Newspaper Pot Makers for Transplants: Zero Waste Gardening

Why This Method Works

What You'll Need

• Container: Newspaper
  • Type: Seek out plain black and white newspaper. Avoid glossy inserts or colored sections, as these often contain inks that aren’t vegetable-based and can leach undesirable chemicals into your soil. I usually grab a local weekly paper or the inside sections of a larger daily.
  • Preparation: Tear or cut strips of newspaper approximately 5 inches wide and 10-12 inches long. The exact dimensions will depend on the size of your pot maker. The goal is to have enough to wrap around the cylindrical part of the maker with some overlap and enough excess to fold under for the base.
• Growing System: Seed Starting
  • Seed Starting Mix: A high-quality, fine-textured seed starting mix is crucial. It should be sterile, well-draining, and have a light, fluffy consistency. I avoid using regular garden soil for seedlings as it can be too heavy, harbor weed seeds, and contain pathogens. Look for mixes specifically formulated for seed starting.
  • Trays or Waterproof Liners: Since newspaper pots are biodegradable and will get wet, you'll need a waterproof tray to hold them. Reused plastic takeout containers, old baking sheets, or dedicated seed starting trays (without drainage holes, or with a solid tray underneath) work perfectly. This prevents water from dripping onto your shelves or windowsill.
• Other Materials:
  • Newspaper Pot Maker Tool: You can buy these online, often made of wood. They consist of a cylindrical body and a plunger designed to create the pot's base. Mine is a simple wooden one, and it's built to last.
  • Seeds: Of course! Choose varieties suited for your growing conditions and space. For apartment dwellers, think compact varieties of herbs, salad greens, bush beans, or dwarf tomatoes.
  • Watering Can/Spray Bottle: A small watering can with a fine rose or a spray bottle is ideal for gently watering seedlings without dislodging them or washing away seeds.
  • Labels: Don't underestimate the importance of labeling! Craft sticks, plastic tags, or even strips of newspaper work. I use a permanent marker to avoid fading.
  • Grow Lights (Optional but Recommended): Especially in apartments with limited natural light, grow lights make a huge difference in preventing leggy seedlings. A simple shop light with fluorescent tubes or a dedicated LED grow light will suffice for a small setup.
  • Small Trowel or Dibber: Handy for filling pots and making holes for seeds.

Once you’ve got your pots ready to fill, remember that adequate soil volume is key for healthy root development. Check out our soil volume calculator for precise measurements to ensure you're using the right amount of mix for the number of pots you're making!

Step-by-Step Guide

Days 1-3: Setup and Sowing

1. Make Your Pots: Take a strip of newspaper. Wrap it tightly around the cylindrical body of your pot maker, leaving about an inch or so of overlap at the open end and about 2-3 inches hanging over the bottom. Once wrapped, use the plunger part of the maker to fold and press the overhang firmly into the base, creating a sturdy bottom. Slide the finished pot off the maker. With practice, you’ll be making dozens in no time! I can usually churn out about 20-30 in ten minutes.
2. Fill and Sow: Arrange your newly made newspaper pots snugly in your waterproof trays. Fill each pot almost to the top with your moistened seed starting mix. Gently tamp down the mix to remove large air pockets. Follow the seed packet instructions for planting depth – generally, sow seeds at a depth two to three times their width. For tiny seeds, just sprinkle them on the surface and lightly cover with a thin layer of mix.
3. Water Gently: Mist the pots thoroughly with a spray bottle or use a watering can with a very fine rose. The goal is to moisten the soil without disturbing the seeds.
4. Provide Warmth: Many seeds benefit from warmth to germinate. If you have a seedling heat mat, this is the time to use it. Place your trays on the mat. Ideal temperatures for most seeds are between 70-80°F (21-27°C).
5. Label and Cover: Label each pot immediately with the plant type and sowing date. Cover the trays with a clear humidity dome or plastic wrap to maintain moisture.

Days 4-7: Initial Growth and Light

6. Monitor for Germination: Check your pots daily. As soon as you see the first sprouts emerge, remove the humidity dome or plastic wrap.
7. Provide Light: This is critical! Move your sprouted seedlings immediately under grow lights or to a very bright windowsill. If using grow lights, position them just a few inches above the seedlings (2-4 inches is a good starting point for most LEDs, adjust for fluorescents). If they don't get enough light, they will become "leggy" – tall, spindly, and weak. I've learned this the hard way too many times!
8. Maintain Moisture: Keep the seed starting mix consistently moist, but not waterlogged. Water from the bottom by pouring water into the tray and letting the pots absorb it, or continue with gentle misting.

Days 8-21: Thinning and Strengthening

9. Thin Seedlings: Once seedlings develop their first "true leaves" (the leaves that appear after the initial round, or "cotyledons"), thin them. Choose the strongest, stockiest seedling in each pot and carefully snip off the others at the soil line with small scissors. This gives the chosen seedling room to thrive.
10. Lower Lights (if applicable): As seedlings grow, raise your grow lights to maintain the ideal distance.
11. "Hardening Off" Introduction (Very Limited): If the weather permits and your space allows for a tiny outdoor venture, start thinking about introducing very short, supervised outdoor stints. For apartment dwellers, this might mean opening a window near the seedlings for an hour or two on a mild, cloudy day, or moving them to a sheltered balcony for a short period. This builds resilience.

Days 22-30+: Continued Growth and Transplant Preparation

12. Fertilize Lightly: Around the 3-4 week mark, your seedlings will have used up most of the nutrients in the seed starting mix. Begin feeding them with a very diluted liquid fertilizer (quarter strength).
13. Continue Hardening Off: Gradually increase the time seedlings spend outdoors, exposing them to filtered sunlight, gentle breezes, and cooler temperatures. This is vital to prevent transplant shock. Start with an hour in a shaded spot, then gradually increase time and light exposure over 7-10 days. For apartment growers, this might be the most challenging part, but even a few degrees cooler and some air movement can make a difference.
14. Prepare for Transplant: Once your seedlings have 2-3 sets of true leaves and have been properly hardened off, they're ready for their final home. Ensure the soil in their new container or garden bed is prepared and well-watered.
15. Transplant: This is the easy part! Dig a hole slightly larger than your newspaper pot. Place the entire newspaper pot into the hole, ensuring the top edge of the pot is level with or just below the soil surface. Backfill gently around the pot and water thoroughly. The newspaper will quickly begin to break down, allowing the roots freedom.

Common Mistakes to Avoid

1. Using the Wrong Newspaper: As mentioned, glossy or colored sections often contain heavy metals or chemical inks not safe for consumption, especially if you're growing edibles.
   • Solution: Stick to plain black and white newspaper, preferably from smaller, local publications that tend to use vegetable-based inks.
2. Making Flabby Pots: If the newspaper isn't wrapped tightly or the base isn't firmly pressed, your pots can lose their shape once wet, leading to soil spillage and instability.
   • Solution: Practice makes perfect! Ensure you wrap the newspaper tightly around the pot maker and apply firm, even pressure when forming the base. A little overlap at the top also helps them retain shape.
3. Overwatering in the Early Stages: While newspaper pots allow for good drainage, it's still possible to overwater, especially if your seed starting mix is too dense or your trays don't allow for proper air circulation.
   • Solution: Always ensure your seed starting mix is well-draining. Water from the bottom when possible, allowing the pots to wick up what they need. Lift a pot to gauge its weight – heavy means moist, light means dry.
4. Insufficient Light After Germination: This is a classic rookie mistake and one I struggled with early on. Seedlings quickly become leggy and weak if they don't get enough immediate, bright light.
   • Solution: As soon as sprouts appear, provide strong light. A dedicated grow light is often the best solution for urban gardeners, as most windowsills simply don't offer enough intensity. Keep the lights very close to the seedlings.

Pro Tips for Maximum Success

1. The "Snug Fit" Method for Trays: When arranging your filled newspaper pots in a tray, try to fit them snugly together. The slight pressure from neighboring pots helps them maintain their shape and prevents them from collapsing or leaning, especially after watering. This also helps keep moisture consistent across the tray.
2. Bottom Watering with a Twist: Instead of just refilling the tray, every few days I'll let the trays sit in about an inch of water for 15-20 minutes, then drain any excess. This encourages roots to grow downwards in search of water and helps prevent damping-off disease by keeping the surface of the soil drier.
3. The Fan Trick for Strong Stems: Once your seedlings have their true leaves, run a small fan on a low setting for a few hours a day, positioned so it creates a gentle breeze over your plants. This mimics natural wind, helping to build stronger, stockier stems, which are less prone to breaking during transplanting. It’s a simple setup that makes a surprising difference!
4. Timing is Everything: Don't try to transplant too early or too late. Too early, and they're fragile; too late, and they can become root-bound in their newspaper pots (though less of an issue than plastic). Observe your seedlings – strong stems, several sets of true leaves, and an established root system (you might see some roots peeking through the newspaper) are indicators they're ready. Also, ensure your outdoor conditions (temperature, frost risk) are appropriate for the plant.
