What Makes a Good Companion Plant?

Why pay attention to companion plants? A good companion plant is one that offers various benefits to its neighboring plants, such as minimizing pest and disease issues, which helps enhance their growth, health, and overall productivity. Here are some key qualities that make a good companion plant that will help you plant strategically to make the most of your yard or garden space:

Pest Control: Companion plants may repel pests or attract beneficial insects that prey on pests, helping to reduce pest damage without the need for chemical pesticides.

Pollinator Attraction: Plants that attract pollinators such as bees, butterflies, and hummingbirds can improve pollination and fruit set in neighboring plants, leading to higher yields.

Soil Improvement: Some companion plants have deep roots that help break up compacted soil, while others fix nitrogen or add organic matter to the soil, improving soil fertility and structure for neighboring plants.

Complementary Growth Habits: Companion plants with different growth habits, such as tall plants providing shade for shorter ones or ground covers suppressing weeds, can maximize space and resources in the garden.

Disease Resistance: Certain companion plants may emit chemicals or compounds that inhibit the growth of pathogens or pests, reducing the risk of disease in neighboring plants.

Seasonal Considerations: Companion plants that thrive during different seasons can provide continuous benefits throughout the year, such as early bloomers attracting pollinators or cover crops protecting soil during the off-season.

Aesthetic Value: Companion plants with attractive foliage, flowers, or fruits can enhance the visual appeal of the garden while providing practical benefits to neighboring plants.

Parsley Planting and Growing Tips

When to Plant Parsley

Since I live in USDA plant hardiness zone 8 ( you can find our zone here), I can actually plant parsley in the spring and the fall. Here are the guidelines for both spring and fall planting of parsley, and these guidelines are appropriate for USDA plant hardiness zone 7 as well:

For spring planting: Start planting parsley outdoors in early to mid-spring, after the last frost date has passed. Soil temperatures should be around 50°F (10°C) or higher for optimal germination. You can also start parsley indoors from seeds about 6 to 8 weeks before the last frost date and then transplant the seedlings outdoors once they are well-established.

For fall planting: In Zone 8, fall is an excellent time to plant parsley as the cooler temperatures are ideal for germination and growth. Aim to plant parsley in late summer or early fall, about 6 to 8 weeks before the first expected frost date. This allows the parsley to establish before the colder weather sets in, and it will continue to grow throughout the fall and into the winter months.

Guidelines for planting parsley in the colder USDA plant hardiness zones 3-6 are as follows: Plant parsley in the spring after the last frost date has passed. In colder climates, parsley is typically grown as an annual herb.

For warmer zones 9-11, here are the guidelines: Parsley can be planted in the fall for winter harvest or in the spring for a longer growing season. In these zones, parsley may behave as a biennial or even a short-lived perennial, surviving through mild winters.

Where is the Best Place to Plant Parsley?

The best place to plant parsley is in a location that receives partial to full sunlight, ideally getting at least 4-6 hours of sunlight per day. Parsley prefers well-drained soil that is rich in organic matter, with a pH level between 6.0 and 7.0. It’s important to choose a spot with good air circulation to prevent diseases, and avoid planting it in areas prone to strong winds or frost pockets. Additionally, parsley can be grown in containers or raised beds if garden space is limited, as long as they receive adequate sunlight and moisture. If you want to keep the parsley around for a second year, plant the parsley in an area that will not get tilled up at the beginning of the next growing season. I like to put some in the vegetable garden as an annual and some in the zone 8 perennial garden to grow back and produce seed the next year.

What is the Best Fertilizer for Parsley?

The best fertilizer for parsley is a balanced, organic fertilizer with equal parts nitrogen, phosphorus, and potassium (N-P-K). Look for fertilizers labeled as “all-purpose” or “vegetable fertilizer” (the one I use) with an N-P-K ratio of around 10-10-10 or similar. Organic options such as compost, well-rotted manure, or fish emulsion are also excellent choices as they provide essential nutrients while improving soil structure and promoting microbial activity. When fertilizing parsley, apply the fertilizer sparingly and avoid over-fertilizing, as this can lead to excessive foliage growth with reduced flavor intensity.

How Much Water Does Parsley Need?

Parsley prefers consistently moist soil but does not like to be waterlogged. Water parsley deeply whenever the top inch of soil feels dry to the touch, typically about once or twice a week, depending on the weather conditions and soil drainage. Provide enough water to moisten the soil to a depth of 6-8 inches. It’s important to water the soil directly at the base of the plant to avoid wetting the foliage, which can lead to fungal diseases. Additionally, mulching around parsley plants can help retain soil moisture and reduce the frequency of watering. Adjust watering frequency based on environmental conditions such as temperature and rainfall.

Varieties of Parsley and Their Uses

There are several varieties of parsley, each with its own distinct flavor and culinary uses. Here are some common varieties of parsley and their typical uses:

best parsley companion plants curly leaved parsley growing

Curly Leaf Parsley (Petroselinum crispum var. crispum): This is the most common type of parsley with tightly curled, dark green leaves. It’s often used as a garnish due to its decorative appearance. Curly leaf parsley also adds flavor and freshness to salads, soups, stews, and sauces.

Flat Leaf Parsley (Petroselinum crispum var. neapolitanum): Also known as Italian parsley or flat-leaf Italian parsley. It has flat, serrated leaves and a stronger flavor compared to curly leaf parsley. Flat leaf parsley is preferred for cooking as it holds up well to heat and has a more robust flavor. It’s commonly used in Mediterranean, Middle Eastern, and European cuisines, particularly in dishes like tabbouleh, pasta sauces, marinades, and herb blends.

Hamburg Parsley (Petroselinum crispum var. tuberosum): Also known as root parsley or turnip-rooted parsley. Hamburg parsley has a thick, edible root that resembles a small parsnip or turnip. The root has a mild, sweet flavor and is often used in soups, stews, and casseroles, or roasted as a vegetable. The leaves of Hamburg parsley can also be used in cooking, similar to flat-leaf parsley.

Japanese Parsley (Cryptotaenia japonica): Also known as mitsuba or Japanese wild parsley. Mitsuba has flat, serrated leaves similar in appearance to flat-leaf parsley but with a slightly different flavor profile. It has a unique taste with hints of celery, parsley, and cilantro. Mitsuba is commonly used in Japanese cuisine as a garnish for sushi, salads, and noodle dishes, or as an ingredient in soups and stews.

Harvesting Parsley

Parsley may be harvested and used fresh as a garnish or part of a recipe. It may also be harvested and dried. Fresh parsley tends to have a milder flavor compared to dried parsley, so you may need to adjust the amount to suit your taste. The general rule of thumb is that 1 tablespoon of fresh parsley is roughly equivalent to 1 teaspoon of dried parsley. So, if you need 1 tablespoon of dried parsley, you would use about 3 tablespoons of fresh parsley.

If you wish to dry your parsley, you can either use a food dryer (dehydrator) or an oven. I am fortunate to have a food dehydrator, which I enjoy using to dry garden produce. Here are the simple steps to drying parsley in a food dryer:

Harvest and Wash: Start by harvesting fresh parsley from your garden or purchasing it from the store. Wash the parsley under cold water to remove any dirt or debris.

Prepare the Leaves: Remove the parsley leaves from the stems, discarding any yellowed or damaged leaves. Try to keep the leaves as whole as possible, as smaller pieces may dry out too quickly or become brittle.

Preheat the Dehydrator: Preheat your food dehydrator according to the manufacturer’s instructions. Most food dehydrators (mine included) have temperature settings between 95°F and 125°F (35°C and 52°C), which is ideal for drying herbs.

Arrange on Trays: Arrange the parsley leaves in a single layer on the trays of the food dehydrator. Make sure there is some space between the leaves to allow for air circulation.

Dry: Place the trays in the food dehydrator and set the timer according to the manufacturer’s instructions. Drying parsley typically takes between 1 to 4 hours, depending on the humidity levels and thickness of the leaves. Check the parsley periodically to ensure it is drying evenly.

Check for Dryness: To test if the parsley is dry, remove a leaf from the dehydrator and allow it to cool for a few seconds. If the leaf crumbles easily between your fingers, it is dry and ready to be stored. If it feels leathery or retains moisture, continue drying for another hour and test again.

Cool and Store: Once the parsley is completely dry, remove it from the dehydrator and allow it to cool to room temperature. Store the dried parsley in an airtight container, away from light and moisture, to maintain its flavor and freshness. I often store home dried produce in the freezer to make sure it retains its quality.

No food dryer? No problem! Here’s how to dry parsley in an oven:

Preheat the Oven: Preheat your oven to its lowest setting. This is typically (as is mine) around 170°F (75°C), but some ovens may have a “warm” setting that’s even lower. 

Prepare the Parsley: Wash the parsley under cold water to remove any dirt or debris. Pat the leaves dry with a clean kitchen towel or paper towels. Remove the leaves from the stems and discard any yellowed or damaged leaves.

Arrange on Baking Sheets: Line baking sheets with parchment paper or silicone baking mats. Arrange the parsley leaves in a single layer on the baking sheets, making sure there is some space between the leaves to allow for air circulation.

Dry in the Oven: Place the baking sheets in the preheated oven and prop the oven door open slightly to allow moisture to escape. This helps prevent the parsley from steaming instead of drying. Depending on the thickness of the leaves and the humidity levels, drying parsley in the oven can take anywhere from 1 to 3 hours.

Check for Dryness: After about an hour, check the parsley to see if it’s drying evenly. Rotate the baking sheets if necessary to ensure even drying. Continue drying until the parsley leaves are crisp and crumble easily between your fingers.

Cool and Store: Once the parsley is completely dry, remove it from the oven and allow it to cool to room temperature. Once cooled, store the dried parsley in an airtight container, just as you would with the parsley dried in the food dryer.
