Seeing your photo it looks like the plant needs to be repotted into a larger pot with new soil and especially since it's obvious there is a large and elderly portion of this plant sharing the space of the smaller soil level leaves. It's simply in a very small pot just sitting inside a larger pot. The size of the existing larger pot would be perfect so just get enough new soil that will go up to the line you see inside that pot ... It's most likely root bound and crying for more room now in the small pot and needs new soil that has some fresh nutrients. When you repot be sure to gently spread the existing root in the ball out a bit so the roots can easily spread/grow and breathe. Make sure the new soil is very moist (not flooded) when you first repot. Potted plants should be repotted at least every other year.
Does Epsom salt affect plant growth?
By Madison from Sumter, USA
Epsom Salt is the same thing as magnesium sulfate. If you have yellowing between the veins of leaves from the bottom up on your plants or your plants lack vigor, adding this element may help. Mix one tablespoon per gallon of water into the soil. But don't over do it because it can tie up trace minerals by reducing the absorption of Calcium and Potassium. If you have alkaline soil also add one tablespoon of vinegar to the water. Tomatoes will do great if you add this when you plant them... just sprinkle some in the hole before planting.
We have had a lot of rain recently and now my vegetable garden including my corn is getting light green to yellow. Is there something I should add to the soil?
By MaryS from IN
Yes, check garden center for liquid iron or some other brand for it. You have washed nutrients out of the soil. You see this a lot with container planting.
