A couple of tomatoes from a plant have not ripened properly. The same plant has produced many other tomatoes which have ripened fine. Are they safe to eat ?
Zinnia I grow Zinnias every year and they are very easy to grow. If left alone they will bear many flowers. I am in the UK and usually sow around April. I do not deadhead any of the dried flowers but leave them for the birds and insects. This way you will have seeds for future sowings, just keep them dry and you will have next years' Zinnias.
