Freshly picked peas are loaded with natural sugars that quickly turn to starch – so if you haven’t had peas off the vine before, you’ve never experienced their absolute deliciousness!
Sprouts in 2 weeks. Harvest from Week 6 on
Equivalent of 6+ hours of direct sun [DLI of 18+ mol/m²/day].
Beginner friendly. Once its producing – you’ll have to harvest every couple days.
Best Peas varieties to grow inside
Peas have been part of our diet for thousands of years, but it’s only recently that breeders developed much tastier varieties than existed even 20 years ago (in fact the classic “snap pea” is only about 40 years old)! Since then, many other snap peas have been developed and are our favorite of the category. They came from cross-breeding snow peas (where you only eat the shell) with Garden Peas, which you shell and eat the peas. We much prefer the others that we can eat the pods whole – the best to grow indoor are:
Stays under 2 ft tall and resistant to many diseases.
No need to wait for peas to form – this delicate plant is entirely edible with no spindly tendrils.
Super Sugar Snap
If you’ve got more space or a good trellis, this vining type will give you gallons of peas.
Oregon Sugar Pod II
Yummy stringless pods on a compact plant (~ 2ft).
Best Setup for Peas Plants
Ceramic Self Watering Planter (preferred) or pot that is at least 6″ / 1 quart.
Standard Potting Mix
At the start: Herb Blend. This should be high in nitrogen (with NPK numbers like 10-5-5).
Ongoing: Vegetable Blend. This should be high in phosphorus and low in nitrogen (with NPK numbers like 4-10-6).
A strong grow light that can give the equivalent of 6+ hours of direct sun [DLI of 18+ mol/m²/day].

Preparing your Planter & Watering Schedule for Peas
Peas plants do well in moist soil conditions. If the soil dries out completely the roots will die back and it will be tough for the plant to recover. On the other hand, if the roots are exposed to standing water for too long, they can rot.
A Ceramic Self Watering Planter filled with a standard potting mix self-regulates to keep the soil at consistent moisture for your plant to thrive (and no watering guesswork for you).
To set one up:
- Fill up the planter with dry soil from the bag, gently tamping down the top.
- Dump the soil into a large mixing bowl and add water until the soil is moist, but not sopping wet (about ½ Cup)
- Mix in 1 tablespoon of the Herb Blend Plant Food.
If you are using a regular pot instead, it should be a little bit bigger (at least 6″ / 1 quart and will need drainage holes to prevent it from being over watered. Let the top of the soil dry out between watering.
Starting your Peas: Seed vs Propagate
Peas are best to start from seed in the area they will grow to their full size (known as “direct sowing”). They don’t handle transplanting well and tend to grow quicker from seed than propagating from a cutting – so we don’t see the point of starting them anyway except for from seed.
How to Plant Peas seeds
Peas grow quickly from seed. Plant 3 sites in a 6″ / 1-quart container. In larger containers, space sites 2″ apart. For each site plant, 2 seeds 1″ deep. Keep the soil warm ( 40-85°F, ideally 75°F). Sprouts typically appear in 9 days but can be as quick as 7 days or as long as 14 days depending on your conditions.
Where to grow your Peas plants
While you should take advantage of the sun (it’s free and perfect for plants) there are limited circumstances where indoor natural light is enough for Peas plants to grow well. A very bright window can cut your grow light needs in half, but if you want to grow lots of Peas, you’ll still need one. For an introduction to grow lights, head over to our post on grow lights for indoor gardeners. We’ve also got a buying guide for screw in types, but to keep things simple in this guide, we’ll just provide directions for the 24W Screw in Bulb by Sansi, which we think is a good middle of the road option.
How bright should your grow light be?
Peas plants need the equivalent of 6+ hours of direct sunlight [DLI of 18+ mol/m²/day] to grow their best. In order to provide an equivalent amount with a grow light, it needs to be pretty bright! The 24W Sansi bulb should be placed 6 inches away from the top of the plant. This will give your PPFD (the standard measure of brightness) of 500 μmol/m²/s.
How many hours per day do your Peas plants need under a grow light?
Peas plants are what’s known as “day-neutral” so can grow under a range of daylight lengths. In order for them to get enough light, we recommend setting up a timer to leave it on for 12+ hours per day.
Extend your harvest by keeping the Temperatures Cool
Peas are known as “cool weather” vegetables, and will start to slow down (or totally stop) once temperatures rise over 75If they survive the hot weather period then they’ll start producing again once temperatures cool down.
Week 2: Check for Sprouts
You could see seedlings in as little as 7 days (though 9 days is more typical). If it’s been 14 days and you still don’t have any sprouts, it’s likely that your setup is too cold.
Week 3: Check Your Seedlings
There’s no need to thin Peas, but you should check on your seedlings’ progress to make sure you’ve got enough light. They should be about 2 inches tall by the end of Week 3. If they aren’t you likely need a bit more light.
Month 1: How to Prune & Trellis Peas Plants
Peas plants are vines that will continue to grow and grow – so a monthly trim will be a necessary part of your care routine. You’ll make your first cut at about the second month, or when you have 5 branches and a growing tip, cut (or just pinch) off the main stem above the 5th branch. By removing the growing tip, you’re having the plant focus its energy into those 5 branches. There are several support options, ranging from cages to stakes, but we like to train those 5 branches up a fan trellis with plant clips.
After this, pruning and trellising is more of an art (fortunately an art that’s hard to mess up) but the general things you’ll want to look of for when:
- A main stem is going past your grow area. Pinch of the growth tip where you want it to stop.
- A heavy cluster of Peas starts to form. The weight can snap the vine, so clip right above the cluster to the trellis to avoid this (mildly heartbreaking) event.
- The plant is getting so dense that light and air can’t get in. Keep up with interior pruning to have a tidy “bonsai” Peas plant.
Week 5+: How to Pollinate Your Peas Flowers
Peas are self-fruitful, so there is no need to pollinate the flowers. After the flowers form, it generally takes 3 weeks until they are ready to pick.
Week 6: How to Harvest Peas
The rule for these is to “pick um often and pick um all.” Peas are at the peak sugar stage for a short time, so you need to pick often to catch the small window of the best flavor. When vegetables start to form it’s helpful to experiment a bit to find out what they are like at peak flavor for you – but generally they should plump out a little bit on the sides. If you miss a single pea (and they’re good at hiding!) and it grows to maturity then these plants end their life cycle early. By preventing the plant from finishing that last step of making seeds, you are able to keep it producing vegetables for much longer.
Month 12+: End of Life
As long as conditions are cool and you don’t miss any harvests, your pea plant can keep producing for over a year.

The right supplies can take the guesswork out of caring for your plants – and turn care from a daily to weekly routine. Through our grow tests, we’ve found these products to produce the best indoor Peas (and also have simple maintenance). Plants are adaptable and can grow in many different conditions, so they are by no means necessary if you already have other supplies.
