The splendor of a Mexican flameleaf is obvious to all who lay their eye upon it .
Even when it ’s not in bloom with colourful bracts , its foliage is quite outstanding , and once the topmost bracts develop bright vacation hue in wintertime , the plant becomes even more of a smasher .
But such a fantastic video display would be unacceptable without proper fertilisation .

When a poinsettia is blend through all that emergence and development , lots of nutrient are used up at a rapid rate .
Without once in a while restock these minerals , Euphorbia pulcherrimawill begin to get . And a works that ’s deficient in a few primal nutrient can go from stunning to sad “ real quick , ” as we say here in the Midwest .
But a Midwesterner saying “ real quick ” is anything but , and a sorry poinsettia is not a hopeless caseful .
In this guide , we ’ll cover how and why to fertilize these plant , along with what you ’ll call for for the task . We ’ll even throw in some additional reasons why , for those in demand of extra motivation !
Here ’s all we ’ll cover up out front :
What You’ll Learn
Why Fertilize Poinsettias?
“ Why ? ” is a question deserving asking , whether you ’re fertilize poinsettias or in line of work at the Apple store , eager to get your hands on the late iPhone .
But unlike waiting for the iPhone 83 SE Pro Max Plus – or whatever manikin they ’re up to by the time you ’re understand this – fertilizingE. pulcherrimais time well spent , for a few reasons :
Aesthetics
When a Euphorbia pulcherrima ’s nutritionary requirements are meet , it has all the resources it need to produce gorgeously colorful bract for the vacation time of year , and vivacious greenery .
Conversely , a nutritional insufficiency will drain the beauty from a plant ’s foliage faster than the Sonic the Hedgehog spins after a quintuple - slam of espresso .
Vigor
Speaking of quickness , a by rights - fertilizedE. pulcherrimawill uprise at its maximum charge per unit .
Much like a Ferrari needs all of its portion in ordering to hurry around the track , a poinsettia needs all of its of the essence nutrients in rules of order to rapidly enlarge and develop new structures .
Health
All of the above does n’t weigh if the poinsettia is beset with pestilence or pathogen .
as luck would have it , fertilization is a dependable way of support yourE. pulcherrimafrom health issues , since properly - fed plant are able to withstand infestation and infection much better than when they ’re deprive of necessary nutrition .

What You’ll Need
for carry out this all - too - necessary poinsettia care procedure , you ca n’t go in empty - handed . Here ’s what ’s required :
Humus
“ Awesome , I love Hellenic intellectual nourishment ! Will we also involve Pita brea – ”
Hate to burst your bubble , but you ’re thinking ofhummus … I ’m spill abouthumus , which is the black constituent subject remaining in the dirt after flora and fauna decompose .
It ’s way less tasty to us than the chickpea - based Mediterranean dip , but flora such asE. pulcherrimaabsolutely love it , for a variety of reasons .
For one , it meliorate grunge structure . When organic issue is add together to the land , it clumps soil particles together into aggregates , which sit atop each other like marbles in a jarful , gumballs in a gumball machine , or the plastic spheres in a bug - infested McDonald ’s ball Inferno .
There ’s blank space between the aggregates just like there is between wits or gumballs , which allow plenty of room for roots , air , and water to pass through the soil .
Additionally , humus increases a land ’s ability to check water . When humus forms aggregate , it create a motion-picture show around the territory particles that absorbs moisture like a sponge . Poinsettias in fussy treasure this , since they love sitting in moist ground .
And finally , humus improves fecundity via an gain in the soil ’s cation exchange capacity ( CEC ) .
This is n’t an improver of actual nutrients , but rather , an augmentation of the soil ’s power to provide useable nutriment to plants .
Let me explain :
Nutrients such as magnesium and potassium are cations , i.e. positively charged ions , which stick to negatively charged particles such as organic issue or clay – both of which have a high CEC .
Soils high in these high CEC part are capable to hold in onto and provide more food than soils null of hommos and/or frame of a low CEC material such as sand .
But a soil ’s CEC does n’t regulate its ability to change anion such as nitrate or sulfate , which are easily swept away by rain or irrigation .
Long tale light , CEC is a quantity of nutrient mobility , rather than the total sustenance in the soil – and it ’s this nutritional mobility that makes humus quite important .
you’re able to make a potting mixture with constitutional material that provides plentiful richness and nutrient uptake for potted plant with a 2:1 admixture ofpeatand perlite .
Fertilizer
If I can compare a Christmas star to a pro athlete ’s nutritional regimen for a instant : humus represents a diet rich in whole and unrefined foods , while fertilizers are the vitamin appurtenance .
For the most part , a healthy intake of organic matter covers a plant ’s nutritional bases , but sometimes a supplement is needed to address specific deficiency .
Just like an jock probably would n’t require to eat a block of high mallow that ’s full-bodied in fatty tissue and protein exclusively for the design of hitting their calcium intake goals , you would n’t want to stack hummock upon mounds of nitrogen- , potassium- , and daystar - rich compost onto the soil to solve a plant ’s insufficiency if the problem can be narrowed down to a single micronutrient .
In poinsettias , insufficiency evidence in unlike way .
A lack of calcium shows up as bract necrosis , leaf edge burns , and weak stems .
Molybdenum deficiency exhibits symptoms of interveinal and marginal necrosis in latterly ripe and in-between - ripened leaves .
Low levels of Mg cause interveinal greensickness on lower leaves , and low potassium upshot in small bracts and stunted ontogeny overall .
Not that every fertilizer is frame of a individual nutrient , of course of instruction – there are many fertilizer that are deliberate “ everlasting , ” mean they have all three of the primary plant macronutrients : nitrogen , daystar , and atomic number 19 .
Or N , phosphorus , and K , as they ’re commonly labeled on fertilizer packaging . Some include mineral micronutrients as well , while others do not .
Fertilizers are either constitutive or synthetical .
The former is made of of course - take place materials like kelp repast , blood repast , or worm cast , while the latter is pen of mined or fabricate chemical compound such as ammonium ion sulfate and potassium nitrate .
Along with being sustainable , organic plant food run to release nutrients slowly for prolonged filth enrichment , and these also offer secondary and/or follow micronutrient , which help to keep a industrial plant ’s overall nutrition balanced .
Synthetic fertilizers , while they may be cheaper , come with some notable drawbacks over organic ones .
They tend to deliver brainsick nourishment when applied in a uncaring manner , and can harm the good microorganism that repose in dirt .
It ’s also easy to over - fertilize potted plants with synthetic fertilizer , which can lead to a buildup of salts and subsequent fertilizer burn .
Plus , synthetic plant food often release their food quicker than constitutive products , which can top to fertilizer burn : a dry out - out of the roots paired with yellowed , wilt , and pass leafage .
All that ’s to say : organics are definitely the way to go , if you ’re able-bodied to practice them .
Something as simple ashomemade compostwill get the problem done , as well as box products like this constituent and all - purpose 4 - 4 - 4 NPK fertilizer , which isavailable from Burpee .
All Purpose Granular Fertilizer
Before you feed your flora , it can be helpful to know the nutritionary makeup of your grunge . Otherwise , how will you know what it necessitate ?
But this is traditionally done for basis soil in the landscape and garden .
Potted industrial plant wo n’t usually necessitate a soil examination , and container - spring up plants can easy be repotted into novel soil if they ’ve outgrown their container and the grime or soilless mix filling the container has become compacted or depleted .
You could always test the potting soil on your own byutilizing a DIY soil test kitif you ’d like to know what you ’re act upon with . But again , for indoor horticulture , this is n’t typically necessary .
Luster Leaf Soil Test Kit
If you ’d like to test the soil ’s pH and the amount of N , phosphorus , and potassium levels out in the garden for plant life growing in the ground , check out this kit from Luster Leaf that’savailable on Amazon .
When and How to Feed Your Plants
It endure without order that fertilizer type , timing , and technique are all extremely authoritative .
The idealistic pH for anE. pulcherrimais 5.8 to 6.2 , because this is the range where substantive micronutrients such as Ca , magnesium , and molybdenum are most useable .
point these to preclude lack is a slap-up idea if you ’re growing poinsettias , and most packaged potting dirt occur within this pH range .
Unless you ’ve workedcoffee groundsinto your containers , experiment with adding leftoverwood ash , or done some other originative eating with your poinsettia ’s potting soil , extreme pH problems are improbable .
Adding Al sulfate or sulfur to the soil outdoors can make it more acidic , whileadding limewill make it more alkaline .
In - ground planting grow in garden soilcan also be remediate with constitutional thing every year in the springtime . Two to four inch of well - waste manure or compost – work into the ground above the root zone – should do the trick .
Container planting are often growing in a soilless medium , which is n’t always the best pick for amending with organic stuff .
Rather than using hommos , you could fecundate container - grown plants every three weeks in spring and summertime with a complete houseplant fertilizer diluted down to half - strength .
