Calcium Products – What is calcium and how to use calcium in gardening


what is calcium and why is it important
for plants how do you apply calcium products in your home garden answers to
all these questions and more and today’s episode of California gardening so what
is calcium along with magnesium and sulfur calcium is one of the three
secondary nutrients that are needed by plants for optimum growth other than
primary nutrients like nitrogen phosphorus and potassium calcium is one
of the secondary nutrients that a plant needs for healthy growth and although
calcium is needed by plants they are needed in lesser amounts compared to the
primary nutrients that the plants need and now let’s look at some sources for
calcium that you can use in your home garden the first option is an organic
fertilizer like the one you see here this is a tomato vegetable and herb
fertilizer if you look at what’s contained in this fertilizer you can
clearly see that it contains calcium and this type of calcium is a slow-release
calcium so it will be absorbed by your plants as and when it needs it the next
source for calcium is garden lime now garden lime should be used carefully
because it’s an excellent source of calcium but it alters the pH of the soil
so if you look at the ingredients or what the garden lime contains you can
see a lot of types of calcium that are there in garden lime and it can be
readily used by plants it’s quick release as well as slow release another
source for calcium is seaweed or kelp as you can see here the calcium in
seaweed or kelp is listed differently than the solid products because this is
mostly used as a liquid product and this is an excellent source of calcium
because it’s available to the plants immediately and you can even use a
foliar spray to apply this and seaweed or kelp meal is one of the better
sources of calcium because it’s readily available for the plants now you also
can use calcium nitrate which is a salt and this is the most readily available
source of calcium and I will shortly show you how to use
these products in your home garden now gypsum is another source of calcium and
you can buy gypsum as garden gypsum or large bags of gypsum and gypsum is
generally more expensive because it not only contains calcium it also breaks
down hard clay soil and is very effective if you’re gardening in the
ground it’s not so effective in containers for breaking down compacted
soil because for containers you mostly use container mixes now let’s look at
what happens if your plants have a calcium deficiency plants need calcium
for developing healthy leaves stems and cell walls and a lack of calcium in your
plants will show up like these leaves which look quite disfigured almost like
bubbling leaves and a very common calcium deficiency can be seen in
vegetables like tomatoes and bell peppers and this is called blossom and
rot and as you can see here the bottom part of the fruit actually is deformed
it’s almost like it is rotting and this one of the most common reasons why
gardeners use calcium in your home garden now let’s look at how you can
apply these calcium products in your garden beginning with calcium nitrate
which is a salt all you do is dissolve the salt in water I use one tablespoon
in two gallons of water and this is a very readily available source of calcium
you just have to be careful that calcium nitrate also contains nitrogen and you
do not want to apply excess nitrogen to a lot of your vegetables as you can see
here we are doing a foliar application where we are drenching the plant with
this solution and as the solution goes down and into the roots it will be
absorbed by the plant as well so I generally do both I do a foliar
application where I am drenching the plant the leaves and the stem so that
the calcium can be absorbed and I’m also watering
the base of the plant now it’s important to remember that calcium is an immobile
nutrient which means that you need to keep reapplying calcium as and when the
plant needs it now let’s look at how to apply calcium using organic fertilizers
as you can see here we are spreading the fertilizer on the base of the plant and
this will provide enough calcium as the plant grows let’s now look at how to use
gypsum now gypsum is available as pellets and the best time to apply
gypsum is to apply it when you are preparing your raised beds that way it
gets into your soil very well and then you just mix it in or water once you are
done and for established plants you can just sprinkle some gypsum I just eyeball
it and put it around the plant and it’s a great calcium supplement for your
plants now when you’re buying gypsum you need to make sure that you buy calcium
dihydrate which is more readily available for your plants so I hope you

  1. I have been using egg shells. We consume lot of eggs, we save the shell.. let them dry and grind them to power in a mixer and sprinkle a handful once in 2 months or so.

  2. We had our soil tested (lawn) and our calcium was off the charts high. It was listed at the high end off "Excessive" on the graph and as 4616 lbs/acre in the description. Is there anything (organic) we can do to offset the high calcium or is it even necessary? I guess I should plant some tomatoes and peppers. 🙂

  3. Why not use your egg shels for Calcium? I grind them and mix it with my soil far before I plant my plant so it can be assorbed by the soil before I plant my plant. This way I reduce my garbadge and give back to my soil…

  4. But does calcium salts end up with a non reactive bi product into soil? Which can not be reversed and hence damage ths soil permanently? Please explain.

  5. Do plants need fertilizer in cold winter months ? What,are do s and don't s as far as fertilizers in cold winter months ?

  6. The chilly plants are flowering but no chillies have appeared as yet. There are many flowers that have come but till date not a single chilly in sight. Could you please let me know what to do.

  7. I know you do a lot of container gardening but you should look into square foot gardening. It's really cool for someone like me who can only do containers and small beds. Just s recommendation. Would love to see that.

  12. I watered my tomatoes with calcium nitrate per your instructions, appears to have burned a few blossoms. Can I add it directly to the buckets instead of spraying the foliage?

  13. It was quite informative. Thanks a lot. Yet I would like to know how often it needs to be applied in a potted plant.

  14. I'm using now for the first time Calcium Carbonate (CaCO3) on pepper plant because the leaves are small and crickled. 1/2 tease spoon for every 2000 mL ,I'm doing it right ?
