Dago Wisteria

P00607
All this bloom will eventually be fruit.

My colleague down south and I have completely different gardening style. He is a renowned landscape designer, so his home garden is as elaborate as the landscapes he designs for his clients. I am primarily a farmer of horticultural commodities, so my home garden is very strictly utilitarian, with few items that are grown just because they are pretty.

My colleague’s garden is outfitted with a very well built pergola over the patio at the rear of the home. Six common Chinese wisteria were installed to climb the six supporting post and sprawl above. Their cascading spring bloom is both spectacular and alluringly fragrant.

Of course, when I saw that pergola while the wisteria were still young, I thought that it would be ideal for Dago wisteria, which most of us know simply as grapes. They climb like Chinese wisteria. They bloom with somewhat pendulous floral trusses that . . . sort of resemble wisteria bloom. Although they lack color and fragrance, they provide an abundance of fruit.

Now I get to work with some real Dago wisteria. It was planted years ago by someone who did not stay to maintain it. It got rather overgrown and gnarly before I pruned it into submission. Without a pergola, I extended vines from the rail fence that the main vines climb, over to a banister on the upper floor of an adjacent building. It works something like a pergola.

Because I do not know what cultivar of grape the vine is, I do not know what pruning technique it prefers. I happened to leave long canes last winter, just because they reached the banister on the opposite side so well. Now, the bloom is so profuse that I am concerned about the weight of the subsequent fruit pulling the rail fence over!

The Wrath Of Grapes

P91006Jocular reference was made to ‘The Grapes Of Wrath’ on our our backward version on the way to Oklahoma several years ago. We happened to drive through Salinas, where author John Steinbeck was from, and Bakersfield near Weedpatch, where the migration from Oklahoma in the story ended. From there, we literally drove the same route from Oklahoma, but in reverse.

I never read ‘The Grapes Of Wrath’.

I do enjoy growing the sort of grape vines that some of us grow in our home gardens for fruit that can be eaten fresh. (I loath wine grapes and vineyards, but that is another topic for later.) There happens to be a nice big unidentified grapevine at work that needed major pruning last winter. It was a sloppy and formerly unpruned mess, with rampant long canes strewn about.

Some of these canes developed roots where they had been laying on the ground long enough to do so. The process is simply and conveniently known as ‘layering’. It is actually a technique for propagation that is sometimes done intentionally to plants that are not doing it naturally, (Again, that is another topic for later.) After giving a few rooted canes away, there were a few extra.

Since last winter, seven copies of the original grapevine are still here! I really do not know what to do with them. I could give them to neighbors before the end of this winter, but would then worry about them not getting the annual pruning they need, and overwhelming the landscapes they inhabit, just like the original vine did. Even in their cans, they are already a sloppy mess.

Many surplus plants are accumulating here. Many will go into landscapes as rainy weather starts. However, there are a few that will not be so easy to accommodate.

Six on Saturday: Wrath Of Grapes

 

Racial profiling was not likely the reason I was asked to prune a big overgrown grapevine at work. I just happen to be more proficient with dormant pruning of dago wisteria than my colleagues are. My proficiency is more cultural than racial. I am from the Santa Clara Valley, and sadly, they are not.

1. Before pruning, the grapevine was a tangled mess on a split rain fence, which is not even visible in this picture. Incidentally, the forsythia that was featured in ‘Six on Saturday’ two seeks ago is located just beyond the upper left margin of the picture.p90126

2. After pruning, the top rail of the fence is visible, extending away from where the picture was taken. Some of the debris is still piled to the left in the background. Green wires to the right are there for new vines to climb on. The few remaining unpruned vines are layers (stems that lay on the ground long enough to develop roots of their own) that will be dug and removed. I wanted to prune to just spurs, but there were no new canes on the main trunk. Instead, I left stubs of canes from the previous season, with a few extra buds.p90126+

3. This lineup of what seems to be the usual suspects is really seven well rooted layers (the stems that lay on the ground long enough to develop roots of their own that I mentioned earlier) The smallest one on the left is easy to miss.p90126++

4. Most of the layers are very well rooted. We really do not know what to do with the original grapevine. We certainly do not need seven more! Friends and neighbors will likely find good homes for them.p90126+++

5. The weather was so nice for this project, that the ceanothus nearby started to bloom. There are so many other dormant plants to prune before winter ends!p90126++++

6. Just prior to such nice spring weather, we got eight inches of rain from a series of a few storms. This would have been two thirds of the average annual rainfall of twelve inches in my former neighborhood in town! This bucket of rainwater is nine inches deep because it is flared toward the top, and narrower at the bottom.p90126+++++

Proper Bare Root Planting Technique

80124thumbBare root plants are less expensive, easier to handle, and easier to prune into a desired form than canned (potted) plants are. Also, they get established into the garden easier. Yes, even with less roots, they disperse their new roots directly into the surrounding soil more efficiently than secondary roots escaping from crowded roots that had been confined to cans of media (potting soil).

Bare root plants have no incentive to stay confined. They get planted while dormant, and wake up surrounded only by their new soil, with nothing else to get in the way. Canned plants might have been circling their roots within a limited volume of media for a while, trying to find a way out. Once they get in the ground, they may not like what they find there, and try to stay close to the familiar.

Bare root plants should not get too much of a good thing. The need only minimal soil amendment. They might like a bit of organic matter to retain moisture and to keep the soil loose while they get oriented to their new home. A bit of fertilizer would be nice too. Yet, new bare root plants should not get so much amendment that they do not want to disperse their roots beyond the planting hole.

Planting holes do not need to be very big at all. They should be wider than the roots can be spread, but not deeper. Loosing the soil and adding amendments below will cause new plants to sink. Graft unions of grafted plants must remain above grade. Plants with big roots, like fruit trees and roses, prefer their roots to be spread out over a cone of soil in the center of their planting hole.

Most bare root fruit trees are sold with more branches than they need, so should be pruned after planting. Some might get pruned by half. The superfluous stems are there both to cushion the trees in transport, and also to allow more choices for pruning. Some of us want to prune down to lower branches, while others want to prune up to slightly higher branches. Berry canes need very small planting holes, and get pruned back to only two or three buds above ground.P80115

Bare Root Stock Is Here

80117thumbChristmas tree lots at nurseries come and go at a good time. Cut and live Christmas trees become marketable just as retail sales of other items is declining. Although autumn is the best season to plant many things, not many of us want to be out in the garden as the weather gets cooler. As Christmas trees get sold and relinquish their space, bare root nursery stock becomes available.

Smaller bare root plants might be available first, because they can be brought in before leftover Christmas trees get recycled after Christmas. These include grapevines, currants, gooseberries, blueberries, blackberries, raspberries and perennials like rhubarb, asparagus and strawberries. Roses might be included too, but because they are so numerous, they often arrive with fruit trees.

Deciduous fruit trees are the majority of bare root stock. They include stone fruits, pomme fruits, figs, pomegranates, persimmons, walnuts and almonds. Stone fruits are of the genus Prunus, including apricot, cherry, plum, prune, peach, nectarine and almond. Pomme fruits are apple, pear and quince (pictured above). The flowering counterparts to some of these fruit trees may be available as well.

The flowering counterparts are those that are grown for colorful bloom rather than fruit production. Flowering stone fruit trees, such as the famous flowering cherries, produce no fruit. Flowering crabapples produce small and potentially messy fruits. Flowering quinces are actually a different genus than the fruiting types. Most are fruitless. Flowering pears are not often available bare root.

While dormant in late autumn, bare root plants are dug and deprived of the soil that they grew in. They get planted into their new homes before they wake up in spring. Some are packaged in damp sawdust. Others get heeled into damp sand. The advantages of bare root stock relative to canned (potted) stock are that bare root stock is less disfigured, lacks disfigured and circling roots, gets established in a new environment more efficiently, is easier to transport, and is significantly less expensive.
