I've just learned that new houses are being built behind my garden, so I'm on the hunt for trees that can provide good screening. I'm looking for medium-sized trees that aren't too slow-growing and would prefer choices that aren't heavy on pollen since my husband has a tree pollen allergy. I love silver birches, but I'm open to other suggestions too. Our garden is long and west-facing with plenty of light, so I have space for 2-3 trees. I want natural-looking trees instead of hedges, and if they can benefit wildlife, that's a bonus! Ideally, I'd like some native options that won't exacerbate the pollen issue. Any ideas?

Rowan trees might be perfect as they don't grow too big—around 10 meters—and their roots aren’t invasive. They have beautiful seasonal foliage and produce berries that attract birds. I’ve just planted a couple at my place, and they were free since I found them growing along a railway!
You might also want to think about whether you want evergreens or deciduous trees. Magnolia can get quite big but grows slowly. If you’re looking for evergreen options, remember that they can help block some noise and provide year-round cover, but they're usually slower to establish.
I’d love evergreen trees too, but magnolias seem too slow for me. Plus, I can’t stand spiky plants, so I'm steering clear of holly! It's such a tough decision.
How about planting crab apples, magnolia stellata, or dwarf cherry trees? They offer stunning blossoms and are lower in pollen, making them suitable for your situation.

Plus, rowans are native, which is great for supporting local wildlife!
