Answer: Planting in 100 degree weather can be stressful on new plants but I think the real problem is that you're not supplying enough water to your palm. With a 1GPH emitter running only 5 minutes a day, your palm is probably only getting a cupful of water. That's not enough to sustain health, especially during hot spells. Leave the drip system running for at least 30 mintues (equivalent to a half gallon of water). Running it in the morning and again in the evening for 30 minutes each time will give your palm a full gallon of water. You can do this every other day and, depending upon the size of your palm, that should provide adequate moisture. If it's a large palm, use a 2GPH emitter in place of the 1GPH emitter.
Hope you can save your palm!
