Bare Root Stock

Bare Root Stock may not be much to look at.

Now that nurseries and garden centers are no longer selling Christmas trees, they have plenty of room for bare root stock. All sorts of deciduous fruit trees, a few deciduous shade trees, shrubs and vines, and even a few perennials can now be purchased while dormant and without the cumbersome media (soil) that the roots need at all other times of the year. Not only is bare root stock easier to handle and transport in small cars, but it is also much less expensive than canned stock (that has roots contained in media, which is contained in nursery cans). Bare root stock typically costs about a third of what canned stock costs.

Bare root stock also has the advantage of adapting to new garden easier, since it does not need to leave the comfort zone of the media that it would have grown into (within a can) in order to venture out into unfamiliar soil. Instead, it starts to disperse roots into the new home soil immediately as it emerges from dormancy in late winter. Without cans, bare root stock can not get root bound. Instead of developing branch structure that is appealing to nursery marketing, bare root stock can get an early start on developing branch structure that is most practical and efficient for the gardens that it gets installed into.

It seems that all of the ´stone’ fruit can be found as bare root stock. These include apricot, cherry, plum, prune, peach, nectarine, almond (which is the seed, or ´stone’, of a peach like fruit) and the odd hybrids of these. The pomme fruits, apple, pear and quince, are perhaps the second most popular of bare root stock, although quince is still rather rare. Ornamental trees, shrubs and vines include flowering crabapple, flowering cherry, flowering quince, alder, poplar, willow, lilac, forsythia, wisteria and clematis. Perennials include rhubarb and artichoke.

Bare root stock can be purchased as soon as it becomes available, but does not do much until it starts to grow in spring. It should get planted quickly and soaked in, but will get more water than it needs from rain afterward. It should not need water again until after it blooms or gets new leaves in late winter or early spring. Despite guarantees of fruit in the first year, none should be expected. The few fruit trees that might set fruit will probably produce only useless underdeveloped fruit because new plants are busy producing new roots and growing. Actually though, this apples to canned stock as well, except only for citrus, olives and other evergreen fruit trees.

Persimmon

Persimmons ripen as their leaves fall.

It lacks the spectacular spring bloom of the other deciduous fruit trees, but compensates. Persimmon, Diospyros kaki, performs double duty with fall color. Its autumn foliar color is impressively fiery orange. Then, it defoliates to reveal plump, abundant and comparably fiery orange fruit. So, it is spectacular with both autumn foliar color and autumn fruit color.

Persimmon trees are tempting. Some cultivars can grow twenty feet tall to become small or even mid sized shade trees. However, if they do so, much of their overly abundant fruit is unreachable. Aggressive and strategic pruning limits their production with most of their fruit in reach. Although undemanding otherwise, this major dormant pruning is important.

Persimmons are self fruitful without a pollinator. However, they supposedly provide more fruit of better quality with another cultivar. Fruit is unfortunately inedible before thoroughly ripe, but then all ripens simultaneously. That is an incentive to share with neighbors and friends. With a bit of effort, fruit is conducive to drying and freezing, although not canning. Ripe fruit is very perishable.

Bare Root Stock

Dormancy makes this process possible.

As soon as any unsold Christmas trees move out of nurseries, bare root plants move in. Like Christmas trees, bare root plants are available within a limited season, while they are dormant through winter. They will all be gone by the time they start blooming and producing new foliage at the end of winter.

Bare root plants of course have ‘bare roots’, without typical media (potting soil) contained within cans or pots. Some get their roots wrapped in lightweight coarse sawdust to keep them moist without too much bulk. Others get their roots heeled into moist sand in nurseries, so that they can simply be dug when purchased.

Because bare root plants need much less space than canned (potted) plants, many more different kinds of deciduous fruit trees, roses, grapes, berries and even a few ornamentals are available. Bare root plants also cost about half as much as typical canned plants.

Since no nursery can stock all of what is available, more varieties are available from mail order catalogues and online. Most of what is available in local nurseries is selected for local climates. Plants purchased from catalogues or online need to be selected accordingly.

A main advantage of bare root plants is that they get established in the garden more efficiently than typical canned (potted) plants do. They get dug, transported and replanted into the garden all while dormant. By the time they wake up in spring, they are already in their new home, where they immediately adapt and start to disperse their roots into relatively uniform soil. Canned plants have confined roots that must disperse into unfamiliar garden soil

Bare root plants should get into the garden as soon as possible. If they do not get planted immediately, plants that were pulled from sand in nurseries should get heeled into damp soil or mulch, and watered to settle the fill. Alternatively, they can wait with their roots in buckets of water for a day to two. Bare root plants that are wrapped in bags of sawdust should be safe for more than a week in the shade outside.

Planting holes should be just large enough to accommodate the roots. If too deep, the loosened soil below is likely to settle and sink. Soil can be mounded into a small cone (known as a ‘volcano’) in the middle of each hole to spread roots over. Graft unions (seen as kinks low on trunks of fruit trees or where rose plants branch) of grafted plants should stand above the surface of the soil. Backfill soil should only be amended lightly, if at all.

Even though dormant plants get more moisture than they need from rain through winter, freshly planted bare root plants should get soaked twice immediately after planting to settle the soil around their roots. Lastly, damaged or superfluous stems can be pruned off. Most bare root fruit trees have much more stems than they should for padding in transportation and to allow more options for pruning.

Bare Root Stock

Bare root stock is none too pretty in the beginning.

Now that Christmas trees have been moved out of the nurseries, it is time for bare root plants to move in! As the term implies, bare root plants have ‘bare roots’, lacking typical media (such as potting soil) which is typically contained in cans or pots. All sorts of deciduous fruit trees, roses, grapes and berries can be purchased bare root, either bagged with moist wood shavings, or out of the ‘sand boxes’ that they are heeled into in the nurseries. Even more are available from mail order catalogues. (Just check climate zone ratings for mail order stock.)

I purchased all of my deciduous fruit trees bare root mainly to save money. Bare root stock typically costs about half of what canned stock (grown in a nursery can or pot) does. Also, because bare root stock does not take up as much space as canned stock does, more varieties can be brought in and made available during bare root season.

Bare root stock gets established into the garden more efficiently than canned stock does. It gets dug, transported and planted while dormant; and can disperse roots into relatively uniform soil immediately after dormancy. However, stock that gets canned wakes up in spring in uncomfortably warm and confining nursery cans. After adapting to nursery conditions, it must then adapt to new garden environments, and disperse roots into soil that is very different from what it already rooted into.

Bare root stock should be planted as soon as possible after it leaves the nursery so that roots do not get too dry. If they can not get planted immediately, plants that were pulled from sand boxes in nurseries should get their roots heeled into (covered with) damp soil. Bagged stock in original packaging is safe for a few days in the shade.

Roots should be soaked a few hours before planting. I prefer to instead keep roots well watered for a day after planting. Broken or damaged roots should be pruned away before planting. Damaged and superfluous stems should be pruned away after planting.

Planting holes for bare root stock can be wide enough to loosen surrounding soil, but should be no deeper than necessary. Plants are likely to settle too deeply if the soil below is too loose. All roots should be buried while graft unions (the odd ‘kinks’ low on the trunks of grafted trees) remain exposed. Soil can be mounded firmly into a ‘volcano’ in the middle of each hole to spread roots over. Backfill soil can be amended lightly; not so much that it is too different from surrounding soil.

A basin should be formed around each new bare root plant so that roots can be soaked and settled in by filling the basins with water twice. Bare root plants are initially dormant and lack foliage, so do not need water again until they develop foliage, and the soil gets dry in spring. Besides, rain and cool weather will keep the soil wet through winter.

Bare Root Begins As Christmas Ends

Winter Is For Getting Bare

Bare root plants do not look like much . . . yet.

Even before the last of the Christmas trees vacate nurseries, bare root nursery stock begins to move in, and will be available through winter. As the name implies, ‘bare root’ stock has bare roots, without media (‘potting soil’) or cans (pots) to contain the roots. Many are temporarily heeled into damp sand from which they get dug and wrapped in newspaper when purchased. Others are packaged in damp wood shavings or coarse sawdust contained in narrow plastic bags.

Bare root plants do not mind the lack of media because they get dug, shipped, sold and finally planted into their permanent locations all while naturally dormant through winter. They were in the ground when they went dormant, and will be back in the ground in their new homes by the time they wake up in spring. Because they have not already developed a densely meshed root system within a limited volume of media, they happily disperse new roots directly into the soil where they get planted.

Because they lack relatively bulky cans, bare root plants need less space in nurseries. Many more varieties of deciduous fruit trees, grapevines, roses and berries can therefore be made available. They also cost about half as much as common canned nursery stock.

If bare root plants will not be planted immediately, their roots should be heeled into damp dense mulch (not coarse chips) or soil, and watered. They can be soaked in buckets of water if planting will be delayed only for a day or two. Packaged plants need not be heeled in, and can wait in the shade for more than a week.

Planting holes do not need to be any wider or deeper than the roots. If the soil is loosened too deeply, in will likely settle and cause the new plants to sink. Graft unions must stay above the surface of the soil. (Graft unions are evident where rose plants branch, or as kinks low on tree trunks.) If backfill soil is amended at all, it should be amended only minimally. Otherwise, roots may not want to disperse very far. New plants should be soaked twice in order to settle soil around the roots, but if it rains soon enough, they may not need to be watered again until they start to grow in spring.

Once planted, most bare root plants need some sort of pruning. Fruit trees typically have more stems than they need to maximize the options for their first structure pruning.

Prune

00115
Prune trees get planted bare root.

Does anyone remember when champagne produced in California was formally classified as ‘sparkling wine’? ‘Champagne’ is a technical classification for that which originates from the region of France for which it is named. That makes sense. The technical classifications of prune and plum formerly made sense also, even if not universally understood. Reclassification in 2001 ruined that.

Prune, Prunus domestica, is primarily a European freestone fruit. (The pits of freestone fruits separate from the ripening flesh.) They have firmer flesh than plum, so are more practical for canning and drying. They also have higher sugar content, so might be dried without sulfuring (which prevents molding). Darkly purple and rather oblong fresh prunes are less popular than dried prunes are.

Plum is primarily a Japanese cling fruit. (The pits of cling fruits remain firmly adhered to ripening flesh.) They are softer and juicier than prune, and contain less sugar, so are not as efficiently pitted and dried without sulfuring, or canned. Larger, rounder, more colorful and more richly flavored plums are instead best fresh. They might be bluish purple, purple, red, ruddy orange, yellow or green.

Nowadays, all prunes and plums are known collectively as plums. Dried prunes are just dried plums.

Horridculture – Half-Breed

70726thumbCher explained a long time ago that a half-breed is nothing to brag about. Some of us just don’t get it. A few clients still introduce me to their weirdly bred stone fruit trees as if they are both justification for great pride, as well as something that a professional horticulturist of the Santa Clara Valley has not already encountered a few thousand times. I at least try to act impressed.

The stone fruits that grew in the orchards of the Santa Clara Valley half a century ago were the best. That is why they were grown here. The climate and soil were ideal for their production. Traditional cultivars produced so abundantly and reliably that there was no need to breed new cultivars. The quality was exemplary. Consequently, only a few were actually developed here.

Half-breeds, or weird breeds of any unnatural ratio, started to be developed more than a century ago. A few happened incidentally where different species of the same genus of Prunus grew. They were enjoyed as novelties for home gardens, but were not sufficiently productive or reliable for orchard production. Their fruit was for fresh eating only, since it did not dry or can well.

Now that the orchards are gone, and the only stone fruits in the Santa Clara Valley are in home gardens, these weird half-breeds and others are becoming more popular. Nurseries will soon be stocking several along with their incoming bare root stock. There is certainly nothing wrong with them. However, they are not necessarily any better than their well bred ancestors either.

Apricot, cherry, nectarine, peach, plum and prune, as well as almond, are the traditional stone fruits, of the genus Prunus. (Almonds are the seeds or ‘stones’ of a stone fruit that does not get eaten, but instead gets discarded as a hull.) There are many cultivars of each. Some can be canned. Prunes and some apricots can be dried. There is no need for more, or for ‘improvement’.

Pluot, plumcot, aprium, apriplum, nectaplum, peacotum, pluerry and others like them are the weird interspecific hybrids (which are hybrids of two or more species within the same genus, which for these examples is ‘Prunus‘). Some are half-breeds. Some are breeds of different ratios, such as a half-breed with a half-breed parent, or a half-breed grandparent. It is confusing!

It is also an unjustifiable fad. There are more disadvantages to these weirdly bred stone-fruits than there are advantages. They really don’t get the best of both parents, but might get half of each. Again, there is certainly nothing wrong with that. There are those who legitimately prefer such hybrids. The point is that fads are not necessarily good, and many are just plain weird.

Peach

70726thumbJust like roses and camellias, the innocent peach, Prunus persica, has been developed into too many distinct cultivars to write about in just a few brief paragraphs. It had been in cultivation for thousands of years before arriving in North America. Peach is a classic summer fruit, but trees should be planted while dormant, preferably as bare root stock, about now, in the middle of winter.

Peaches certainly do not grow everywhere in North America. They need just enough chill to be reminded that it is winter; but too much chill too late in the season will ruin bloom. Too much late rain will rot developing fruit. Peaches are therefore right at home in chaparral climates of California, where freestone cultivars are grown for fresh fruit, and clingstone cultivars are grown for canning.

Healthy peach trees can get up to second story eaves, but if properly pruned, should be only half as tall. They should not get too wide either, since the weight of fruit can break limbs. Aggressive winter pruning keeps trees vigorous and resistant to disease. Orchard trees last less than twenty years, although home garden trees are often kept longer. Nectarines are just fuzzless peaches.
