My Garden Diary

November and December 2020

Copyright © 2020 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.

Diary entries for 2004 through 2014

Entries below 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.

Unless a different year is given, dates refer to other entries in the same year as the entry in which they appear, including entries on prior pages for the same year.

Date and Weather Observations and Activities
27 Dec

Mostly clear with some clouds to the east, sunny, and cool

Temp: 49-65
Winter chill: 22.5
Humidity: 28%
Wind: 2-19

Rain —
This rain-year: 0.06
Days since last: 13

A few days ago, raked leaves off the back lawn. There are now mounds of leaves on the main patio and on the paths surrounding the lawn. Yesterday, I raked leaves in front, creating a mound of leaves along the west edge of the driveway.

In anticipation of rain tomorrow, spread gypsum over the larger (east) portion of the front lawn and around the roses to the west of the driveway. This finished the biennial gypsum treatment of my garden. Between the front and back yards, I used about 200 pounds of gypsum. My neighborhood is on a slope, so level house lots are either on fill or cut. Mine is on cut, which means the subsoil — clay — is really bad. Gypsum combines with the clay to make it porous, improving the ability of water and roots to penetrate.

Pruned the 'Black Monukka' grape vine near the bottom of the west side of my My Hill. This year, the vines had very few grapes. Since I saw few immature grapes, I attribute the lack of fruit to pruning the vines too late and not to squirrels or raccoons. Thus, I decided the grape vines would be the first to suffer pruning this winter. Indeed, buds were already starting to break on some of the shoots I removed because of a lack of winter chill.

20 Dec

Clear, sunny, and mild

Temp: 59-80
Winter chill: 22.5
Humidity: 7%
Wind: 1-154

Rain —
This rain-year: 0.06
The past week: 0.01

Filled the green (garden waste) trash bin while raking leaves in front, and did not even get all of the leaves. The back needs to be raked, too.

Bought a Camellia japonica 'Nuncio's Gem' last week to replace the one in the camellia bed in back. The old one was struggling to remain alive. Today, I removed the old one, which had only one leaf, and planted the new one. I still have to get a 'Carter's Sunburst' variety to replace the one that is indeed quite dead.

Spread gypsum on the smaller part of the front lawn, the side west of the brick walk to the front door. I will do the larger part — east of the brick walk — later this week.

6 Dec

Clear, sunny, and mild

Temp: 58-76
Winter chill: 22.5
Humidity: 5%
Wind: 1-12

Days since last: 28

Drought! Aside from a very small amount of rain a month ago, it has been dry. Moisture from that rain was wiped out by very low humidity. Aside from a 3-hour spike to 24% relative yesterday, we have had 10 consecutive days with the relative humidity staying at or below 15%; several days, it did not even reach 10%. And the weather has been unseasonably warm with no winter chill since early last month.

Picked an orange from my dwarf navel orange tree for today's lunch.

The stump left from the Dracaena cutting (10 Nov) now has three buds swelling, which I expect will sprout new shoots.

29 Nov

Clear, sunny, and mild

Temp: 56-77
Winter chill: 22.5
Humidity: 9%
Wind: 2-17

Days since last: 21

Picked up an orange that fell out of my dwarf navel orange tree. It was unblemished, which indicates that it either was knocked loose during a recent wind storm (gusts over 50 miles per hour) or merely fell. It seems the sock with blood meal (4 Oct) is indeed keeping the squirrels away.

Trimmed one of the Podocarpus flanking the brick walk in front. I want these trees to grow as columns, but this one has some wide-spreading branches. I used a pole pruner to cut it back.

The potted California fan palm (Washingtonia filifera) on the brick walk might be dying. Earlier this year, it had as many as six large fronds (leaves). Now it has only two, and one of those is turning yellow. It does have a new leaf shoot, so I will leave it until it is indeed dead.

17 Nov

Clear, sunny, and mild

Temp: 62-80
Winter chill: 22.5
Humidity: 10%
Wind: 1-11

This rain-year: 0.05
Days since last: 10

Raked leaves in front. I raked enought that I almost filled the garden-waste bin for the county's composting program, but none of the trees seem to have lost any leaves yet.

The fruit on my dwarf orange tree is starting to color. I expect to start picking and eating my own oranges in two or three weeks. Every time I count them, I get a different number; but there are approximately a dozen oranges on a tree that is not even 4 feet tall.

Planned to spread more gypsum on the back lawn, but it was too breezy. I would have received a face full of gypsum dust if I tried.

14 Nov

Clear, sunny, and mild

Temp: 48-77
Winter chill: 22.5
Humidity: 27%
Wind: 3-20

Spread gypsum over part of the back lawn, from the west edge almost to The Tree. That included the Artemisia 'Powis Castle' (A. arborescens × absinthium) growing within the edge of the lawn, the fortnight lilies (Dietes iridiodes) between the lawn and main patio, and some of the lilies of the Nile (Agapanthus orientalis) adjacemt to the fortnight lilies. I emptied a full bag of gypsum in the effort. So far, I have applied about 100 pounds of gypsum in back. I will have to buy more to complete the lawn and to apply in front. Generally, I use about 250 pounds of gypsum during this biennial effort.

Fed the artichoke (Cynara scoymus) with a commercial fertilizer that contains a systemtic insecticide. The insecticide has proven harmless to mammals (including humans) and birds. It will prevent spider mites and aphids, which can be serious pests on an artichoke. The artichoke went dormant in the heat of summer and recently resprouted. I was told that feeding in the fall is important for producing edible flower buds in the spring.

10 Nov

Clear, sunny, and cool

Temp: 46-67
Winter chill: 22.5
Humidity: 15%
Wind: 1-15

The past week: 0.05

This time, we got some real rain (28 Oct) but not very much. We also got some winter chill much earlier than in recent years.

The Dracaena cutting (20 Sep) is well rooted. I could tell by the roots starting to poke their way out of the drain holes in the bottom of the plastic pot where I put up the cutting. I moved it to a clay pot and placed it in the greenhouse window in the breakfast room. (I use plastic pots only for rooting cuttings since they tend to keep the rooting medium moist.) The stump left when I took the cutting has not yet sprouted, but it is still green. I will keep it for a while.

Spread gypsum in the rose bed.

3 Nov

Clear, sunny, and warm

Temp: 61-87
Winter chill: 0.0
Humidity: 22%
Wind: 1-12

Rain —
This rain-year: 0.0
Days since last: 169

Divided the 'Gold Galore' bearded iris (I. germanica) in the east bed in back. Actually, the clump did not yet need to be divided. It merely looked crowded because the plants grew quite lush.

Finished applying gypsum to the east bed. First, I had to sift the gypsum because it had formed large lumps in the bag.

Had the back lawn mowed. This is done once each year in the autumn. When The Tree goes dormant, I cannot rake the leaves off the grass unless it has been mowed. If the leaves are not raked, they form a covering thick enough to kill the grass underneath.

Weather data are from the Cheeseboro (CHE) weather station, about 2 miles ENE of my house.

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

Winter chill is the cumulative hours of temperatures at or below 45°F from 1 November through 31 March. It is reported during that period and through April.

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). I also indicate peak wind gusts parenthetically when they are significantly high.

Rain is in inches. Rain-year is the cumulative amount of rainfall from 1 October until 30 September of the following year (our "rain-year"). Week is the cumulative amount of measurable rainfall from noon seven days ago until noon of the indicated date. If no measurable 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. Finally, such characterization reflects when I was actually outside and gardening and ignores changes that occur while I am inside.

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)
