Perennials are beloved for their long-lasting beauty, low maintenance, and seasonal blooms, making them a staple in many gardens. However, not all perennials thrive in containers. Some plants have extensive root systems, require specific soil conditions, or need consistent moisture that pots cannot provide. Growing the wrong perennials in containers can lead to poor growth, weak blooms, and even plant death.

Understanding which perennials are unsuitable for pots—and why—can help gardeners make informed choices and maintain a healthy, thriving garden.

This article explores eight perennials you should never grow in pots, explaining the reasons and providing alternatives for container gardening.

1. Peonies

Why They Don’t Do Well in Pots

Peonies are deep-rooted perennials that can live for decades. Their roots need space to spread and to establish a robust crown. Pots restrict root growth and can dry out quickly in summer.

Effects of Container Growth

• Poor flowering due to restricted root space.
• Increased susceptibility to drought stress and temperature fluctuations.
• Shortened lifespan and reduced vigor.

Alternative

• Plant peonies in the ground with well-draining soil and full sun exposure.
• If you must use containers, choose large, deep pots and accept limited bloom potential.

2. Asparagus (Perennial Vegetable)

Why They Don’t Do Well in Pots

Asparagus produces long-lived crowns and roots that penetrate deeply. Containers cannot accommodate the extensive underground growth required for consistent spear production.

Effects of Container Growth

• Reduced spear yield and plant stress.
• Increased risk of root rot in confined, poorly drained soil.
• Plants may fail to establish over time.

Alternative

• Grow asparagus in raised beds or garden rows for maximum productivity.

3. Daylilies (Hemerocallis)

Why They Don’t Do Well in Pots

Daylilies develop dense, fibrous root systems that can quickly outgrow small containers. While they can survive temporarily in pots, they rarely thrive or flower optimally.

Effects of Container Growth

• Crowded roots reduce water and nutrient absorption.
• Flowers may be smaller or fewer in number.
• Plants require frequent repotting, increasing labor.

Alternative

• Plant daylilies directly in the garden, where roots can expand naturally.
• If container growth is necessary, choose large, wide pots and be prepared for regular maintenance.

4. Hostas

Why They Don’t Do Well in Pots

Hostas are shade-loving perennials that develop broad, spreading roots and rely on consistent soil moisture. In pots, soil dries rapidly, and the root system is often too restricted for full growth.

Effects of Container Growth

• Leaf size and overall plant size are diminished.
• Increased stress from temperature fluctuations and water stress.
• Susceptibility to slugs and pests increases in small containers.

Alternative

• Plant hostas in garden beds with rich, well-draining soil and partial shade.
• If container gardening is desired, larger pots with high organic matter soil are essential.

5. Ferns (Large Varieties)

Why They Don’t Do Well in Pots

Large ferns, such as Ostrich Fern or Cinnamon Fern, require ample root space and consistent moisture. Containers often dry out quickly and do not support their extensive root mass.

Effects of Container Growth

• Wilting, stunted growth, and smaller fronds.
• Increased vulnerability to temperature extremes and drought.
• Frequent repotting needed to prevent root congestion.

Alternative

• Plant large ferns in moist, shaded garden areas with rich soil.

Why They Don’t Do Well in Pots

While some lavender varieties can survive in pots, traditional English lavender struggles in containers because it needs excellent drainage, full sun, and root room. Confined pots retain too much moisture and can lead to root rot.

Effects of Container Growth

• Poor flowering and short-lived plants.
• Root rot due to overwatering or poor drainage.
• Plants require frequent repotting and careful soil management.

Alternative

• Grow lavender in well-drained garden beds with sandy soil and full sun.
• For container growth, select dwarf or compact lavender varieties.

7. Trees and Large Shrubs (Perennial Woody Plants)

Why They Don’t Do Well in Pots

Perennial trees and large shrubs, including lilacs, hydrangeas, and rhododendrons, have extensive root systems. Containers restrict root expansion and create stress due to fluctuating soil moisture and temperature.

Effects of Container Growth

• Poor flowering and slow growth.
• Increased susceptibility to drought, pests, and diseases.
• Need for frequent repotting and root pruning.

Alternative

• Plant large shrubs and trees directly in the ground with adequate spacing and support.
• For container gardening, opt for dwarf or compact cultivars.

8. Bamboo (Clumping and Running Varieties)

Why They Don’t Do Well in Pots

Bamboo has vigorous, spreading root systems. While it can survive temporarily in a container, pots restrict growth and cause stress over time.

Effects of Container Growth

• Root-bound plants with limited nutrient uptake.
• Reduced height and density.
• Frequent maintenance and repotting needed to prevent container overcrowding.

Alternative

• Plant bamboo in garden soil or confined ground spaces with barriers for running types.
• Container-friendly dwarf bamboo varieties are better suited for pots.

General Guidelines for Container-Friendly Perennials

1. Check Root Systems: Plants with deep, spreading roots often struggle in containers.
2. Assess Growth Size: Large perennials need room for above- and below-ground growth.
3. Evaluate Moisture Needs: Plants requiring consistently moist soil may not thrive in rapidly drying pots.
4. Consider Lifespan: Short-lived or delicate perennials may do better in containers.
5. Select Container-Adapted Varieties: Many nurseries sell dwarf or compact cultivars specifically for pots.

Following these guidelines ensures healthy, thriving plants and reduces stress for both gardener and perennial.

Conclusion

While container gardening provides flexibility and mobility, not all perennials are suited for pots. Choosing the wrong plants for containers can result in stunted growth, poor flowering, or plant death. The eight perennials you should generally avoid growing in pots are:

1. Peonies – need deep root space.
2. Asparagus – extensive underground crowns.
3. Daylilies – dense fibrous roots.
4. Hostas – broad spreading roots and high moisture needs.
5. Large Ferns – require consistent moisture and root space.
6. Lavender (English varieties) – sensitive to overwatering in pots.
7. Trees and Large Shrubs – extensive roots and size constraints.
8. Bamboo – aggressive root growth and container stress.

Instead, gardeners should plant these species in garden beds or appropriate outdoor spaces while reserving containers for compact, dwarf, or slow-growing perennials. Making the right choice ensures that your garden is vibrant, healthy, and low-maintenance, allowing your perennials to thrive year after year.

Sunflowers (Helianthus annuus) are among the most beloved garden plants, admired for their towering stems, vibrant yellow petals, and striking seed heads.

Dividing plants is a popular gardening technique to rejuvenate overgrown perennials, increase your plant stock, and improve flowering or fruiting. While division can benefit many species, spring is not the right time for all plants. Dividing at the wrong stage of growth can stress plants, reduce flowering, and even kill them. Understanding which plants should never be divided in spring—and why—is crucial for a healthy garden.

This article explores seven plants you should avoid dividing in spring, explaining the reasons and the best timing for each.

1. Peonies

Why You Shouldn’t Divide in Spring

Peonies are notorious for being slow to establish. Dividing them in spring, when they are just emerging from dormancy, can damage their delicate new shoots and severely reduce blooming for several years.

Effects of Early Division

• Wounded roots may rot if exposed to moisture.
• Reduced or no blooms in the following season.
• Stress on the plant can lead to poor growth and susceptibility to disease.

Best Time to Divide

• Late fall, after the plant has finished flowering and leaves have died back.
• Wait until the plant is fully dormant to minimize shock.

2. Lilies

Why You Shouldn’t Divide in Spring

Lilies produce bulbs that store energy for the growing season. Dividing them in spring can remove energy reserves needed for flowering and leaf development.

Effects of Early Division

• Stunted or delayed blooms.
• Weak root establishment.
• Increased risk of rot in cold, wet spring soil.

Best Time to Divide

• Late summer or early fall, after the foliage has died naturally.
• Bulbs can then establish roots before winter dormancy.

3. Hostas

Why You Shouldn’t Divide in Spring

Hostas emerge from the soil in spring with tender shoots. Dividing too early can easily damage these shoots, reducing vigor and flowering potential.

Effects of Early Division

• Broken crowns or damaged roots.
• Slow recovery and uneven growth.
• Reduced ornamental appeal for the season.

Best Time to Divide

• Late summer or early fall, once foliage is mature.
• Dividing during this period allows roots to establish before the plant enters winter dormancy.

4. Asparagus

Why You Shouldn’t Divide in Spring

Asparagus is a perennial vegetable that sends up delicate spears in spring. Dividing crowns at this stage can disrupt spear production and reduce yields for years.

Effects of Early Division

• Weak spears or reduced harvest.
• Stress on the root system, increasing susceptibility to pests and disease.

Best Time to Divide

• Late fall, when the plant is dormant.
• Allows roots to recover before the next spring growth cycle.

5. Iris (Bearded Iris)

Why You Shouldn’t Divide in Spring

Bearded irises send up new shoots in early spring, and their rhizomes are vulnerable at this stage. Dividing too soon can damage buds and reduce flowering.

Effects of Early Division

• Fewer or no flowers in the upcoming season.
• Increased risk of rot due to exposed rhizomes.

Best Time to Divide

• Late summer, after flowering has finished.
• Dividing then allows rhizomes to settle and produce strong foliage before winter.

6. Bleeding Hearts (Dicentra)

Why You Shouldn’t Divide in Spring

Bleeding hearts produce delicate emerging shoots in spring. Dividing them during active growth can break stems and roots, causing the plant to weaken or die.

Effects of Early Division

• Loss of emerging foliage and flowers.
• Plant may fail to recover in the same season.

Best Time to Divide

• Late summer, after foliage begins to yellow and die back naturally.
• Dividing at dormancy reduces stress and supports healthy regrowth.

7. Ferns

Why You Shouldn’t Divide in Spring

Ferns start producing new fronds in spring, which are tender and easily damaged. Dividing at this time can harm the crown and roots, slowing recovery.

Effects of Early Division

• Broken crowns leading to weak or no fronds.
• Susceptibility to fungal diseases in damp spring conditions.

Best Time to Divide

• Late summer or early fall, when fronds have matured.
• Divisions have time to establish roots before winter dormancy.

General Tips for Dividing Plants Safely

1. Know Your Plant: Always research your plant species’ growth and dormancy cycles.
2. Use Clean Tools: Sterilize knives or spades to prevent disease transmission.
3. Water Before and After: Ensure soil is moist to reduce transplant shock.
4. Avoid Fertilizer Immediately: Wait until plants are well-established after division.
5. Handle Roots Gently: Damaged roots increase stress and recovery time.

Conclusion

While dividing perennials and bulbs is an effective way to rejuvenate plants and propagate new ones, timing is everything. Dividing the wrong plants in spring can lead to reduced blooms, stunted growth, or even plant death.

The seven plants you should never divide in spring are:

1. Peonies – wait until late fall.
2. Lilies – divide after foliage dies in late summer.
3. Hostas – divide late summer or early fall.
4. Asparagus – divide in dormant fall season.
5. Bearded Irises – divide after flowering in late summer.
6. Bleeding Hearts – divide after foliage dies back in late summer.
7. Ferns – divide once fronds are mature in late summer.

Following proper timing ensures that your garden plants thrive, flower abundantly, and maintain strong root systems for years to come. By respecting their natural cycles, you can enjoy a lush, healthy garden without compromising plant vitality.
