Newbie needs suggestions for filling in steep slope
Comments (8)> huge bare spots that are ugly and I want to try to unify it and make it look attractive. I wonder why the pine needles aren't forming a (thin) cover. > I think the orange flowers are gazanias?? the clumping type. They'll (continue) dying out. > There is also some rosemary mixed in there. do they appear to be spreading (wriggly branches rooting)? what are the pale scattered things that look about 2-3"? If sandstone, then you could spread a thin layer of more sandstone to help the rosemary spread. _________ For covering purposes, I would mix the species. I don't know socal, but some of these might at least spur better suggestions... Asparagus 'Sprengeri' is pretty good for long seasons and bright shade. Has short sharp prickly hooks on stems. http://www.desert-tropicals.com/Plants/Asparagaceae/Asparagus_densiflorus.html Mahonias would probably settle at the top of the wall. I don't think the drier Mahonias will fill, but could be part of a mix. Dry coastal Salvias or hybrids (S mellifera, etc). They will probably try "running from" shade. Myoporum parvifolium. plain green cover (low shub) Coprosma x kirkii is another plain green cover, but I'm now looking in Sunset.. where they say it's not so dry growing as what i've seen. Maybe the one (or two?) i saw dry were just lucky. They had no competition and were well mulched, so... Erigeron karvinskianus, sort of weedy looking, but dense. they seem to live a long time for a herbaceous-looking plant. Geranium macrorrhizum. whiter foliage, else similar form. i've never grown it. Tough reputation. (but read the sunset description!) Malvastrum, but it will smother anything (such as slow children) in adjoining moist areas. (top of retaining wall is good barrier) Also I don't know how well it hangs on steeper slopes. It likes water but will survive with little water once it's large (which is soon, if watered). Will lose a lot of leaves if dry, showing a lot of stems (it seems to try to smother itself :-) ) Oenothera berlandieri. nice flowers. is a strong spreader (underground), but tends to die out completely. will not stay on a slope. goes to flat ground and swales. will likely go thru that "railroad tie" part of the retaining wall, so don't plant it near there. "Dusty Miller" Senecio(s) or Centaurea gymnocarpa. Won't live very long (on flat ground, but on a slope??), but will grow fast. Senecio wants full sun. Centaurea might grow well under high overhanging pine branches. (still wants sun) spreads/runs irregularly, good in the mix. Lavandula x 'Goodwin Creek' is pretty tough for mostly full sun (mixes ok with similar sized neighbors). Teucrium fruticans. "subtly" charming (bright overall color). won't cover anything densely (is a weak shrub) Mixes well with other shrubs. try Eremophila. Where you can see the flowers. Ballota is tough, though small. I'd pop a few in along top of wall. Socal warm season might be longer than it likes, though. Euryops, though often sheared (!gak!), are very good naturalistic shrubs. Essentially full sun. Acacia redolens. Caltrans tough. Not so great looking close up, imo. More like a thick haze than dense cover. Don't know how well it mixes. There are some larger tough plants. Plumbago. Cissus (vines). Eleaegnus. Tecomaria (you might want to keep the center pushed down.) Large fast Ceanothus (griseus) covers, will do ok in bright woodsy edge. Good in the mix. Research Junipers. Still very tough. I see this sometimes http://images.google.com/images?q=Kabatina+blight Not sure about that in Socal. http://i72.photobucket.com/albums/i199/kates_mommy/BackyardHillside-1-1.jpg What's that thin multi branched treelet? http://i72.photobucket.com/albums/i199/kates_mommy/BackyardHillside-3.jpg And try some "nice stuff" at the top of wall in this area......See MoreSteep slope with Poison Ivy problem
Comments (2)If the area is large, I agree with melissas that you may want to try working on the slope in sections to ensure stability of the slope. This will also make the weed/poison ivy eradication job less overwhelming, and you won't end up with a large bare area of ground to fill in. If the slope is not extremely steep, you might consider starting a rock garden, or terraced type of garden in this area. This will allow easier access to the slope for you so you can weed out any unwanted plants/weeds that may find their way in. A rock garden or a terraced garden will also allow you to work in sections that are separated by barriers from the poison ivy, Pachysandra, and Vinca, all of which tend to be aggressive growers. I would check out the Garden Web's "Hillside Gardening" forum for more ideas on how to plan a garden on a slope at the link below. Good luck! Here is a link that might be useful: Garden Web - Hillside gardening...See MoreWhat to do with a steep slope??
Comments (6)18 yrs ago. wow! well, this is my biggest garden inquiry these days. my side yard of full sun has a huge hill and I want to plant a cut flower garden there. it’s covered in brush and weeds. we have been using it to burn brush around the yard so some of the soil in that burn area will probably be great but otherwise our soil is very sandy and just tested an area and slightly acidic. I am not sure about tilling it. I like the idea of cardboard and mulch and covering with a blanket to keep in place (never thought of the ground fabric to be used like that) however does this method mean I cannot plant this season? sad. It will be progress for sure so that’s excellent. curious if I can, cardbaord and add multch and loam (or maybe just loam) with blanket over to allow for a growing season this year. we have some compost we make but it’s a large area like 43’ high and 86’ long. My hope is the cut flowers will help offset these garden-scaping tasks $$. So, curious what you ended up doing and how it went?! thanks all. Any advice would be great. zone 6a so my growing season isn’t long. I would like to start asap but feel stuck on the route to take, please help :)...See Moreplanting on a steep slope
Comments (6)I have a steep sloping site on the Central Coast and have selectively planted a lot of different natives. In the smaller gaps between the rocks I have planted a mix of native grasses, mainly different Lomandras and Dianellas. As for the grasses, at the base of the slope where it is likely to be damper I have planted L. hystrix, L. 'Tanika' and a few others. As it gets dryer further up the slope, I have planted L.'Tanika'and L. longifolia. I have also dispersed the following shrubs as well; Syzygiums such as S. luehmanii, S. australe "Pink Cascade' and others. These have been planted in areas where there is some residual moisture. You are likely to find residual moisture at the base of the rocks. Further up where it dries out more and there is a bit of sun, I have planted Banksias among the Lilly-pillies, such as B. spinulosa, (which happens to be my favourite) B. ericafolia and a few of the cultivars. Myoporum parvifolium is fine in areas that get limited sun although total shade may be a problem. I find when you plant in areas that provide opportunities for the above varieties of natives you end up with a very attractive natural look....See MoreScott
