5 Tips to Refresh Spring Containers for Summer
Transform your container garden for summer with expert advice on refreshing your plant arrangements. Here are five key strategies.
1. Refresh the Soil in Your Containers

Before choosing your summer and late summer flowers, evaluate the condition of the potting mix. Experts recommend assessing how long the soil has been in the container.
'Consider whether the soil needs a complete overhaul or if you can simply amend it with fertilizer and worm castings,' advises gardening expert Nicole Dillon. Proper soil health is crucial for successful plant growth, as it provides essential nutrients. If the soil feels compacted and water-resistant, it's time for a fresh potting mix.
Many potting mixes are available online, such as this all-purpose mix from Perfect Plants Nursery. Fertilizers can also boost soil nutrients, like this all-purpose option from Perfect Plant Nursery.

2. Retain Plants that Will Bloom Through Summer

Don't rush to remove all your spring plants; many late-spring flowers can continue thriving into summer.
'Numerous spring container plants can bloom throughout the season,' states gardening expert and botanist Melvin Cubian from PlantIn. 'With proper care, you can grow peace lilies outdoors, lantana, and geraniums well into summer,' he adds.
Other spring blooms like irises and peonies can also extend their blooming period into summer.
It's best to keep any thriving container plants to enjoy their beauty. Just stay diligent with care to prevent common container gardening errors.

3. Remove Spent Annual Bulbs

Consider removing spent annual bulbs that won't bloom again next year, unlike perennial plants like foxgloves and hollyhocks.
'If you're completely changing the soil, remove spent spring annuals from your pots,' advises Nicole. 'If not, prune the top of the plant, leaving the root system intact to promote healthy microbial activity in the soil,' she adds.
Leaving spent bulbs to decompose can be beneficial if space allows. 'Removing the entire plant also takes away beneficial microorganisms that help decompose the root system,' Nicole points out.
Should you choose to remove the bulbs, ensure you have clean and sharp gardening tools. Use something like this Fiskars ergo trowel from Amazon to gently lift the bulbs.
4. Trim Dead Foliage and Flowers

Eliminating dead foliage and flowers will instantly refresh your containers. Look for yellowing leaves and faded blooms, using pruning tools like Fiskars pruning shears from Amazon to cut them back.
'Deadheading blooms encourages new growth and keeps your pots looking fresh,' points out Laura Janney, the owner of The Inspired Garden.
Removing dead plant material redirects energy to healthier stems, often prompting a second bloom cycle. Just be careful to avoid pruning errors to ensure effective rejuvenation.

5. Introduce Summer Blooms

Now is the perfect opportunity to plant summer blooms that you've grown for your pots. Introduce vibrant flowers that thrive in summer heat, adding new colors, shapes, and textures to your arrangements.
Experts recommend selecting plants that fit the location of your pots while considering the thriller, spiller, filler technique—mixing plants of varying heights and forms for a stunning display.
'For dry areas, I'd suggest a small pink muhly grass as the thriller, vinca as the filler, and portulaca as the spiller,' recommends Nicole. 'Both vinca and muhly grass are drought-tolerant, while portulaca features succulent-like foliage and vibrant flowers that bloom until frost,' she adds.
If you have a shaded garden, there are plenty of options as well. 'For shade or semi-shaded spots, consider caladiums or coleus as thrillers, begonias or impatiens for fillers, and creeping jenny as the spiller,' suggests Nicole.
Many spring flowers for shade can also continue to bloom into summer, making them perfect for pots.

When is the Best Time to Change My Spring Containers for Summer?
Experts recommend waiting until the end of spring to transition your containers, allowing your spring plants their time to flourish and ensuring warm temperatures for new summer plants.
'When temperatures rise and the soil consistently exceeds 65°F, it's the right time to swap winter and spring plants for more heat-tolerant varieties,' says gardening expert Nicole Dillon.
'Your plants will also signal when it's time to change. For instance, pansies often stretch toward the light, appearing leggy and scraggly, indicating they're nearing the end of their lifecycle and should be replaced,' she adds.
Enhancing your soil, tidying up your plants, and replacing spring flowers with summer varieties is an effective way to revitalize your spring containers.
