My Garden Diary

November and December 2011

Copyright © 2011 by David E. Ross

Many years ago, when I first started my Web site, I created an online diary of my gardening activities and observations. However, with work and the commute from Hell, I was often so tired I had to choose between maintaining my garden and maintaining my diary. Sometimes, I did neither. In 1998, I stopped my diary and removed the pages from my Web site.

Now I am retired. I am well-rested and have plenty of time to both garden and maintain a diary. This diary is primarily for my own benefit, so that I can look back upon what I did and when. But I thought others might also be interested, so here it is.

Entries are in reverse order (latest at the top). Daily, I might stoop to pull a weed or use a hose to water some potted plants; however, I don't consider those significant gardening activities. Thus, you will not see daily entries. Also, I might accumulate a few entries before updating this page on the Web.

When plants have well-known common names, their scientific names are given only the first time they appear on this page (entry closest to the bottom). There, the common name is in bold or appears as a link to another Web page.

Dates refer to other entries in the same year as the entry in which they appear unless a different year is given. However, they may refer to entries on prior pages.

Date and Weather Observations and Activities
29 December

Clear, sunny, and mild

Temp: 64-80
Humidity: 51%
Wind: 0-17

Rain —
Season: 2.85
Days since last: 12

Raked even more leaves in back. There are mounds of leaves on my patio and the paths through the back yard. I didn't even bother to rake in front since I have no place to put the leaves.

Pruned another rose in back. Soon, I'll have to start pruning roses that are still blooming.

Pruned the two grape vines at the bottom of My Hill — the 'Perlette' and 'Black Monukka'. The 'Flame' grape at the top of My Hill will have to wait until I am exceedingly ambitious.

24 December

Clear, sunny, and cool

Temp: 57-69
Humidity: 3%
Wind: 8-25 (gusts to 43)

Rain —
Season: 2.85
Week: 0.46

The Aloe vera cuttings (14 Sep & 27 Oct) finally developed sufficient roots to pot them. I discarded the parent plant and made fresh potting mix. The mix is quite lean on peat moss and nutrients, which is appropriate for most succulents.

One of the Shasta daisy cuttings (14 Dec) is quite dead. On the other hand, the 'Simply Marvelous' rose cuttings (11 Dec) are sprouting leaves. Of course, it's too soon for those woody cuttings to have roots.

Filled the green trash bin with leaves from the front of the house and the side walkway. I need to rake the back lawn, but the wind was blowing too strong to leave piles of leaves on the ground.

Pruned two of the seven roses in back. Four other roses there are still blooming. The seventh is the climbing 'Peace', which is so large that it will be a task by itself.

I don't know what has been blowing on the wind. As I compose this, I am having my worst hay fever attack in years; and my wife has had four asthma attacks in the past 24 hours.

22 December

Clear, sunny, and cold

Temp: 44-54
Humidity: 7%
Wind: 7-36 (gusts to 57)

Rain —
Season: 2.85
Week: 0.06

I need to rake leaves again, in both the front and back; but the wind is too strong.

Pruned three of the six roses in front. The other three are still blooming.

14 December

Clear, sunny, and cool

Temp: 44-59
Humidity: 58%
Wind: 0-17

Rain —
Season: 2.79
Week: 0.60

Yesterday, I received a phone call from the person at the National Park Service who is responsible for the Cheeseboro (CHE) weather station (8 Dec). He explained how he maintains the station. He indicated that differences in minimum temperatures that I've seen between CHE and another local weather station could be the result of how cold air drains down a slope. CHE is on a ridge, and cold air drains away. The other station is near the bottom of a slope where cold air can accumulate. I'll continue to rely on CHE for weather and climate data.

Raked leaves, both in front and back. In back, I only did half the lawn; tomorrow, I plan to finish the lawn. The green trash bin for the county's composting program is almost full, so I'll likely have to pile leaves on the paths and patio.

The Shasta daisy cuttings (8 Dec) do not seem to be surviving. I think I took them at the wrong time of the year. Perennial cuttings generally do much better when taken in the spring.

11 December

Cloudy, mostly grey with some hazy sun, cold

Temp: 43-58
Humidity: 60%
Wind: 0-10

Rain —
Season: 2.19
Days since last: 21

Yesterday, with permission from the manager, I took four cuttings from 'Simply Marvelous' florabunda roses at the gardens where I'm a docent. Today, I potted them in an attempt to root them.

Broadcast generous amounts of gypsum over the smaller portion of my front yard (8 Dec), the teardrop bed in back, around the gardenia (G. jasminoides 'Veitchii'), and around each individual Camellia sasanqua in the east and rose beds. I also broadcast some soil sulfur in the camellia and teardrop beds and around the gardenia and C. sasanqua. This completes all the soil treatments that I am planning for this winter.

Lightly trimmed the Australian tea tree (Leptospermum laevigatum). I generally avoid any pruning of my broadleaf evergreens at this time of the year because cutting promotes new growth that will be damaged by our night-time frosts. However, a few branches on the tea tree were interfering with the paths around the teardrop bed.

8 December

Clear, sunny, and cool

Temp: 50-69
Humidity: 12%
Wind: 0-10

Rain —
Season: 2.19
Days since last: 18

The temperature range shown to the left is suspect. Another weather station in the area indicates a range of 39°F-70°F.

Potted the Shasta daisy cuttings (10 Nov). I already have plans for what cuttings I will attempt to root next.

Broadcast gypsum over the main part of the front lawn and in the camellia bed in back. As it dissolves and leaches through the soil, the gypsum (calcium sulfate) reacts with the clay in the soil to make it granular and porous. This improves drainage, the ability of roots to spread, and the movement of nutrients. I will treat other areas soon; but I won't be as thorough as last year, when I used over 150 pounds of gypsum.

Raked more leaves in front.

Had my favorite tree service come to prepare an estimate for trimming my five largest trees. I can't get onto the schedule for the work earlier than this coming February.

4 December

Clear, sunny, and cool

Temp: 46-64
Humidity: 9%
Wind: 1-20

Rain —
Season: 2.19
Days since last: 14

Fixed the drip irrigation for the roses in front (19 Nov). I then filled in the hole where the rose bush had been removed so that no one would be injured by stepping into it. I topped the fill with a generous amount of gypsum so that the hole can be readily dug when I get a new rose.

Spread a mixture of gypsum and soil sulfur around the liquidambar tree (L. styraciflua). This will help prevent chlorosis next year.

This past Thursday, my wife looked out our bedroom window and saw the gardener next-door using a leaf blower (an abomination that should be made illegal) blowing leaves from our neighbor's front lawn onto our driveway. I confronted him and told him to clear up his mess from my property. He claimed the leaves were all from my oak tree (Quercus lobata) and he was merely returning them. However, the mess included leaves from the street tree in front of the neighbor's house. The gardener raked up most of the mess and removed it. The house is a rental, and the gardener is employed by the landlord and not the tenant. I talked to the tenant, and she will convey my complaint to her landlord. She indicated that the gardener's performance in other ways has been quite unsatisfactory.

The recent Santa Ana winds piled leaves of all kinds into drifts, just as winter winds elsewhere create snow drifts. The Tree has not yet started to lose its leaves; otherwise the drifts could have been waist-high. I again filled the green trash bin with leaves.

Fortunately, the winds here were not as severe as elsewhere in southern California. Locally, I saw no trees uprooted, power lines downed, or buildings damaged. The winds here were not as bad as in January 2003.

24 November

Cloudy, mostly grey with occasional hazy sun, cold

Temp: 47-58
Humidity: 65%
Wind: 1-7

Rain —
Season: 2.19
Week: 0.56

Stirred the grass clippings from last Saturday (19 Nov) into my compost pile. The clippings were already getting quite warm, indicating that composting had already begun.

Yesterday, raked leaves in front into three large piles. Today, I packed as much as I could into the barrel that had been used for grass clippings. The rest of the leaves went into the green trash bin for the county's composting program.

I need to visit the local garden plumbing store to fix the drip irrigation that was damaged when the dead rose stump was removed from the front rose bed.

So far, we are slightly ahead of last year in terms of rainfall but definitely behind last year in terms of winter chill.

19 November

Partially cloudy, intermittent sun, and cool

Temp: 49-63
Humidity: 58%
Wind: 0-10

Rain —
Season: 1.63
Days since last: 7

The gardener came this morning and did all the work I requested (17 Nov). Per my request, he left me a half a barrel of grass clippings to add to my compost pile. While removing the rose bush stump, however, a line for the drip irrigation system for the roses was broken. I can fix that quite easily.

Those easterners who deride us in southern California for having no fall color obviously do not know where to look for color. While we do not have masses of the same tree in this urban area, individual trees are striking with pale yellow (birch), bright yellow (ginkgo and Modesto ash), flame (crepe myrtle), and multicolored confetti (liquidambar), just to identify a few. This past week, I took a photo camera icon of my Japanese zelkova (Z. serrata) at the peak of its fiery display. Sometimes, I think those easterners are merely jealous, resenting our mild, snowless winters.

17 November

Clear, sunny, and mild

Temp: 59-77
Humidity: 28%
Wind: 0-18

Rain —
Season: 1.63
Week: 0.51

Swept three buckets full of seeds from The Tree off the patio.

Arranged to have the red fescue (Festuca rubra) lawn in back mowed this coming Saturday, generally a once-a-year event. The gardener will also remove the rose bush stump (22 Sep) in front.

10 November

Cloudy, grey, and mild

Temp: 58-70
Humidity: 12%
Wind: 3-13

Rain —
Season: 1.12
Week: 0.66

The Shasta daisy cuttings (27 Sept) have started developing roots. I'll leave them alone for another few weeks to allow more substantial root balls to develop. I put two cuttings in each of two pots. Interestingly, one cutting is each pot died; and one is developing roots.

Broadcast gypsum in front adjacent to the house, where long-established shrubs are struggling because the soil has become too compacted.

Started to rake leaves again (30 Oct), but a very annoying fly kept dive-bombing my ears. I finally quit and went inside.

Weather data are from the Cheeseboro (CHE) weather station, about 2 miles ENE of my house (reported in prior diary pages as 1.2 miles).

The high temperature (°F) is daytime for the indicated date; the low temperature (°F) is for the night ending on that date.

The relative humidity is at noon. (In my garden, it is likely higher than reported, a result of regular irrigation.)

Wind speeds (mph) are average (not peak) low and high, midnight to midnight (subject to later correction for diary entries posted before the end of the day).

Rain is in inches. Rain amounts are omitted after 60 consecutive days elapse without any measurable amount. Season is the cumulative amount of rainfall since the start of the current rainy season, which began on 5 Oct 2011 with the first measurable rain in 120 days, until noon on the indicated date. Week is the cumulative amount of rainfall from noon seven days ago until noon of the indicated date. If no rain fell in that period, Days since last is reported.

Characterization of the weather (e.g., Clear, sunny, and warm) is purely subjective; for example, "warm" might occur with higher temperatures than "hot" if the former occurs with lower humidity and more breezes than the latter. Also, a day that would normally be characterized as "mild" might instead be "warm" if the immediately previous days were quite cold.

The signature line I use when writing messages about my garden includes the following:

Climate: California Mediterranean
Sunset Zone: 21 -- interior Santa Monica Mountains with some ocean influence (USDA 10a, very close to Sunset Zone 19)
