In fact plants acidic fertilizer is also important as that of organic fertilizers for plants (azaleas,roses,rhododendrons, blueberry, hibiscus and other acid-loving plants) needs acidic fertilizers.For instance,eggshells are almost 100% calcium carbonate, one of the main ingredients in agricultural lime; vinegar has acetic acid; & coffee not only lowers your soil pH ,it also enriches it with nitrogen,magnesium and potassium.
too much use of fertilizer can make soil too acidic so thee fertilizers should be used in a limit.


are some of the accidic fertilizers wich can be made in home with less cost for plants.

Step 1: Epsom Salt Fertilizer

 Epsom salt fertilizer:use in place vegetable plants,rose plant, peppers,houseplants

1 table spoon Epsom salt
1 gallon of water

combine the Epsom salt and water and use this solution to water your plants.repeat once a month. Epsom salt is made up of magnesium and sulphate-both vital plant nutrients.
<p>Please don't use marine fish tank water, it's basically sea water.</p>
It could do with your own pictures of things you made.<br /> Egg shells are not acidic, you might want to mention that.<br /> <br /> L<br />
&nbsp;though egg shells are nt acidic they contain calcium carbonate n essential element for plants&nbsp;growth...
Yes, but under the title &quot;Acidic Fertiliser&quot; you might want to point out that carbonate is a bit basic / alkaline.<br /> <br /> L<br />
The title to this instructable is accidentally misleading. It would be a nice gesture if the author would rename it more accurately. Thank you!<br><br>Perhaps &quot;Household acid and base fertilizers&quot; would work for you?
Well it's been ~18 months and it hasn't happened. I'm not too concerned.<br> <br> L
<strong>Lemonie:</strong> I've taken eggshells and dissolved them in vinegar, got some fine powder and sometimes some crystals precipitated out.<br> <br> After thinking about it as a way to give calcium to plants I decided that just crushing eggshells into my compost mix would work as well. Time, bacteria, rain, and regular watering should get the calcium into the root systems. I figure this to be true because oyster shell calcium is sold for gardening and that is not precipitated out in fine powder. It seems to dissolve naturally in the environment of the soil.<br> <br> On another note: If coffee grounds are going to be spread upon the soil, why bother drying them? It seems to work fine dumped onto the base of the rose plants. (Grandma taught me that one years ago.)
I had the same question about the coffee grounds. Thank you!
This isn't my instructable, but I think you could put an interesting/useful one together. Do you think so?<br> <br> L
I appreciate the encouragement. I've been only partially engaged with the whole Instructables process for some time now. Looking forward to doing a well documented Instructable after I put all the photos and facts together.
Can you add egg shells, coffee and epson salt together? Why do you need to dry out coffee grinds?
