Top Tips for Tidying Up Perennials in November

1. Cut Back Dead or Diseased Foliage

Start by inspecting your perennials for any dead or diseased foliage. Removing these parts helps prevent diseases from overwintering and ensures healthier growth in the spring.

Tip: Use sharp, clean pruning shears to cut back dead foliage to the ground or to healthy growth. Be sure to dispose of any diseased material away from your garden.

2. Deadhead Spent Flowers

Remove spent flower heads from your perennials to tidy up the garden and encourage new growth. Deadheading prevents the plant from expending energy on seed production, allowing it to focus on root and foliage development.

Tip: Use pruning shears to snip off the spent blooms just above the first set of healthy leaves. This not only keeps the garden looking neat but can also encourage some late-season blooms in certain perennials.

3. Clear Away Debris

As you tidy up your perennials, make sure to clear away fallen leaves, old plant material, and any debris that may have accumulated. This helps reduce the risk of pests and diseases taking hold in your garden.

Tip: Rake up leaves and remove any twigs or dead plant material. Compost healthy debris but discard any diseased material away from your garden.

4. Mulch for Protection

After tidying up, consider applying a layer of mulch around your perennials. Mulch acts as insulation, helps retain soil moisture, and suppresses weeds while protecting the roots during winter.

Tip: Use organic mulch such as shredded leaves, straw, or wood chips, and apply a 2-3 inch layer around the base of your perennials, keeping the mulch a few inches away from the stems to avoid rot.

5. Check for Pests and Diseases

While tidying up, inspect your perennials for any signs of pests or diseases. Look for signs of insect activity, such as holes in leaves or webbing, and address any issues immediately.

Tip: If you find any pests, use organic pest control methods to manage them. This can include insecticidal soap or neem oil, which can help eliminate pests without harming beneficial insects.

6. Divide Overgrown Perennials

November is also a great time to divide any overgrown perennials that are crowding each other. Dividing encourages new growth and can rejuvenate plants that have become too dense.

Tip: Use a spade or garden fork to carefully lift the clump of plants, then separate them into smaller sections. Replant the divisions immediately, ensuring they have enough space to grow.

7. Support Leaning Perennials

If you have any perennials that are leaning or have fallen over, consider staking them or providing support before winter arrives. This helps prevent damage from snow or ice accumulation.

Tip: Use bamboo stakes or garden supports to prop up leaning plants, securing them gently with soft ties. This keeps them upright and reduces the risk of breaking.

8. Water Before Ground Freezes

If your perennials have not received adequate moisture in the fall, consider watering them thoroughly before the ground freezes. This helps hydrate the plants and prepares them for winter.

Tip: Water your perennials deeply, ensuring the moisture penetrates the root zone. This is particularly important for newly planted perennials that need consistent moisture to establish roots.

9. Protect Tender Perennials

If you have tender perennials that may not survive freezing temperatures, consider providing extra protection by covering them with frost cloths or moving potted plants indoors.

Tip: Use frost cloths to cover tender perennials or place them in a sheltered location, such as a garage or unheated greenhouse, to protect them from cold temperatures.

10. Plan for Next Season

As you tidy up your perennials, take some time to plan for next season. Consider any new plants you’d like to add or changes you want to make to your garden layout.

Tip: Keep a garden journal to note any observations from this year, such as which plants thrived and which struggled. This will help inform your planting decisions for next spring.
