I have a pretty steep south facing slope which makes up over half of my lot . It is very hard to maintain because it is so steep but I manage to get down there every few weeks just to check on things. The palms I put on “ The Hill “ are ones that I feel are very hardy and can handle being on their own. Last weekend I went down there to pull a few weeds and take a few updated photos of some of the palms. They are doing well and I was surprised by the health of them , especially my Syagrus Schizophylla. It was fairly young to be planted out but that has never stopped me in the past . Most of these have been down there for over 20 years and were planted as strap leaf seedlings. They have survived gopher attacks , howling Santa Ana winds and driving rain . My irrigation technique is just sprinklers a couple times a week during our arid summers and fall. No fertilizer down there , just survival of the fittest! Harry

‘Looking up you can see there is plenty of available real estate for the right , sun loving , slow growing palms that are not attractive to gophers

‘Just another Washy

A Phoenix Reclinata that will be eventually cut to one or two stems

The newest addition , Syagrus Schizophylla , seems to be doing great 

The ever hardy Livistona Chinensis

Livistona Australis

Brahea Armata, so slow!

The others down there that I didn’t photograph are also doing well Trachycarpus Fortunae , Brahea Edulis , Butia O. , Chamerops Humilis , and a Rhapis Excelsia that I recently divided and planted under the Butia and Brahea. Harry

Looks good!  May I ask, what palm species have suffered bad gopher attack?

The worst , by far is Bismarkia Nobilis. The gophers also ate every Howea Foresteriana that I planted , even with galvanized wire mesh around the root ball. I lost five large ones down there….no more. I lost one Trachycarpus Fortunae. The Sabal has been attacked several times but still cruises along unbothered. I have a gardener that comes twice a month to help with weeds and trap gophers but it is relentless. Neither of my neighbors trap so it’s up to my gardener to try to keep up. Harry

Based on the thickness of the trunk my guess would be Riverside.  Nice palms!  I've got a Syagrus schizophylla about that size that I was considering planting out.  Seeing yours makes me feel better about it.

The Syagrus S. has been in the ground a few months . It gets mostly shade . I was told it should grow into sun as it gets older .but shade while young. Harry

The south facing slope should be a warm spot from near the top to the middle portion.  You'd get some cold drainage at the bottom.

@RFun I have never had frost down at the bottom but , yes , it would be a cold spot for sure. I have Ficus Nitida and Ficus Benjamina for privacy along the bottom. The Syagrus S. is about one third up from the bottom . The lowest ones are the Washy , Phoenix R. , and Brahea Edulis plus a Syagrus R. Queen or two. Harry

Nice little plethora of palms there Harry. Some love gone into them I can see. Syagrus are quite tough palms. Most varieties grow well in my climate some of the new varieties iam interested in seeing how they go in the future of weed potential has put me off a bit.  It schizophylla is a real beauty.
