Should You Fertilize Your Bonsai?
Trees in nature have all-encompassing root systems to maximize water and nutrient accomplishment , but this is not the case with Bonsai , which are confined to shallow skunk and have compromise ascendant systems .
The Bonsai artist ’s essential part is to meet the plant ’s nutritionary need .
Too much fertilizer can cause more harm than good , and a goodly approach is to focus on cultivating soil health rather than rivet on outgrowth . The former precedes the latter .
Soil Testing
There ’s an adage , “ Measure what weigh . ” Healthy dirt is the fundament for all your gardening dream , so knowing its condition is critical . grime testsinform you of your soil ’s nutrient level , pH , and ability to manage those nutrients – the Cation Exchange Capacity ( CEC ) .
Soil pH
The test will assure you if your soil is sour ( acidic ) or sweet ( alkaline ) – it even tells you if lime is need and how much . An iron deficiency is often triggered by too alkaline soil – a high pH.
The test results will indicate the actual pH compared to the target range of a function – base on soil character and what you intend to grow .
Generally , lime is tot up to increase the pH , and S lessen the pH ( increase the acidity ) . LimeLifts , and SulfurSuppressesit .
Understanding Soiltest Recommendations
The trial ’s passport will specify the quantity per thousand square foot and the NKP proportion . get ’s go over the turn :
The test measures the phosphorus and K mental object – nitrogen is too volatile to assess accurately and is often the most constrictive nutrient .
Nitrogen
Phosphorus
Note : Phosphorus is not taken up well in moth-eaten or wet dirt . lack symptom in wintertime are usually due to cold weather rather than a want of nutrient in the soil

The Essential Nutrient Element – Organic Matter (Compost)
Compost has several benefitsonly it can provide – improved soil health , germ support , ploughland advance , pH buffering , and aggregate establishment . It adds some nutrient , but its primary benefit is the soil ’s improved water and nutrient - holding capacity – it enhances the efficacy of fertilizers .
Organic Fertilizer Alternatives
Cation Exchange Capacity (CEC)
Your reputation will allow for you with a CEC measurement , the ability of your ground to check and release urine and nutrient to your plants – think of it as your soil ’s nourishing magnetism .
There ’s a whole science to CEC , but the reply is always organic matter – compost . Compost can boost your CEC beyond what any other substance can .
Fertilizer Timing for Bonsai Development Phases
Phase I: Growing Material
Our goal in the former stage of bonsai development should be to ensure that it grow as healthily as possible . At this point , the aim of growth is to take form a thick-skulled tree trunk .
The fertilizer required at this percentage point should be balanced , although it may favor nitrogen because it is the key component part for vegetative development .
It is important to ensure the works receives a consistent supplying ; thus , slow - liberation fertilizer is thoroughgoing .
Phase II: Bonsai Branch Structure Development
Since the first stage of development is reasonably frantic , there is a hazard that common branch will germinate that are out of proportion to the trunk .
control limb development is the goal , and allow offset ontogenesis on trees with unusually robust trunks while still in the field will hurry the cognitive process .
Phase III: Ramification
After develop a basic branch social system , you should develop secondary outgrowth to create bulk in the foliage canopy or pads . Feeding ascendance is essential in the fork phase angle .
Excessive feeding will result in very long internodes , which is unsuitable as it will specify the bit of all right twigs you’re able to grow or substantiate in the neighborhood or zone of the outline or silhouette of the canopy .
Too little fertilizer , however , will weaken the tree ’s ability to support defoliation , a key proficiency needed when developing ramifications .
Final Phase: Refinement and Maintenance
It would facilitate if you aimed for limited growth and maximal health in this final and extended phase , control your tree is live against diseases and dirt ball attacks .
Incorrect fertilizing can lead to branch die - back – where small twigs block off growing , peculiarly in fountain . While fertilizer may be the effort , inadequate maturate medium could also be the culprit .
A Season Bonsai Feeding Guide
Spring
Because everything grows in the outflow , any nutrient in the originate culture medium need replenishment . All young , developing trees , especially true pine , should be fed from the start of the season to help the decandling process . ( which demand the unadulterated removal of leave spring shoot )
However , it is dear to wait a few week until the spring leaves harden off before fertilizing more developed or elegant trees .
Summer
The heat in the summertime might cause your tree ’ increase to either slow down importantly or terminate altogether , depending on where you are locate and if your climate is tropic or not .
you could resume when the temperature falls once more . Your trees typically respond with another growth spurt , though it wo n’t be as potent as in the spring .
Autumn
It ’s crucial to run your Bonsai now , pre - dormancy since it guarantees your trees will accumulate a provision of nutrients to advance development the following bound .
If you have a Nipponese white true pine , you probably already know that , with a few exception , fecundation is only done in the nightfall as this is the way to manipulate needle distance ( as these trees are not subjected to the same decandling technique which twofold flush , two - needle pines are ) .
Some incorrect advice , to the effect that you should not stimulate development in your trees when they should be shutting down , is being marketed as common soundness .
This advice fail to acknowledge that all plants ask all three substantive building pulley ( NKP ) for veritable cell mathematical function .
Thus , utilize plant food that eliminates or provides N , atomic number 15 , or potassium at nearly minute stage will confine the plant ’s ability to function decently .
This does not refer to foliage growth only but all works functions . or else , whenever fertilizing , use a pocket-size , balanced fertiliser .
Winter
Tree get in a dormant state during the winter , with minimal or no maturation . Again , this will bet on your local clime , but if your tree go through a sleeping time of year , plant food will not be necessary and will just be squandered if you do .
Another rationality to avoid fertilizing during these times is minimum absorption via the fine root hairs in frigid climates .
Bonsai Fertilizing by Tree Species
The alimentation quota varies according to plant mintage ; just as a 7 - ft grid - iron player require more food than I do , some Sir Herbert Beerbohm Tree specie need more nutrients than others .
Generally , this is the shell with anything which thrives . Species like the Australian Brush Cherry or Syzygium and the Wisteria vine come to mind , but many others exist .
These plant have exceptionally speedy growth , so they can quickly exhaust the nutrients in their prompt surroundings , and this depletion will occur more speedily in a belittled area .
Some plant charge instructions remark that a particular species is a gross feeder or comparable ; however , this is not always true .
So , in general , if a tree is frequently utilized as a hedge , like the previously cite Brush Cherry , privet , kei apple , firethorn , and others , it is probable a mintage that requires a lot of food .
What Can Go Wrong When You Feed Your Bonsai Too Close to Winter?
flora need resiliency to abide the winter freezing . Part of that resilience come from having a healthy , established plant at the end of the develop time of year .
reinvigorated growth taxes the plant life ’s energy , even if supported by fertilizer . The stress of the grow phase angle makes the plant more susceptible to disease and attractive to pestilence . Maturity has advantage , and boosting growth too close-fitting to the winter months could do terms from which the plant can not recover .
To avoid this , do n’t bring food to your bonsai from 21 - days before the first Robert Frost .
Annual Fertilizer Schedule For Bonsai
Your bonsai industrial plant do n’t need a lot of food . fertilize every 2d class is enough , especially if the bonsai plant are well establish .
The in force fertilizer is organic , and the food in compost are enough for an annual feed .
If you wish to boost your Bonsai leaves for a brighter show , do this about 42 day after the last frost when the plants have had an opportunity to acclimatize to the warm weather and the 2nd set of leaves has emerge .
If you ’re repotting your Bonsai , do it at least a month before the first rime engagement . Consider aiding the reheating of your stain for an extended produce time of year with a seedling growth mat .
