KPCR Garden Report Update

Now, it is a bit more official. I have an appointment at 11:00 tomorrow morning, Tuesday, January 13, for the first episode of the KPCR Garden Report. I do not yet know if it will merely be recorded for later broadcast, or if it will be broadcast directly, but I suspect that it will be broadcast directly. More information about the KPCR Garden Report is cited by the recycled article below:

November 5, 2025 – Nothing is official yet. I am hopeful, though. I am currently in training to establish a new Garden Report on Pirate Cat Radio KPCR-LP 92.9 FM in Los Gatos, KMRT-LP 101.9 FM in Santa Cruz, KVBE-LP 91.1 in Portland, and online at KPCR.org. For me, it is daunting. However, those training me are confident of my ability. I have no problem talking about horticulture for an hour. My difficulty is operating the necessary electronics. It is not much, and actually looks quite simple. I am just not comfortable with it. I am intent on doing what I must, though. I miss my former Garden Report gardening shows on KSCO 1080 AM in Santa Cruz and KBCZ 89.3 FM in Boulder Creek. Ultimately, I would like to post recordings of the new Garden Report here on the blog, or at least post links to such recordings. I am told that is not difficult to do, if I record the shows, which is apparently standard procedure. I still need to find “intro” music for the beginning and end of each show, but I believe that I have a source for that. Goodness, although I know this should be easy, I am nervous!

Dormant Pruning For Fruit Trees

Dormant pruning is severe but specialized.

Bare root season begins now because bare root stock is so efficiently dormant for winter. Dormancy is the same reason that this is now also time for dormant pruning of fruit trees. It is comparable to anesthesia for surgery. Affected fruit trees waken from dormancy after winter with no idea of what happened. They then resume growth as if nothing happened.

Dormant pruning is important because of the unnatural breeding of most fruit trees. They have been bred to produce unnaturally large and unnaturally abundant fruit. Their fruit is so excessive that they can not support all that they could produce. Dormant pruning both limits production and concentrates resources. Resulting fruit is less abundant but bigger.

Bigger, better but less abundant fruits collectively weigh less than overly abundant fruits. Furthermore, dormant pruning improves structural integrity of affected trees. So, affected trees are able to support more weight but must support less. Ideally, they should need no propping for limbs that are too heavy with fruit. Limbs should not break from their weight.

Dormant pruning also directs and stimulates growth. It should prevent stems from getting so high that their fruit is beyond reach. Actually, most fruit should be within reach from the ground without a ladder. Vigorous growth is more resistant to pathogens than congested and less vigorous growth. There are actually quite a few advantages of dormant pruning.

Stone fruit trees and pome fruit trees are popular types that need dormant pruning. Stone fruit include apricot, cherry, nectarine, peach, plum and prune. They need similar pruning but to varying degrees. Peach needs more severe pruning because its fruit is so big and heavy. Cherry needs less aggressive pruning. Apple, pear and quince are all pome fruit.

Deciduous fruit trees are quite demanding, and reliant on timely dormant pruning. Those who would like to grow them should first be aware of their cultural requirements. Diligent research of pruning technique is helpful. Practical and annual experience is even better. Each year, it is an opportunity to observe how subject trees respond to dormant pruning.

Six on Saturday: Silly Succulents

Five of these six succulents have weirdly silly common names. I did not notice until after I got all of their pictures.

1. Carpobrotus edulis or Carpobrotus chilensis, pigface is a new acquisition that should help stabilize a sandy bank in one of our landscapes. It came from a beach in Santa Cruz.

2. Aeonium arboreum, common houseleek not only has a silly name, but also has a silly form, with wide foliar rosettes suspended by lanky and otherwise awkwardly bare stems.

3. Graptopetalum pentandrum, bluebean is not actually within any of the landscapes. It is a diminutive specimen that remains potted in the nursery. I am unsure of its identity.

4. Echeveria elegans, Mexican snowball contrasts splendidly with the limey green of the common houseleek, which it grows at the base of. I would not mind more of these about.

5. Crassula ovata ‘Hobbit’, Hobbit’s pipe, like common houseleek, is silly both in name, and in form, with these oddly tubular leaves. It is a lighter green than typical jade plant.

6. Crassula ovata, jade plant is the only one of these Six that lacks silliness. Its bloom is too cute in closeup view to omit, though. Besides, Six on Saturday is better with flowers.

Forsythia

Forsythia blooms very early in spring.

This may seem to be unseasonable for now. Forsythia, Forsythia X intermedia, does not bloom until early spring. However, this is the time to plant it as bare root stock. It is one of only a few fruitless ornamental species that is available as such. New specimens will not bloom much for spring. They grow through summer, though, to bloom for the next spring.

The famously bright yellow flowers of forsythia are small but very abundant. They bloom on bare stems before their deciduous foliage regenerates. The simple paired leaves are about two or three inches long. Mature specimens mostly do not grow more than ten feet tall unless partly shaded. Most branches arch upward and outward from their root bases.

Pruning should involve the removal of deteriorating older canes, to favor younger canes. Complete removal at their base promotes more vigorous new basal growth. Pruning can happen after bloom rather than before. Pruning of the exterior compromises the naturally outwardly flaring form. Complete coppicing eliminates all bloom for the following season.

Bare Root Season Begins Now

Bare root stock is less expensive.

Wintry weather, although unpleasant at times, has certain advantages. Most importantly, it provides rain here, and snow in the mountains for water reserves. Gardening would be very different with any less. Also, cool weather initiates dormancy for most plant species, giving them a time for rest prior to spring. This is what makes bare root season possible.

Bare root stock is exactly what it sounds like. It is available for sale without the soil that it grew in. Some comes with an individual bag of moist sawdust around its otherwise bare roots. Most merely rests with its otherwise exposed roots in damp sand at nurseries until purchase. Because it is so portable, much is available by mail order, or online purchase.

Bare root stock becomes available now because this is when it is dormant. It comes into nurseries as readily as Christmas trees relinquish their space. Because it is dormant, it is unaware of what is happening to it. Dormancy works like an anesthetic for major surgery. Ideally, bare root stock awakens in its new gardens without any idea how it arrived there.

There are several advantages to bare root stock. It is much less expensive than canned, or potted, nursery stock. It is less cumbersome to bring home from nurseries. Because its roots were never confined, they disperse readily into surrounding soil. For some types of plants, more varieties are available bare root. Several plants are only available as such.

Roses and fruit trees are the most popular of bare root plants. More cultivars of roses are available now than at any other time of year. Fruit trees include primarily stone fruits and pome fruits. Stone fruits include apricot, cherry, plum, prune, nectarine and peach as well as almond. Pome fruits include apple, pear, crabapple and Asian pear as well as quince.

Cane berries, including blackberry and raspberry, are also available with bare root stock. So are perennial fruit and vegetables like strawberry, rhubarb, artichoke and asparagus. A few deciduous but fruitless shrubs, trees, vines or perennials are sometimes available. These might include lilac, forsythia, clematis, wisteria, astilbe and deciduous magnolias. Grapevines and nut trees are also available.

Six on Saturday: First Six of 2026

Even if there were plenty of flowers to take pictures of, I have not been in the landscapes much while it is so rainy. These are from the nursery.

1. Opuntia ficus-indica, prickly pear pads were found at the dump while other landscape debris was being dumped. I was not involved. However, I will be pleased to install them.

2. Buxus japonica, Japanese boxwood turns so yellowish during winter, that it seems to have died this year. We have been trying to find a use for this specimen for quite a while.

3. Canna indica ‘Alaska’ canna is obviously not ‘Alaska’, which has simple green foliage. I suspect that this is ‘Tropicana’. I hope that its spotty foliar discolorations are not virus.

4. Canna indica ‘Australia’ canna got plucked where it migrated a bit too far. These pups will be canned and grown for other landscapes. Surplus might be shared with neighbors.

5. Sarcococca ruscifolia, sweet box produces black berries. Apparently, such berries are red before they ripen to black. I was not aware. There are typically not enough to notice.

6. Sarcococca ruscifolia, sweet box berries are unfortunately poisonous. Otherwise, they look like they might have culinary application. They are unusually abundant this season.

Laurustinus

Laurustinus can become a small tree.

Winter bloom may or may not be an benefit of laurustinus, Viburnum tinus. Most grow as regularly shorn hedges that are unable to bloom much between shearing. Those that do bloom often generate a floral fragrance that some find to be objectionable. Nonetheless, with only timely pruning, laurustinus does bloom for winter. Many consider this an asset.

Flowers are small and white or blushed with pink. They huddle together in dense cymes, which are about two or three inches wide. Their dense evergreen foliage is forest green. Individual leaves are paired, about two or three inches long, and half as wide. They have a very slightly raspy surface texture. Mature laurustinus can sucker from their basal roots.

If bloom is not a concern, laurustinus can be a dense shorn hedge, only several feet tall. Otherwise, it can become a dense small tree more than twenty feet tall and ten feet wide. Once established, it does not need much water and can actually survive with just rainfall. It is not very discriminating about soil quality. Mites or mildew can become problematic in damp coastal climates, particularly among shaded or very congested specimens.

Winter Flowers May Be Scarce

Not many flowers bloom for winter.

Evergreen foliage and berries are now popular for home decor for a primary reason. Not many winter flowers are blooming and available for cutting and bringing in. Most flowers prefer to bloom while more pollinators are more active. Not many pollinators are out and about while weather is cool through winter. Consequently, winter flowers may be scarce.

However, they are not actually as scarce as they seem to be. Some winter flowers bloom without drawing attention to themselves. They do not need to if they rely on wind for their pollination. Colorful flowers are colorful only to attract pollinators. For example, redwood is blooming quite privately about now. It produces no prominently colorful flowers to see.

Some winter flowers do not actually intend to bloom in winter. They are merely confused by the local climates. For example, African daisy blooms whenever the weather is warm. It does not know to stop blooming for winter here because the weather is not overly cold. Cala are tropicals, so have no concept of winter. They should not bloom, but might try to.

Camellias are some of the most familiar and popular winter flowers. Sasanqua camellias bloom before common camellias. Different cultivars of each type bloom at different times. The latest sasanqua camellias might actually bloom after the earliest common camellias. Sasanqua camellias bloom more abundantly. Common camellias provide larger flowers.

Although most salvia bloom during warmer weather, a few bloom sporadically for winter. Autumn sage seems to never be completely without bloom. Meanwhile, cultivars of witch hazel bloom curiously on bare stems. So does winter jasmine, but only in yellow. Oregon grape can bloom impressively within cooler climates. It is evergreen and blooms yellow.

Many of the better winter flowers are cool season annuals, which are no good for cutting. These comprise pansy, viola, cyclamen, dianthus, snapdragon, nemesia and primroses. Stock is exceptional, because it can be cut and brought inside and is splendidly fragrant. Ornamental kale and ornamental cabbage are foliar plants that present like wide flowers.
