What to Do With Peonies in April for Bigger, Better Blooms
Give your peonies the best possible start this April with a few simple steps that lead to stronger growth, healthier plants, and more abundant blooms later in the season
April is when peonies come back to life. Peonies are my favorite flower – I look forward to them every year, and they hold a special place in my heart as the first bouquet my partner ever bought me.
It’s a short but crucial window: what you do now will shape how well your peonies bloom in the weeks ahead. If you want to grow peonies successfully, it helps to know exactly what to do in April.
This guide focuses on herbaceous peonies, the most common type in American gardens, which die back each winter and return ready to burst into life. By following a few simple steps now, you’ll support healthy growth and set your plants up for abundant, beautiful blooms.

Start by giving your peonies a gentle tidy. Brush away any old leaves, leftover mulch, or debris from around the base so the new shoots get plenty of light and air. This simple step not only helps your plants breathe, but it also reduces the risk of fungal problems later on. While you’re at it, pull out any early weeds – peonies don’t like competing for nutrients, especially when they’re just getting started.
'Early spring is the perfect time to clear the base of your peonies,' says Rachel Bull, Head of Gardens at Homes & Gardens. 'It gives the shoots space to grow and sets them up for a healthy, flowering season. Knowing when to plant peonies – or how to care for them in April – really makes a difference to the blooms you’ll enjoy later.'
2. Feed for Stronger Blooms
One of the best things you can do in April is fertilize peonies. Timing is key – apply a balanced, slow-release fertilizer or a layer of compost just as shoots start pushing through the soil. Keep it away from the crown, and you’ll give your plants a boost that leads to bigger buds, stronger stems, and those lush, iconic blooms.
If you want to make it even easier, try a product like Espoma Flower-Tone All-Purpose Fertilizer for a tried-and-true option, or Miracle-Gro Shake ‘N Feed Flowering Plant Food, both from Amazon, for a quick, low-fuss feed.
For gardeners who love a more organic approach, a generous layer of Back to Roots Organic Compost around the base can give your peonies a slow, steady supply of nutrients while enriching the soil for the season ahead.
3. Add Supports Early
Renowned for their generous, bouncy blooms, many peony varieties can quickly become top-heavy without the right support. Knowing how to support peonies is key at this stage, as staking in April helps keep stems upright and ensures the flowers are shown off to their full, elegant effect.
Thankfully, there are a few good options to help. Simple bamboo stakes with garden twine work well, or for a cleaner, more polished look, peony rings or plant frames do the trick. In my own garden, I love using these top-rated Peony Plant Support Rings and Peony Plant Cages – both sturdy and easy to set up.
4. Water Consistently, but Don’t Overdo It
Peonies like a steady level of moisture as they start to grow, but they won’t tolerate soggy soil. If April is dry, give them a good soak now and then rather than little and often.
If it’s been wet, you can largely leave them to it – good drainage matters more than anything.
5. Mulch Lightly (And Carefully)
A light mulch can help hold moisture and keep weeds down, but less is more here. Keep it clear of the crown to avoid trapping moisture where it shouldn’t be. Think of it as a supporting layer, not something to pile on.
The best types of mulch for peonies are compost, leaf mold, straw, or natural wood mulch, such as this organic dye-free premium mulch available at Amazon.
If you want to mulch on a budget, there are several types of mulch you can source for free, including leaves, homemade compost, and wood chips.
6. Keep an Eye on Buds and Pests
By mid to late April, you’ll usually see buds beginning to form, and that’s your signal to keep a closer eye on peony pests and problems. Take a moment to check for aphids or any early signs of disease, especially if the weather turns damp. Catching problems early is often all it takes to keep your peonies healthy and on track.
If you do spot pests, a gentle solution like Safer Brand Insect Killing Soap can quickly bring things back under control without disrupting the plant’s growth.
