The Pros and Cons of Late Season Snow

SNOW  or  SNOW  ??

At Harlequin’s Gardens we often tell customers that “Mid-May / Mother’s Day is our average last frost date.” The most important part of that sentence is “average”, and we remember a year when we experienced 23 degrees on May 24th. This week’s freezing temperatures and late-season snow were a surprise, presenting challenges and opportunities.  Challenges for the tender annuals and warm-season veggies that were recently planted (we hope that you were able to protect them with Solar Caps, Row Cover, or over-turned planting pots lined with bubble wrap).  Eve recommends our heavy duty tomato cages that really support the plants, and also can be used now to support tents of Row Cover or other fabric for quick protection from late snow or impending hail.  She especially likes the ‘inverted’ cages, which taper from a wide base to a smaller diameter top.  As a note, most annuals usually recover rapidly from snow breakage. 

If you recently purchased tender plants and haven’t yet planted them, it’s best to keep them comfy indoors and then begin hardening them off when the weather warms up again.  (See below for our Hardening Off Guidelines.)  But of course the snow and rain are providing much-valued moisture to our region, which is appreciated.  We can celebrate the wonderful delivery of free water!   Our native plants and those from similar regions, such as steppes (Siberia, Central Asia, etc.) are better at dealing with these weather events than non-regional tender.  

As a reminder from Arborist-Mikl, if you’re knocking the snow off of your shrubs, trees, etc, to be sure to do it by lifting the limbs from underneath as beating snow off from the top can cause branches to break.  If you do suffer a ragged branch break, give it a clean cut  as soon as you can.  

We have begun brewing compost tea, which is available by the gallon jug (bring your own or ‘rent’ ours for $1).  Compost tea is a great boost for struggling plants and to use on new plantings. 

While we have a Memorial Day weekend without classes, come June 1 and 2 we’re featuring three very informative classes beginning with co-presenters Kristina Williams and Mikl Brawner on the topic of “Japanese Beetles”, Saturday, June 1 at 10 AM.  Though it may seem early to begin thinking about this recent invader, NOW is the best time to begin building your defenses against them.  That afternoon at 1:00 PM, Kelly Grummons will introduce you to “Dog Tuff™ Grass”, a hardy, warm-season, sun-loving turf grass that requires just a fraction of the water of traditional turf grass, and only occasional mowing.   On Sunday, June 2 at 1:00 PM, Mikl presents his popular “Berries and Small Fruits for Colorado” class.  

Further class details are listed below and as always, please call to register:    303-939-9403

HARDENING OFF GUIDELINES

Transitioning tender annuals, vegetable, and other plants, from a cushy greenhouse setting to the outdoors is essential to getting them established.  Hardening off means to gradually acclimate plants to outdoor conditions prior to planting.  Plants grown indoors or in a greenhouse are not accustomed to the wind, sun, and other conditions they will encounter outside, and could freeze, dry out, or burn.

To harden off your plants, begin 5-7 days before transplant date.  Place the plants in a sheltered, shady spot outdoors.  Leave them for about 2-3 hours the first day, then gradually increase the time spent outside by 2-3 hours each day.  By the third day, try to add several hours of morning sun to the outdoor time.

Bring the plants back indoors each night, or if the outdoor temperature is below 45 degrees.

After the 5-7 day period, your babies can be planted in the garden! Be aware of weather conditions, though, and be prepared to cover the plants if inclement weather (snow, high winds, or freezing temperatures) is expected.
