Tree peonies require a neutral pH and soil rich in compost for their growth. They cannot tolerate wet feet and prefer a well-draining, rich compost with plenty of organic matter. A balanced fertilizer can be added to the compost before planting the peony for an extra boost.
Peonies do not need ericaceous compost unless you have rich, fertile soil. If your soil is not good, a balanced general fertilizer like Growmore can be applied in the spring. Peonies need a fertile and free-draining growing medium, such as a general-purpose peat-free compost or potting mix mixed with topsoil or loam-based, amended with horticultural grit or perlite. Plants sold in pots are best planted in late spring, while barre-rooted divisions are best planted in late autumn.
Planting peonies in full sun and a fertile, well-drained soil is essential. Herbaceous peonies can be propagated by planting them in fertile, free-draining soil. Tree peonies can handle slightly more acidic soils than herbaceous and should avoid planting in soil with heavy clay that becomes waterlogged unless it has been amended with organic matter like homemade compost or well.
In summary, tree peonies need a neutral pH and well-draining soil, but they do not thrive in peat-based composts. They thrive in most soil types, but additional garden compost can improve structure and water management.

What is the best food for tree peony?
To promote good growth and flowering in shrubs, apply a general-purpose fertiliser like Growmore in spring at 70gm per sq m (2oz per sq yd) and mulch with a 10cm layer of garden compost or well-rotted manure to conserve moisture and suppress weeds. Avoid piling up mulch against stems as they may rot. These glamorous showstoppers produce large blooms in yellow, pink, and maroon in early summer. They need a sheltered spot in light shade with fertile, well-drained soil.
Plant in autumn in a sunny or lightly shaded spot, choose a position sheltered from cold winds, prune out dead stems in late winter, mulch and fertilize in spring, and make new plants by division in autumn.
What type of soil is best for peonies?
Peonies thrive in well-drained, loamy soil, which prevents root rot and fungal diseases. If heavy clay soil is present, amend it with compost, pine bark, or manure to improve drainage and organic matter content. A pH of 6. 5 to 7. 0 is ideal for peonies, which may require lime addition. Peonies are long-lived and require extra care during planting, as they can remain in the same spot for years. Fall planting is recommended, with a hole 12-18 inches deep and 12 inches wide, and roots spread over it. Deep planting can cause failures to bloom. Tree peonies should also be planted in fall, with the graft union an inch below ground level. Extra soil should be mowed around them for the first winter.
Are peonies acid-loving?
Peony plants thrive in slightly acidic soils with good drainage, making them ideal for borders, walkways, and hedges. They are great centerpieces and cut flowers, and some have a delightful fragrance. Planting peonies in fall is recommended, with organic matter added to the soil. Space peonies 90-120 cm apart, and set roots at a depth of 2-3 cm, facing the sky. For early-blooming peonies, wait until fall end and set roots at 1 inch under the soil. Pack the soil tightly around the roots, water well, and check on the plants regularly.
Dividing peonies is not necessary as they don’t like root disturbance. They can be moved or divided if necessary, but they rarely require division. Digging uppeonies is best done after the foliage begins to die back in fall or early spring. Lever the plant out of the ground, shake the plants gently, and locate the buds on the roots. Cut apart the clump with a sharp knife or spade, planting the divisions facing upward, no more than 1-3 cm below the soil surface.
Do peonies need acidic soil?
Peonies require fertile, well-drained soil with a mildly-acid to neutral pH of 6. 5-7 and should not be planted in soggy or standing water areas. They are long-lived and care-free perennials, so it’s crucial to start with vigorous nursery stock and plant in a suitable area. All types of peonies thrive in full sun, with a minimum of 6 hours of sun required for good growth on herbaceous and intersectional peonies. Tree peonies thrive in full sun but have a quick flower fade.

Where do tree peonies grow best?
Tree peonies require a neutral pH and compost-rich soil, as they cannot tolerate wet feet and should be planted in well-draining locations. They prefer dappled light, ideally morning sun and afternoon shade, or dappled sun throughout the day, to prolong the life of their flowers. To prevent flower fading, use wax paper umbrellas and monitor soil moisture. Tree peonies with numerous petals will hold up better in stronger sun.
All peonies need rich soil, good drainage, and a neutral pH. Create a sandy loam soil with equal parts sand, clay, and compost. Avoid planting in low-lying areas that retain water and be cautious when planting near automatic sprinkler or irrigation systems. Plant new tree peonies 5 feet apart on center and 2. 5 feet from any edge or border. Measure the space available for larger gardens.
Can I use ericaceous compost for peonies?
Peonies do not require ericaceous compost and are better adapted to slightly alkaline soils. It is possible to relocate these plants, but it is advisable to wait until they are dormant in late autumn and to lift them with care. It is inadvisable to move the plant frequently, as it will take approximately a year for the roots to re-establish themselves. Peonies are not strictly sun-dependent, although they may not flower as abundantly in shaded conditions. The application of partial shade can assist in the prevention of desiccation.
What is the best fertilizer for tree peonies?
Tree peonies are a popular perennial plant that can be easily found in local garden centers and nurseries. They are responsive to feeding but should not be overfertilized. A complete fertilizer, such as 5-10-5, is recommended as it contains nitrogen, phosphorous, and potassium necessary for growth. Additional bone meal or phosphate can be added to promote strong root development and flower set. Tree peonies are often grouped with herbaceous peonies but can be easily distinguished due to their smaller, glossier leaves.
They can be more expensive, especially new introductions, and can be found generically labeled as “pink” or “red”. Some named varieties to try include “pink” and “red”, and they may not be easily found, so mail order catalogs can be a helpful resource.
How to get more blooms on peonies?
The peony plants appear to be growing well, but there is a lack of phosphorus and potassium in the bloom area. To increase the yield of new buds next spring and more flowers in May, apply 1-2 lbs. of high-phosphorus and potassium fertilizer per 100 sq. feet of garden this fall. To get a soil test, call the extension office in your local county and fill out a form. A soil sample is sent to the lab, and results should be received in about 10 days with an explanation. If you don’t understand the results, reopen an inquiry or ask a question. If you live in Franklin County, call the local extension hotline and speak to a master gardener.
What compost is good for tree peonies?
To plant peonies, dig a hole 30cm deep and wide, add bone meal or general fertilizer like Grow More, and garden compost like rose, tree, and shrub compost. Avoid mixing manure with the soil as it may rot the eyes. Plant peonies in a sunny position for more flowers, but they can thrive in semi-shaded sites with less flowers and longer lifespans. Avoid planting too deeply as it can cause failure. Water sparingly, and if unsure, avoid watering at all. Provide staking for taller varieties in more open sites to maintain their appearance. Overwatering is a common cause of failure.
Do peonies like acidic fertilizer?
Peonies flourish in soil with a neutral to slightly acidic pH range of 6. 5 to 7. 5. A fertilizer that is balanced or specifically formulated for peonies is a superior choice. An understanding of the root structure of peonies is of paramount importance, as it informs the selection of appropriate fertilization methods. Peonies possess a tuberous root system that serves to store nutrients and water for the plant’s utilization.

QUESTION: HI Rosie, I am confused about plant positions. Can you please tell me if the requirement for 6 hours of sunshine for a plant requiring a sunny position, is for sun received in Summer or Winter? I have a bed earmarked for Peonies but Up till late spring the bed is in shade until 11 am and then becomes sunnier as the season goes on and the angle of the sun is higher. Thank you so much 🙂
