Bacterial heart rot is mainly caused by calcium and boron deficiency combined with bacterial infection in the plant’s core. This condition typically affects tender inner tissues, leading to blackening, soft rot, and eventual plant decline if not treated early.
It is commonly seen in crops where nutrient imbalance and environmental stress weaken plant structure, making them more vulnerable to infection.
How to prevent and control bacterial heart rot
To effectively manage this condition, both nutrient supplementation and bacterial control are required.
Start by strengthening plant tissues using Mr Ganick Organic CalMagBo+, mixed at 40 ml per 20 L of water. Spray weekly for three consecutive weeks to improve nutrient absorption and reduce rot symptoms.
At the same time, control bacterial infection by alternating:
- Mr Ganick Bact-X Concentrate (60 ml/20 L water)
- Mr Ganick BST (30 g/20 L water)
Apply weekly for three consecutive weeks. This helps suppress bacteria, repair damaged tissues, and protect new growth.
The above agents can also be mixed for a synergistic effect:
- Mr Ganick Organic CalMagBo+: 30ml/20L water
- Mr Ganick Bact-X Concentrate: 30ml/20L water
- Mr Ganick BST: 20g/20L water (approximately 2 tablespoons)
Combined treatment for better results
For a more efficient approach, these products can be combined:
- Mr Ganick Organic CalMagBo+: 30 ml / 20 L water
- Mr Ganick Bact-X Concentrate: 30 ml / 20 L water
- Mr Ganick BST: 20 g / 20 L water
This combination provides both nutrient support and disease control simultaneously, improving recovery speed.
What are the main causes of bacterial heart rot?
1. Calcium and boron deficiency
Calcium and boron are essential for maintaining strong plant cell walls and healthy tissue development. When these nutrients are lacking:
- New shoots become weak and soft
- Inner tissues are prone to blackening
- Rot develops more easily in the plant’s core
This issue is often worsened by uneven nutrient distribution in the soil or poor nutrient absorption due to root stress.
2. Bacterial infection in the core
Bacterial pathogens can enter and infect the plant’s inner tissues, causing decay from the inside out. This is especially common under:
- High humidity
- Poor ventilation
- Excessively wet soil conditions
Once infected, the plant’s core begins to rot, leading to visible symptoms such as blackened centers and stunted growth.
How to know if the problem is under control
You should observe:
- Healthier new shoots without blackening
- Reduced spread of rot in the center
- Stronger plant growth
Damaged tissues may not recover, but new growth will indicate success.
Bacterial heart rot is caused by nutrient deficiency and bacterial infection working together. By correcting nutrient imbalance and controlling bacteria early, you can prevent severe damage and restore plant health
Protect your crops before rot spreads further
Bacterial heart rot can spread quickly once the plant core is affected, so early care is important. Strengthening the plant with Mr Ganick Organic CalMagBo+ while managing bacterial infection with Mr Ganick Bact-X Concentrate and Mr Ganick BST helps support healthier new growth and reduce future damage.
