Essential Materials

Gather the necessary supplies to get started on your rosemary propagation journey, ensuring you have everything ready for a smooth process.

• Plastic Bottles: Use 1-liter or 2-liter plastic bottles, which are ideal for sprouting beans due to their manageable size. Make sure each bottle is thoroughly cleaned and sanitized to avoid any bacterial contamination during the sprouting process.
• Mung Bean or Soybean Seeds: Choose dried mung bean or soybean seeds, which you can easily find at most grocery stores. Both types of beans sprout well and are nutrient-rich options for this process.
• Scissors: A good pair of scissors will be needed to cut the bottles, creating openings for easy access and drainage.
• Bowl or Tray: Place a bowl or tray under the bottles to catch excess water as it drains, keeping your workspace clean and dry.
• Clean Water: Use clean, filtered water for soaking and rinsing the beans to promote healthy sprout growth.

Step-by-Step Instructions

Follow these clear and simple steps to propagate, care for, and transplant rosemary, ensuring your plant thrives from the start.

Step 1: Get the Beans and Bottles Ready

Start by removing any labels from your plastic bottles, then wash them thoroughly with warm, soapy water, followed by a rinse with clean water. This step is crucial for keeping your sprouts free of contaminants. Using scissors, cut off the top of each bottle to create an open container that allows for proper air circulation.

Next, measure out your dried mung bean or soybean seeds. For 1-liter bottles, use around 1-2 tablespoons of seeds; for 2-liter bottles, opt for 2-3 tablespoons. Rinse the seeds well in cold water to eliminate any dust or impurities.

Step 2: Spread the Beans Evenly

Place the rinsed seeds in a container or bowl and cover them with enough water to allow soaking for 8-12 hours or overnight. This soak helps initiate the germination process.

Once the soaking period is complete, drain the seeds and spread them evenly across the base of each cut plastic bottle. Avoid overcrowding - aim for a single layer of seeds to give each sprout room to grow and thrive.

Step 3: Cover with Caps and Towels

After placing the seeds in the bottles, secure the tops you cut off earlier. You can use the bottle caps or cover the opening with plastic wrap held in place by a rubber band. Place the bottles in a dark, cool location, like a cupboard or pantry.

Drape a clean, damp kitchen towel over each bottle to maintain a humid and dark environment, which is ideal for sprouting.

Step 4: Water and Drain Regularly

Twice a day, gently remove the towels and turn each bottle upside down over the sink to drain out any excess water thoroughly, preventing mold and bacteria growth.

Return the bottles to their dark, cool spot, cover them again with the damp towels, and repeat the rinsing and draining routine twice daily.

Step 5: Harvest Your Fresh Sprouts

After 3-7 days, depending on temperature and the bean type, your sprouts will reach about 2-3 inches in length and take on a pale yellow color, signaling they’re ready for harvest.

To harvest, remove the caps or plastic wrap and place the sprouts in indirect sunlight for a few hours. This gentle exposure helps them develop a bit of chlorophyll, giving them a light green hue. When ready, use scissors to snip the sprouts just above the seed level, as the base may be a bit tough.

Finally, rinse the harvested sprouts under cold water to remove any remaining seed casings, making them fresh and ready to enjoy!

Helpful Tips

Keep these key pointers in mind to help your rosemary grow strong, healthy, and lush, no matter where you’re growing it.

Keep in Darkness

Keep your sprouting bottles in a dark location during the early stages, which helps the sprouts grow longer without producing much chlorophyll. As they near harvest time, you can briefly expose them to indirect sunlight to add a touch of green.

Ensure Good Drainage

Ensure thorough drainage after each rinse, as excess moisture can promote mold growth. If drainage is slow, try adding a few small holes in the bottle’s bottom to help water flow out more easily.

Maintain Ideal Temperature

A steady temperature of around 70°F (21°C) is ideal for sprouting. In cooler conditions, sprouts may grow more slowly, while warmer temperatures can accelerate the process.

Harvest with Cleanliness

At harvest, make sure to remove any remaining seed hulls. These hulls can add a slight bitterness and impact the flavor of your fresh sprouts.
