HomeGrowingGrow Microgreens on Your Windowsill: Fresh Greens at Your Fingertips

It is easy to grow microgreens on your windowsill. Simply use a tray with suitable drainage, fill it with soil or a growing medium, and sprinkle the seeds evenly on top. Place the tray near a window where it can receive adequate sunlight, and water regularly.

Choosing the Right Seeds

Choosing the right seeds for your microgreens is like picking out the perfect gemstone–the more effort you put in, the greater your rewards will be!

When selecting seeds for your microgreen garden, it is important to consider a variety of factors such as size and shape, color, flavor and texture. It is also important to choose varieties that are suited to different harvesting methods.

Some microgreens can be harvested within two weeks of sowing whereas others may require up to six weeks before they are ready for cutting.

When selecting seeds for your microgreen garden, make sure you look carefully at the seed packet labels and research any unfamiliar varieties before purchasing them. This will help ensure that you get the most out of each variety by understanding how best to grow it.

You should also take into account the cost and availability of various types of seeds when making your selection as this will affect how much time and money you have available for growing.

Another factor to consider when choosing seeds is their nutritional content. Different varieties provide varying levels of vitamins A, C, E, K and other essential nutrients which can provide health benefits when consumed fresh or cooked in recipes.

Many people opt for organic varieties due to their increased nutrient content but bear in mind that these may require more attention during growth than conventional varieties so factor this into your decision-making process too.

Finally, it’s worth taking some time to experiment with different seed selections so that you get a better idea of what works best in your particular environment – both indoors on a windowsill or outdoors in a larger space. Be sure to keep notes on each variety’s performance so you know what adjustments need making next season!

Preparing the Tray and Soil

After carefully selecting the best seeds for your microgreen garden, it’s now time to prepare the tray and soil for sowing. To get started on this next step in growing microgreens indoors, you’ll need a shallow container with drainage holes and some nutrient-rich soil.

Here are a few tips to consider when prepping the tray and soil:

  • Soil Nutrition: When choosing potting mix or compost for your microgreen tray, make sure it’s free of fertilizer or other chemicals that could be harmful to your greens. If possible, opt for an organic option with plenty of nutrients like nitrogen, phosphorus, and potassium that will encourage healthy growth.
  • Tray Drainage: The right kind of container is essential for proper drainage as well as keeping moisture levels just right. Look for trays made out of plastic or wood that have several small holes at the bottom so excess water can easily drain away from the roots. Additionally, adding a thin layer of gravel or stones below the soil can help increase drainage while also providing air pockets to keep oxygen circulating around the roots.

With these two steps taken care of, you’re now ready to start planting your microgreens! Make sure to lay down a thin layer of moistened soil at least 1/4 inch deep in each section before sprinkling seeds evenly over top. With daily watering and proper light exposure in a warm environment, you should begin seeing sprouts in no time!

Planting the Seeds

Now it’s time to sow the seeds and watch your microgreen garden bloom! When selecting a container for planting, consider the size of the tray, soil type, and drainage.

It’s important to make sure that there is adequate drainage when using plastic or ceramic containers so that excess water can be removed from the soil. Additionally, certain types of soils may not provide enough support for the roots of your microgreens, so it’s essential to choose a soil specifically designed for growing microgreens.

Once you have chosen an appropriate container and soil type, you can begin planting your seeds. Start by sprinkling your seeds evenly across the surface of the soil. If you’re using small seed varieties such as radish or mung beans, try to spread them as thinly as possible while still ensuring even coverage over all areas. For larger seeds like peas or broccoli sprouts, cluster them closer together in small groups rather than scattering them individually across the entire tray.

Watering is another critical step in successfully growing microgreens on your windowsill. Too much water will cause mold growth and may result in poor germination rates; too little water will prevent proper seed development and growth.

Water gently until it begins to pool slightly at the top layer of soil before allowing it to drain away completely — this will ensure an optimal amount of moisture without causing any harm to delicate seedlings.

Finally, cover your tray with a sheet of plastic wrap or other lightweight material to create a humid environment conducive for germination and then place it near a sunny windowsill where temperatures remain between 65-75 degrees Fahrenheit (18-24 Celsius).

Be sure to check back each day during this period and remove any condensation that builds up on top of the covering material since too much moisture can dampen seed activity during germination stages.

With consistent care and attention throughout this process, you’ll soon be able to enjoy fresh microgreens grown right on your windowsill!

Caring for Your Microgreens

Once you’ve planted your microgreens, it’s important to care for them properly to ensure they grow into healthy plants.

As with any garden, watering is essential. Water the soil just enough so that it’s moist but not soggy.

Microgreens need direct sunlight or artificial light for at least 6 hours each day in order to photosynthesize and grow.

Lastly, harvesting should be done when the leaves are 2-3 inches long. This usually occurs between 7-14 days after planting.


To keep your microgreens healthy, it’s important to water them regularly. When watering your microgreens, make sure the soil is moist but not saturated or overly wet. An ideal way to ensure proper drainage and nutrient balance is to use a tray with small holes in the bottom that allows excess water to drain out. This helps prevent root rot and other problems caused by poor drainage systems.

Additionally, you should avoid using overhead watering for your microgreens as this can cause mold growth on the leaves of the plants. Instead, use a watering can or spray bottle to direct water directly onto the soil surface.

Watering frequency will vary based on weather conditions and air temperature; however, generally speaking microgreens need watering every 1-2 days when they are young and once every 3-4 days when they are established.

Light Requirements

To help your microgreens thrive, they need to be kept in bright, indirect light for 8-10 hours a day. Photosynthesis needs can vary between species of microgreens, so it’s important to check the particular seed packet for the light requirements of the plant you’re growing.

As a general rule, however, most varieties require medium to high levels of light intensity. This can come from natural sources such as sunlight coming through a window or artificial lighting such as fluorescent or LED grow lights.

To make sure your microgreens are getting enough light and not too much direct sun exposure, position them near a bright window and rotate their tray every few days so that all sides have access to the sunlight.


When it’s time to harvest your microgreens, you’ll want to cut them near the soil line with a pair of sharp scissors – snipping off just above the roots. Depending on the type of microgreen you’re growing, this harvesting process can take anywhere from two to three weeks.

It’s important that when harvesting your microgreens, you use proper techniques in order to maximize yield and maintain quality. Make sure not to pull out roots as this can damage your crop. Once harvested, you can compost the leftover material or store it for later use.

Additionally, make sure that if harvesting by hand, gloves are worn in order to protect yourself from any potential bacteria or fungus present in the soil. With these simple harvesting techniques, you’ll be able to enjoy fresh and nutrient-rich microgreens right from your windowsill!

Enjoying Your Microgreens

Enjoying your microgreens is easy – just snip them and add them to salads, soups, sandwiches, and more! Here are some tips to help you make the most of your homegrown greens:

  • Try adding raw microgreens as a topping for tacos or burgers.
  • Give your stir-fries an extra boost of flavor by sprinkling on some freshly snipped microgreens.
  • Eating microgreens can be as simple as tossing them into salads for added crunch.
  • Get creative in the kitchen with cooking microgreens – from omelets to pesto, there’s no shortage of delicious recipes out there that call for freshly chopped greens.

No matter which way you choose to enjoy your harvest, it’s sure to bring a unique flavor and texture profile to any dish!
