What to Do with Poppies After Flowering? 5 Best Practices

by Anna

Poppies are cherished for their vibrant colors and delicate petals, gracing gardens with their beauty during the blooming season. However, once the flowers have faded and the petals have fallen, many gardeners may wonder what steps to take next to ensure the health and longevity of their poppy plants. In this comprehensive guide, we will explore the best practices for managing poppies after flowering, from deadheading to seed collection and beyond.

Understanding Poppies: A Brief Overview

Before delving into post-flowering care, it’s essential to understand the basics of poppy plants. Poppies belong to the Papaveraceae family and encompass a diverse range of species, including the iconic Oriental poppy (Papaver orientale), California poppy (Eschscholzia californica), and Iceland poppy (Papaver nudicaule), among others. These flowering plants are known for their distinctive cup-shaped blooms, which come in an array of colors, including red, pink, orange, yellow, and white.

Poppies typically bloom in late spring to early summer, providing a spectacular display of color in gardens and landscapes. While their flowering period may be relatively short-lived, proper care after blooming can help prolong the plant’s lifespan and ensure a bountiful display in future seasons.

Deadheading: Enhancing Aesthetics and Encouraging Growth

Deadheading, the practice of removing spent flowers from the plant, is a crucial step in poppy maintenance after flowering. Not only does deadheading improve the plant’s aesthetic appeal by tidying up the garden, but it also promotes continued blooming and prevents self-seeding, which can lead to overcrowding.

To deadhead poppies, simply snip off the faded flowers at the base of the stem using clean and sharp gardening shears. Be sure to remove the entire flower head, including any developing seed pods, to prevent self-seeding. Deadheading should be performed regularly throughout the flowering season to encourage the plant to produce new blooms and maintain a neat appearance.

Seed Collection: Harvesting the Fruits of Your Labor

One of the most rewarding aspects of growing poppies is the opportunity to collect and save seeds for future propagation. Poppies produce distinctive seed pods, also known as capsules, which contain numerous tiny seeds. Seed collection should be undertaken once the pods have ripened and turned brown, indicating that the seeds are mature and ready for harvest.

To collect poppy seeds, wait until the seed pods have dried on the plant and begin to rattle when shaken gently. Use scissors or pruners to snip off the seed pods, taking care to avoid damaging the plant. Place the harvested seed pods in a paper bag or envelope and store them in a cool, dry place until you are ready to extract the seeds.

To extract the seeds from the pods, gently crush the dried pods between your fingers, allowing the seeds to spill out. Alternatively, you can shake the pods vigorously inside a paper bag to release the seeds. Once the seeds have been collected, store them in a labeled envelope or container in a cool, dark, and dry location until you are ready to sow them.

Division and Transplanting: Renewing and Refreshing Your Garden

As perennial plants, many varieties of poppies benefit from periodic division and transplanting to rejuvenate the plant and prevent overcrowding. Division involves digging up established poppy plants and dividing them into smaller sections, each with its own roots and foliage. This process not only allows you to propagate new plants but also revitalizes the existing ones, promoting healthier growth and increased flowering.

The best time to divide poppies is in early spring or late summer, when the plants are dormant or experiencing minimal growth. Begin by carefully digging up the entire plant, taking care to preserve as much of the root system as possible. Once the plant has been lifted from the ground, use a sharp knife or garden spade to divide the root ball into smaller sections, ensuring that each division has several healthy shoots and roots.

After dividing the plant, replant the sections in their desired locations, making sure to space them adequately to allow for future growth. Water the newly transplanted divisions thoroughly to help them establish themselves in their new environment. With proper care and attention, divided poppies will quickly take root and begin to thrive, adding beauty and charm to your garden for years to come.

Mulching and Fertilizing: Nourishing Your Poppies for Optimal Growth

Mulching and fertilizing are essential components of poppy care after flowering, helping to replenish nutrients in the soil and maintain optimal growing conditions for the plants. Mulching not only conserves moisture and suppresses weeds but also insulates the soil, protecting the delicate roots of poppies from temperature extremes.

Organic mulches, such as compost, shredded leaves, or bark chips, are ideal for nourishing the soil and improving its structure over time. Apply a layer of mulch around the base of poppy plants, taking care to leave a small gap between the mulch and the stems to prevent rot and fungal diseases. Replenish the mulch as needed throughout the growing season to maintain a consistent depth and coverage.

In addition to mulching, fertilizing can help boost the growth and blooming potential of poppy plants, especially in nutrient-poor soils. Choose a balanced, slow-release fertilizer formulated for flowering plants and apply it according to the manufacturer’s instructions. Avoid over-fertilizing poppies, as excessive nitrogen can lead to lush foliage at the expense of flowers.

Pest and Disease Management: Protecting Your Poppies from Harm

While poppies are relatively low-maintenance plants, they may occasionally fall prey to pests and diseases that can impact their health and vitality. Common pests that may target poppies include aphids, slugs, snails, and flea beetles, which can feed on the foliage and flowers of the plants.

To manage pests effectively, monitor your poppy plants regularly for signs of infestation, such as distorted foliage, yellowing leaves, or the presence of insects. Insecticidal soaps, neem oil, or botanical insecticides can be used to control minor infestations, while physical barriers such as copper tape or diatomaceous earth can deter slugs and snails.

In addition to pests, poppies may be susceptible to fungal diseases such as powdery mildew, downy mildew, and root rot, especially in humid or poorly drained conditions. To prevent fungal infections, avoid overhead watering and ensure good air circulation around the plants. Remove and dispose of any infected plant material promptly to prevent the spread of disease.


In conclusion, caring for poppies after flowering is essential for maintaining the health, vigor, and beauty of these beloved garden plants. From deadheading and seed collection to division and transplanting, each step plays a vital role in ensuring the long-term success of poppies in your garden.

By following the guidelines outlined in this article and providing proper care and attention, you can enjoy a bountiful display of poppies year after year, enhancing the beauty and charm of your garden landscape. Whether you’re a seasoned gardener or a novice enthusiast, cultivating poppies is a rewarding endeavor that offers endless opportunities for creativity, enjoyment, and appreciation of nature’s wonders.
