I recently added Botanicare Cal-Mag Plus to my plant care routine, and I’m really impressed with the results. The product arrived promptly and was excellently packaged, with no leaks or damage to the bottle, which is always a relief when ordering liquid supplements. From the first use, it was clear that this supplement was high quality. It’s easy to measure and mix with my regular nutrient solution. I started using it a few weeks ago, and my plants have shown significant improvement in their overall health and vigor. Cal-Mag Plus is fantastic for addressing common deficiencies in calcium and magnesium, which are crucial for plant growth. Since incorporating it into my routine, I’ve noticed my plants’ leaves are greener and more robust. There are no more signs of yellowing or other deficiency-related issues. This has been particularly beneficial for my tomatoes and peppers, which are heavy feeders and often prone to such deficiencies. Another great aspect of Cal-Mag Plus is its versatility. I use it for both my soil and hydroponic plants, and it integrates seamlessly with my existing nutrient regimen. It doesn’t cause any imbalances or issues, which makes it very convenient. I’ve also observed that my plants are more resilient to stress since I started using this supplement. They seem to handle fluctuations in temperature and light better, and their overall growth has been more vigorous. The added iron in the formula is a nice bonus, contributing to better chlorophyll production and healthier plants. Overall, I’m extremely satisfied with Botanicare Cal-Mag Plus. It’s a reliable, high-quality supplement that has made a noticeable difference in my plants’ health. If you’re dealing with calcium or magnesium deficiencies, or just want to ensure your plants have everything they need to thrive, I highly recommend giving this product a try. It’s become an essential part of my plant care routine, and I’m excited to see continued improvements as I keep using it.

I’ve been using this product for years, and it has never let me down. Not once have I had blossom end rot on my tomatoes since I started applying it. It simply works exactly as it should, and I consider it a must-have for a healthy garden. My only gripe is the price—it’s gotten pretty steep on Amazon compared to what I can find it for locally. Still, the product itself is five stars all the way. If you’re serious about preventing blossom end rot, this is a no-brainer.

I gave this to my 5 year old Meyer lemon tree and it made it produce the biggest leaves I’ve ever seen on it. This is all while overwintering it indoors in my shower. Notice the smaller leaves on it, those are the normal sized ones. Never seen it do this before! Looks much more healthy after 6 months indoors than previous winters, where it would often drop lots of leaves (they haven’t been dropping much). Admittedly I’ve used a little more than I was supposed to than the directions called for and just eyeballed it. I don’t use it every watering, maybe every 3 waterings or so and make it a little stronger than the directions ask. I also put it on my knockout roses and they went crazy with new foliage. One thing to note, this fertilizer seems to work excellent for new LEAF growth only, not for more flowers or bigger flowers. You have to use different fertilizer for that which I’m not sure I’m allowed to mention here. I’ve got a decent green thumb so I’ve been able to combine this fertilizer with other fertilizers for more roses on my knockouts without over Fertilizing. I never measure, I just eyeball it and they seem to love it. The key here is lots of water and well drained soils. One thing to note, with all of this new foliage you’ll get, you’ll be needing to water much more often and in larger amounts so be prepared to pump up your watering schedules and fluid volumes, especially if it’s really hot outside. In Summary, this is an excellent fertilizer if your plant is well drained but still getting yellow foliage. It will help produce new, abundant and possibly supersized leaves with the right amount of sun, water and drainage.
