Gardening Tips : How Do Crops Respond to Phosphorus Fertilizer?


Hi this is Yolanda Vanveen and in this segment
we are going to talk about how do crops respond to Phosphorus Fertilizer? Now we all know
about nitrogen because that is what most fertilizers have a large percentage of nitrogen in them.
So my theory about fertilizer is just like our diet. Fertilizer is like a vitamin so
if your plants have good compose or really good organic matter that means leaves or grass
clippings or any type of foliage that is dying back it breaks down and it gives them their
energy and gives them their vitamins that they need for the next year. So you really
don’t need to fertilize your plants if you are giving them good organic composts. That’s
number one and when you are giving them compost in the cycle of the plant, they grow, they
are beautiful, they bloom, they die back in the Fall and they mulch themselves. When they
die down all the leaves drop and they mulch themselves and then in the Spring the mulch
dies back and makes great soil. It is organic and then when the plant grows in the Spring
it needs nitrogen. Nitrogen is for the greenery so it will take all the nitrogen out of the
soil to grow the lush greenery. Well by the time Summer hits nitrogen is gone. There is
not a lot of nitrogen left in those grass clippings or in your compost or any type of
organic matter, it breaks down and that is when the Phosphorus is important because Phosphorus
is needed for the bloom so for a plant to bloom well it needs Phosphorus so it is a
wonderful mineral that is needed for your plant and then in the Fall your plant needs
Phosphorus to survive the Winter so if you give it, keep giving it nitrogen based fertilizers
through the Fall you are not really doing the plant any favors because then they are
getting rid of their Phosphorus. They are not using, they are not saving up for the
Winter. So if you let them use their own energy and use their own Phosphorus out of the ground
that’s the best way to do it but you can always add some Phosphorus fertilizer to your plants
to get more blooms and to give them a little more oomph for the Winter and a little bit
goes a long way with Phosphorus. The plants will bloom a lot better and be more colorful
if you give them a little Phosphorus but in the end you don’t want to give them too much
either because you can actually poison them because plants are just like us. They can’t
handle too many minerals at one time. So in the end if it is not broke don’t fix it. Give
your plants really good compost, let them go through that cycle of taking in the nitrogen
and then the Phosphorus in the Fall and they need that Phosphorus to survive the Winter
because they have found that plants have the most Phosphorus in their system in the Fall
so that they can survive the cold Winters. So it is a good way you can help your plant
by giving them fertilizer but in the end compost is all they really need.

  1. What is the B1 plant additive I see at Home Depot in that big 1 gallon jug? I have never bought it but see it all the time.
