Any water source in your garden is a bird magnet. You can encourage birds to stick around by introducing bird-friendly trees. Now 鈥� during the indoor season 鈥� is the time to plan for spring, so consider which bird trees you might want to put on your winter wish list.

Because there鈥檚 nothing more painful in gardening than having to take down an improperly-sited tree 鈥� and one in the wrong place is a rotten legacy to leave a future homeowner 鈥� consider carefully where to place your tree, and what kind of tree you need. Here鈥檚 where winter gives you a break, because you鈥檝e got time to do your homework.

Shapes and sizes

Is the tree fast or slow-growing? Don鈥檛 be seduced by the promise of instant size. Some fast-growers are fine, but others are weak in branching or possess aggressive roots that can come up in inopportune places around your garden 鈥� I鈥檓 thinking of a silver maple (Acer saccharinum) I once battled. One edition of called that variety 鈥渁 bad actor.鈥�

What will the eventual height look like in your yard? You can get some idea if you figure each story of a house is roughly 10 feet tall. Your own out-stretched arms are approximately equal to your height, so walk around your yard and use your body to measure future diameters 鈥� how far away from that fence should you plant?

Consider size of scale when locating trees, especially near water features. In many cases, it鈥檚 best to stick with smaller-statured specimens. Two notes of caution regarding size. No. 1: Many dwarf conifers are not true dwarfs but simply very slow growing 鈥� some are measured in mere inches of growth per year鈥� but eventually they may outspread the best planning.

And caution No. 2: The labels on larger shrubs and trees often tell you how big the plant will be in 10 years, not its size at maturity. So do some reading in more than one good for a complete understanding of what you鈥檝e got.

Bird-attractive tree choices

Google 鈥渂ird-friendly plants,鈥� and you鈥檒l find a massive amount of information. Here are three of my favorite bird trees to get you started.

Birches are classic around water. If you have the space for these 40- to 70-footers, they look fabulous reflected in a pool, and the small cone-like hanging fruits are a bird treat. However, many varieties are susceptible to bronze birch borer. The American native (Betula papyrifera) is more resistant than the European birch (B. pendula). Usually, however, the weather in the South (Zone 7 and higher) is too warm for either.

And even though the bark isn鈥檛 white, you won鈥檛 go wrong with the (B. nigra 鈥楬eritage鈥�) which is not affected by borers. The mature textured bark is cinnamon-red. For a dwarf river birch (to 10 feet tall), try B. nigra 鈥�Little King鈥�.

I love crab apples, and have planted many in my garden. I appreciate their brightly-colored fruit, which lingers into winter, as well as their early spring blossoms, interesting growth habits and good fall color. Disease-resistant , such as Malus 鈥楽ugar Tyme鈥� and M. 鈥楶rairifire鈥� are good choices.

For elegant and tiny, you can鈥檛 beat the weeping crab, M. Sargentii 鈥楾ina鈥�. At only five feet tall, the tops of its pendulous branches are perfect bird perches 鈥� great next to smaller pools.

Fruiting mulberry trees should be planted well back from water, and underplanted with shrubs that will hide the fruit litter. This tree is messy, but beloved by birds. (The fruit is edible for humans as well.) The American native, (Morus rubra) will grow to 40 feet, while the (M. bombycis 鈥楿nryu鈥� aka 鈥楾ortuosa鈥�) can reach 20 feet with attractive twisting branches. Or consider the six to eight foot drama of a dwarf weeping mulberry with dark fruit to satisfy you or your bird pals.

Next post, I鈥檒l talk about shrubs that give another layer where birds can hang out near water.
