Transplant Guidance

[windmillcity]

Hi there,

About 17 days ago we transplanted 4 field grown filibustas ranging from 7-10' tall in our backyard--I'm writing to make sure I'm doing everything in my power to mitigate transplant shock and ensure the trees are cared for going into the summer. 

Here are some photos I took this morning. The outer fronds are yellowing and turning brown from transplant shock, but the fronds and growth inside are retaining their green color, which--I hope is a good sign? 

Current process for care: 

• Watering them every other morning for the next week or two (unless the temps go above 100); making sure they get about 6-8 gallons of water
• Planted 2x deep drip stakes per tree ~2 feet from the trunks
• Giving them 1/4 of a cup of Super Moon Juice 1x per week for the first month; then 1x per month after 

My Questions

Is there anything else I should be doing (or not doing) to help them acclimate? It's been extremely windy here (20+ mph most days) and we're about ~30 days out from 3 months of straight 100°+ weather.

When should I untie them? Our landscapers said 3-4 months, but Moon Valley Nursery said 3-4 weeks. I've read the research paper regarding how tying up fronds doesn't really impact transplant shock, so am open to any guidance here. 

Thanks in advance for your thoughts and expertise!
