Q.my plants come up well . But when they reach about 6″ they grow very very slow.It takes a long time for them to produce. Any sugg
estions? I have a soil test done every year. My ph was at 8.2 so I added sulfur to correct it last fall. Would the ph cause the slow growth?

Yes, that pH is way too high for any plant to survive. Did your soil test, also, reveal really high levels of potassium or phosphorus? This will cause a high pH. I would offset with some nitrogen. Iron sulfate will be a little more effective at lowering the pH as well.
