Mely-rid-me-of-it

Melyridae (Soft-winged flower beetle)

"Mrs. ProfessorRoush is not fond of bugs."  I'm sorry, but that statement isn't strong enough to accurately summarize the situation.  "Mrs. ProfessorRoush hates bugs!"  Yes, perfect, that wording is more descriptive of the depth of her emotions.  Mrs. ProfessorRoush hates spiders and ants and chiggers and ticks and bagworms and generally just about anything that has six or eight legs and gains entry to her home or body.  And she's also not very happy with ProfessorRoush when insects hitch a ride on his flowers into the house.

Thus, we reached a domestic crisis when a number of the creatures pictured here began falling out of every rose bloom that I, her knight-in-shining-armor, so chivalrously tried to gift her.  And as I examined my roses closer, these were everywhere, hiding in the open blooms and running around or abandoning ship at the first sign of human interference or disruption.  The blooms seemed to tolerate these free-loafer tenants without damage, but the bugs were surely putting a strain on the whole "I'm sorry for breathing, here are some roses to make up for it" sequence of my marriage.

Thanks to the Kansas State Extension entomology and their excellent diagnostic service at gotbugs@ksu.edu, I now know that these are beetles in the family Melyridae, also known as soft-wing flower beetles.  They do not, in fact, harm the roses, but are omnivores that primarily feed on other insects and insect eggs, and that sometimes add a little pollen and nectar to their regular diet.  Their larvae live and feed in the soil and there are 520 species in 58 genera of Melyridae in North America.  The "melyrids" as the bug people refer to them, are nuisances to those of us who bring flowers indoors, but they will not eat the carpet or survive long in our homes.  From a fascinating publication titled The Coleopterists Bulletin (2003;57:154-160), I learned that melyrids may even be important pollinators in the western United States, and that my personal melyrids probably visit other flower species as well as my roses.  The author of that article seemed more excited by that discovery than I felt upon reading it, but hey, how much does it really take to excite a coleopterist?

 Melyrids were once recognized as the "Bug of the Week" by someone calling herself "The BugLady," who appears to work for the University of Wisconsin Milwaukee Field Station.  These beetles may contain batrachotoxins, potent heart and nerve toxins that are also found in poison dart frogs in the South Pacific, so I would recommend that you do not make Melyridae a mainstay of your own diet even though you'd have to eat your weight in them to be harmed.  I think I'll keep the latter information from Mrs. ProfessorRoush, lest she begin shaking the blooming roses over my soup du jour.

Regarding my melyrid infestation, I view them as a simple byproduct of my religious conviction to not indiscriminately use insecticides in my garden. If I were spraying the roses with Silent-Spring-inducing poisions instead of allowing nature to find the controls for me, I'd have less melyrids, but also less ladybugs, and I would increase the chance that some insect that the melyrids normally eat would proliferate and cause more damage.  So, I'm going to let bygones be bygones and simply shake out the roses a bit more carefully before presenting them to Mrs. ProfessorRoush.  And hope that she forgives me.   

Buck Rose Blackspot Review

Now that I've seen others state on the Web that it has been a bad blackspot year for their roses, I feel confident enough to come out of the fungal-shame closet and agree that I've been entertaining the same thought.  I don't know if it was the early March warmth or the cool nights of recent weeks, but blackspot has been a struggle at the K-State rose garden at this early date. In my own non-spray garden, I also believed that the roses were a little "fungus-ier" than normal.

So I resolved to note down the degree of blackspot damage on all my roses and did exactly that this morning.  And, you know what?  I think that maybe it is not quite as bad as I thought.  I seem to have been misled by an early defoliation of one of my 'Prairie Harvest' (normally quite resistant), and the damage on my 2-year old Paul Barden rose, 'Jeri Jennings'.  'Jeri Jennings' definitely got  the black spots aplenty, but 'Prairie Harvest' just seemed to turn yellow and defoliate all but the top leaves. I'm still not sure if that was blackspot-induced or drought-induced.  She seems to be coming back.   The rest of my roses are mostly doing quite well, in contrast to my undocumented impression, with exceptionally bad disease only on floribunda 'Rhapsody in Blue', English Rose 'Golden Celebration', and pink floribunda 'Gene Boerner'. 

For reference's sake in this modern era of gigabyte data and online searchs, I will report the blackspot tendencies of three of my rose groups, the Griffith Buck roses, the Canadians, and the Old Garden roses, today and over the next two Mondays.  Today, we'll tackle the Buck roses, at least those roses who are at or beyond their second season with me.   The first number is the estimated percentage of leaves with blackspot and the second number the estimated percent defoliation.  The list, of course, begins with Carefree Beauty, an Earth-Kind® decorated rose and often a resistant control rose in disease plot-tests.

Carefree Beauty 0%-0%
Country Dancer 0%-0%
Freckles 0%-0%
April Moon 0%-0%
Griff's Red 0%-0%
Wild Ginger 0%-5%
Hawkeye Belle 10%-20%

El Catala <5%-0%

I noted roses with "<5%" above when I found a leaf or two with some blackspot, but generally the rest of the rose was unaffected.  The health of most of these roses are not surprising, or should not be surprising for the Buck-bred roses, since Dr. Buck bred and raised his roses under a no-spray policy in a similar climate to mine.  'Prairie Star', 'Quietness', 'Pearlie Mae' and 'Queen Bee' seem to be the only ones that I grow currently with some degree of blackspot present.  Other, that is, than the quandary that 'Prairie Harvest' is presenting me with.  I have one bush almost defoliated and the other unaffected.  I don't know if this year is a quirk from a rose that I've grown for at least 10 years and whose foliage is normally very blackspot-resistant, or whether the rose got damaged from something else like our current drought.  Time alone will tell the me truth.

Heritage of Blooms

'Heritage'

It occurred to me last weekend, and I find it incredibly hard to believe, that I've somehow overlooked blogging about David Austin's 'Heritage' rose before now. 

'Heritage' has a prime spot in my landscape, right out in front of the house towards the right corner, next to the driveway and walkway.  That site is on the west side of the house and she gets a little less sun (maybe 8 hours/day at the height of summer) than some of my roses, but she seems none the worst for the partial shade.  She is about 8 years old, own root, and she's a tall vase-shaped rose (about 6 feet tall) with a lot of presence in the border.  That first bloom, with all those shell-pink delicate blossoms, is a stunner.

'Heritage', or 'AUSblush', has always been a healthy bush for me, with little blackspot and no mildew.  I don't spray her healthy, glossy dark green foliage, but I do provide a little extra water to this bed at the height of summer because it tends to dry out fast with the hot afternoon sun.  She has strong erect canes, never slouching or breaking to the wind, and I commonly go into Spring with between 10 and 15 healthy strong canes on this rose after pruning.  Winter hardiness in my formerly Zone 5B climate was and still is very good, with no dieback noted in most years.


'Heritage' was released by Austin's English Roses breeding program in 1984. Classified as a shrub rose, like many of Austin's creations, she bears light pink, fully double flowers of up to 40 petals that are 4 inches or so in diameter. The flowers are, as advertised, very fragrant when you bury your nose in them, but this is not a rose that I've noticed perfuming the air around it, no matter how prolific the bloom.  I've also found that she doesn't last very long in a vase, but her initial beauty keeps me bringing those blooms inside to stay in the good graces of  Mrs. ProfessorRoush.   She keeps her few thorns to herself (the rose, not Mrs. ProfessorRoush), and is ladylike in her manners, and so she is safely placed near my walkway to the front door.  A tetraploid rose, her parentage is described as a seedling X 'Iceberg'.  Knowing that, I'd like to add that 'Heritage' is a much healthier rose in Kansas, in my experience, than 'Iceberg', who seems to be a better rose everywhere else than here.

I only grow a few English Roses, among which are 'The Dark Lady', 'Mary Rose', and 'Golden Celebration', but so far 'Heritage' would be my pick for Kansas, since the bloom form, hardiness, and health of the bush are more dependable than the others.  It is not an accident that this rose is likely the first that a visitor to my house would encounter. 

Blackberry Bounty

It's Blackberry time here in Kansas!  It's Blackberry time here in Kansas! 

There should be a song written to the wonders of blackberries here in the Flint Hills, a boisterous song to rouse the spirit and whet the palate.  Many fruits are iffy in these dry, thinly-covered hills, but blackberries are usually not among them. The peach crop can be wiped out with an inopportune freeze, strawberries die with the droughts, the watermelons and cantaloupes survive only at the mercy of the squash bugs, and grapes can disappear overnight as the June Bugs arrive, but blackberries, oh blackberries, usually can be counted for a fresh, sweet beginning to the summer.  Okay, maybe except for last year.


I grow a number of blackberries varieties, in theory, but I may be down to one or at most two varieties in reality.  I originally began with a row of thornless 'Arapaho', 'Navaho', 'Black Satin', and 'Cherokee', but those original plants have dwindled with crown gall and I've moved suckers everywhere to grow in other areas, so it's entirely possible that I've ended up with only one of the original cultivars (probably 'Navaho', which seemed the most vigorous) and certainly no more than two of that group.  This year I'm making a concerted effort to provide these thornless varieties some deep watering at intervals (economically, with soaker hoses), in an attempt to improve the number of canes and the harvest.

A couple of years ago, the University of Arkansas released some varieties that fruit on primocanes as well as the floricanes.  Hoping to get two harvests each year of blackberries, I purchased three plants each of Prime-Jim, Prime-Jan (both 2 years old) and Prime-Ark 45 (a yearling) to try.  Of the former two, Prime-Jim seems to be the better variety for the Flint Hills.  It is a thorned variety, but the canes are stiff and erect, not trailing and grabbing at everything in sight like the old classic varieties.   This year, my three Prime-Jim plants have many, many more berries than Prime-Jan, and they are ripening at a quick pace and all at one time.  There are so many berries on Prime-Jim that I don't even care what the second harvest is like because the first out-does any other blackberry I've seen.  Prime-Ark 45, which is said to be the best producer and have the largest berries, is not old enough yet for me to evaluate, and it has been at a disadvantage anyway, putting on most of its current growth during late summer of last year in the midst of a drought. 

I suppose I should expect hybrid blackberries to do well in an environment where wild blackberries grow up everywhere that is not mowed, burned, or otherwise treated, but one can never be sure what evils man may have created during the "improvement process."  Except for a little bacterial crown gall, blackberries are normally trouble-free for me.  In fact, my only problem with blackberries is that I rarely harvest enough of them to use in jam or jelly.  My family tends to eat them off the vine, unwashed, but oh so warm and sweet (the berries, not the family), as fast as they ripen on the canes.  Blackberries stain us, and sustain us, until the main garden bounty comes with summer.
