These large, high-quality cherries were grown in Yantai, Shandong, where CalMax was used to support fruit development and quality.
Skin cracking or splitting at maturity can be a significant cause of crop loss in cherries and plums. Factors such as heavy rainfall, rapid fruit growth and inadequate calcium availability can all increase the risk of cracking and reduce marketable yield.
CalMax supplies calcium to support fruit development and can help:
- Maintain calcium availability during periods of rapid fruit growth.
- Improve fruit firmness and storage life.
- Support flower retention and fruit set.
- Promote the production of high-quality, marketable fruit.
Plums & Cherries
For plums and cherries, CalMax can be applied from the early fruit stage to help maintain calcium availability during fruit development.
Rate: 4–6 litres/ha
Timing: From the early fruit stage
Application: 3–4 sprays at 10–14 day intervals

- CalMax Ultra is an inorganic suspension fertilizer containing calcium and a balanced ratio of nitrogen, magnesium and micronutrients, formulated with ebaTM additives to significantly improve calcium uptake.
The importance of calcium in fruit and vegetables
- Calcium is one of the main constitutes of cell walls in plants. When it is in short supply, the structure of the cells weaken, resulting in various disorders.
- Calcium is instrumental in protecting the plant from toxins and slows down the ageing process.
- Deficiency symptoms can occur even when there are adequate levels present in the soil.
- Calcium is not very mobile in the plant and during periods of rapid growth or stress, the supply of this element to low transpiring organs like fruit or young leaves can be impacted.
- Stress periods are often attributable to hot, dry weather, drying winds or high humidity.
- Excessive use of nitrogen or potassium fertilisers can inhibit calcium uptake from the soil.
- There is evidence to show that calcium plays a major role in protecting plants against fungal attack by helping to provide a physical barrier.
- Calcium is essential for cell division and development of the active root and shoot tips. Calcium plays a central role in plant structure both above and below ground
- Calcium acts as a binding agent that is essential to the structure of stems, roots and fruits.
- Calcium is vital for activating enzymes that promote growth and stimulate immune system responses.
- Adequate levels of calcium are essential in fruit and vegetables, which are to be transported and displayed for sale.
- The application of CalMax products ensures optimum quality and shelf life.
