When To Plant Microgreens

The best time to plant microgreens is any day of the year, because these tiny greens thrive indoors without needing a traditional outdoor growing season.
 
When you’re wondering when to plant microgreens, the simple truth is that you’re in complete control of the schedule, unlike with regular garden vegetables.
 
You can plant microgreens in the dead of winter, the heat of summer, or any random Tuesday, as long as you have a sunny windowsill or a basic grow light.
 
Since they’re harvested just days after germination, the timing is less about the calendar and more about your own meal planning and daily routine.
 
In this post, we’ll explore the best times to plant microgreens, how to schedule multiple batches for a continuous harvest, and the ideal conditions that make any day perfect for planting.
 
Let’s dig into the timing that works for your kitchen and your taste buds.
 

Why You Can Plant Microgreens All Year Round

You can plant microgreens at any point in the year because they don’t depend on outdoor temperatures, soil warmth, or daylight hours.
 
Unlike herbs or leafy greens grown in the garden, microgreens are almost always grown indoors on a countertop or shelf where you control the climate.
 
This means the question of when to plant microgreens is answered by your own preferences, not by the frost date in your region.
 
Here’s why this indoor growing method opens up every single day as a potential planting date.
 

1. Microgreens Don’t Need Outdoor Heat

Outdoor crops need specific soil temperatures to germinate, but microgreens are perfectly happy with typical indoor room temperatures between 65°F and 75°F.
 
You can plant microgreens in the middle of January, and as long as your house is reasonably warm, they’ll sprout within a few days.
 
That’s why the best time to plant microgreens is simply whenever you can maintain a comfortable indoor environment.
 

2. Artificial Lighting Replaces the Sun

Even on the darkest winter days, a simple LED grow light provides the exact spectrum microgreens need to photosynthesize and develop vibrant colors.
 
So, when to plant microgreens in low-light months?
 
Just place your trays directly under a grow light for 12 to 16 hours a day, and they’ll grow just as well as they would in bright summer sunlight.
 
You can plant microgreens on a schedule that ignores seasonal sun patterns entirely.
 

3. Short Growing Cycles Mean Fast Turnaround

Most microgreens are ready to harvest just 7 to 21 days after you sow the seeds.
 
Because the growth window is so short, you don’t have to wait for a specific planting season to enjoy a fresh harvest.
 
This is the main reason you can plant microgreens every single week and always have a steady supply.
 
The calendar is irrelevant when your crop is ready in less than a month.
 

The Best Times To Plant Microgreens For Continuous Harvest

The best time to plant microgreens for a constant supply isn’t a single date, it’s a weekly rotation system.
 
Instead of asking when to plant microgreens once and waiting, you’ll want to stagger your sowing to create a rolling harvest.
 
Here’s how to time your plantings so you never run out of fresh greens.
 

1. Start A New Tray Every 3 To 4 Days

To keep a continuous harvest, the best time to plant microgreens is every few days, not once a month.
 
For example, if you sow a tray of radish microgreens on Monday, you’ll plant another tray on Thursday, and another on Sunday.
 
This way, you’ll always have one tray germinating, one tray growing, and one tray ready to harvest.
 
You can plant microgreens on this rolling schedule indefinitely without any gaps in your supply.
 

2. Align Planting With Your Meal Prep Day

A great time to plant microgreens is right after you do your weekly grocery shopping or meal prep.
 
If you’re making salads or smoothies on Sundays, sow a new tray that same day so you’ll have fresh greens ready in about two weeks.
 
This practical approach ties your planting schedule directly to how you actually eat.
 
The best time to plant microgreens becomes any day that fits neatly into your cooking routine.
 

3. Account For Different Varieties’ Growth Rates

When planning when to plant microgreens, remember that not all varieties grow at the same speed.
 
Fast growers like broccoli, radish, and mustard are ready in 7 to 10 days, while slower ones like beet, basil, and cilantro take 14 to 21 days.
 
If you want a mix of flavors, plant fast growers a week later than your slow growers so they all finish around the same time.
 
You can plant microgreens with this staggered timing to ensure a diverse harvest ready at once.
 

Seasonal Considerations For Planting Microgreens

While you can plant microgreens year-round, certain seasons do require small tweaks to your growing setup.
 
The best time to plant microgreens in summer might be in a cooler basement, while winter plantings might need extra grow light hours.
 
Here’s how to adapt your timing to each season for the best results.
 

1. Planting Microgreens In Winter

Winter is actually one of the best times to plant microgreens because the dry indoor air helps prevent mold and damping-off.
 
However, you’ll need to rely almost entirely on grow lights since natural sunlight is weak and limited.
 
You can plant microgreens in December just as easily as in June, just give them 16 hours of artificial light and keep them away from cold drafts.
 

2. Planting Microgreens In Summer

Summer heat can be a challenge if your indoor temperatures climb above 80°F, which may slow germination.
 
The best time to plant microgreens on hot days is early morning, or you can move trays to the coolest part of your home.
 
You can plant microgreens in summer successfully by ensuring good airflow and keeping the soil moist but not waterlogged.
 

3. Spring And Fall Are Naturally Forgiving

If you’re new to growing, spring and fall are the most forgiving times to start because temperatures are mild and sunlight is moderate.
 
You can plant microgreens in these transitional seasons with less worry about heat stress or light deficiencies.
 
It’s still not mandatory to wait, but these seasons make the learning curve much easier for beginners.
 

How To Know The Exact Right Moment To Plant Microgreens

If you’re still wondering when to plant microgreens, just look at your own kitchen counter and your appetite.
 
The exact right moment is when you have an empty tray, a bag of seeds, and about ten minutes of free time.
 
You can plant microgreens in the morning with your coffee, during a lunch break, or after dinner as a relaxing activity.
 
There’s no wrong moment, as long as you’re not trying to germinate seeds in freezing cold or scorching heat.
 
So, keep it simple and pick a day that works for you.
 

1. Check Your Seed Packet For Specific Days To Maturity

Your seed packet will tell you how many days each variety needs from sowing to harvest.
 
Use this number to work backward from when you want to harvest.
 
For example, if you want fresh sunflower microgreens for a special dinner in 10 days, plant them today.
 
This is the most reliable way to determine when to plant microgreens for a specific event.
 

2. Consider Your Watering Schedule

You’ll need to water microgreens daily or every other day, so plant them when you know you’ll be home to care for them.
 
Avoid planting microgreens right before a long vacation or an overly busy week.
 
The best time to plant microgreens is when you have a few days of consistent routine ahead of you.
 

So, When Is The Best Time To Plant Microgreens?

The best time to plant microgreens is any day you’re ready to commit to a quick and rewarding growing cycle.
 
You can plant microgreens in the depths of winter or the peak of summer because you control the environment completely.
 
Your only real job is to pick a variety you love, grab a seed tray, and find a spot with warm temperatures and a light source.
 
Don’t overthink the calendar, because microgreens are the most forgiving crop when it comes to timing.
 
Hope this guide clears up when to plant microgreens, and now you can confidently start your first tray today.
 
Happy growing, and enjoy your fresh, homegrown greens!
