Geraniumsare quite easy to deal for , but this does n’t stop many from panicking when they find out their prized geranium might not be geranium at all .
This is because the most democratic geraniums are in reality from the genus Pelargonium ( pe - lar - GO - nee - um ) , which was separated from the main Geranium ( jer - AY - nee - um ) genus in 1789 but never lost the common name .
However , while there are some pernicious difference between the two general , care necessity are almost identical except for temperature indigence .
One of the biggest headache is fertilizer , which one would await geraniums to need in abundance .
Yet these plant life are not heavy feeders , especially the hardy geraniums ( Geranium spp . ) , cold - tolerant perennial accommodate for life in the deal .
Too much fertilizer can in reality lead to chemical substance burn and health issues , so relief is key .
Here ’s what you need to know to ensure your geraniums get the right amount of intellectual nourishment to give spectacular blooms every class .
Best Plant Fertilizer for Geraniums
As name , geraniums do n’t want heavy fecundation , and fluent fertilizers tend to make best , as they ’re less likely to be bleed from the filth .
However , Geraniums necessitate fertilizer for level-headed bloom , especially when grown in containers .
It ’s also possible to use homemade compost - based commixture if you wish to go altogether constitutional .
The Numbers Game: Different NPKs for Different Jobs
While you’re able to give your geraniums a balanced swimming fertiliser bi - weekly or monthly , it ’s a proficient mind to switch thing up depending on the time of class .
When it descend to the NPK ratio , these three essential food play different roles , think of you ’ll need more or less at certain times of the year .
unexampled , specially neutral pH sleep with plants will do best if you give them a 5 - 10 - 5 for their first alimentation since they need to develop strong root structure .
A balanced fertilizer ( 10 - 10 - 10 as a slow - release fertilizer or 20 - 20 - 20 as a liquid water - soluble plant food ) is perfect for both grounded and potted geranium .
Many growers opt for never-ending fertilization with a water - soluble fertilizer .
You ’ll recognize if you ’re myopic on nitrogen content if your geranium plants get yellow leaves . Phosphorus may result in icteric or red leaves and a failure to bloom .
Potassium want will do the lower leaves to break down , and the stems will become more thin .
you could also use Patio Plants Liquid Fertilizer 4 - 6 - 8 NPK , which is specially word for growing yearly geraniums .
In summation , geraniums demand several macro instruction and micronutrients to thrive , which are present in most good works food .
Of these , the ones to pay attention to most for these plants are :
Moreover , Phosphate is authoritative for succulent and long efflorescence .
food insufficiency in any of these can lead to problems quicker than other micro and macronutrients .
The good tidings is these want can often be fixed with very dim-witted remedies .
you may also augment the dirt with a medium like coffee grounds ( and the coffee filters or crushed leave of absence ) to help boost beneficial microorganisms and further boost plant health .
But there ’s one other significant thing you should bang about fecundate your plants : how much your grunge already has useable .
A soil test is important for outside plants because it can discourage you of likely problem before they happen .
For example , a soil mental test that shows a high amount of phosphorus think it ’s best to cut back a footling on the phosphorus cognitive content in your fertilizer , as too much will make potassium deficiencies .
Moreover , ensure you ’re following the dose instructions when using your fertilizer . If your fertiliser is extremely concentrated , take 1 - 2 tablespoons per gallon of piss when feeding your plant .
This is n’t as crucial for indoor plants , as commercial-grade potting mix are broadly pre - balanced and will be modify every three years to replenish the soil .
When Or How To Fertilize Geraniums?
Fertilizing geranium is n’t hard , but you should always pay care to the product recording label , as different brands may need different immersion .

more often than not address , your geranium will command a dose of fertilizer every 4 week .
However , there are a few specimens that are heavier feeders and some that command even less .
If you are n’t sure how much your particular geranium plant pauperism , start with a monthly feeding and adjust if you see signs of food issue , such as foliage color , legginess , or blush color , and aline the feeding by plus or minus one week ( count on your industrial plant , feedings may end up being as often as every 2 weeks or as infrequent as every 6 weeks ) .
Note also that hardy geranium are mostly perennials and will go through a hibernating phase , so you must cut back on feeding in the fall and resume in natural spring .
