June 2014 Newsletter

Note from the President- Summer has finally arrived in the gardens.  Winter took its toll on Pace Gardens this year.  Two mature Japanese Maples with trunks too large to wrap your hands around are totally dead.  A multitude of other trees have major damage to them and may not survive the results of the winter wind and sunburn. 

Some plants suffered not from the actual cold but more from drowning during the spring thaw that lasted for weeks keeping the crowns of plants in soggy soil and at times under water.  One of the worst affected species was the Cypripediums.  I lost all but five varieties of Cypripediums and only three of those varieties bloomed this year. 

One thing good about the amount of snow last winter is the thermal insulation it gave to the plants below the snow line.  The Podophyllums, Polygonatums, Trilliums, and many other woodlanders fared extremely well and look great this year.
Our June meeting is at Campbell’s Greenhouse in North Branch.  I want to thank Gene Arms for organizing this meeting.  We will have our potluck, but we will not be allowed to bring plants into the meeting. 

We can also look forward to the July meeting at the Jessop’s who have “Music in the Garden” planned with Steve Prince.  This will be a treat you will not want to miss, so mark July 10th on your calendar. 
I look forward to seeing all of you at our June 12th meeting at Campbell’s Greenhouse in North Branch. 

Next Meeting- Our next meeting will be on June 12th at 6:00 PM at Campbell’s Greenhouse 4077 Burnside Rd. North Branch, MI 48461   Ph. 810-688-3587.  We are going to have our potluck so don’t forget to bring your favorite dish to pass and a chair to sit in.  Please do not bring plants into the greenhouse.  If you have plants with you, leave them in your vehicle.

Summer Alert -Beware

Most reference books on hosta will report that they are quite adaptable to dry shade conditions once they have become established. While this may be true, there is also a practical limit to most generalizations.

During the growing season the hosta rhizome or crown is building reserves that will be used the following spring. Large amounts of water are also required to replace the natural transpiration that occurs with the large leaves. If (as we typically do in the Midwest) encounter a prolonged spell of hot, dry weather, the rhizome will spend reserves to support the plant.

Ever wonder why a hosta appears OK at the end of the year, but appears much smaller and/or less vigorous the following spring, or (even worse) fails to reappear altogether the following spring? This is most likely the result of a decline in the crown mass the previous summer.

So what to do if we do encounter a typical Kansas City summer with day upon day of hot temperatures and extended dry spells? Avoid the stress by watering deeply at least once a week during the summer if we don’t receive any help from Mother Nature. Optimum moisture is reported between one and one and a half inches of water per week during the growing season. This is especially important if your hostas receive significant levels of direct sun exposure.

Watering time is also important. Watering in the morning will help discourage both slugs and fungal activity. Use of soaker hoses works well. When watering blue leafed hostas avoid overhead watering of the leaves which can slowly destroy the glaucous bloom (i.e. the waxy covering that makes a green hosta appear blue). Residual water droplets on any leaf which is followed by sun exposure can also result in leaf burn.

Hostas that Tolerate Dry Shade

Dry shade can be the result of several different situations. The first scenarios that came to my mind were areas that couldn’t be reached by a water hose, gardens that rely on the limited availability of well water, and the areas directly under wide roof overhangs. I was reminded that hosta gardeners regularly experience dry shade conditions due to plantings under trees, most notably shallow rooted trees like maples.

Without amending the soil prior to planting and receiving average amounts of moisture, there may not be any hosta that will grow well year after year in dry shade. This article focuses on hostas that when grown in well prepared amended soil will tolerate dry locations, but not actually prefer this condition. A top dressing of organic mulch (garden compost, mushroom compost or well-rotted wood chips to name a few) will keep the soil cooler, retain moisture longer and reduce evaporation.

When hostas are grown under trees, possibly the most important factor is the type of tree itself. Oak and hickory trees (deep roots) are reasonable to grow hostas under, silver maples are not (shallow roots), at least not without daily care as Lou Holverson does in her wonderful garden. Kay Dye believes that the most difficult area to grow hostas in is anywhere in the vicinity of the outer edge of a tree’s drip line, no matter what type of tree, as their roots are most competitive in this area.

As far as hosta that will tolerate dry shade, Kay developed a list of good performers in her gardens using the following criteria:
§ They were growing in an area that either, is not watered or experiences periods of hotter sun conditions, causing the soil to dry out, even if they do get occasional water.
§ They maintain or increase in size from one year to the next.
§ They are not typically susceptible to crown rot.
§ They look good from August until first frost.

Below is her list, in no particular order. The majority of the following are large hostas. Possibly their tolerance to dry shade is due to a larger root system being more capable of extracting moisture from the soil. An interesting side note, Kay has not noticed any of these hostas form the fairy ring (center clump dieback).

Kay believes these hostas (listed below) actually prefer well drained to dry conditions.

**In Kay’s garden, this hosta has been susceptible to crown rot, but it made the list because it has proven to be “such a trooper in hot dry conditions”.
Keep in mind that the above is Kay’s thoughts based upon plants grown in her gardens. I am sure if you asked other gardeners, there would be some duplication of names, plus some additional names. Ray Wiegand (Ohio) states Sweet Susan, Undulata and Fortunei Albopicta survive in a real dry northern exposure under a roof eave. Additionally, I did find two references stating Jason and Katie will tolerate dry conditions.

Of course, there are no guarantees all of the above will tolerate the variable dry shade conditions in every garden.

Recapping, I think it is safe to say there are hostas that will tolerate dry shade, but to improve the likelihood of success, keep the following tips in mind:
§ Improving the composition of the soil, adding significant amounts of moisture retentive well-rotted composts is critical.
§ Use an organic mulch (not fresh) to retain moisture. It is important to pull the compost a few inches away from the base of each hosta to lessen the possibility of crown and/or petiole rot.
§ A consistent season long watering program will also improve your chances for success.

There are a couple pluses to gardening in dry shade. Slugs do not live in dry locations and the likelihood of crown rot and/or petiole rot is significantly less. Of course, most people would agree there are more severe negatives than positives. These include:

Hostas without sufficient amounts of water throughout the growing season are more likely to develop dry rot of the crown over the winter, resulting in much smaller hostas the following season and possibly the complete loss of others.

Competition for moisture and nutrients from shallow rooted trees is a constant challenge. Hostas grown under shallow rooted trees typically require more watering for optimum size increase. Keep in mind that tree canopies often prevents light rains from reaching the ground. In years of average or more amounts of rainfall, mature clumps of hostas can survive with no supplemental watering. Remember the advice of Bob Solberg; if you are not going to water - DON’T START, if you are going to water - DON’T STOP!
