roystonea regia growing slow. something wrong or just transplant shock?

[sdpalmgabe]

Hi all - I'm very new to this so apologize for the newb question.  I bought a pair of nice looking r. regia from @Joe palma and planted them about 6 weeks ago.  I planted them in full sun in my yard which is west-facing and on a big slope - I'm about 10 miles from the coast in San Diego.  They look... fine. I've been watching the spear-growth since planting and it seems to have slowed down in the last few weeks, which is what worries me.  Shortly after planting it was probably ~1 cm/day and it has since slowed to maybe 1mm/day.  My question is: should I react and try to change anything? or is this just some combination of transplant shock or the fact that it just started getting hot here in the last 3-4 weeks.  My instinct is that I should just give them a few months to establish and adapt, but whenever I read posts here talking about how they're rockets it makes me worry that something might be wrong.  Thanks for any advice.  Here they are before planting and one in the ground yesterday.  They're getting watered 3x/week for 30 minutes on a drip-line and when I dig into the ground nearby it feels moist but not wet

these need ALOT of water.  2hrs trickle a day every day for a month then every other day as long as its warm out(>80 high).  Im sure some Socal experienced board members will give you even better locally tailored advice.  These are water hogs, I hope your soil doesnt drain too fast.

Very common problem. Give them the first year to adjust, and then they’ll be on their way!

Some good advice here . I am north of you , about 20 miles inland . My Roystonia Oleracae ( I know it’s different) was much smaller when I planted it and it is more cold sensitive than Regia but it took months for it to start growing well. I planted it in partial shade so it could grow into more sun as it gained height. It did well for over 20 years but never really looked that nice . Smaller fronds for its size and not really good coloring. I read on PT how Roystonia LOVE water. I gave it some organic fertilizer and just watered the heck out of it almost every day. It now is much more presentable. The fronds are at least double the size they were. Last year was the first year it got 4 new fronds . The folks here were right and I listened . Now I have a better Roystonia as a result. For a palm that is not well suited for my environment , it looks pretty darn good. Harry
