Triumphs and defeats in the garden so far this year
Comments (10)It's still early in the season here. Pruning, otherwise known as Me vs. The Garden is still progressing. Sort of. At this point, I've done all the 'easy' roses. The ones that go snip, snip, snip. What's left are things like Queen of the Prairies and Clair Matin, the ones that need saws to cut out old canes that should have been cut out years ago, except that I never bothered to get the saw out of the garage. The early roses have started blooming. R. hugonis, R. primula and Glory of Edsel. The lilacs are in full bloom, the doublefile viburnum is turning white, and the first of the tree peonies are opening. The early iris are fading, so it's time to anxiously await the opening of the first TBs. The bloom stalks are there, the flowers are starting to show color, but are at least a couple of days away. Having drastically redone irisdom a couple of years ago, I'm refusing to mess with the bed until it starts crowding. The result is a bigger and better show every year. This is the way it's supposed to work, but doesn't always. People are starting to drop hints about garden visits. That means it's time to start taking the quarry work seriously again. Most of the beds are dug to about a foot, then amended. Since we start with heavy, rocky soil, the result is quite good rose soil and a pile of rock. The exception has always been a relatively small area with bedrock near the surface. It started off garden life as an iris bed. The small, early iris species that were placed there didn't mind the almost total lack of soil. It was close enough to their native habitat. But over time, as the garden vision changed, it was thought desirable to have a deeper bed as a more normal extension of the rest of the garden. So the rock had to go. The rock is still going, and the excavated topsoil still sits on a tarp in the middle of a garden path. I refuse to even think about how many years this has been true. Last summer, I got the hole to a point where there is deep enough soil for most things. However, the hole produces about the best paving stone I've dug here. Paving stone has uses, and if I don't dig it out of that hole, I'll have to *horrors* BUY it....See MoreSelective Breeding for Cold Hardiness ?
Comments (25)Since then I've been reading about cold hardiness. It's not simple: Trigger the dormancy process. Some plants do this on temperature, some on daylight. Both have slop, and are themselves multigene operations. A plant in Virginia may have 2 months more nice weather at the fall equinox, where here in Alberta, the first killing frost has probably already happened. Water removal from tissues. While you want the plant as a whole to go into winter well hydrated, many plants winterize by pulling water from their cells. This leaves a stronger solution in the protoplasm that has a lower freezing point. This confers 10-20 degrees of frost protection. Antifreeze in the tissues. Some plants mak alcohols and glycols. These further lower the freezing point, and interfere with the creation of ice crystals. Protection of buds. Not only is winter cold, but long. Buds can dehydrate to the point of being non-viable. Sunny days just below freezing are the worst for this. The roots can't supply water that warmer temps pull out. This does in cedars, particularly ones on the south side of the hosue. My feel is that you can probably breed 2-3 zones colder with patience and interspecies cross breeds. But if you can find a member of the genus that has the trait you want, and will produce a non-sterile hybrid you have cut a job of centuries down to mere decades. The creation of northern apples is one such story. U Saskatchewan's work with hardy sour cherry is another. The cold tolerance comes from a mongolian pea cherry with tiny fruit that taste awful. Cross it with a decent cherry. Cross the off spring. Select for cold hardiness and taste. Repeat....See MoreBluebirds returned, didnt nest, now they'r back 6 wks later.
Comments (8)You removed a Chickadee nest?? Why on earth would you remove a Chickadee nest?? They are very low on the totem pole as far as successful nestings since they cannot fight off larger cavity nesters, plus they usually only have one brood per season so they need all the help they can get. I LOVE Dees! I have had them nesting here for the last three years and I would never never remove one of their nests!! I protect them as much as I could and if a Blue pair wanted the box that a Dee already had then I would put a hole reducer on the box so the Blues couldn't have it! I have tons of TRES that take all the boxes around here but I haven't removed any of their nests either, just keep hoping the Blues find an empty box and nest. The Blues around here are always the last to start nesting so they get what is left pretty much of the nestboxes. I have one pair of Blues, one pair of Dees and six pairs of TRES all nesting right now. Blues love mealworms but as far as getting them to stay in your yard and nest, there is no guarantee. The male finds the nesting sites but the female needs to approve of it. She makes the final pic. If she likes the nestbox she will stay...if they found something better elsewhere they will go there. Alot depends on the availability of nestboxes around your area. If they have lots to choose from they could go anywhere but if there aren't alot of spots for them to choose from then maybe they will choose your yard. However if you aren't prepared to let other native cavity nesters use the nestboxes you put up then you shouldn't be offering nestboxes. Oh and hopefully all your nestboxes are mounted on slick metal poles (conduit works best) with predator baffles and at least 15 feet away from trees or fences.

Comments (154)Herman, thanks for the update. It’s great to see fruit already. How large are the Conestoga 026 Segentrange and Poncirus Plus fruit? They look similar to PT…….or are they larger…….photos can be hard to judge. Great to hear 5* Citrumelo has some sweetness. Fruit ripens around Thanksgiving……but the size is clearly larger than PT…….a nice selection. Getting fruit in 3 years is very fast. I gave my brother who lives in Fairfax, VA a seed grown Citrumelo 12 years ago and it still hasn’t bloomed! Keep the updates coming....See Moreroseseek
