The best peony fertilizers that will keep your flowers pink and healthy

Which peony fertilizers to buy to keep your flowers thriving throughout the growing season

Peonies are one of the most luscious and beautiful flowers you can grow in your garden, and luckily they’re pretty easy and have an impressive plant hardiness zone range between zones 3 and 8. While you might need to give these plants a little more attention at the extremes of this range, they can still thrive and produce stunning blooms.

There are 33 known species of peonies ranging in size, bloom color, and care needs, so you’re sure to find one that’s right for you and your climate. The Netherlands and Alaska are the two largest cut peony producers in the world. The longer cooler growing season allows these plants to bloom later than in other regions. So don’t be discouraged if you’re in a cooler climate, you’ll probably have the best-looking peony plant on your Instagram feed.

Peonies are considered to be the symbol of wealth and honor and are regarded as omens of good fortune and happy marriages. They can live up to 100 years old and still produce flowers, so if you want to grow a plant that’ll last through generations, this is the plant for you. There is an art to feeding your peonies, though. Ahead, we’ll break down everything you need to know about finding and applying the right peony fertilizer.

The best type of fertilizer for peonies

Although they are tuber plants, peonies will benefit best from a fertilizer made specifically for bulb plants. Bulb fertilizers are optimized for how bulb and tuber plants take in and use nutrients. Perennial fertilizers will also work as long as the ratios are 10-20-20 or 5-10-10. The most important aspect of fertilizing your peony plant properly is to ensure the fertilizer you use doesn’t have too much nitrogen. Too much nitrogen will encourage leafy growth when instead we want to promote blooms on these gorgeous flowering plants.

How to use a peony fertilizer

Now that we’ve gone over what kind of fertilizer your peony plant wants, as well as some of the best options online, let’s talk about how to use that fertilizer to best support your plant for a long healthy life and head-turning blooms.

Peonies should be fertilized twice a season; the first time you fertilize will be early in the spring. Wait until you see shoots coming from the plant. Once the shoots reach about three to six inches in length, you can apply your first round of fertilizer. Do not apply directly to the plant, but rather around the base. Applying the fertilizer to the plant itself can result in burning or even killing your plant. The second time you fertilize, you’ll want to wait until the plant has produced buds that are the size of peas. This will give the plant another boost as it prepares to push out big, luscious flowers.

After that second feeding, your peony plant should be good for the season. However, if you’re noticing signs of stress or the number of flowers you’re getting doesn’t seem right, you can supplement with a bone meal product for strong root growth and flower setting.

Peonies are some of the most famous and beloved flowers on the planet. They’re grown all over the world for their beauty, their history, and their application in medicine. They’re easy to care for, so jump right in and try your hand at growing these stunning flowering plants.

Some vegetables are more suited to be grown in cooler months than others. It all depends on their growing conditions and the kind of environment they prefer. When you’re planting vegetables during winter, the chances are you’re planting them in an insular setting — be it in a greenhouse or in your home. These are a few ideal vegetables to plant in November, but there are many others beyond them if these aren’t up your alley.

Growing rhubarb in containers during the winter is possible, so long as you have a large enough pot to accommodate the plant. With rhubarb, depth is more important than width (depending on how many you want per pot) because of its large root system. You want to make sure you select pots or containers that are sturdy, have good drainage, and are at least twenty inches deep. To the same effect, the soil should be designed for good draining to avoid drowning or rotting the plant. A healthy rhubarb could live and produce for up to ten years if you play your hand right.
