What Not to Plant with Parsley

When planting parsley, it’s also important to know which plants make not-so-good companions. While there are some vegetables and herbs that grow nicely together with parsley, planting others too close to parsley can stunt its growth, among other things.

Below are examples of bad companions for parsley. Of course, there are others, but these are among the worst ones.

How to Grow Parsley

This is an easy-to-grow herb, making it the perfect choice for beginner gardeners. To get it started, you’ll need to sow the seeds about ¼ inch deep into evenly moist soil.

For better germination rates, mix in a bit of aged compost or peat moss.

Once your plants are about six inches tall and have ample leaves, you can start harvesting by snipping off a few of the outer leafy stems of each plant. This will also encourage your plants to become bushier.

You can harvest this herb again and again throughout the season.

Fertilizer Requirements

When growing parsley, you should know that it prefers well-drained, rich soil and a moderate amount of fertilizer.

To make sure the plant is getting the nutrients it needs, consider adding organic fertilizer to your soil before planting. This way, you’re giving the plants a boost right off the bat.

You should also consider adding a nitrogen-rich fertilizer once or twice during the growing season. This will ensure that your plant has access to all the nutrients it needs during its active growth period.

Garden Pests

Garden pests can be a real nuisance when it comes to gardening, and parsley is no exception.

Parsley is prone to attacks by a few common garden pests, including aphids, armyworms, and cabbage loopers [1]. Therefore, be on the lookout for them and incorporate some natural pest control measures if you happen to come across any of these pests.

Plant Diseases

You should also think about plant diseases that might be harmful. Plant diseases can be caused by fungi, bacteria, and viruses, among other things, and can be very damaging to your plants if the conditions are right.

Examples of plant diseases that can affect parsley include leaf spot, powdery mildew, damping off, and Alternaria leaf blight [2].

Taking preventative measures, such as avoiding contaminated soils, is essential for keeping your parsley healthy. Also, researching these plant diseases will prove helpful if the need arises for treatment.

How to Harvest

Now let’s talk about harvesting this super herb!

Harvesting parsley at the right time is key to getting the most flavor. Harvest it when the leaves are green and fresh and before the flowers start blooming.

Also, be sure not to pull out the entire plant—just grab a few outer leafy stems and use clean kitchen shears.

This will give your parsley time to regrow for a few more harvests throughout its growing season.

How to Store

You will also have to find ways of storing parsley so that you can use it over several months without needing to wait for new plants to mature. And luckily, there are various methods for doing this.

One is to place it in water. This is where you cut off the bottom leaves of the plants and bundle them up by stem before placing them in a jar with one inch of water. Next, place a loose plastic bag over the jar and store it in the fridge.

Another method is to freeze them. After the leaves have been cut, place them in a bag that is freezer-safe or in an airtight container. Then slide the bags into the freezer.

You can also create a block of parsley by rolling the leaves together into a log. This will allow you to slice it with a knife whenever needed.

You can also dehydrate your parsley by placing washed leaves on trays in a food dehydrator. Or, place them on baking sheets in an oven with temperatures no higher than 170°F.

Once they’re crispy and dried out (it could take anywhere from 1 to 2 hours), you’ll be able to store them for up to three years!

Where to Buy Seeds

Once you’ve decided what type of environment you live in, it’s time to purchase your seeds. Look for reputable sellers online and check reviews from previous customers before making any purchases.

If possible, try to buy organic or heirloom seeds, as these will be free from pesticides and other harmful chemicals.

A good site that we recommend is Seeds Now. They sell high-quality organic seeds.


In the end, companion planting is an incredibly useful practice for enhancing the health of your garden in general.

Consider the benefits before you plant. Choose plants that provide benefits for your parsley, like protection from pests and improved flavor and growth.

With the right combination, your parsley will be healthy and delicious.
