5 Signs Your Tomatoes Need Calcium

"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."
