You can grow basil and parsley outdoors successfully by giving them the right balance of sun, water, and soil.
If you’ve been wondering how to grow basil and parsley outdoors, you’re in luck because both herbs are surprisingly forgiving for beginners and pros alike.
The trick to growing basil and parsley outdoors is understanding that they have slightly different needs, even though they share a garden bed beautifully.
Basil craves heat and plenty of sunshine, while parsley is a bit more tolerant of cooler temperatures and partial shade.
In this post, we’ll walk through how to grow basil and parsley outdoors from seed to harvest, covering spacing, watering, soil prep, and common pitfalls so you can grow basil and parsley outdoors with confidence.
Let’s dig in and get those herbs thriving in your garden.
How to Grow Basil and Parsley Outdoors: The Basics
When you’re learning how to grow basil and parsley outdoors, the first thing to master is timing and location.
Both herbs want a spot that gets at least six hours of direct sunlight, though parsley can handle a little afternoon shade in hot climates.
You can grow basil and parsley outdoors in raised beds, containers, or directly in the ground, as long as the drainage is good.
These two herbs also appreciate rich, loamy soil with plenty of organic matter mixed in before planting.
Let’s break down the specific steps for each herb so you know exactly what to do.
1. Start With the Right Soil for Basil and Parsley
The soil is the foundation for how to grow basil and parsley outdoors, and both herbs prefer a pH between 6.0 and 7.0.
Work in compost or aged manure a week before planting to give your herbs a nutrient boost.
Good drainage is critical because basil and parsley both hate soggy roots that can lead to rot.
If you’re gardening in heavy clay, consider raising the bed or mixing in sand or perlite to improve aeration.
Test your soil with a simple kit from the garden center to see if you need to adjust the pH before you grow basil and parsley outdoors.
2. When to Plant Basil and Parsley Outdoors
Knowing when to plant is a huge part of how to grow basil and parsley outdoors successfully.
Basil is a warm-season annual, so you should only move it outdoors after the last frost date has passed and nighttime temps stay above 50°F.
Parsley is hardier and can be planted outdoors two to three weeks before that final frost because it tolerates light cold snaps.
If you start seeds indoors, you can grow basil and parsley outdoors by transplanting after a week of hardening off.
For direct sowing, wait until the soil has warmed up to at least 60°F for basil, while parsley seeds will germinate in cooler soil.
3. Spacing and Planting Depth for Both Herbs
When you’re figuring out how to grow basil and parsley outdoors, spacing makes a big difference in airflow and disease prevention.
Basil plants should be spaced about 12 to 18 inches apart so their bushy leaves have room to spread.
Parsley can be planted a bit closer at 6 to 10 inches apart, but still give it enough space to grow into a full clump.
Sow basil seeds at a quarter-inch depth, and parsley seeds at a shallow depth of about an eighth to a quarter inch.
Remember that parsley seeds are slow to germinate, often taking two to three weeks, so don’t panic if you don’t see sprouts quickly when you grow basil and parsley outdoors together.
Watering and Feeding for Growing Basil and Parsley Outdoors
Water is where most people mess up when they try to grow basil and parsley outdoors, so let’s get it right.
Both herbs like consistent moisture, but they absolutely hate being waterlogged.
The goal is to keep the top inch of soil evenly moist, watering deeply once or twice a week depending on your climate.
Mulching around the base of your plants helps retain moisture and keeps the roots cool during hot summer days.
As for feeding, you can grow basil and parsley outdoors with just a light application of balanced fertilizer every four to six weeks.
Avoid high-nitrogen fertilizers because they’ll give you huge leaves but less flavor and aroma.
1. Best Watering Schedule for Basil
Basil is a thirsty plant, but it also prefers that the foliage stays dry to prevent fungal issues.
Water at the base of the plant in the morning, which gives the leaves time to dry off during the day.
If you notice the leaves drooping in the afternoon, that’s a sign your basil needs more water.
During heatwaves, you may need to water every other day to keep basil happy when you grow basil and parsley outdoors.
Just check the soil with your finger, if it feels dry an inch down, it’s time to water.
2. Parsley’s Watering Needs
Parsley is a bit more forgiving with moisture, but it still needs steady hydration to stay lush.
You can grow basil and parsley outdoors with the same watering routine if you group them, but parsley can tolerate a little less.
Yellowing leaves on parsley often mean overwatering, while droopy, crispy leaves mean underwatering.
Aim for about one inch of water per week, and increase that if you’re in a dry region.
Using a soaker hose or drip irrigation is ideal because it keeps water off the leaves and targets the roots.
Light and Temperature Tips for Basil and Parsley Outdoors
Light and temperature are the backbone of how to grow basil and parsley outdoors, and they’re not identical here.
Basil loves full sun, the more direct sunlight the better, so give it the brightest spot you have.
Parsley does well in full sun to partial shade, especially in warmer zones where afternoon sun can be too harsh.
If you live in a hot climate, you can grow basil and parsley outdoors with a little afternoon shade for parsley and mulch to cool the soil.
Basil is extremely sensitive to cold, so any dip below 50°F can stunt it or turn leaves black.
Parsley can handle frost better, and in mild climates, you might even get it to last through the winter.
Harvesting Basil and Parsley Outdoors for Continuous Growth
The real reward of learning how to grow basil and parsley outdoors is harvesting, and the method matters.
For basil, always pinch off leaves from the top of the stem, just above a pair of leaves, to encourage bushier growth.
Never strip the plant bare, leave at least two sets of leaves on the lower stem so it can keep photosynthesizing.
For parsley, cut the outer stalks first at the base, leaving the inner ones to keep growing.
If you grow basil and parsley outdoors this way, you’ll get a steady harvest for months instead of one big cut.
Regular harvesting also prevents basil from flowering, which turns leaves bitter and signals the plant to stop leaf production.
Parsley will keep producing all season long if you keep removing the older outer stems before they yellow.
Common Problems When Growing Basil and Parsley Outdoors
Every gardener faces a few hurdles when they grow basil and parsley outdoors, but most are easy to fix.
Bolting is a big one for basil, when it flowers early due to heat or stress, so pinch those buds off as soon as you see them.
Parsley can also bolt in its second year, which is normal for a biennial, but you can delay it by keeping it cool and well-watered.
Yellowing leaves on either herb usually point to watering issues or nutrient deficiencies, so check your soil moisture first.
Pests like aphids and spider mites love basil, while parsley attracts swallowtail caterpillars, which are actually a sign of a healthy garden.
You can grow basil and parsley outdoors with simple fixes like neem oil for pests and proper spacing to avoid mildew.
Just stay observant and take action early, and your herbs will bounce right back.
So, How Do You Grow Basil and Parsley Outdoors?
You can grow basil and parsley outdoors by giving each herb the right sun, water, and soil tailored to its needs.
Basil needs full sun, warm nights, and steady watering at the base to thrive.
Parsley is more tolerant of cool weather and partial shade, making it a great companion for basil in most gardens.
The best approach is to grow basil and parsley outdoors in well-draining soil enriched with compost, spacing them properly for airflow.
Water deeply but infrequently, and always harvest from the top or outer stems to encourage continuous new growth.
Watch for early flowering, adjust for heat, and keep pests in check, and you’ll have fresh herbs all season.
So, if you’ve been asking how to grow basil and parsley outdoors, you now have the full roadmap to do it successfully.
Get your seeds or seedlings in the ground, stay consistent, and enjoy the tastiest, most aromatic herbs from your own garden.
