Definitely not tomato plant food. If they are in the ground they don't need 'feeding' as such just mulch with composted bark or the like if you want to. If in containers feed with a slow release fertiliser in spring and early summer.

Tomato feed is what you use to encourage flowers and fruit.

I give my Japanese maples Sequestrine because they're said to colour better in acid soil (which I don't have).

They'll do fine in neutral soil but if yours is alkaline then, yes, sequestrine will help Sheila.

Thank you for all your comments
