Mirai Forum members report European apical nutrition trials and sap testing

Mirai Forum members opened a horticulture thread titled "Apical nutrition tests in Europe" that began on Feb 6, 2026 and quickly became a forum hub for growers testing apical-style nutrition and foliar or soil regimens across Europe. The conversation is notable for pointing bonsai growers toward lab-based plant sap analysis and pocket testing tools as they seek to quantify nutrition changes and troubleshooting approaches.

Forum contributors highlighted portable testing tools and laboratory services. One post on Bonsaimirai listed "LAQUAtwin Nutrient Meters" and explained that "LAQUAtwin meters are pocketsize meters enabling you to measure nutrient, pH, EC, and salt content in water, plantsap, food and all other water based samples." Multiple short references to "plant sap analysis" appear in the thread as users weigh the convenience of handheld meters against the depth of lab assays.

Members also flagged Eurofins as an accessible European lab option. A quoted forum post noted: "On the UK site of Eurofins they offer something that should give similar results not sure how their service is internationally, the Dutch version offers the same analysis. If you can freeze dry samples shipping won’t be an issue. I would still caution this is an advanced analysis aimed at professional growers that have substrate, water and fertilisation under control. It is not a miracle cure that will solve beginner problems I would only recommend if you have an advanced level of bonsai growing (which based on your youtube you have so feel free to ignore that last part)." A marketing-style line in the thread further advised: "Discover the benefits of plant sap testing in the UK with Eurofins Argo Testing. Get faster results and optimize your crop's nutrition today."

The thread mixes practical advice and questions. Users wrote "Hi, re-starting this discussion. Any luck with finding a lab in Europe/UK? Anyone? Thank you" and asked "Does somebody know anything about it and can provide some info and links to similar companies like Apical in Europe?" One poster signed off twice with "Regards from Serbia." and another referenced "Ryan" when noting that "Ryan mentions that someone is running a similar test to Apical but in Europe." A fragment in the original thread reads "Participants discuss observed effects on shoot vi" but that sentence is truncated in the excerpt and cannot be completed from the available material.

Forum context shows sustained interest in testing and water quality: related threads include "Apical nutrition cost" with 12 replies and 653 views (activity Dec 9, 2024), "Soil testing availability" with 4 replies and 512 views (activity June 15, 2021), "Water PH has changed" with 18 replies and 119 views (activity Aug 19, 2025), "Water testing and what to test for" with 6 replies and 156 views (activity June 25, 2024), and "Garden water pH" in Beginners with 34 replies and 3112 views (activity Sept 4, 2023), with additional rows indicated.

If you plan to pursue apical-style testing, verify that a lab's panel matches the analytes you need and consider the freeze-drying tip for shipping. For quick on-site checks, test a LAQUAtwin meter against a lab baseline before changing your regimen. Follow the Mirai/Bonsaimirai thread for updates, seek clarification from the poster who referenced Ryan, and be aware that some members caution lab sap analysis is geared toward advanced growers with stable substrate, water, and fertilisation practices.
