When is it a good time to plant shrubs and trees?

This is a question I get asked from time to time and like many in my profession, I have my opinions. The criteria I am going to use for ranking months to plant woody shrubs and trees is survivability. Planting a large tree in scorching July heat, for instance, could be so stressful that a tree could perish with less than optimum care. So here are the rankings, from worst to best:

#11 and #12 - July and August - I wouldn’t suggest planting woody shrubs or trees in these two months. July is the hottest month in Central Alabama with an average high of 91 degrees; however, it can be a wet month, averaging a little over 5” of precipitation a month. August might be a little more tempting of a month due to its closer proximity to fall, but with an average high temperature of 90 degrees and it being the second driest month, with less than 3.5” of rain, on average, it is just as unsafe a month to plant in as July is.

#10 - June - Spring has sprung and summer is gaining momentum. Don’t get fooled by a few pretty days. With average high temps of 88 degrees and an average monthly rainfall of 3.78 inches (third worst month), June offers little upside for planting things like forsythia, maple and other shrubs and trees.

#8 and #9 - May and September - Neither is an awesome month to plant in, yet neither is off limits. If the subsequent care (especially watering) of the plants being considered for installation is going to be good, I will plant them. Both of these months average over 80 degrees. September is a slightly drier month than May, but September is closer to fall (a very planting friendly season), so it’s a draw between these two.

#7 - April - I know. I know. That is a month when nurseries are bursting with folks looking for things to plant. Well, there are two things to consider. One, those people aren’t well informed….just kidding, haha. One, many of those people are looking for annuals and perennials to plant and my list is for woody shrubs and trees. And two, April is just two and a half months removed from the summer season. I’m not saying this is a bad month to plant in; it is a good month to plant in, just not the best.

#6 - March - March is a very fine time to plant. With an average high temp of 66 degrees and the wettest month of the year, March is plant friendly. But there are even better months ahead!

#4 & #5 - December and January - I love planting in December and January. These months would be ranked higher if not for the disclaimer I need to provide for them. Disclaimer: I would "consider" excluding plants with a zone hardiness rating of 8 or higher (some examples would be oleander ,pittosporum, or some varieties of gardenia), because of their susceptibility to cold damage. Don't let the disclaimer scare you off, though. Put on your long johns, grab a shovel, and plant your sweet shrub and dogwood, knowing they are loving you for caring enough to find them a new permanent home at the right time of the year.

#3 - October - Why isn’t October #1 or #2? Well, it gets edged out because it can still be rather warm in October and it’s typically a dry month (the driest on average of all the months, averaging just 3.23” of rain). Still, fall has just begun and you’ve got all of this great root growing season ahead of you (fall and spring are the seasons when roots grow the most), plus the mild Alabama winter and then spring greet us before the harsh summer whacks us upside the head. October is a winning month for planting, for sure.

#2 - February - This is a great time to plant. Root growth is occurring. Deciduous plants haven’t leafed out, yet, reducing the amount of transpiration (water loss), which can stress a plant out. Yes, February is a wonderful time of the year for getting in your hydrangeas, magnolias, and other such flora. If not for the fact that February is less than four months away from summer, it would probably be #1. But forget that! It’s a totally awesome month to dig in. Can you dig it?

Ta,,,ta,ta,ta,ta,ta,taaaaaa!
#1 - November - This is the best of all the months to plant in, with February and October following close behind. November features an average high temperature of 65 degrees and is in the top half of rain producing months. The root growth of the plants you are planting will be through the roof and you have plenty of time before mean ol’ summer arrives.

If you notice, the three worst months to plant in are in the summer. Heat does not blend in well with planting shrubs and trees. It can be done, but as you see, there are better times of the year. I really don’t have a problem with any of the other nine months for planting, but some are just a little better or a little worse than the other. It’s Novermber, now, so if you’ve got a little snowball viburnum or Grancy gray beard that you’re think of planting, there couldn’t be a better time than now!
