What are mineral or salt-based fertilizers and how do you use them with bonsai? Eric introduces three different options, explains how to apply them, and offers good advice (plus a blooper at the very end of the video!)
00:00:31 Mineral (also called salt-based) fertilizers are created from mined and refined minerals.
00:01:21 First up - Dyna-Gro! This is a local to the San Francisco Bay Area company. Mineral fertilizers can cause margin burn in sensitive species, and Dyna-Gro claims to be more gentle because it doesn't contain urea. We're big fans and carry Dyna-Gro Foliage Pro in our shop: www.bonsaify.com/products/dyn...
00:02:51 Reminder: always follow the dilution instructions!
00:03:32 Eric offers advice for application for seedlings and younger plants.
00:04:50 Second option - Miracle-Gro, comes in solid crystalline form. It's bright blue color allows you to know you've added it to your water. It's basically a concentrated fertilizer. *We found this offer on the Miracle-Gro website (not an affiliate link) 30% off your MiracleGro.com purchase of $99+. Code: SPRING30 through March 23, 2022.
00:06:56 Eric recommends that you use a TDS meter to check the dilution of your salt-based fertilizers. TDS = total dissolved solids. The meter measures the electrical conductivity of your solution of fertilizer in water. The more salt, the more electrical conductivity. It measures in parts per million.
00:08:02 Third is Osmacote, a granular form coated with a polymer. Eric uses this as a back-up fertilizer "set it and forget it" type of solution because the fertilizer slowly releases through regular watering. Link to the bottle Eric demos with in the video: amzn.to/3u6zSHY
00:10:45 Reminder: bonsai soil doesn't act like standard potting soil, and the nutrients may wash out more quickly. Eric recommends watering at a lower dilution, more frequently.
