There are a few consequences to all this excellent rain. Gutters are flooding. Trees are falling. Mud is sliding. As much as we should be grateful for what we are getting while we are getting it, it is getting rather old. Clear and sunny weather that is forecast after today will be a welcome relief from all this muddy sogginess.
Almost all of the flowering cherries have somehow postponed bloom. It has not been unusually cold. It is as if the trees somehow know better than to bloom while so much unusually heavy rain is falling. Otherwise, they might have bloomed only briefly before the blossoms got knocked off. The buds are so fat that I expect they will begin to bloom by the middle of the week. Only one flowering cherry that always blooms significantly earlier than the others bloomed on time, and is already finished. Considering how heavy…
There are thousands of them, these weird motionless caterpillar like ‘things’, in big herds under all the cottonwood trees. They make a squishy mess in the rain, and stain concrete. They may not look like much from a distance, and are merely ignored as a minor nuisance that must be swept from pavement, but on closer inspection, they really look unworldly, like something from another planet, or a bad Japanese science fiction movie. They are just male catkins of the native cottonwoods. At least I believe they are. If there are female flowers mixed in, I would not know it. Nor would I know if they really are from another planet. I know that the cottonwoods will later make quite a mess with their cottony fluff that carries their seed away on the wind, so they must do what it takes to generate seed, which generally involves flowers of both…
Esperanza and poinciana seed sent to me by Crazy Green Thumbs at the end of last year were finally sown! Actually, they were sown two weeks ago, but I somehow deleted their pictures before sharing them here. Consequently, there is not much to see now. After the failure with the esperanza seed that The Shrub Queen sent to me previously, I am intent on growing these properly. Esperanza is more popularly known as yellow bells, and may alternatively be known as yellow elder, yellow trumpetbush or Ginger Thomas. I have no idea who Ginger Thomas is, or why she is relevant. Poinciana is more correctly known as pride of Barbados, and may alternatively be known as Mexican bird of Paradise, red bird of Paradise, peacock flower, dwarf poinciana, flos pavonis, flamboyant de jardin or ‘ohai ali’i. I know it as poinciana only because I have never encountered real poinciana here.
1. Tecoma stans and Caesalpinia pulcherrima seed were sent from Texas during the last few days of last year by Crazy Green Thumbs. I finally put them out only two weeks ago.
2. Tecoma stans seed are not much to look at while under a thin layer of damp media. Of course, they look totally awesome to me. There were too many seed for separate cells.
3. Caesalpinia pulcherrima seed are about as fascinating after getting sown. Since there are not as many seed, they got separate cells, which are almost discernible in the picture.
4. Darla the kitty has mistaken seeded flats for litter boxes in the past. Boundless forests are apparently inadequate. Upside down flats should protect the freshly sown seed flats.
6. Darla hates me. I can not get close enough to get a good picture of her. This picture is zoomed in from a safe distance. She needs to keep her distance from the seeded flats.
Variegated Coprosma X kirkii has very glossy light green leaves with white margins that look great cascading over retaining walls.
Coprosmas are so innately undemanding and complaisant to all sorts of conditions, that some types self sow and thrive untended in riparian or coastal environments. If they were more aggressive, they would likely naturalize (proliferate as if native) where the soil does not get too dry through summer. With such glossy foliage that looks like plastic, they might be appealing weeds.
Coprosma X kirkii is a resilient ground cover that mostly stays less than two feet deep and five feet wide, although overgrown plants can get three feet deep. Varieties with colorful or variegated foliage probably stay too small to be reliable ground cover over large areas, but make nice edging, or can cascade nicely from raised planters or urns.
Most euonymus are upright shrubbery. This one though, stays low enough to be useful as a shallow shrubby ground cover.
Of all the functions that the many and various plants in the garden serve, ground covers have the lowliest job description. Well, maybe it is just the lowest job; covering the ground. It is an important job though. Ground covers fill in the space between other desirable plants to obscure otherwise bare soil. They also control weeds. Some ground covers help to limit erosion. Others help to insulate the soil for plants with sensitive roots.
There certainly are all sorts of ground cover. Lawns are the most familiar. Many other ground covers are perennials like gazanias, African daisies and iceplants. Some, like ivies, honeysuckles and star jasmine, are vines. Others are low growing shrubs like certain coprosmas, cotoneasters and junipers. Some lay about as flat as carpeting. Some get a few feet deep.
Many perennial ground covers as well as some of the vines and low growing shrubbery provide colorful flowers. Japanese honeysuckle and star jasmine are not as colorful, but provide delightful fragrance. Some of the cotoneasters have colorful berries in winter. Although not seen, many ground covers are appreciated more for their network or roots that help to stabilize soil that might otherwise erode. One feature that most ground cover plants have in common though, is their foliage that is dense enough to keep weeds out, as well as to obscure the soil below.
Like all other plants in the landscape, ground cover plants need maintenance. Lawns probably need more maintenance than any other ground cover, since they need to be mowed, weeded, fertilized and watered quite regularly. Vine ground covers need to be pruned so that they do not get into trees and shrubbery. Some ground covers look best if mowed annually (typically at the end of winter) or even more frequently. Some of the deeper ground cover shrubs should be pruned down to stay low. Almost all ground covers need to be edged for confinement.
Ground cover plants must be selected for their appropriateness to particular applications. For example, most low growing shrubbery needs space, so is best for larger areas. Smaller iceplants that may not be aggressive enough for big areas are great for tight spots, or for mixing with other perennials. Tough Algerian ivy that is so useful for freeway embankments may be too aggressive for home gardens. As with all plants in the garden, careful selection helps to get the best ground cover plants for each particular situation where ground covers are needed.
English ivy, Hedera helix, is probably the nastiest and most aggressively invasive exotic species that I work with. It climbs high into redwood trees and overwhelms understory plants (that live below the trees). It invades many of the landscapes, and worst of all, it climbs building where it ruins paint and causes rot. It grows faster than we can keep up with it.
English ivy is actually a nice ground cover plant for refined landscapes. I grew it at my home in town. Contrary to popular belief, it does not root into and parasitize the trees that it climbs. Actually, it rarely overwhelms and shades out large trees. It prefers to keep them alive for support, from which it disperses its seed. However, it does promote decay in the trunks that it climbs, particularly where it retains moisture at ground level. Native trees are not accustomed to that.
Like most warm season vegetables, tomatoes, Solanum lycopersicum, are actually seed bearing fruit. They are both the most diverse and the most popular home grown produce. Grape tomatoes are smaller than little grapes. ‘Beefsteak’ can get wider than five inches. Although mostly red, some are yellow, orange, pink, green, brown, purple or pallid white.
The most popular varieties of tomato for home gardens are indeterminate. They produce fruit sporadically throughout the season, on irregularly sprawling stems. Tomato cages or stakes support their growth. Shrubbier determinate varieties seem to be more productive only because all of their fruit develops within a brief season. They work well for canning.
Small tomato plants in cell packs and four inch pots, which are available from nurseries, should grow efficiently in the garden as the weather warms through spring. Varieties that are unavailable as small plants can grow from seed in cold frames through late winter, to be ready for the garden after last frost. Directly sown seed can be vulnerable to mollusks.
Warm season annuals for next spring and summer are already replacing the cool season annuals that bloomed so dutifully since last autumn. As this happens, it is also getting to be about time for warm season vegetables to replace cool season vegetables. Strangely continuous warm daytime weather since December accelerated this process somewhat.
Removal of cool season vegetables that are still productive is as unpleasant as removal of cool season annuals that are still blooming. Fortunately, most cool season vegetables are finished by now, or will be soon. Few linger into warm weather as some cool season annuals might. Regardless, warm season vegetables will need their garden space soon.
Unlike most cool season vegetables, which actually are vegetative, the majority of warm season vegetables are actually fruits. The plants that produce them generally continue to bloom and produce more fruits throughout their respective seasons. Some, such as bush bean and determinate tomato, exhibit brief seasons. Many produce continually until frost.
Therefore, indeterminate tomato, pole bean, squash, cucumber, many varieties of pepper and some varieties of eggplant need no replacement within the same season. Cucumber can get tired enough by early summer to justify replacement in midsummer though. Okra, as well as several varieties of eggplant and pepper, produce for relatively brief seasons.
Phasing prolongs production of warm season vegetables that produce only once or only for a brief season. For example, corn that matures so uniformly that it is ready for harvest simultaneously lasts only a few weeks in a garden. Phases for seeding that repeat every two weeks or so develop in two week cycles. As the first phase finishes, the next begins.
Because so many individual plants are desired, and the seedlings do not transplant well, corn seed prefers direct sowing into the garden. So does seed for bean, root vegetables, and most greens. For tomato, pepper and eggplant, and perhaps cucumber and squash, small plants transplant well, and are not numerous enough in a garden to be expensive. Warm season vegetables grow slowly during cool weather, but accelerate as the weather warms.
What makes this Bullwinkle worse than most is that I pruned it like this myself. What makes it worse than worse is that it did not need to be pruned in this disfiguring manner for clearance from utility cables like the last one I wrote about was. https://tonytomeo.com/2018/08/08/horridculture-bullwinkle/ It is instead an attempt to renovate an overgrown hedge that was behaving something like a fat hedge. https://tonytomeo.com/2018/06/06/horridculture-fat-hedges/
In fact, the only reason it did not qualify as a fat hedge is that it had plenty of space for all of its superfluous bulk The side to the left was only beginning to encroach into the driveway on that side, and was easily pruned back to the curb, which for now, is adequate confinement. The side on the right was only beginning to encroach into the upstairs balconies, and was likewise easily pruned back for reasonable clearance.
It is gratifying to see that, on rare occasion, it actually rains here. This year, the weather has been dry for a bit too long. Dry weather is normal, but concerning.
Supposedly, all this rain has not been too terribly excessive. It seems to have been raining more frequently than it normally does, with only a few days without rain in between, and more often, many consecutive days of rain. The rain also seems to be heavier than it normally is. Yet, the total rainfall is not too much more than what is average for this time of year, and well within a normal range.
The volleyball court at Felton Covered Bridge Park looks more like a water polo court at the moment. The pair of ducks out of focus on the far side seem to dig it. The water is not as turbulent at it is the San Lorenzo River where they live. Speaking of the San Lorenzo River, it has been flowing very well and at a relatively continuous rate. It came up high only for a short while…
