FAQs

When planting Peony ‘Alexander Fleming’ tubers (which are actually bare-root divisions rather than true tubers), it is best to plant one root division per planting hole. Each division will develop into a single, long-living peony plant that needs space to grow. Crowding multiple roots together in one hole is not recommended because peonies dislike competition for nutrients, water, and airflow. For a fuller garden display, you can plant multiple individual roots, but space them about 60–90 cm (24–36 inches) apart. This spacing allows each plant to develop a strong root system and produce large, healthy blooms. Planting too many together can lead to weak flowering, increased risk of disease, and stunted growth. For best results, think in terms of “one strong plant per spot” rather than clustering several roots together. This ensures your Peony ‘Alexander Fleming’ grows vigorously and produces its signature fragrant, double red flowers for decades.

Yes, Peony ‘Alexander Fleming’ plants can gradually multiply over time, but not in the fast spreading way of bulbs like tulips or daffodils. Instead, peonies expand slowly through underground root development and the natural formation of additional buds on the crown. Over several years, a mature plant may become larger and form a thicker clump. However, visible “multiplication” is quite slow and typically takes 3–5 years or more before you notice significant expansion. Gardeners often propagate peonies by carefully dividing mature clumps, usually after 8–10 years of growth, to create new plants. This is the most reliable way to increase your stock of Peony ‘Alexander Fleming’. It’s important not to disturb peonies too often, as they prefer to stay in one place and can take time to recover after division. Overall, they are long-term perennials that slowly increase in size and beauty rather than rapidly spreading across the garden.

Soaking Peony ‘Alexander Fleming’ roots before planting is generally not necessary and is often not recommended. Peony roots are naturally hardy and can absorb moisture directly from the soil once planted. However, if the roots appear very dry after storage or transport, you may briefly soak them for 30 minutes to 1 hour in lukewarm water just to rehydrate them slightly. Avoid long soaking periods, as this can make the roots overly soft and increase the risk of rot once planted. Instead of soaking, it is more important to prepare the planting site properly with well-draining soil and to plant the crown at the correct depth (about 3–5 cm below the soil surface). After planting, watering thoroughly is enough to help the roots settle in. In summary, soaking is optional and only useful in cases of extreme dryness, but proper soil preparation is far more important for successful growth.

Yes, you can grow Peony ‘Alexander Fleming’ in pots or containers, but it requires careful planning because peonies prefer to establish deep, strong root systems. To succeed, choose a large, deep container—at least 30–40 cm (12–16 inches) deep and wide, with excellent drainage holes. The plant should still be positioned so that the eyes (growth buds) are no more than 3–5 cm below the soil surface, even in a pot. Use a rich but well-draining potting mix, ideally blended with compost and a small amount of grit to prevent waterlogging. Container-grown peonies need consistent moisture but should never sit in soggy soil. They also benefit from full sun, at least 6 hours per day, to encourage strong flowering. Keep in mind that potted peonies may need more frequent feeding and occasional repotting every few years. While they can thrive in containers, they generally perform best when planted in the ground long-term.
