Learn how to grow parsley in containers. Growing parsley in pots and its care is easy if you know the basic requirements!
Start planting parsley seeds indoors in the early spring when you start to feel the warmth in the air, usually 6 – 10 weeks before the last frost date expected, you can always plant late as overwintering parsley is not difficult.
If you’re living in a hot climate (i.e. USDA Zones– 10 – 11), start growing parsley after the end of the summer in fall (autumn) and winter, when the weather starts to cool down.
Growing Parsley from Seeds
Parsley seeds are notorious for their low and slow germination rate. They can take up to 6 weeks to germinate and sometimes more. So expect 3 – 5 weeks to see baby plants coming out. For quicker germination, soak seeds overnight.
Directly sow the seeds 1/4 – 1/8 inch deep in the desired containers as parsley has a long taproot and it doesn’t like much being transplanted, thin the seedlings as they emerge and become 2 – 3 inches tall. Optimum germination temperature is between 60 – 80 F (15 – 27 C).
You can also propagate parsley from cuttings. For this, cut a 4 – 5 inches long stem with a few leaves on top from the plant and place it an inch deep in the pot. Maintain the moisture and keep the cutting in a shady spot that receives indirect light, wait for a couple of weeks for the emergence of roots.
Parsley Types you Can Grow
There are three types of parsley used commonly in the kitchen– Flat Leaf Parsley or Italian Parsley, Curly Leaf Parsley, and Hamburg Parsley.
- Flat Leaf Parsley– This variety has more vibrant, stronger and sweeter flavor than any other type of parsley and that’s why it’s used more in cooking. It grows a little taller and lanky and needs a wider pot to sprawl out than the curly leaf parsley. Also, the flat leaf parsley is more heat tolerant.
- Curly Leaf Parsley– Curly leaf parsley is sweet and has a soft flavor. It is used mainly for garnishing and in salads. It is smaller in size and more controlled in growth unlike the previous one.
- Hamburg Parsley– A lesser known parsley variety, grown for its swollen, edible, parsnip-flavored roots that can be used as a vegetable, while the upper part (leaves) can be used like flat leaf parsley. Growing it is similar to other parsley varieties.
Choosing a Pot
Parsley is a biennial herb but also grown as an annual. If growing parsley as an annual, you can choose a small pot about 8 inches deep minimum. For growing parsley as a biennial, choose a rather large pot, 10 – 12 inches deep and wide similarly or more, you can grow one or two plants in such a pot.
Requirements for Growing Parsley in Pots
For growing parsley in pots, choose a location that is sunny or partially shaded if you live in a cool or moderately warm climate.
If you live in a hot subtropical or tropical climate, keep the plant in a spot that receives partial sun.
Use quality potting soil that is well-drained, loamy and rich in organic matter. You can add 1 part aged manure or compost for every 2 parts potting soil.
Water parsley regularly and evenly to keep the soil slightly moist but not overly wet all the time. Never allow the soil to dry out completely and avoid overwatering!
Applying fertilizer is not necessary if your soil is rich in organic matter. Adding aged manure or compost is enough. However, you can use half-strength balanced liquid fertilizer bi-weekly if your plant is not doing well.
Parsley Plant Care
Deadheading and Pruning
Remove the flower stalks if they appear to promote foliage growth. Also, pick the dead and faded leaves time to time to keep your plant in shape.
Pests and Diseases
Leaf spot and rot are one of the most common diseases. You can save your parsley plant from root rot and crown rot by avoiding the waterlogged soil. Parsley worm, aphids, mites, and cutworm can affect this herb, so keep an eye on them.
Growing Parsley Year Round
Growing parsley indoors is a way to grow it year round, by this, you can overwinter this culinary herb. It’s easy! The plant will survive in your average room temperature and you’ll be able to harvest some leaves in winter if you keep the pot on a window that receives a few hours of direct sunlight daily.
In Subtropics and Tropics
In hotter areas (USDA Zone 10, 11), you can save your parsley plant from dying in summer. Just keep it in a cool and shady spot where it receives only a 3 – 5 hours of morning sun daily and water generously!
Harvest parsley leaves when you need. You can start harvesting parsley 2 – 3 months after planting. Wait until the stems are divided into three sections. Instead of only picking the leaves from the top, cut the entire stem carefully from the base as parsley stems are also edible and tasty. Do this from the outer portion and let the inner portion grow.
