What are the signs that I need to adjust my bonsai fertilizer regime?
In my journey as a backyard gardener focusing on indigenous flora, I've always been attentive to my plants' health, but bonsai cultivation has presented new challenges. My indoor bonsai have recently started showing some unusual growth patterns: while some leaves are lush and green, others are smaller and more sparse. I've been using a balanced bonsai fertilizer as per the recommendations I found online, but I'm starting to doubt if it's truly meeting their needs. What are the specific signs I should look for that indicate I might need to change my fertilizing frequency or switch to a different formulation? Any advice from experienced bonsai caretakers would be greatly appreciated, as I'm striving to enhance their vigor!
