What to Look for When Choosing a Peony Fertilizer?

Peonies grow well when planted and fertilized. Fertilization can play the most important role in the growth of a successful peony garden. Therefore, the selection of fertilizers must be precise. Here are some important facts to remember when buying peony fertilizers:

  • The Fertilizer Must be Suitable for the Long-term Usage

If the fertilizer you are looking for is for growing peonies in containers, use slow-release fertilizers as they release nutrients as the plants grow. Due to their deep roots, peonies consider the pots to be deeper than their plant pots.

Since they still eat a lot of food, consider providing plenty of nitrogen-abundant water, 5-10-10. This should be done in the spring. The reason low nitrogen fertilizers are needed is that you can enjoy early flowering varieties on all peonies.

  • It Should Contain a Small Amount of Nitrogen.

The main reason why you should consider a low nitrogen fertilizer is that your peonies prevent vegetative growth and promote flowering. In this case, the plant grows but produces fewer flowers than pruning.

Nitrogen promotes the growth of all living plants. In addition to promoting the desired growth of plants, it also encourages the growth of unwanted plants around you. When low nitrogen fertilizers are used, there is a risk of unwanted plants and the desired plant absorbs the necessary amount of nutrients.

Another important reason is that the plant is burning. If the plant receives excess nitrogen, there is a high probability that it will burn. This can lead to the death of the plant.

  • Soil Category and Conditions

When choosing a fertilizer, consider the type of soil in which peonies grow. Different types of soil require different amounts of fertilizer, but also for the released capacity or the pH value. If your peonies are in clay soil, use a slow-release fertilizer to prevent nutrients from falling out. On the other hand, if you are using a low pH breakdown, choose a fertilizer that matches the low pH of your peonies this season.

Fertilization Guide - Process for Applying Food for Better Growth and Bloom

  1. It is necessary to put compost or other organic material at the bottom of the peony planting hole. Mixing with up to 1/2 cup of 10-10-10 fertilizer along with 1/2 cup of bone meal or superphosphate also sets the stage for the healthy growth of the peony.
  2. Phosphorus and nitrogen are important nutrients for a peony throughout its life. You need to provide the correct values ​​every year for your plants to grow as they should and produce vibrant flowers. Apply a low nitrogen fertilizer, for example, a 5-10-10 mixture, to the soil around the stem of the peony.
  3. It is important to use a low nitrogen fertilizer for peonies, as a high nitrogen fertilizer can affect the growth of plants. Make sure you don't over-fertilize. Always add fertilizer around the plant's drip line, as adding it directly to the fertilizer crown can burn the plant.
  4.  A 2-3 cm thick layer of organic compost, applied as a cover around the base of the peony, helps maintain moisture and control weeds. The bacteria in the compost break down the organic matter into nutrients necessary for the optimal growth of the plant. When plants begin to grow, it is usually sufficient to use an organic fertilizer, such as 1-1-1, once a year to promote plant growth.
  5. If you plant peonies in 10 to 10 to 10 pots (half a cup) + half a cup of bone meal or superphosphate and mix with organic compost.

When to Fertilize Peonies?

It is better to fertilize or feed your peonies only twice per growing season. The first time you use a fertilizer of your choice, the plant begins to grow and the flowers are the size of beans.

Apply fertilizer to peonies in the spring, when the stems are about 30 cm tall. At this point, the leaves begin to relax. Cold nights must be very rare.

Another telltale sign that it's time to fertilize peonies is that the first flower buds appear. These little flower buds become visible when the stems begin to grow. In the image above, you can see an example of what flower buttons look like for children. Time to feed the peony plants!

Frequent questions

Why are my peonies so small?

Small young shoots are common in young and recently planted peonies. If the problem persists in the soil after more than three years, the two main suspects are lack of sun and / or food. Adding the sun is seldom a garden option, but cutting off some overhanging branches that shade plants this winter can improve your chances of seeing large flowers in late spring.

Why did my peonies dry up?

A common problem with peonies is the inability to open buds in the spring. As a general rule, flower buds grow to the size of a pea and then stop growing. There are several possible causes. In a narrower interpretation, the gem explosion includes only ecological and cultural issues. Generally speaking, the upper burst includes fungal diseases that affect flower buds.

Is bone meal good for peonies?

If you don't know bone meal, it is a mixture of finely ground animal bones and other animal waste. This product generally comes from butchers.

Bone meal is used as a fertilizer for most plants because it slowly releases the necessary phosphorus ingredient. Plants also have their necessary proteins for their growth.

Bone meal can be used as a fertilizer for peonies, as it contains a balanced amount of the nitrogen, phosphorous, and potassium they need.

Are coffee beans good for peonies?

There is a lot of debate about whether the coffee powder is a reliable natural fertilizer for plants. When it comes to peonies, it's best not to spill the ground coffee powder around the peonies and other perennial flowers. The reason for this is that coffee beans are very acidic and should only be used for plants that thrive on acidic fertilizers such as azaleas, rhododendrons, daffodils, and more.

Do peonies bloom more than once?

Peonies bloom once in each ear at a certain time of the year and most of the time in the weather. Many of us have blooming peonies in May and June. Some people who live in warmer climates will have flowers in April, and those in (very) cold climates will have flowers in July. Of course, you can also grow very early varieties to get peonies first or use a refrigerator to store flowers for later use. But few of us saw them bloom in the garden two months after the normal season.

What do you do if the peonies don't bloom?

Flowering failure is generally caused by two things: poor planting and / or insufficient light. When planting peonies, make sure that the eyes (the place where the new growth forms) are no larger than 5 cm. Also make sure your plants receive enough sunlight, 6 hours or more a day. If planted in a shady spot, they will not flower well, if any.

Also note that newly planted peonies don't usually flower in the first year, which is spent developing good root and foliage systems. In the second spring after planting, you will see its first flowers.

Chicken manure good for peonies?

Give your peonies a little chicken fertilizer in the spring and fall, so they bloom beautifully. Bird fertilizers are one of the most widely used non-chemical fertilizers on the market.

Poultry manure is a useful source of nitrogen, the main nutrient that plants need to grow green leaves. It also contains small amounts of other important nutrients.

However, poultry manure is low in nutrients compared to synthetic fertilizers such as growth, as shown below, and releases the nutrient content more slowly, some of which are not available in the soil. in late spring and summer, even if the product is applied in late winter or early spring.
