Remove any leaves that will be submerged in water to prevent bacterial growth. When arranging the flowers, start with the focal point blooms like delphiniums and then fill in with smaller flowers and greenery for a balanced look.

Challenges in Growing Delphiniums

Toxicity Awareness

Delphinium plants contain toxic substances, primarily alkaloids, which can be harmful if ingested. It's crucial to understand the toxicity levels of delphiniums to prevent accidents.

When handling delphiniums, always wear gloves to protect your skin from potential irritation caused by the plant's toxins. Avoid touching your face or mouth while working with delphiniums to prevent accidental ingestion.

Educating yourself on the potential risks associated with delphinium toxicity is essential for maintaining a safe gardening environment. Familiarize yourself with common symptoms of poisoning and seek medical help immediately if exposed.

Deer Resistance

To protect delphiniums from deer damage, consider planting them in areas that are less accessible to deer, such as closer to your home or in raised beds. Creating physical barriers like fences can also deter deer from reaching delicate delphinium plants.

Planting deer-resistant companion plants alongside delphiniums can help camouflage them and reduce the likelihood of deer grazing on them. Examples of deer-resistant plants include lavender, daffodils, and foxgloves.

Implementing deterrents like motion-activated sprinklers or applying natural repellents can effectively keep deer away from your garden. These methods create an unpleasant experience for deer without causing harm to the animals.
