OK, you have the plants & you need to get them in the ground. Raspberries take up quite a lot of room in a sunny area. They can get out of control quickly & grow long swaying boughs. I tried growing 4 in about 10 ft. by 3 ft.area, not nearly enough space & not full sun so I ended up taking them out after a few years. Strawberries like a lot of sun but can probably take a little shade(in So. Ca. anyway) don't bury them deeper than they are in pot. They spread by runners next summer so figure out your bed so it is easy to get to plants & from all sides to pick berries. Lilies spread so if you are tied up with kids or getting older might want them somewhere so if they multiply it won't ruin your garden if you don't get to them each year-they like lot of sun.They are most attractive when several of 1 color are clumped together. Iris don't like being messed with until divided. Lily of Valley like lots of shade as do most Hostas. Sort out your plants by area they need to be in,then arrange them in their pots until they look right, keep your veggies separate from other plants & try to keep your herbs in a bed by themselves, chives, oregano, onions,etc, they get messy & might put parsley around outside edge of this bed to make it more interesting. Get some graph paper & start planning on paper so you know where you will have trees how much shade they are going to give & if they can have shade plants under them. Get your sunny areas figured out & that will be area for veggies,berries, herbs,if you are planting corn,peas, green beans, squash they take up a lot of room so you will have to cut back on shade. If there is nothing behind garage & a space back there in shade you can make that your lily of valley area & break it up bit with couple of hostas. You don't want your garden & yard so much work you don't get to enjoy it. Digging out the lawn to put all this in will be lot of work so have to make it more manageable.If you want paths you need to include them. Need place to sit & relax & have friends over so you can enjoy fruits of your labors.If your library has Birds & Bloom magazines, there was lovely evolved garden in there some months ago. All gardens evolve as years go by, you find what works for you. The perfect spot at your neighbor's 2 doors down may get you O results at your place so lot of it is trial & error.I love rhubarb, planted it & it was going crazy,hanging over in lawn so I moved it,never have found a place that works since. I had planted a lovely peace rose there I don't have any rhubarb now. It doesn't like wet feet. So you may have to move plants that aren't happy anyway no matter how you plan it out. Good Luck!

It's obvious you are a very loving & responsible doggie owner and that's wonderful! I have 2 dogs that play in the yard everyday and only recently learned that my aloe vera, Azaleas, Hostas & cyclamin, Chrysanthemums & Ivy are toxic to dogs, yet I've had them in the garden for quite some time. My next door neighbor has an avocado tree that hangs over into my yard and it has never been an issue. My biggest worry mushrooms! But as far as a screen~ I'll chime in with my suggestion~ Dodonaea viscosa cv. purpurea (Purple Dodonaea). You can almost plant it and forget about it. They are evergreen, very drought tolerant and fast growers and do well in our zone. They can get really tall & wide but not invasive at all. They need to be kept pruned (about once a year or every other year)for desired size & shape and to look their best when they get older, but are super easy to prune since the branches are spread out. A few cuts and your done. I think it would be nice for a cottage style as well because they are very informal looking. Just make sure you don't plant them in an area where you have other plants that require a lot of water because over watering will kill it. I have one in a long deep planter that's built in to my deck (approx. 3'deep x 8' long x 12" depth) and give it about 2-3 feet around the roots where I don't water as frequently as I do for plants at the other end of the planter. If you dont like the purple, there is also the green variety. Here is a link that might be useful:

I think you need a clumping bamboo that maxes out at 15 feet. Or how about mcarthur palms under planted with tecoma stans or some other pretty drought tolerant flowering shrub?

you dont have room for multiple trees .. as per your title ... do you have patio furniture yet.. a table with an umbrella.. might do what you want done .... also.. by the time you sit down... you shouldnt see past the fence ... i guess i am suggesting you get the patio set.. and see if and how that changes your variables.. before choosing the plants ... ken
