Basil takes about 3 to 4 weeks to grow from seed to a harvestable size, and that’s the short answer to how long does basil take to grow.
If you’ve been wondering how long does basil take to grow in your garden or on your windowsill, you’re in the right place because the timeline is actually pretty predictable.
Basil grows quickly once the soil is warm, and you can start picking fresh leaves as soon as the plant has several sets of true leaves.
Full maturity, where the plant is bushy and ready for multiple harvests, usually lands between 60 and 75 days from sowing, but you don’t have to wait that long to enjoy it.
In this post, we’ll break down how long does basil take to grow at each stage, what affects the timeline, and how you can speed things up.
Let’s dig into the details.

In this post, we’ll break down how long does basil take to grow at each stage, what affects the timeline, and how you can speed things up.
Let’s dig into the details.
How Long Does Basil Take To Grow From Seed
The time it takes basil to grow from seed starts with germination, which is the very first stage.
Basil seeds germinate in about 5 to 10 days when the soil temperature sits between 70°F and 85°F.
That means basil takes about a week to grow from a seed into a tiny sprout with its first two cotyledon leaves.
After germination, the seedling stage lasts another 2 to 3 weeks, and during this time, the plant develops its first true leaves.
So when you add it up, basil takes about 3 to 4 weeks to grow from seed to the point where you can start harvesting small leaves.
The key here is warmth because basil takes longer to grow if the soil is cooler than 70°F.
If you’re starting seeds indoors, consider using a heat mat to speed up how long basil takes to grow from seed.
1. Germination Stage (Days 5–10)
The very first step in how long does basil take to grow is the germination period.
Seeds absorb water, swell, and crack open, sending out a tiny root called a radicle.
Within a week or so, you’ll see the sprout push above the soil surface.
The germination stage is quick, but it only happens fast if you keep the soil consistently moist.
Letting the soil dry out even once can slow down how long basil takes to grow from this stage.
So check the top layer of soil daily and mist it gently if it looks dry.
2. Seedling Stage (Days 10–28)
Once the sprout appears, the basil plant enters the seedling stage, which lasts about 2 to 3 weeks.
During this time, the first true leaves emerge, and those are the leaves you’ll actually harvest later.
Basil takes longer to grow true leaves if it doesn’t get enough light, so place seedlings under a grow light or on a sunny south-facing windowsill.
You’ll know the seedling stage is over when the plant has 3 to 4 sets of true leaves.
At that point, which is usually around day 21 to 28, you can start pinching off the top leaves to encourage bushier growth.
So, basil takes about a month to grow from seed to a small harvestable plant.
How Long Does Basil Take To Grow To Full Size
While you can harvest early, basil takes about 60 to 75 days to grow to full size, meaning a mature plant that’s 12 to 24 inches tall.
At this stage, the plant is bushy, with multiple side shoots, and you can harvest large handfuls of leaves.
How long does basil take to grow to full size depends largely on the variety you’re growing.
For example, sweet basil (Genovese) tends to grow a bit slower, while Thai basil and lemon basil may reach maturity faster.
But generally, basil takes about two months to grow from seed to a full, productive plant.
If you started your basil indoors early, basil takes about 3 to 4 weeks to grow to transplant size, and then another 4 to 6 weeks in the garden.
1. Temperature and Sunlight Matter
Basil is a warm-season herb, so how long basil takes to grow is heavily influenced by heat.
If temperatures dip below 50°F, growth slows way down or stops completely.
On the flip side, basil takes less time to grow when it gets at least 6 to 8 hours of direct sunlight each day.
More sun means more photosynthesis, which means faster leaf production and a shorter overall timeline.
If you’re growing indoors, a grow light can reduce how long basil takes to grow by several days.
2. Watering and Soil Quality
Basil takes about the same amount of time to grow regardless of soil, but the quality affects health and yield.
Well-draining, nutrient-rich soil with a pH between 6.0 and 7.0 is ideal.
Keep the soil evenly moist, but don’t drown the roots because waterlogged soil can lead to root rot, which stops growth entirely.
A balanced fertilizer applied every 4 to 6 weeks can also speed up how long basil takes to grow by providing steady nutrition.
How Long Does Basil Take To Grow After Pruning
If you harvest basil regularly, you might wonder how long does basil take to grow back after you cut it.
Basil takes about 1 to 2 weeks to grow back after pruning, depending on the season and conditions.
When you pinch off a stem just above a leaf node, the plant sends out new shoots from that point.
So basil takes roughly 7 to 14 days to regrow enough leaves for another light harvest.
This regenerative quality means you can get continuous harvests all season long.
The trick is to never cut more than one-third of the plant at a time, and always leave at least 2 sets of true leaves.
Following this rule, basil takes about two weeks to regrow between harvests, and you’ll have fresh basil for months.
So, How Long Does Basil Take To Grow Overall
Basil takes about 3 to 4 weeks to grow from seed to a harvestable size, and full maturity lands around 60 to 75 days.
The exact time basil takes to grow varies with temperature, sunlight, watering, and variety, but the ranges we covered above hold true for most home gardens.
If you’re asking how long does basil take to grow because you’re eager for fresh pesto, start harvesting around day 21.
And remember, basil takes about 1 to 2 weeks to regrow after each pruning, so your plant keeps giving.
Hope this clears up how long does basil take to grow and helps you plan your herb garden with confidence.
Happy planting, and enjoy your homegrown basil.
