what do I use to check NPK I have a PPM meter. sorry i'm new to this just trying to grow
Get your fertilizer read bottle / bag its going to say IE: NPK 10-5-5 10=N 5=P 5=K if your N is lower then other , new fertilizer should be on to do list asap , if not give a nice feeding to her and let her suck it up . NOTE: dont over feed or water or she will die watch her does she look sad= droopy ?
Even if you did use good soil the area around where you put her can and will suck the fertilizer right out of her unless you used a plastic underlayment to stop spread of rood and foreign soil contamination but most people dont do that , should of tested soil and fix the area your working with early in spring if working outside , making sure the area is good to grow in !!!
