What Do You Need to Grow Watercress Indoors?

Ready to embark on your watercress-growing adventure? To grow successfully and healthily your watercress plants indoors, a few key elements are needed. No need to worry, we’ll guide you through everything you’ll need to ensure the best growing conditions for your watercress:

  • Watercress tends to thrive in moist and fertile garden soil, which is rich in organic matter. A well-draining soil mix is thus the ideal choice for retaining a level of moisture that is ideal to promote healthy plant growth;
  • Consider using soilless potting mixes or hydroponic systems, which offer precise control over moisture levels and nutrient distribution;
  • Choose containers, or seeds trays that are spacious enough to accommodate the growth of watercress, allowing the roots to spread freely. A larger container is recommended to provide ample room for its expansion;
  • Watercress requires a consistently moist environment to thrive. Ensure that the planting area and/or containers are filled with fresh water or positioned near a water source so that its roots can be sufficiently nourished;
  • Consider supplementing the water with a complete soluble fertilizer to provide essential nutrients for healthy growth.

How to plant Watercress indoors?

Are you eager to start growing watercress indoors? Nothing simpler! By following this step-by-step guide, you’ll be able to kickstart your indoor watercress garden. Whether you’re using traditional methods or Gardyn’s innovative solutions, here are all the information you need to successfully plant watercress in the comfort of your own home:

Step 1: Prepare Your Container

Pick a container, or a seed tray, that allows for proper drainage and has enough space for the watercress to spread its roots. Then, fill it with the chosen potting mix, leaving about an inch of space at the top. Feel free to mix compost, perlite, or vermiculite with the soil mix, as these elements will help retain water. If you’re using the Gardyn Home Kit 3.0, insert the specially designed yCubes into the designated pods. These yCubes provide the perfect environment for watercress to grow at home.

Step 2: Find the Perfect Location

Find a suitable location with sufficient natural light to place the container. Watercress thrives with four to six hours of sunlight daily, but make sure to protect your plants from direct sunlight during the hottest parts of the day.

Step 3: Plant Your Watercress Seed

First of all, make sure to keep the planting area moist. Then, if you want to grow watercress from seeds, sow them directly into containers or seed trays, ensuring a spacing of approximately one inch between each seed, to allow for proper growth. Then, gently press them into the soil or yCubes, ensuring they are firmly in place. If you want to plant cuttings or stems, dig them gently into the soil or yCubes, and cover them up with potting mix. Water the container thoroughly, making sure the soil or yCubes are moist but not waterlogged in order to avoid waterlogging.

How to care for your Watercress?

Watercress is a relatively low-maintenance plant, and with the right care, you can enjoy a bountiful harvest of fresh, peppery leaves. Consider using Gardyn innovative solutions to make it easier for you to care for your watercress plants and optimize their growth. Here are a few additional tips for caring and growing watercress plants:

  • Keep the soil or growing medium consistently moist. Watercress thrives under wet conditions, so it’s important to provide an adequate water supply;
  • Ensure the water level is sufficient to cover the roots. Consider using a container with a water reservoir;
  • Monitor the water level regularly and add water as needed to prevent the soil from drying out. Watercress plants may require watering several times a day to keep the soil consistently moist;
  • Use a soluble fertilizer specifically formulated for watercress or leafy greens. Apply it directly to the water, allowing the plant to absorb the nutrients through its roots;
  • Regularly prune your watercress plants to promote bushier growth and prevent them from becoming leggy. Remove any yellowing or damaged leaves to maintain the overall health of the plant;
  • Keep a close eye on your watercress plants to detect any sign of garden pests (aphids, slugs, snails, spider mites, caterpillars, etc.). Early detection allows for timely intervention and prevents major infestations. If you find any, opt for organic and environmentally friendly pest control methods.

Harvesting and Using Your Watercress?

Harvesting And Using Your Cucumber

Once your watercress has matured, it’s time to harvest and enjoy its flavorful leaves. Whether you plan to use it for cooking, garnishing, or juicing, here’s what you need to know so you can get a jumpstart to appreciating your latest addition:

How and When to Properly Harvest Your Watercress?

Watercress plants can be harvested once they reach a mature size, typically around 6 to 8 weeks after planting. Use a pair of clean gardening shears or sharp scissors to cut only a few inches off the watercress leaves, just above the waterline or where the stem meets the main plant.

For a continuous supply, harvest the outer leaves while leaving the inner ones to continue growing. This method allows for regrowth and a steady harvest.

Making the Most Out of Your Watercress

Watercress is a versatile herb that adds a peppery punch to various dishes. Use it in salads, sandwiches, soups, or as a flavorful garnish.

  • Blend watercress into smoothies or juices to incorporate its fresh taste and health benefits into your diet.
  • Try making a watercress pesto by combining fresh watercress leaves, garlic, pine nuts, Parmesan cheese, and olive oil in a food processor. Use this flavorful sauce on pasta, sandwiches, or as a dip.
  • Experiment with watercress in stir-fries, omelets, or as a topping for pizzas for an added burst of flavor.
  • Watercress can also be used as a decorative element in culinary presentations, adding visual appeal to your dishes.
