Hi Everybody,

Springtime here, and my tomatoes are in.

What is the most appropriate stuff for giving them
calcium (to prevent blossum-end-rot), while respecting
their PH acidity needs?

I am guessing blood-n-bone-meal? Sprinkled liberally?

They are in 20-litre (5-gal) buckets, with generic
potting mix plus household compost.

I did same here (our spring) and just mixed in a couple of handfuls of
calcium carbonate specified for lawns. pH remained on acid side.
Best done before planting.
