Q.Delphinium Leaves Turning Yellow On Bottom
Hi, I recently planted a delphinium for the first time and it is growing nicely with the exception of some of the leaves on the bottom turning yellow. It has budded in the last few days and I recently fertilized the plant in the hopes it would help. But the yellowing continues. Any idea as to what could be going on?

yellowing foliage usually indicates not enough fertilizer. Try adding some compost to the soil since you recently fertilized. Also, keep the soil moist.
