Beneficial Insects for Your Garden Q&A

Q: Will all beneficial insects stay in my garden permanently?

Not always. Many beneficial insects are mobile and will move around searching for food, mates, or shelter. However, you can encourage them to stay by planting a continuous succession of blooming plants, offering water and habitat, and avoiding disturbances like over-tilling or spraying chemicals.

Q: Are beneficial insects safe to have around children and pets?

Yes, most beneficial insects are completely harmless to humans and animals. Insects like ladybugs, lacewings, hoverflies, fireflies, and predatory mites do not sting or bite. Even bees and parasitic wasps are generally non-aggressive and only sting when provoked. With proper respect and limited disturbance, they are safe to have in family gardens.

Q: How do I attract beneficial insects to my garden naturally?

You can attract beneficial insects by planting a wide range of pollen- and nectar-rich flowers, especially native species. Herbs like dill, fennel, parsley, coriander, and flowering plants like alyssum, sunflowers, yarrow, and marigolds are particularly effective. Avoid using chemical pesticides, as they can kill helpful insects. Providing water sources and undisturbed shelter, like leaf litter or mulch, also encourages them to stay.

Q: Do I need to buy beneficial insects, or will they come on their own?

While you can purchase beneficial insects (like ladybugs or predatory mites) online or at garden centers, many will naturally find your garden if the environment is right. Planting insect-friendly flowers, reducing pesticide use, and providing habitat can encourage them to come and reproduce on their own.

Q: What’s the difference between beneficial insects and neutral insects?

Beneficial insects directly help your garden by controlling pests or pollinating plants. Neutral insects don’t harm or help—they’re simply present in the ecosystem. It’s important to learn to identify both so you don’t accidentally eliminate harmless or helpful species.

Q: Can I have both bees and children or pets in the same garden safely?

Absolutely. Bees, including honeybees and native bees, are gentle and non-aggressive when left undisturbed. They typically only sting in self-defense, such as when their hive is threatened. Educating children not to swat or disturb bees and planting flowers away from play areas helps ensure a peaceful coexistence.

How To Get Rid Of Snails In Your Garden Q&A

Can I use salt to kill snails in my garden?

Although salt can kill snails by dehydrating them, it is not recommended for garden use. Salt can damage the soil, harm plant roots, and affect beneficial soil organisms. It’s best to stick to safer alternatives like diatomaceous earth, beer traps, and crushed eggshells that target snails without harming your garden’s ecosystem.

Are coffee grounds safe to use for pest control?

Yes, coffee grounds are a popular natural method to deter slugs and snails. The texture and caffeine content are unpleasant to these pests. They’re generally safe for most plants and can even enrich the soil with nutrients. However, they may increase soil acidity, so use them in moderation around plants that prefer neutral or alkaline soil.

Do snails and slugs harm all types of plants?

Snails and slugs prefer soft, tender vegetation, especially young seedlings, lettuce, spinach, basil, and strawberries. However, if populations are high, they may begin feeding on a broader range of plants, including root vegetables and even woody stems. Slugs eat a variety of plant tissues and can devastate a garden if left unchecked.

How do copper barriers work against snails?

Copper reacts with the slime that snails and slugs produce, causing a mild electric shock that repels them. This won’t harm the pests, but they will avoid crossing copper surfaces. Copper tape can be wrapped around planters, garden beds, and containers to form a safe and effective barrier.

Can I keep slugs and snails out of a vegetable garden without chemicals?

Absolutely. Many gardeners successfully keep slugs and snails away using natural methods like handpicking, setting traps, spreading crushed eggshells or coffee grounds, and using copper tape. Additionally, improving garden drainage and watering in the morning will make your vegetable garden less attractive to these pests.

Plants That Attract Dragonflies Q&A

Q: Do I need a big pond for dragonflies?

No—small container ponds with a few aquatic plants can still attract dragonflies and support larvae development, saving space while achieving great results.

Q: Will these plants eliminate all mosquitoes?

While no single solution fully removes mosquitoes, combining dragonfly habitat with standing water management and these plants can significantly reduce mosquito populations.

Q: Are these plants all native?

Most—like swamp milkweed, arrowhead, and blue flag iris—are native and ecosystem-friendly. Always check local rules, especially before planting aggressive species like cattails.

Soil

These plants thrive in well-draining soil. It's essential to ensure that not too much water is retained, as this can lead to root rot. A mix that includes sand or perlite can help improve drainage. Make sure that the pH is between 6.0 and 7.5 for best results.

Water

While they are relatively drought-resistant, they do require regular watering, especially during the first few days. Once established, you can reduce the frequency, allowing for sufficient drying in between watering sessions.

Temperature and Humidity

These plants prefer warmer temperatures (65-85°F) and can tolerate dry conditions. They do best in mild climates and can handle a bit of neglect when it comes to humidity.

Sunlight

They love sunlight! Place them in a spot where they can receive plenty of direct sunlight throughout the day (approximately 6 to 8 hours). If they're indoors, a sunny window will work well.

Location

These plants are versatile and can thrive in various settings. They look great in hanging baskets, containers, or even as ground cover in garden beds. Their trailing stems make them an excellent choice for adding elegance to any area.

Maintenance Tips

Fertilizer

Licorice plants generally don't need heavy feeding. Use a balanced, slow-release fertilizer once in the spring to give them a good start. Avoid over-fertilizing, as this can lead to leggy growth.

Pruning

Pruning is essential to maintain the shape and encourage healthy growth. Trim back any leggy or overgrown stems to keep the plant looking tidy. Pruning also helps promote fuller growth.

Mulching

Adding a layer of mulch around the base helps retain moisture and keep the ground temperature stable. Organic mulch, such as bark or compost, works well and also adds nutrients to the ground as it decomposes.

Potting and Repotting

If you're using containers, choose a pot that is large enough to accommodate their roots. Repot them every couple of years or when you notice the plant becoming root-bound. When repotting, use fresh potting mix to provide new nutrients.

Overwintering

In colder regions, licorice plants may not survive the winter outdoors. If you live in a colder climate, consider bringing your potted plants indoors before the first frost. Keep them in a cool, bright location and reduce watering to keep them healthy through the winter months.

Common Pests and Diseases

Pests

  • Aphids: These small, sap-sucking insects can cause foliage to curl and become distorted. To get rid of aphids, spray the plant with a mixture of diluted down dish soap. Ladybugs, a natural predator of aphids, can also be introduced to control the population.
  • Spider Mites: These tiny pests are hard to see but can cause foliage to look speckled or bronzed. If you suspect spider mites, spray the plant with moisture to knock them off and increase humidity around the plant. Insecticidal soap or neem oil can also be effective.
  • Whiteflies: These small insects can cause yellowing foliage and a sticky substance on the plant. Use yellow sticky traps to capture whiteflies and spray the plant with insecticidal soap if the infestation is severe.

Diseases

  • Root Rot: This occurs when the ground is too wet and poorly draining, leading to the roots rotting. To prevent root rot, make sure the plant is in well-draining ground and avoid overwatering. If you notice yellowing parts and a rotten smell from the ground, remove the affected plant, trim off the rotten roots, and replant in fresh, dry ground.
  • Powdery Mildew: This fungal disease appears as a powdery coating. To treat powdery mildew, remove any affected parts and improve air circulation around the plant. A solution of diluted baking soda can also manage the spread.

How to Harvest Licorice

Gathering licorice is simple and rewarding. Wait until your licorice plants are well-established, typically in their second year of development. Choose a sunny day to gather. Carefully dig around the base of the plant to uncover the roots, while being careful not to damage them. Once you've exposed the roots, cut off sections as needed, leaving some roots intact so the plant can continue to thrive. Clean the gathered roots thoroughly and let them dry before use. This method ensures you get the most out of your licorice plants while allowing them to thrive year after year.

Frequently Asked Questions

Q: How often should I water my licorice?

A: Licorice does best when the ground is allowed to become slightly arid between moisture applications. In the early stages of development, keep the ground consistently moist. Once established, dampen less frequently, providing a deep soaking when the top inch of ground feels arid to the touch. It is also helpful to note that the licorice plant benefits from well-draining soil, adequate sunlight, and occasional pruning to maintain its shape and encourage new growth.

Q: What type of soil is best for licorice?

A: Licorice thrives in well-draining ground with good aeration. A sandy or loamy mix with organic matter works well. Avoid heavy clay ground that retains too much moisture, as they can lead to root problems.

Q: Can licorice be placed indoors?

A: Yes, it can be successfully nurtured indoors as long as it receives plenty of light. Place it near a bright window where it can get at least six hours of sunlight each day. Use a well-draining potting mix and ensure the container has drainage holes to prevent moisture from accumulating.
