal under a stream of water also works effectively.
3. Problem: Container leaks. Fix: Ensure your drainage holes are not too large; you might want to add a piece of fabric underneath to prevent soil loss while still allowing drainage.
4. Problem: Herbs are growing unevenly. Fix: Rotate your bottles regularly to ensure all sides receive adequate sunlight. Consider rearranging plants to provide shade for those that need it.
5. Problem: Mold growth in soil. Fix: This usually indicates overwatering. Allow the soil to dry out before the next watering, and ensure proper air circulation around your plants.
