Canada Geese: A Nuisance in Your Garden

Introduction

Canada geese are beautiful birds, but they can be a real nuisance in your garden. They eat your plants, leave droppings everywhere, and can even be aggressive. If you’re having problems with Canada geese, there are a few things you can do to get rid of them.

Why Canada Geese Are a Problem

Canada geese are herbivores, which means they eat plants. They are especially fond of嫩嫩的嫩芽, flowers, and fruits. A flock of geese can quickly devastate a garden, eating everything in sight.

In addition to eating your plants, Canada geese also leave behind a lot of droppings. Each goose produces about 14 pounds of droppings per week. This can quickly add up, making your garden a smelly, unsightly mess.

Canada geese can also be aggressive, especially during nesting season. They may attack people or pets who come too close to their nest.

What You Can’t Do About Canada Geese

There are some things you can’t do to get rid of Canada geese because they are protected by law. You can’t:

Capture or kill Canada geese, except as outlined by your state’s hunting regulations.
Disturb a goose that is sitting on a nest or remove or destroy the eggs.
Harass geese once they begin nesting, but you can remove accumulated nesting material before they nest.

What You Can Do About Canada Geese

Even though there are some things you can’t do about Canada geese, there are still a number of things you can do to get rid of them. Here are a few tips:

Erect a barrier. Geese prefer to walk from the water to their feeding area and back. One of the most effective ways to keep geese out of your garden is to erect some type of barrier, such as a 2-foot tall hedge or fence.
Never feed the geese. Feeding geese will only encourage them to come back.
Remove nesting material. In spring, geese begin collecting and stockpiling nesting material. Watch for piles of material on your property and remove them before the geese have a chance to build a nest.
Scare them away. Use noisemakers, barking dogs, or other methods to scare geese away. Be persistent, and the geese will eventually get the message.
Install staking. Place stakes every 20 to 25 feet around a pond and string wire between the stakes at a height of 10 to 12 inches. Canada geese will not nest in an area where they can’t easily walk in and out of the water.

Conclusion

Getting rid of Canada geese can be a challenge, but it’s possible. By following these tips, you can keep geese out of your garden and enjoy your outdoor space in peace.

Downy Mildew: A Common Garden Problem

Downy mildew is a sneaky plant disease that can cause serious damage to your garden. It’s caused by tiny organisms that thrive in cool, wet conditions, and it can affect a wide range of plants, from vegetables to flowers.

What is Downy Mildew?

Downy mildew is not a fungus, like powdery mildew. Instead, it’s caused by parasitic organisms that are more closely related to algae. These organisms need water to survive and spread, so they’re most likely to show up in your garden during the spring, when rainfall is frequent and temperatures are cool.

Symptoms of Downy Mildew

Downy mildew can appear different ways, depending on the type of plant it infects. Some common symptoms include:

A fuzzy, soft growth on the lower leaves of the plant. This growth can be white, gray, brown, or purple, and it’s where the disease gets its name from.
Mottling or spots on the leaves. These spots can be yellow, light green, brown, black, or purple.
Stunted growth or leaf loss.

Controlling Downy Mildew

The best way to control downy mildew is to prevent it from happening in the first place. Here are some tips:

Water your plants from below. This will help prevent water from sitting on the leaves, which gives the downy mildew spores a chance to infect the plant.
Practice good garden hygiene. Remove dead plant material from your garden in the fall, as this can harbor the disease over the winter.
Improve air circulation. This will help to reduce humidity, which can make your plants more susceptible to downy mildew.

Treating Downy Mildew

If your plants do become infected with downy mildew, there are a few things you can do to try to control it:

Remove infected leaves. This will help to prevent the disease from spreading to other parts of the plant.
Use organic controls. There are a number of organic fungicides that can be effective against downy mildew.
Reduce moisture and humidity. This will make it harder for the downy mildew spores to spread.

Long-Term Effects of Downy Mildew

Downy mildew can cause serious damage to your plants, including stunted growth, leaf loss, and even death. In some cases, the disease can also make your plants more susceptible to other pests and diseases.

Tips for Preventing Downy Mildew

Choose resistant plant varieties.
Rotate your crops each year to avoid planting the same plants in the same location year after year.
Water your plants in the morning so that the leaves have time to dry out before nightfall.
Avoid overwatering your plants.
Mulch around your plants to help retain moisture and suppress weeds.
Keep your garden clean and free of debris.

Conclusion

Downy mildew is a common problem in many gardens, but it can be controlled with proper care and attention. By following the tips in this article, you can help to protect your plants from this destructive disease.

Lily Leaf Beetles: Identification, Control, and Prevention

by Gregory October 1, 2021

written by Gregory 3 minutes read

Lily Leaf Beetles: A Guide for Gardeners

Lily leaf beetles are a common pest that can cause significant damage to lilies and other plants in the lily family. These beetles are native to Europe and Asia, but they have been introduced to North America and are now found in many parts of the United States and Canada.

Identifying Lily Leaf Beetles

Adult lily leaf beetles are about 1/2 inch long and have a bright red body with a black head, antennae, and legs. They are good fliers and can quickly spread from plant to plant. The larvae of lily leaf beetles are orange, brown, yellowish, or greenish and have swollen bodies. They carry their excrement on their backs, which gives them a distinctive appearance.

Damage Caused by Lily Leaf Beetles

Lily leaf beetles can cause damage to plants in both their adult and larval stages. Adults feed on the leaves of lilies, chewing holes in the foliage. Larvae feed on the underside of leaves, causing them to turn brown and wilt. Heavy infestations can defoliate plants, stunt their growth, and even kill them.

Controlling Lily Leaf Beetles

There are a number of ways to control lily leaf beetles, including:

Handpicking: Adult lily leaf beetles can be handpicked off of plants and dropped into a bucket of soapy water. The larvae can be removed by hand or by spraying them with a strong stream of water.
Insecticides: There are a number of insecticides that are effective against lily leaf beetles, including neem oil, carbaryl (Sevin), malathion, and imidacloprid. Always read and follow the label directions carefully when using insecticides.
Beneficial insects: Some beneficial insects, such as ladybugs and lacewings, prey on lily leaf beetles. Encouraging these beneficial insects into your garden can help to control lily leaf beetle populations.

Preventing Lily Leaf Beetles

There are a number of things you can do to prevent lily leaf beetles from infesting your garden, including:

Inspect plants carefully before purchasing them. Do not buy plants with holes in the foliage or ragged edges on the leaves.
Check the undersides of leaves for young larvae and egg masses. If you find any, remove them by hand or spray them with a strong stream of water.
Clean up plant debris in the fall. Lily leaf beetles overwinter in the soil and on debris left in the garden. Cleaning up plant debris can help to reduce infestations the following year.
Avoid sharing plants with others. Lily leaf beetles can be spread from plant to plant, so it is important to avoid sharing plants with others who have found them in their gardens.

Additional Tips for Controlling Lily Leaf Beetles

Use row covers to protect young plants from lily leaf beetles. Row covers are a physical barrier that can prevent lily leaf beetles from reaching your plants.
Plant lilies in a sunny location. Lily leaf beetles prefer to feed on plants that are growing in the shade.
Keep your garden clean and free of weeds. Weeds can provide a hiding place for lily leaf beetles.
Companion planting: Planting certain companion plants, such as marigolds and nasturtiums, can help to deter lily leaf beetles.

By following these tips, you can help to control lily leaf beetles in your garden and protect your plants from damage.
