geranium ( jer - AY - nee - um ) can get a little puzzling for first - time owners and even experienced agriculturalist sometimes have way out with these plant .
It ’s no fracture of the somebody , but rather the fact that most usual geraniums are in reality from the genus Pelargonium ( pe - lar - GO - nee - um ) , which was split from the actual Geranium genus in 1789 but still shares the common name .
What ’s even more puzzling is that true geranium ( also call hardy geraniums orcranesbills ) have 400 + mintage compared to pelargonium ’s 280 yet most guides will tell you about only pelargoniums .
Geranium plant life are more equatorial yet rise in sight , so they ’re very cold hardy , and grown as perennials .
Meanwhile , Pelargonium are mostly annuals from South Africa and actually want more tropical temperatures , making this one of the most backward and notable preeminence between the two genera .
But whether you have a genus Pelargonium or reliable geranium , one thing is sure : they both have very interchangeable water requirements .
What Are My Geranium’s Water Requirements?
Hardy geraniums can be drouth liberal once established , but still follow the same preference for about 1 ” inch of rainfall per week that pelargoniums do .
The good word is that it ’s quite easy to assure your geranium gets just the veracious amount of moisture and it will let you know when there ’s a lacrimation issue .

Growing Geraniums Starts With Good Soil Preparation
If you want to get the tearing the right way , your first stop should always be the dirt itself .
One of the adept room to help ascertain your garden does n’t flood is to supply a substratum of crushed rock underneath the planting surface area .
This creates a buffer zone that can hold water away from plant roots while work its direction down to the piddle mesa .
you may also sum a base bed of gravel or pebble in a stack to perform the same function .
Geraniums like a loamy soil with a flake of sandy grain to it , although hardy geraniums can last in almost any soil .
Whether grease one’s palms a potting mix or planting in the garden , make certain there ’s a seemly amount of organic material in the soil as well as some coarse grit or perlite .
Two parts land to one part constitutional fabric and one part aggregate is a skillful blending to drive for .
The organic material present in the stain ( especially mosses ) hold some water , which can be useful in drought conditions .
Meanwhile , the aggregate prevents the soil from pack together too much and leaves some air travel zona .
Perlite and similar aggregates may also hold onto a moment of water , but their main part is to give the rootage more outer space to drink and help in drainage .
Thus , when your works is n’t drinking properly , the soil may well be to blame .
The Soak and Dry Method
Once you ’re certain the soil is well - draining , you may focus on the watering itself . All geranium respond well to the inebriate - and - teetotal method .
The process is very uncomplicated : Since geraniums like 1 ” inch of rain per calendar week , you’re able to simply stick your digit in the soil to see if it involve a drink .
The soil should never be wet or miry , which is a bigger risk in the garden than in container if you get a lot of rain .
Never irrigate when the territory is this stiff .
However , if the dirt feel wry 1 ” inch deep , your geranium is quick for a potable .
Water by hand , deflect a garden hosiery or nebulizer , as geraniums can get fungous infections if their leaves are wet and it can be harder to pass judgment when to intercept lacrimation .
apply room temperature water supply to avoid shocking the plant life , preferably innate rainwater or distilled water .
Pour slowly and equally around the base of the plant so the grunge has time to hit it up it up .
With potted plants , you ’ll know to finish when you see seepage from the drain holes .
For garden plants , it ’s usually a just thought to stop if you see the soil begin to absorb the water slower .
Common Mistakes
Two of the most common mistake are intimately related and are sadly still being taught to children .
You should NEVER water on a set schedule and NEVER go apace .
This can easy extend to overwatering or underwatering .
Several broker affect how often a plant needs to drink , so ask yourself :
As a general convention , plants will need to be watered more often when it ’s really spicy , sunny , and/or arid out but less if it ’s cold , sunless , or humid .
A divided plant will have a small root system than one that has n’t been separate for a twelvemonth or two .
Using your finger to check how far down the grunge is dry can be one of the easiest ways to know if the plant is thirsty , and it only take a moment of your time , so drive to check off one or two time per calendar week based on the above constituent and water accordingly .
Likewise , giving a agile pour from a lacrimation can or fast spray from a hose will likely not be enough .
Remember that water and fertilizer call for to soak into the ground and will spread out as it tries to work its means down to the water table , so a tedious , long pour will ensure you do n’t give the plant too much or too little .
Excess Water The Risks of Overwatering
Overwatering geraniums can lead to radical rot , a deathly disease do by either fungal or bacterial infections that destroy etymon so the plant ca n’t get water or nutrients .
Fungal infection are also a common side core with these plants , as is a high risk of infestations .
depend on the species , the leaves may begin to turn yellow or crimson as well .
Risks of Underwatering
Hardy geraniums are more large-minded of drought than Pelargonium , but both still take sufficient water .
yellowish or crimson leaves are the primary mark of underwatering , and the plant may suffer bud bead or lead off to lose its foliage as the dehydration continues .
