5 Signs Your Tomatoes Need Calcium.
And How Restore Calcium Can Save Your Harvest
“Mama Joyce from Kiirua, Meru sadly stared at her tomatoes. Half of them had dark, sunken spots at the bottom – blossom end rot. The buyer rejected them. She lost KES 20,000 from that single harvest. She didn’t know her tomatoes were starving for calcium.”
“The next season, she used Restore Calcium. Not a single rotten fruit. She earned KES 50,000. The difference? Calcium.”
Calcium is immobile in plants. Unlike nitrogen or potassium, once calcium is deposited in leaves, it cannot move to fruits. That is why deficiency shows up first in developing fruits – they cannot “borrow” calcium from older leaves.
Did you know? : Calcium strengthens cell walls. Without it, cells collapse, creating the classic sunken, leathery spot at the blossom end (the bottom of the fruit).
What to check for
Sign | What It Looks Like | Why It Happens |
1. Blossom end rot | Dark, sunken spot at the bottom of the fruit | Cells collapse due to weak walls |
2. Cracked fruits | Circular cracks around the fruit shoulder | Uneven growth from weak cell structure |
3. Stunted new growth | Young leaves are small, distorted, or die back | Calcium is needed for cell division at growing tips |
4. Blossom drop | Flowers turn brown and fall off without setting fruit | Calcium is essential for pollen tube growth |
5. Soft, mushy fruits | Fruits feel soft and rot quickly after harvest | Calcium preserves firmness and shelf life |
There’s a remedy
Restore Calcium delivers 40% calcium plus magnesium (for photosynthesis) and plant stimulants (for faster uptake).Prevention is better than cure: Start applying Restore Calcium when fruits are marble-sized – before symptoms appear.
“Calcium deficiency in tomatoes (Solanum lycopersicum) leads to blossom end rot due to impaired cell wall formation. Foliar calcium application at fruit set significantly reduces incidence and improves fruit firmness and shelf life.”
