Help! My chamaerops humilis is Bowed over at the top, with multiple stunted spears coming out of the crown but none of them opening properly. While searching for pests, Ive found something that I can’t identify in any palm pest sites. On the trunk at the woody petiole bases, there are a lot of random small round brown things that look like a seed or egg. They have very thin shells, and most of them are hollow with a hole (indicating exit of a larva?). I’ve also spotted a few small white squirming larvae buried deep under the petiole bases. These shells are also littering the soil at the base of the tree. What pest could this be? I’ve been trying insecticidal soap. Or could it be a boron deficiency? (Similar spear problems). I’ve been doing a lot of internet research, but I don’t have much real world experience with These. They have been flourishing until the past year.
Has anyone ever purchased this cactus species from a commercial source? It's native to the Mediterranean-climate region of Central Chile. In fact, it grows in habitat with Jubaea chilensis. At the UC Berkeley Botanical Garden it thrives next to burgeoning young Jubaeas, branching at the base to make 6-10' columns. I'm not sure whether they ever sell it at their plant sales.
There aren't many tall columnar cactus whose habitat is such a perfect match to coastal Central California's. I'd love to see it in more gardens around here.
It's common name in Chile appears to be quisco.
Another versatile large columnar cactus that UC Berkeley has is Echinopsis terscheckii, which is available from many growers in California. It's from the Andes of northwest Argentina.
Hello all. I’m a longtime lurker but first time poster. This forum is a great resource, and I’m hoping the SoCal folks here can help me select some palms for their climate.
My brother is purchasing a house in coastal San Diego (Sunset zone 24, USDA zone 10a-10b), and has recruited me to help him install a tropical-looking landscape. I’m very excited to get to grow palms, at least vicariously, in California. Here’s the thing: for a number of reasons, we don’t want to be using a ton of water for irrigation. Also, my brother is planning to move away after a few years and rent the property out. We are looking for palms that, once established, will grow reasonably well (not necessarily fast) without a ton of water, and which could potentially tolerate an accidental dry period if something happens to the irrigation system when he’s not around to supervise the property. I don't know anything about the soil yet, but we're expecting to have to amend it pretty well.
I was thinking that palms originating from Mediterranean climates (e.g. Brahea edulis, Chamaerops humilis, Jubaea chilensis, and Phoenix canariensis) might be more tolerant of summer drought, even if many of these get by in the wild by tapping into subterranean water sources. Washingtonias also seem to do well out there. But what are some more obscure, more tropical-looking palms that could do well for us? Slow-growing species are just fine.
We’d also appreciate recommendations for other drought-tolerant tropical-looking plants (Strelitzia? Wigandia? Ficus petiolaris?), but I know that’s off-topic so I’ll make another post in the ‘tropical-looking plants’ forum.
