Possible nitrogen deficiency in spinach

Post  Robbomb116 on 5/31/2017, 3:40 pm

Hello everyone. In trying to figure out why my spinach is so so small even though it has numerous true leaves, my googling has led me to believe it might be a nitrogen deficiency.   Pictured below is one of my smaller spinach plants.  Anyone experience this issue with spinach?  Any thoughts or possible other diagnoses? If it is a nitrogen deficiency, I worry about my other squares as well.  This bed was made last fall and hasn't had anything growing in it until this spring.  Although I did cover the bed with mowed leaves as a mulch in an attempt to encourage microbes to establish in the fall, perhaps the leaves took more nitrogen while breaking down then I expected? PS sorry about the photo being rotated. I know how to fix in by first uploading to my computer but I am just on my phone now.

Some times you just have a plant that is stunted,.  Are all your plants that size and color??  It does not look dark green which would indicate less than optimum nitrogen.

About half are this stunted or nearly this stunted.  Almost all are about this color - slightly yellowish, not dark green for sure.

About 2 or 3 of the 36 are decent size.

Yes, you need to fertilize if a majority look like this or just pull up the ones that aren't thriving.

I would consider adding in some blood meal for long term nitrogen.  It is a nice slow release source.  Won't burn, lasts about the whole season.  

Honestly some of the nutrients do just leach out....

Seems to be I was too late to the game for the spinach.  Even though it's tiny,  most of it is now showing signs of bolting. Harvested what I could. Will possibly add some blood meal. Although the wife is getting annoyed with all these "extra" garden expenses lately haha.  Might have to stay on the down low and just use the fish fertilizer for now since I already bought it.

Yeah, sometimes it will be on sale at the end of the season....I keep it and bone meal all the time.  Rodale is a big proponent, and I really find it is very reliable.  And long acting...I am not particularly attentive to repeat stuff.  

My spinach was really bad this year too.  Bolting under lights (what?) and just really not growing....
