I have bought Yates Leaf Greener Iron Chelate for root or foliar application for my roses, but the back of the bottle says "DO NOT apply during flowering". Why is this?

You should not apply this product to the foliage while the plant is flowering as it will burn the delicate petals. This is also why you should not apply the product if your plant is suffering from water stress. Foliar application is a good way to deliver iron to a plant quickly.
