Fertilize trees in spring

In spring, trees awaken from their winter dormancy and begin a new growing season. They start to develop leaves and blossoms and produce new shoots.

During this time, a significant portion of a tree's development is determined for the entire annual cycle. If your tree experiences a deficiency here, it will affect the entire growing season. Therefore, spring is considered the most important time to fertilize trees. 

In addition to good nutrient supply, the topic is also important. Water and irrigation in spring are important.

Why trees should be fertilized in spring

In spring, after the winter break, the need for nutrients increases significantly. Good fertilization in spring can:

• promote bud break and leaf growth
• support flower formation
• improve fruit development
• strengthen the tree's resilience
• activate soil life

Furthermore, winter often leaves clear traces in the soil. Frost and precipitation can compact the soil, microorganisms are less active, and nutrients can be leached out.

Spring fertilization therefore benefits not only the tree itself, but also the soil as a living ecosystem. Therefore, we recommend the use of organic fertilizer. Suitable examples include:

• compost
• Worm compost
• organic tree fertilizer
• Mulch made from leaves or wood material

These materials are gradually decomposed by microorganisms in the soil. The nutrients they contain are then available to the tree over a longer period. At the same time, they promote soil life and improve the soil structure.

Fertilizer is especially important for young trees

Young trees particularly benefit from fertilization in spring. Their root system is not yet fully developed, so they depend on nutrients in their immediate surroundings. A balanced spring fertilization helps young trees:

• to grow faster
• to develop stable shoots
• to build a healthy root system

Especially in the first few years, a good supply of nutrients determines how a tree will develop.

Fertilize fruit trees in spring

Fruit trees also have an increased need for nutrients in spring. Fertilizing can be particularly worthwhile if you want to enjoy a good harvest for many years.

Here too, make sure to use organic fertilizer enriched with microorganisms whenever possible. Too much nitrogen can cause the tree to invest more energy in shoot growth and less in fruit production.

The right time for spring fertilization

The ideal time for fertilizing is usually between March and April. At this time, many trees begin to develop their blossoms and the soil begins to warm up. Important is:

• The ground should not be frozen.
• The fertilizer should not be applied to snow or ice.
• Those who want to be absolutely sure should look to the so-called Ice Saints in May. After these late frost days, the risk of ground frost is usually completely over.

Fertilizing and watering go hand in hand

For the fertilizer to be effective, the soil needs sufficient moisture. Water helps to dissolve the nutrients in the soil and make them available to the roots.

Especially in spring, it can be useful to fertilize the tree after fertilizing. Water in a targeted manner. This allows nutrients to reach the root zone more effectively. We also recommend the article on this topic. Water trees in spring.

The Baumbad liquid fertilizer based on high-quality Worm compost, which natural excrement of earthworms. It contains a wealth of living microorganisms, humic acids, plant-available nutrients and growth-promoting enzymes. The Baumbad liquid fertilizer is also suitable for use in tree watering bags.

Summary: The Spring is the most important time for fertilizing trees.

• With the start of the growing season, the need for nutrients increases significantly as the trees develop new leaves, shoots, and roots. Targeted and balanced fertilization can support growth during this phase and prepare the tree for further growth throughout the summer. 
• Organic fertilizers are particularly suitable, as they release their nutrients gradually and simultaneously promote soil life. 
• It is important to fertilize moderately and combine it with good soil care. Living soil forms the basis for healthy trees.
