Excellent Balanced Fertilizer for Cycads
I’ve been using Jack’s Classic 16-5-25 Tropical Food on my cycads, and they’ve really responded well to it. The NPK ratio seems perfectly suited for strong, steady growth without excessive softness or weak new flushes. I apply a diluted dose with every watering, and the plants have stayed consistently healthy and vibrant. One thing I especially appreciate is the diversified nitrogen sources—ammoniacal, nitrate, and urea. That mix provides both immediate and sustained nutrition, which keeps the growth balanced over time. It also dissolves cleanly and doesn’t leave any residue in my watering cans or pots. Another big plus is the inclusion of micronutrients, which helps ensure the plants get a complete, balanced feed—especially important for cycads that can be sensitive to deficiencies. Overall, this fertilizer has become my go-to for maintaining lush, healthy cycads. Highly recommended for anyone looking for a professional-quality, well-formulated feed.

Wonderful for my majestic palm
The Palm food came just in the nick of time! I live in the northeast so my palms enjoy summer outdoors but must winter indoors. They seem to do well until the months of March & April when their leaves become dry and brown. I actually wrote the manufacturer (the company is out of PA). They explained that the air gets severely dry in March & April so low humidity causes that dryness. Suggested I use a humidifier in the spring indoors until I can get them outside. They also explained even though my palms are in pots, to give it the outdoor plant dosage once I get them outside. My palms perked up almost immediately in early summer when I gave them their first feeding. They've grown all new fronds and are so healthy now. No more dropping leaves or yellowing. This food is exactly what your palms need!

Love me some Jack's
I always buy Jack's because it's the best imo. my plants are all lush and beautiful. Also use the tomato one. The only reason I give it a 4 star is because the lid came off and there was a hole in the plastic so some fertilizer spilled out. It wasn't much. I've never had this issue before. Maybe start taping the lid down?

Essential
I have a majesty palm. I knew it needed an appropriate fertilizer but put off finding one. Some of the fronds started to die off in the winter and it wasn't looking healthy on the other fronds at which point I ordered this. Been using a small amount with each watering and the palm is doing a lot better. I put a small amount of fertilizer in an old yogurt container, add an inch or so of water, mix it by swirling, then fill it up with more water. Been easy to use that way and I'm glad I bought it.

Works well with Sylvester Palm Tree
Used Jack's Palm Food on my Sylvester Palm even though the label does not mention that it works with Sylvester. Noticed an improvement in the first 2 weeks. Now been 2 months in Florida spring and it looks better and better. Easy to apply, I have no complaints.

Happy Palms
I've only given one "dosage" to my palms and they are all springing to life!. I have a variety of Kings, Sagos, and Pygmy's. The King's especially struggle to stay green. Normally the new fronds start green and turn brown and dry. 1 month ago I fed the palm's the recommended dosage: 2 scoops to 2 gallons water. I haven't had time to give them a second feeding but they are still "happy" and green. I did water the day before so the ground would absorb the feeding better. Highly recommend this product. Well worth the expense for what you get: new growth and green happy palms in a few days!!!

My big palm tree seemed a bit depleted so bought this on Prime Day... I've used it twice and it's easy to use... it looks a lot like those blue Miracle Grow granules and mixes with water easy... Hopefully this will help my palm get healthier!
