How To Fertilize Tree Peonies？

How To Fertilize Tree Peonies？

1.Fertilization Season

  The season of fertilization for tree peonies should be determined based on their growth cycle and physiological characteristics. Generally speaking, fertilization is required 3-4 times a year, with key periods including spring, summer, autumn, and before winter.

  Spring: 

  March to May is the peak season for tree peony growth, and the first fertilization should be carried out at this time. Fertilization in spring helps promote new shoot growth and flower bud formation.

  Summer:

  From June to July, tree peonies enter a critical period for bud formation and growth. At this time, the amount of fertilizer should be appropriately increased, mainly phosphorus and potassium fertilizers.

  Autumn: 

  September to October is the period of bud differentiation and nutrient accumulation for tree peonies. Fertilization during this time helps with bud differentiation and flower opening, while also preparing tree peonies for winter.

  Before winter: 

  Before the tree peony enters its dormant period, apply fertilizer once to enhance its cold resistance and lay a good foundation for its growth in the following year.

  2.Types of fertilizers

  When fertilizing tree peonies, appropriate types of fertilizers should be selected to meet their growth needs.

  Organic fertilizers: 

   Such as decomposed animal manure, plant residues, cake fertilizers, etc. Organic fertilizers contain abundant nutrients such as nitrogen, phosphorus, and potassium, which are very beneficial for the growth of tree peonies. However, when using it, it is important to note that unripe fertilizers can cause damage to tree peonies, so it is necessary to ensure that the fertilizers are fully decomposed.

  Fertilizer:

  Such as potassium dihydrogen phosphate, urea, etc. Fertilizer contains a single nutrient component, so it is important to pay attention to the ratio and dosage when using it to avoid excessive use that can cause damage to tree peonies.

  Compound fertilizer: 

  Compound fertilizer contains various nutrients that can meet the needs of tree peony growth. When fertilizing in autumn, compound fertilizers can be used in moderation.

  3.Fertilization method

  The fertilization methods for tree peonies include root fertilization, foliar fertilization, etc.

  Root Fertilization: 

  Spread fertilizer evenly around the roots of tree peonies, then water to dissolve and penetrate into the soil. Be careful not to let the fertilizer directly contact the roots to avoid burns.

  Leaf fertilization: 

  Dissolve the fertilizer in water, and then spray the fertilizer solution on the leaves of tree peony with a spray. Foliar fertilization can quickly supplement nutrients and promote photosynthesis in leaves. However, it should be noted that the concentration of foliar fertilization should not be too high to avoid damage to the leaves.

  4.Precautions

  Moderate Fertilization: 

  Fertilization should be done in moderation, without excessive use, to avoid damage to tree peonies. At the same time, do not fertilize too little to avoid affecting the growth and flowering of tree peonies.

  Avoid excessive watering: 

  Excessive watering can make the soil too wet, affecting the normal respiration and nutrient absorption of tree peonies, thereby affecting their growth and flowering. It is recommended to control the frequency and amount of watering appropriately.

  Pay attention to the timing of fertilization: 

  The timing of fertilization varies in different seasons, and it is necessary to arrange the fertilization time reasonably according to the season to avoid fertilizing too early or too late. Meanwhile, it is important to avoid fertilizing at high or low temperatures to prevent harm to tree peonies.

  Pay attention to fertilizer quality: 

Choosing high-quality fertilizers can ensure sufficient, safe, and effective nutrients. Do not use expired or spoiled fertilizers to avoid damage to tree peonies.

  In summary, the fertilization of tree peonies requires mastering the correct timing of fertilization, selecting appropriate fertilizer types and methods, and paying attention to details such as fertilizer amount, fertilizer quality, and watering. Reasonable fertilization management can promote the healthy growth of tree peonies and enhance their ornamental value.
