What is the Best Fertilizer for Indoor Plants?
Organic vs Synthetic
When it comes to choosing a plant food , first we must look at the central difference between organic and synthetic fertilizers . constituent fertilizers are derived from mineral , plant , and animate being ware , while synthetic fertiliser are synthesized chemicals of nutrients .
man-made fertilizer molecules are made to be readily uncommitted to plants and , therefore , can be hard to regularize . It ’s well-off to over - utilise semisynthetic fertilizer and cause plant to take up too much victuals too quickly , causing fertiliser “ burn . ”
constitutional fertilizers are more forgiving because , often , they are not as pronto available for plants . Natural organic plant food are break down more slow and , therefore , regulate the speed at which the food are usable , encouraging the plant to grow unchanging roots and dilate the region in which they roll up food .
Liquid vs Granular
you’re able to receive synthetical and organic houseplant fertiliser in both liquid and granular manikin . Liquid fertilizer is the easy to utilize , as you could impart it to your lachrymation can while watering the plants . It does ask to be done more frequently than farinaceous , but you are downplay the potential for fertiliser burn .
Granular plant food comes in either spikes or shot forms . You either dust or push the fertilizer into the dirt , and the nutrients are slow released . you’re able to encounter rude and organic granular plant food by checking the component list . If there is none , it is a man-made plant food .
My houseplant fertilizer recipe is an organic liquid rule . In my vox populi , this is the skilful fertilizer for indoor plant life and the one I use most regularly . It is promiscuous to make and use and provides eco - friendly , natural ontogenesis enhancement .
When Should I Fertilize My Indoor Plants?
Plants are in force at letting you make love when they necessitate water or more sunshine but not so practiced at letting you acknowledge when they need plant food . Stagnant development is often the biggest index number and is not as glaringly obvious as awilted or yellow leafage .
I primarily use my houseplant fertilizer during the summertime . While works have different needs , these feed guidelines will apply to most houseplants . The plants may experience inside , but they grow most in the summer . Since we need to encourage maturation , this is the best clock time to give fertiliser .
commence fertilizing in recent spring or or so 8 weeks before the time of year ’s last Robert Lee Frost . Start off with smaller doses of fertilizer and sour your way up to full posture for the summer . Based on the plant , I use my liquid fertilizer for my indoor plants anywhere from once a hebdomad to once a month .
It ’s also a good practice to add a dim - release dry fertiliser at planting and again annually . I do this at the beginning of summer .
When summer comes to a close , we want to ease up on fertilizing . Slowly stop fertilise so that by the first frost , you are no longer total fertilizer to your indoor plant . They will remain dormant for the winter and will not require any fertiliser .
Should I Fertilize My Sick Plant?
Fertilizers are necessary for indoor plants to fly high but do not solve all plant health military issue . Some well - meaning plant parent over - fertilize flora because they call back the works has a alimentary deficiency .
If you have a sick plant life , there may be other ground for their way out . Fertilizers only enhance the nutrient , so it will only help if your flora is lacking nutrients . Specific nutrient deficiencies will show up as plant wellness indicator , such as disease , pests , dieback , and discoloration .
Plants can be demented for many reasons . If you have sizable indoor grunge , like this indoor soil mix frommy grunge recipe , then soil fertility is not likely to be the issue . Ifyour plant has pests , yellowing leaves from over - watering , embrown leaves from too much Sunday , or other indicator , plant food will not move as miracle medicine . ensure you know whatproblem your works facesbefore you start fertilizing it like crazy !
