Taking care of basil plants is easier than you might think, and the rewards are absolutely worth it.
When you learn how to take care of basil plants properly, you’ll have a constant supply of fragrant, flavorful leaves for your kitchen.
Basil is one of the most forgiving herbs to grow, but it does have specific preferences that make the difference between a bushy plant and a sad, leggy one.
In this post, I’ll walk you through everything you need to know about how to take care of basil plants, from watering and sunlight to pruning and harvesting.
So let’s get your basil thriving!
How to Take Care of Basil Plants: The Basics
The first thing to understand about how to take care of basil plants is that they’re sun-loving, warmth-seeking herbs.
Basil plants crave at least six to eight hours of direct sunlight every single day.
If you’re growing them indoors, place them by a south-facing window where they can soak up those rays.
Outdoors, choose a spot in your garden or on your balcony that gets full sun without too much shade.
When you take care of basil plants with enough light, the leaves stay green, dense, and packed with essential oils.
Without that sunlight, the plant stretches out, becomes weak, and loses its signature flavor.
Another core part of how to take care of basil plants is soil, and basil likes it rich, well-draining, and slightly moist.
A good quality potting mix or garden soil with compost mixed in will give your basil exactly what it needs.
Now, let’s break down the specific steps for caring for basil plants so you can avoid the common pitfalls.
1. Watering Your Basil Plants Correctly
Watering is where most people struggle when learning how to take care of basil plants.
Basil plants hate to be waterlogged, but they also hate drying out completely.
The trick is to keep the soil consistently damp, not soaking wet.
You can check the soil by sticking your finger about an inch into the dirt, if it feels dry, it’s time to water.
When you water basil plants, always water at the base of the plant, not over the leaves.
Watering the leaves can invite fungal diseases like powdery mildew, which ruins the plant.
In the heat of summer, you might need to water daily, while in cooler months, every few days is enough.
If you’re growing basil in a pot, make sure the container has drainage holes so excess water can escape.
2. Soil and Fertilizer Needs
Another part of how to take care of basil plants is feeding them the right nutrients.
Basil plants are heavy feeders, meaning they use up a lot of energy to produce those big, aromatic leaves.
Start with a rich, organic potting soil that includes compost or aged manure.
Then, about once a month, give your basil a balanced liquid fertilizer diluted to half strength.
Too much fertilizer, though, can actually make the leaves taste bitter, so don’t overdo it.
If you’re growing basil in the ground, amend the soil with compost before planting, and that’s often enough.
When caring for basil plants, good soil equals healthy roots, and healthy roots equal lush foliage.
The Best Way to Water and Feed Basil Plants
Let’s dig a little deeper into the best practices for watering and feeding, because these are the heart of caring for basil plants.
Basil plants are sensitive to temperature changes in their soil, so use room-temperature water when you can.
Cold water can shock the roots and slow down growth.
Also, consider mulching around the base of your outdoor basil plants.
Mulch helps lock in moisture, keeps the soil cool, and reduces how often you need to water basil plants.
As for feeding, an organic seaweed or fish emulsion fertilizer works wonders.
These natural options provide trace minerals that make the leaves more aromatic and flavorful.
When you carefully water and feed basil plants, you’ll notice new growth appear almost overnight.
3. Pruning and Harvesting Basil Plants
A big part of how to take care of basil plants involves regular pruning, and this isn’t just for harvesting.
Pruning encourages the plant to branch out, making it bushier and fuller instead of tall and spindly.
You should start pinching off the top sets of leaves once the plant has at least six true leaves.
When you prune basil plants, always cut just above a pair of leaves, not below.
New stems will grow from that cut point, creating two branches where there was one.
Also, keep an eye out for flower buds, if you see them forming, pinch them off immediately.
When basil flowers, the leaves turn bitter and the plant focuses energy on seed production rather than foliage.
So the secret to caring for basil plants is constant, gentle pruning to keep them in the leafy growth stage.
Harvesting is just an extension of pruning, simply pick leaves as you need them for cooking.
For bigger harvests, cut whole stems about a third of the way down, this stimulates fresh growth.
Common Problems When You Take Care of Basil Plants
Even when you follow all the right steps, sometimes problems pop up, and that’s okay.
Part of learning how to take care of basil plants is knowing how to spot trouble early.
Yellow leaves usually mean overwatering, so let the soil dry out a bit between waterings.
Wilting leaves, on the other hand, often mean underwatering, especially on hot days.
If the leaves have brown spots or a dusty white coating, you might be dealing with a fungal issue.
Good airflow and watering at the base of basil plants prevents most of these diseases.
Pests like aphids and spider mites also love basil, so check the undersides of leaves regularly.
A gentle spray of soapy water can take care of mild infestations.
4. Indoor vs. Outdoor Basil Plants
Your approach to caring for basil plants will differ slightly depending on whether they live indoors or outdoors.
Indoor basil plants need the most attention when it comes to light, as window light can be weaker than direct sun.
Consider using a grow light for indoor basil plants, especially during the winter months.
Outdoor basil plants, though, need protection from strong winds and heavy rain.
If a storm is coming, move pots under a covered porch or shelter.
Both indoor and outdoor basil plants appreciate a consistent temperature between 70°F and 80°F.
Cold drafts or sudden temperature swings will stress out your basil plants.
So when you take care of basil plants, think about their environment as much as their watering schedule.
So, How Do You Take Care of Basil Plants?
When you take care of basil plants, you’re really just giving them the three things they love most: sun, water, and attention.
Basil plants need direct sunlight for at least six hours a day, consistent moisture, and regular pruning.
You should water basil plants at the base, feed them monthly with a mild fertilizer, and never let them flower.
By following these simple steps for caring for basil plants, you’ll avoid the most common mistakes that kill this herb.
Remember, how to take care of basil plants is not complicated, it just requires a little routine.
So go ahead, get your hands dirty, and soon you’ll be harvesting fresh basil for pasta, salads, and pesto all season long.
Your basil plants will thank you with an endless supply of delicious, fragrant leaves.
