It’s Time To Plant Pansies!

Pansies are the colorful flowers with “faces.” A cool-weather favorite, pansies are great for both spring and fall gardens! Here’s how to plant pansies as well as keep them growing and blooming.

Pansies have heart-shaped, overlapping petals and one of the widest ranges of bright, pretty colors and patterns.

Good for containers, borders, and as ground cover, they are a go-to flower for reliable color almost year-round. Pansies look pretty on their own in a monochrome scheme or in mixed colors; they also look pretty when planted with other cool-season flowers such as violas, primroses, trailing lobelia, and sweet alyssum.

ARE PANSIES ANNUAL OR PERENNIAL FLOWERS? 

The pansy may be treated as either an annual or a perennial, depending on your climate. However, most gardeners treat this plant as an annual because it prefers cool weather and gets too leggy in the heat of summer. There hasn’t been much success in producing heat-tolerant pansies that can adequately survive hot weather.

Pansies are surprisingly hearty in cold weather, though. They’ll survive a frost, bouncing back from even single digit temperatures. If the blooms wither in the cold, the plants will often stay alive to bloom again, which makes them a great flowering plant for fall and early winter color.

PLANTING

WHEN TO PLANT PANSIES

  • Pansies can be planted in the early spring or the fall. 
  • Pansies can be finicky to start from seed; it’s a lot easier to buy established plants from a local nursery. Plus, you’ll get blooms a lot sooner.
  • But if you want to seed, start pansy seeds indoors in late winter 8 to 10 weeks before the last spring frost for early spring and summer flowering. Or, start seeds in late summer for fall and winter flowering. Pansy seeds may be slow to germinate (typically emerging in anywhere from 1 to 3 weeks, depending on soil temperature).
  • Set pansy plants in the ground when it becomes workable in the spring. They grow best when soil temperatures are between 45°F and 65°F (7°C and 18°C).
  • Pansies can tolerate a light frost just after planting, but try to hold off on putting them in the ground if temperatures are still regularly reaching well below freezing.

WHERE TO PLANT PANSIES

  • Plant in moist, humus-rich, well-drained soil. See our articles on soil amendments and preparing soil for planting for more information. 
  • Pansies like full or partial sun, but need cooler temperatures to thrive. The ideal planting site will get morning sun but avoid the heat of the late afternoon.
  • Space the plants about 7 to 12 inches apart. They will spread about 9 to 12 inches and grow to be about 6 to 9 inches tall.

Pansies in Pots

  • Pansies are great for containers. Just use potting soil.
  • Plant in portable containers (12 inches or less in diameter) so the plants can be moved to a cooler area when the sun starts to get stronger. Early in the spring season or in the fall, a south-facing patio might be the perfect spot. During the summer, move pansies to the east side of your home for morning sun and afternoon shade.

CARE

HOW TO CARE FOR PANSIES

  • Remember to water pansies regularly. One of the most common reasons pansies fail is because they are not watered enough, so if your pansies are not doing well, try watering them more.
  • You can use a general, all-purpose fertilizer around your pansies to help them grow. Be wary of using a nitrogen-heavy fertilizer, though, as this can result in more foliage instead of flowers.
  • Remove faded/dead flowers to encourage the plants to produce more blooms and to prolong the blooming season.

10 Essential Spring Gardening Tasks

1. Time for a spring inspection.

On one of the first warm days of spring, put on your inspector’s hat and head out to the garden with a notepad. It’s time to see what happened in the garden while you were indoors all winter. Take note of:

  • Cold, ice or snow damage on plants
  • Beds that will need to be cleaned out
  • Hardscaping elements—walls, fences, benches, sheds, trellises—that have shifted, bowed or rotted
  • Evidence of new animal burrows from skunks, chipmunks, moles and voles, groundhogs or rabbits. Also, note any deer or rodent damage on woody plants.

 

2. Address hardscaping issues first.

In early spring before the ground is ready to be worked, focus your energy on hardscaping. This is the time to repair damaged retaining walls, level out your stepping stones, clean out your gutters, and fix fences, benches, decks, sheds, trellises, window boxes and raised beds. These tasks are easier to accomplish while your plants are still resting safely dormant.

Early spring is also a good time to plan for and build new raised gardens, widen existing ones, and tidy up your beds’ edging. When temperatures allow, add a fresh coat of paint, stain or sealant to any hardscaping elements made of wood.

 

3. Do a thorough spring cleanup.

Ideally just before your spring bulbs start to pop up, clean the plant debris out of your garden beds. This includes fallen branches, matted down leaves, last year’s perennial foliage, ornamental grasses and perennial hibiscus, and any annuals you didn’t remove last fall. Maintaining good hygiene in your garden beds will help to keep pests and diseases at bay.

Now is also a good time to clean out debris from your pond or water feature. While you’re at it, scrub and sterilize your bird bath and containers before setting them back out into the garden. A 1 part bleach/5 parts water solution should take care of any lingering diseases or insect eggs in your containers.    

 

4. Test your garden soil.

Experts recommend testing your garden soil every 3-5 years to see what nutrients or organic materials it needs and which it has too much of. You might learn, for example, that your soil is very high in phosphorous, so you would avoid adding fertilizers that contain a lot of it. Or you might find out your soil is naturally alkaline, and need to add aluminum sulfate around your evergreens and acid-loving shrubs like hydrangeas. Detailed instructions on how to collect and submit your soil sample is available on your state’s Extension Service website.    

 

5. Feed your soil.

Once you know what your garden soil needs based on your test results, talk with someone at your local garden center about which specific products to use, always following package instructions for best results.

A good general practice is to topdress the soil with an inch or two of compost, humus and/or manure in early spring just before or as your bulbs are starting to emerge. That’s also a good time to sprinkle an organic slow release plant food like Espoma’s Plant-tone or Rose-tone around your perennials and shrubs. Earthworms and other garden creatures will do the job of working these organic materials down into the soil for you.

 

6. Get out a sharp pair of pruners.

Spring is a good time to prune some kinds of woody shrubs and trees. We’ve created a detailed guide for you to follow here: Pruning Demystified. Here are a few highlights:

  • Start by pruning out anything that has been broken or damaged by winter ice, snow and cold. Remove dead wood, too. 
  • Follow the general rule that flowering shrubs which bloom on new wood (this year’s growth) can be trimmed in spring. This includes summer flowering shrubs like butterfly bushsmooth hydrangea (H. arborescens)panicle hydrangea (H. paniculata)potentillarose of Sharon, and roses. Their flower buds will be set on the new flush of growth that appears after you prune it.
  • Spring is also a good time to shear back evergreens like boxwood and arborvitae once their initial flush of new growth has finished emerging.
  • DO NOT prune early flowering shrubs and those that bloom on old wood (last year’s stems) like azaleaforsythialilacquinceninebark and weigela in spring. If you do, you’ll risk cutting off this year’s flower buds. You might not be able to see them, but they are there, so resist the urge to prune.    

 

7. Divide perennials and transplant shrubs.

In early spring when they are just beginning to pop up, divide and transplant any perennials that have outgrown their space or grown large enough to split, if desired. In most cases, it’s best to divide and move perennials in the opposite season of when they bloom. That means moving summer and fall blooming perennials in spring, and spring blooming perennials in fall. This avoids disrupting their bloom cycle.

Evergreen shrubs can be moved in early spring before their new growth appears or in early fall to give them enough time to re-establish their roots before winter. Deciduous shrubs can be moved almost anytime they are not in bloom and the weather is mild, but generally spring and fall are the preferred seasons for transplanting. If you move them while they are dormant, there will be less stress on the plants and they will be more likely to spring back into action quickly.     

 

8. Put out any necessary supports like trellises and stakes.

If you’ve brought a trellis into the garage or shed for winter, early spring is a good time to bring it back out into the garden. Make sure it’s sturdy and apply a fresh coat of paint if needed before using it again. If you grow peonies, delphiniums, or any other perennials that require support, set them out now or get them ready to go. Trying to wrangle tender peony stems into a peony ring is tough work once their leaves have unfurled.

 

9. Plant your spring containers and borders.

Though most annual flowers need the soil to warm up a bit before planting, some cool weather loving plants like pansiesnemesia, and osteospermum daisies won’t mind if you plant them in the garden early. Fill your spring containers with sweet alyssumlobelia and Supertunia petunias, too. You’ll find six solutions for cool weather plantings in this article. For most other annuals, it’s a good idea to wait until your area’s last frost date to plant. Your local Extension Service website lists that date on their website.  

 

10. Be ready to take cover if freezing temperatures are in the forecast.

If you garden in an area where late spring frosts and freezes are a possibility, be prepared to cover up plants that have tender emerging buds or foliage if freezing temps are in the forecast. If the buds haven’t begun to open yet, there’s no need to cover them.

Old sheets and towels that have been relegated to the rag pile are a good option, and professional row cover is available for purchase, too. DO NOT cover tender plants with plastic sheeting or tarps. The effect of the plastic touching the newly emerging buds and foliage will magnify the cold’s effect, rather than mitigate it.
