If April showers bring May flowers then you my friend are in for a “root” awakening. Every April is different which adds to the adventure. I’ve seen 80-degree temperatures and I’ve seen frosts that would freeze the hardiest of plants. I’ve see sunshine and I’ve seen snow. Sounds like a James Taylor song doesn’t it?
Last year we had an early March warm up waking the entire landscape only to freeze in the great Arbor day frost of 2012. So what should we expect from our landscape dreams during the month of April? You my friend are in for a “root” awakening.
April first of all is a big month for lawn care in Michigan. The lawn greens and begins to grow and we welcome the sound of lawnmowers awakening in our neighborhoods.
A great month to get a deal on a 4 step lawn plan applying the first step now and storing the remaining 3 steps in the garage or shed for applications later in the year. The first feeding generally includes a crabgrass control which is important after the hot year we had in 2012. Crabgrass seed from last year over winters in the soil of your lawn and will wake and germinate when soil (not air) temperatures get to be around 60 degrees or warmer.
If you don’t have a soil thermometer, which most people don’t, you can listen to me on my radio show or you can use the old fashioned less scientific way of gauging spring’s wake up call.
That would be to act when the forsythias are in bloom or apply sometime around tax day. Certainly much easier for you than having to understand the methods of “growing degree days” that us horticultural people like to track at this time of year. Applying a crabgrass control in spring, especially in the hottest areas of the lawn like driveway or sidewalk edges or non-shaded areas will create a barrier to germination so you don’t have an infestation of unsightly crabgrass come the heat of summer.
April includes Arbor Day which here in Michigan falls on the last Friday of the month. April is a great time to plant a tree or landscape shrub. We see many trees show off in April with Crabapples, Redbuds, Juneberry, Magnolia and Cherry trees to name a few. This month is perfect for planting evergreens and woody landscape plants, saving the more tender plants for May when frost is less of a threat. Remember that when it comes to “tender” plants a great frost tolerant plant for some early April flowers in the landscape would Pansies. In regards to tender foliage, keep some deer repellant handy and make sure to apply to susceptible plants during the month. Hungry deer after winter are anxious for a buffet of tender green growth including delicious Tulips and Hosta. Not tonight “deer.”
Understanding the weather can be a variable and tricky issue in April, it is a good month to work on soil preparation, planting bed preparation and some mulching. You don’t have to protect dirt and mulch from overnight frosts. Raised planting beds soil warm quicker in spring. If you’re itching to plant some herbs, pot up some containers and move them in and out contingent on weather conditions.
In regards to mulch, many will apply because it looks nice. True, but there is a functional use for mulch too. I saw a study that described the impact an appropriate layer of 2 inches of mulch can have for your landscape when the heat of summer does arrive. In this study on a San Antonio Texas day where the air temperature was 105 degrees and in the sun felt like 130 degrees, the bare soil was 102 degrees, the soil under the grass was 92 degrees and soil under 3 inches of mulch was 76 degrees. That gives you an idea of the soil temperature regulating benefit of mulch as well as its ability to hold moisture in the soil.
Let’s get out there and get “growing” now that winter is finally over. You my friend are in for a “root” awakening.
