Supplies Needed For Growing In A Jar

Now that you know what microgreens are, it’s time to gather the supplies needed for growing them in a jar. The most important item is obviously the jar itself. It can be any size or shape of your choosing, just make sure it has an opening wide enough so that you can fit both your hands inside when planting and harvesting. You’ll also need some microgreen seeds, soil, a watering can, and a light source.

For the soil, use a combination of peat moss and vermiculite for optimal drainage and aeration. Make sure whatever soil mixture you choose does not contain chemical fertilizers which may harm your plants. When choosing a watering can, select one with a nozzle attachment so that you have better control over how much water is dispensed into the jar. As far as lighting goes, unless you’re able to provide natural sunlight through a window sill setup, full-spectrum LED lights are usually recommended as they enable healthy photosynthesis without creating too much heat which could burn your microgreens.

Once all these components are acquired, it’s time to move on to the basics of planting microgreens in a jar…

Planting Basics

Planting microgreens in a jar is an easy process that requires minimal supplies and materials. To get started, you’ll need to select the right planting technique for your specific needs. This could involve using egg cartons, trays, or even just placing seeds directly into the jar. Once you’ve decided on your planting approach, it’s time to prepare the jars. You should clean them thoroughly with soap and water before adding soil and starting your seeds.

When selecting soil for growing microgreens in a jar, look for one specifically designed for container gardening. The soil should be light and airy so that there is enough room for roots to grow without becoming compacted. Additionally, make sure to use sterile soils which are free of weed seeds or fertilizers that could harm delicate seedlings.

Next up is establishing a watering schedule for your plants; this will depend on how often they require moisture as well as local climate conditions such as humidity levels and temperature fluctuations. It’s best to keep the soil slightly moist at all times by misting lightly each day until the sprouts emerge from their shells. After this point, you can slowly reduce frequency but continue providing adequate amounts of moisture regularly throughout the rest of their growth cycle. With these basic steps completed, you’re now ready to move onto care and maintenance of your microgreens!

Care And Maintenance

Growing microgreens in a jar may sound like the simplest gardening task there is, but believe it or not, even the smallest plants need care and attention! After all of your hard work planting those seeds into the soil, you’ll want to make sure that your microgreen creation flourishes. Here are some essential tips for keeping them healthy and thriving:

First off, watering frequency should never be overlooked! You don’t have to water every single day – once or twice per week will do – but making sure that your soil is consistently moist can help prevent wilting and keep your greens looking tip-top. Keep an eye on the temperature too; if it’s too cold then they won’t grow as quickly as they should. It’s also important to provide adequate light requirements; most microgreens prefer full sun exposure with at least four hours of direct sunlight each day.

Fertilizer application is also key when caring for microgreens. A diluted liquid fertilizer used sparingly every two weeks should be enough to give them the extra boost they need. If pests become an issue, use organic methods such as neem oil sprays instead of chemical pesticides – these are much better for your health and safer for the environment.

By following these steps above, you’ll ensure that your tiny green friends stay safe and happy throughout their growing period. Now let’s move onto harvesting tips next!

Harvesting Tips

Harvesting microgreens from a jar is an easy process. When the plants are about 2-3 inches tall and have developed their first true leaves, you can go ahead and harvest them with scissors or kitchen shears. Make sure to cut as close to the soil surface as possible for best results. It’s important to note that cutting too low will cause damage to your remaining plants in the jar. Microgreens harvesting should be done on a regular basis, so that new growth can take its place in the jar quickly.

When it comes to jar microgreens harvesting, timing is everything. You want the greens to be young enough when they’re harvested so that they don’t become tough and bitter tasting. For most varieties of microgreens, this happens around 7-10 days after planting. However, if you wait any longer than 10 days before harvesting, some of them may start getting woody which means it’s time for another round of planting!

It’s also essential to remove all dead material from your jars during the harvesting process. This includes wilted or decaying leaves as well as any weeds that might’ve sprouted up while waiting for your crops to mature. Doing this helps keep your jar environment healthy and ensures better yields in future harvests. Without proper maintenance, pests could be attracted into your jars and ruin your crops altogether.
With these tips in mind, let’s move onto common problems and solutions associated with growing microgreens at home…

Common Problems And Solutions

Picture this: You open the jar to check on your microgreens and find that they are wilting, rotting or infested with pests. Don’t panic! Even experienced gardeners face common problems when growing microgreens in a jar.

The first step is preventing rot from occurring by ensuring adequate drainage. To do this, you can use soil-less mediums like coconut fiber or vermiculite which allow excess water to drain away quickly. Additionally, make sure the container has plenty of holes for airflow and remember to keep the lid slightly off so air can circulate properly inside the jar.

Another issue may be mold growth due to improper ventilation or too much moisture trapped within the jar environment. If you spot any white patches forming on top of your greens, remove them right away as it spreads faster than you think. Adding some chamomile tea leaves into your potting mix mixture also helps prevent fungal infections while troubleshooting growth issues such as lack of nutrients or sunlight exposure. Lastly, if you discover that your plants have been attacked by pests, try using neem oil spray or diatomaceous earth powder to naturally fix the problem without harming beneficial insects around your home space.

Staying vigilant is key to resolving all these potential problems before they even start – because let’s face it; no one wants their hard work going down the drain!


To conclude, growing microgreens in a jar is an easy and fun project that can add some freshness to your home or office. It’s also a great way to get the kids interested in gardening!

My daughter recently decided she wanted to try it out, so we grabbed all of the supplies needed for our jar garden and got started. We used organic soil and planted a mixture of broccoli, kale, radishes, and arugula seeds. After about two weeks, we had lush sprouts ready for harvesting.

Harvesting was simple—we just cut off what we needed from the top with scissors. Since then, my daughter has been enjoying her own homegrown microgreens on salads and in sandwiches each day! She couldn’t be more proud of herself for taking initiative and learning how to grow food at such a young age.

Growing microgreens in jars isn’t difficult if you know what you’re doing; plus it’s an inexpensive way to enjoy fresh produce throughout the year. So why not give it a try? You never know—you may find yourself as hooked on this hobby as my daughter did!
