White chalks used for writing on black board are calcium sulfate. It can be used for tomatoes plants in the form of powder Or mixing in water.

I find that laying on the ground and baby talk each individual plant is very productive. They also love their little blossoms massaged.

Calcium carbonate for human consumption is a large molecule which is not absorbable by plants. Also if you have a good PH in your soil it will raise that value - you don’t want that. Calcium for plants is readily available as calcium sulfate. You’ll have negative effects on plants using human vitamin D and calcium and zero affect from using it as a foliar spray. If you want your plants to get calcium use, Gypsum (calcium sulfate). If you want to raise PH, add calcium carbonate to your soil by using garden lime; garden lime is for raising the PH of the soil and is not an effective way of making calcium available to your plants. The proper way to supplement calcium is by adding gypsum (calcium sulfate) or using a liquid supplement such as, Cal-Mag, or similar brand. When using liquid supplements one must adjust the PH of the liquid in order to get optimal availability of the nutrients. Do not do what this person is suggesting.

I react wood ashes with vinegar to neutralize the pH. The process also yields acetate minerals, arguably among the best forms of mineral supplementation for foliar feeding. Calcium is about 50% of wood ashes, so you can get lots of calcium in the foliar feed. This kind of feeding is also pretty much germ-free; you can get it on you or even eat it on your food without worrying about an e-coli infection.

Use lime, just a bit around the plant once a week, raises Ph, amazing results....got this tip from a jersey Farmer back in 1980....he grew tomatoes from 1946-1986. Also add sand to your soil, look up Freehold loam, that is the perfect soil for tomatoes. good luck !

Calcium is calcium no matter how you look at it but the calcium compound found in human supplements is different than what your plants need and is really unusable as for as plant absorption goes. You should also be adding any type of calcium amendments to your soil and not the leaves as plants don’t absorb calcium through their leaves. Forget any ideas you may have of using human calcium supplements and forget about making any kind of foliar spray. Stick to all natural sources of calcium such as bone meal (which is also good source of phosphorus), eggshells, seaweed or garden lime to name a few and be sure to either add it directly to the soil the year BEFORE you plant or by making a liquid solution and using it to water your soil once per month before fruit set and no more than once per week after fruit sets. Use the soil amendment method if you want to “set it and forget it” or the liquid method if you like to frequently mix up a solution to water your soil with. I prefer to set it and forget it.

Thank you! I only have a few tomato plants in 5 gallon buckets and they all have blossom end rot, next year I will be better prepared.

Eggshells dissolved in vinegar = calcium for plants

About a table spoon of mortar cement mixed in the soil when you transplant your tomato plants will work great for getting the alkaline content down, saw an old guy do this years ago, and it works.

Its for preventing blossom end rot. Calcium carbonate is not immediately bioavailable to plants and has to be broken down before being taken up by plants, accordingly not the best choice for foliar spray. Try using calcium nitrate as a foliar spray For potted plants, try using expired Tums as Calcium Cabonate instead that you have crushed which will break down and help the plant. Cheaper than gel caps!

Not only is calcium carbonate useless to plants as it is not water soluble, calcium is a non-mobile micronutrient. That means if you spray it on the leaves it's going to stay in the leaves. If you need to add calcium, dissolve some eggshells in vinegar for 48hrs, ensure the vinegar has dissolved all the shells it can, then add this at a ratio of 1/2tsp per gallon of water. Water the mixture in normally. You've created calcium acetate by reacting acetic acid with calcium carbonate.

A half cup of garden Lyme, 1 TBS white vinegar, mix into I gallon water. Water your Tom plants for a quick fix.

God bless you my tomatoes were rotting on the trees that is why I went to look up the cause of that and I saw your video

Calcium from crushed eggshells is not immediately available to the plant. It takes like 3-6 months.

this was exactly my question.

Egg shells are a great way to add calcium, but you got to ground to a powder.

Answered a question. Have calcium tablets that have expired. They still have some potency. Now I know, where to use them.

I am trying "Hi Yield" calcium nitrate ( i panicked! ) which my 'trusted' garden center carries for less than Walmart, etc. I guess I did something right, because 72 hrs. later...no blossom end rot at this point. This my 2nd amateur year of container gardening. Years ago (approx. 10) I gardened, scratch that 'farmed' a 1/2 block 'garden for my great-aunt(RIP) and she had me eventually tending 30 tomatoes, 5 X 10 okra, white asparagus, blackberries, 3 apple trees, greens (various), potatoes (various), onions(various), horseradish, radishes, peppers, beans ( pole, bush, crowder peas, purple hull peas-which we traveled 80 miles into Oklahoma to get "...the ones she had to have..." and I'm getting tired just trying to remember all including flowers. This was "in-town" of 10,000 population and my 'pay' was locals stopping by to take pictures and trying to buy our producst at 'harvest', but we just shared and I learned from my 80+ years from auntie, 'how-to-garden'. All that said, container gardening is truly a 'learning experience'. Thank you for sharing your knowledge!

Thank you so much,I think I'm starving my plant, I'm new at this but loving it.

i use a cup of old milk per gallon water in sprayer every few weeks for end rot. old milk because i just dont use it up before expires, skim milk to keep it from smelling if it has soured.

Thank you

THANKYOU. THIS WAS VERY INFROMITIVE...I WILL FOLLOW YOUR EXAMPLE....DONT MIND THESE NEGITIVE POST ...THEY JUST SHOW THERE LACK ....

Hi ! can we also use Magnesium capsules in the same way? Thanks in advance

Gerber baby food is best when young, when plants are mature , oatmeal in the soil!

thank you! I want to get them sprayed, but am unable to run to the garden center today!

Thank you for the video! I wanted to try the same thing with the same brand of calcium you're using. I can only find calcium coupled with vitamin D. Do you think that'll hurt the plant?

How to use 500mg calcium tablets for this purpose? What proportion with water? Tomatoes, fine. But will calcium help in producing good gardenia, jasmine and rose flowers?

Thank lots ma'am ..

I have been told by experts in horiculture that calcium can not be absorbed by plants through their foliage but only through their root system.

THANKS... But I use the water from boiled eggs... IT WORKS & IT'S FREE 😉

Why buy expensive human grade supplements when the garden centers have magnesium and calcium in bulk for a tenth of the price . Dont spray in the morning unless its very very early , its better to do it at night /evening so the nutrients get the time to get absorbed before the water evaporates in the morning sun, misting plants with sun out can/will burn them.

Has anyone tried the calcium supplement that's fed to chickens to make their shells stronger? It is ground oyster shell, but a very coarse grind, since chickens can process it in their crops.

The calcium tablets cost more than the tomatoes. ILL TRY THE EGGSHELLS.

You actually should do this in late evening , right before sunset.

I use crushed up time . works good

It’s 2000mg (500x4) per 2 cups water?

I use tums, cheaper and after I crush them, and mix with water it's readily available calcium, no oils like in the softgels

Just buy the proper fertiliser. Calmag, Peter's Excel Calmag balanced fertiliser, Tomato Focus Soft Water, YaraTera Calcinit (Calcium Nitrate), Calcium Oxide. One can try adding lime to the barrel of made up feed but you'll soon notice it isn't soluble

This is my first year planting any tomato's. I too have this end rot I just noticed, and plan to go get some calcium spay. I'm just now starting to get some color on the tomato's. I hope it's not to late to start spaying them. I have about 13 plants, all harvested from my compost pile. It looks like I have at least 3 varieties growing. Does anyone know if growing tomato's from a compost is a good or bad thing? These all could be green house tomato's. Next year, I plan to do some research, and not be caught off guard with the rot and the caterpillars.

I tried this last year with that the soft gel pills and when the water cooled it was basically clogged the sprayer. Used only 3. End up going back to line and composted the rest of the pills.

Thanks

I put milk powder into the soil.

calcium nitrate ?

How much calcium per gallon ?

Ver Nic infomntion thank u. Can v use calcium nitrate for flowering plants.

Looks interesting ... but I'm wondering if it really works? I don't mean anecdotally, I mean have you done any comparative tests? And thanks for posting.

My calcium tablets have talc in them. Is this a problem? Doesn't seem healthy.

Foliar spraying calcium is pointless as the leaves and fruit take up very little if any. Calcium is best added to the watering can to allow the roots to transport it to the leaves and fruit.

How often? Do you apply

Can i use potassium tablet?

the liquid gels didn't work at all, i opened them, squeezed them into the hot water and they didn't dissolve at all

Peppers need it too, along with sulfur.

fast acting or slow release? any suggestions for larger scale spraying?

Save

Can this also be used on pepper plants?

Can we add calcium and vitamin D

Gosh, we had a huge row garden when we were growing up 57'x150". We plowed, tilled, rowed, planted, side dressed with chicken shit, and miraculously plants produced bumber crops. Now day, people look at plants like little individual creatures who must be tended to as if they were people.

How does this compare to TUMS? I have been using 2 TUMS antacids in 1 gallon of water.

Well, for me, that was a waste of money. I tried cutting the gel-caps open and squirting the inside into warm (almost boiling) water and it never dissolved or broke down. It became an almost clay like blob. I also tried just dropping a couple in a cup of cold water to sit for 24 hours and, again, the casing broke apart but the inside turned into a clay like substance. I verified that my calcium capsules are "gelcaps", but this was a fail. I have now ordered something that is a ready-to-use spray that says it will help blossom rot. As a footnote - this video is a few years old, so I will assume the manufacturer has changed the formula for the inside gel.

Calcium is used by every plant not just Tomatoes its the major building block of all plants lol ALL PLANTS NEED CALCIUM if you're reading this and you're growing cannabis you better get some DAMN calcium

I apply snake oil to my veggies and they end up super-sized. Cheers.

would this be good for pepper plants?

Why not use lime?

I use tums, yep it's all calcium...crush , rub into soil add water. Dissolves right away

The calcium in the gel caps does not disolve.

Well, personally i simply apply rabbit urine. It's rich in nitrogen and calcium. So powerful is rabbit urine that you need to dilute with water using a ratio of 1:5, otherwise you will scotch the plants. Rabbit urine is also good because its a natural way of fertilizing your plants, an excellent option for organic farming enthusiasts. As it is 100% natural, there is no waiting people from day of application to first harvest date - you can even harvest soon after applying it. Another advantage of rabbit urine is that it also works as an insecticide. The strong smell that it produces while applying it and its sour and burning sensation kills garden pests such as aphids.

Feed the roots.

Could I just use chalk?

If you’re by a beach Crush up cuttlefish bones So cheap it’s free

What calcium tablet did you use madam

How often do you use this?

Oh deary me. Calcium... through the leaves. Smh

you say to let the water mix to cool down and then -for the sake of showing how to spray- you use the hot water on a poor real plant!!! OMG! so sad.... :(

Wasn't this lady an actress on that older sitcom called TAXI?

What type of calcium?

Nice hammers!

Lol I have no questions

Looks like way more than a cup of hot water!

Dollar store calcium pill is not expensive !!

Tomatoes cannot absorb calcium through their leaves. This video is totally misleading. Do your research.

stupid hacks. cant find any good video on calcium nitrate, which is what farmers use..instead of useless calcium alone as a spray, of unknown concentration.

What an absolute silly waste of time and money.

Do not do this

What a waste... Save your money a use crushed egg shells.

You literally said nothing about how many milligrams of calcium nitrate per milliliter of water or anything. Lol. Next time, provide better information.

Wow that tomato plant looks like crap!

Some bad advice right here.!

Plants don’t like gel they like dirt. Horrible video
