A question for people in the know. What is the best time to apply P & K
during a plants growing cycle?

especially in relation to seeding plants like cucumbers & tomatos or root
vegetables like potatos etc.

Many thanks.

Phosphorus does not dissolve and leach through the soil. Instead, it
needs to be dug into the soil to where plant roots will find it. Thus,
phosphorus should be applied before planting.
