I am using Mel's mix in raised beds. I have 1.5 beds where I mixed it myself...1/3 compost, 1/3 vermiculite and 1/3 spaghum peat. Then I have 1.5 beds with premixed Mel's (I guess it's licensed from him or something...his pic is on the bag LOL) plus my deep bed also has the premixed Mel's.
The problem? When I water, the surface gets wet and everything just beneath it stays dry. The water then puddles in certain spots and runs down through, and runs off, leaving most of the bed dry. This does not happen as significantly in the areas with my homemade mix but it is a HUGE issue with the area with Mel's mix I bought pre-bagged.
I also have this same mix in some of my container plants and am having the same issue...it pools on the surface and then only runs through in spots.
I think this is why I can't get the seeds I planted early last week to sprout. Radishes should have sprouted by now I think...a couple rogue seeds in the beds that will get properly wet--thanks to my 3yo LOL--have sprouted and have cute little leaves already.
Is there anything I can do other than amending it with more compost (it's already planted with transplants and seeds)? It's so dry here that we're not going to do well as it heats up if I can't get the darned mix wet! I'm so frustrated--between what I mixed myself and the 12 bags of premixed I've bought, this is turning out to be a huge waste of $$!
And I knew better too--just got sucked into the Mel's mix idea last year and felt like I need to finish what I started. I had a nagging feeling the whole time (and people have told me too, some of you here!) that the Me's mix isn't necessary and compost would be a way better way to go. Well, you can say "I told you so" cause you were right...I bought into the commercialism I guess!
I also was planning on getting my SFG certification and wanted to do my beds by the book.
