A Second Chance for Tomatoes

A glance at the tomato plant and all looks dried and done for the summer. Temperatures over a hundred in June and July tinged much of Southern California in brown.

But the last week of cool mornings, has given the tomato a second lease on life. 

I was about to take these plants out, but now I'll just trim and pamper. With luck this discovery will lead to late summer tomatoes!

Propagating Epiphyllums

The flower diversity at the Southern California Spring Garden Show prompted Douglas Welch of A Gardener's Notebook and I to talk about plant propagation.

I've successfully grown two variety of epiphyllum for years. The Sunset Western Garden Book gives the common name of "orchid cactus" for epiphyllum. Epiphyllums are a type of cactus with long flat stems that are scalloped along the edges and give the appearance of leaves. The few spines are at the base of these scallops. 

These plants naturally come from the forests of Central and South America where rain is frequent. It is odd to think of forest cactus, but that is what these plants are. They have small shallow roots and typically settle into the nooks and crannies in trees and between rocks. Here in pockets of leaf litter, they thrive on rain water and nutrients washing off the surrounding plants.

The wild plants have large, mostly white-or-cream-colored flowers that bloom at night with a heavy scent. They are pollinated by bats and they produce a fruit that is also eaten by mammals, who then disperse the seeds. Hybridized plants come in a broad spectrum of colors (ESA display at Garden Show) and they tend to flower during the day.

I'm going to share my plants with Douglas. Following the advice of the Epiphyllum Society of America, I cut off a blade and let it heal in a dark dry place for up to 10 days. One of the sections I selected already had a root forming when I cut it.

Douglas can now plant these in a loose soil of bark, sand and potting mix. Let it sit without water for 2 weeks then gradually begin to water occasionally. Once rooted they should be kept moist but not wet. I've found clay pots hold moisture during our hot summer without keeping the plants too wet.  It takes about 2 years for a cutting to bloom.

To get the right amount of air flow, my pots are up on the edge of a wall in partial shade. The second perk to this location is that the sprinklers just lightly reach them.

While epiphyllums are not native to Southern California, the large valley carpenter bee will visit the blooms. Western fence lizards appreciate the elevated location and linger in the pots. And when the blooms open I am reminded how their shape is perfect for hugging a nectar eating bat. 

Finding Inspiration at the Southern California Spring Garden Show

Display by Don Davidson and Fiesta Parade Floats

Last weekend I dashed off to the Southern California Spring Garden Show at the South Coast Plaza with friends. There is something inspiring about the colors and shapes of plants and flowers even when they are showcased indoors.

The colors and textures were dazzling.

notice how the blocks of color are a blend of flowers

The Epiphyllum Society of America illustrated how variation in one plant can make for splendor.

The display gardens were filled with wondrous ideas. "Paint by the Numbers" presented by Living Landscapes (www.LivingLandscapes.us) demonstrated the power of color. (Even though I was looking for some native plants that would also provide habitat.)

"The Art of Exterior" presented by The Garden Gallery highlighted the art of humans and nature. (www.theggallery.com)

While the display garden by the Orange Coast College Horticultural Club & Architecture Technology (www.occhorticultureclub.wordpress.com) integrated natural forms with a complex structure that complimented the organic elements and created airy height.

I've never seen so many different kinds and colors of orchids anywhere in one location. Everywhere you looked there were inspirational shapes, colors, textures, combinations and the simple reminder that nature is rejuvenating.

Visit a local garden show, go for a walk in a local park or nature center. Take in the tonic of spring.

For more inspiration visit my friend Douglas Welch's blog A Gardner's Notebook for video and photos of the Southern California Spring Garden Show. Toward the end of the video, I promise there is a purple orchid like nothing you have ever seen.

Giant Mosquitoes ?

There’s been concern among some of my neighbors that we are being invaded by giant mosquitoes.

Actually, the spring rains have encouraged the pupation of large numbers of common crane flies (Tipula planicornis). At first glance, these long-legged flies do look like mosquitoes, but they actually have very little in common.

The crane fly larva feeds on roots and plant matter under leaf litter. It kind of looks like a large (half inch long) thick-skinned maggot. It isn’t an attractive childhood, but it is nothing like the aquatic mosquito. Once the crane fly develops into an adult with wings it has a fairly short lifespan and typically does not eat. You can tell it is a fly and not a mosquito because it only has two wings (one pair). Mosquitoes and all other kinds of flying insects typically have four wings (two pairs).

Some people call crane flies “mosquito hawks” with the assumption that they eat mosquitoes. Unfortunately, that is a myth. Personally, I think they look like fairies when they fly up from the grass.

The past year’s warm dry weather followed by a moderate winter with normal rainfall has enhanced grass growth. Crane fly larva prosper in grass and we seem to be having an unusually large population of adults this spring. The females are considerably thicker in body. One source said that females are unable to fly. There appear to be far more males than females, and I saw a group of males mobbing a single female all trying to mate with her.

Is anything eating these crane flies? So far I haven’t seen any birds or other animals munching on the flying adults. If you look at them closely, they are mostly long brittle legs and glassy wings. There isn’t much to eat. However, I’m sure that as larva they are consumed by a number of our yard birds, Bewick’s wren, California and spotted towhee. Perhaps their availability added to the Bewick's decision to nest in our yard. Bewick's wren nest.

So don’t be alarmed by a large long-legged crane fly headed your direction. It isn’t a mosquito and it isn’t going to hurt you. Part of being a good gardener is getting to know the species in your yard. The common crane fly isn’t going to harm you or your garden. In fact I noticed a young alligator lizard sunning itself about a foot from the breeding crane fly group. Maybe it was waiting for the soon to be laid, crane fly eggs.

Native Plants Beat the Freeze

Cold weather has destroyed citrus and other agricultural crops across California. Frost damaged plants can be seen in most residential yards. But if you look past the destruction, there is something important to note: the native plants are fine.

When I began to investigate the damage in our yard, I was struck by the resilience of the native plants. Not only had they survived the frosty cold, but some, like the white flowering currant (Ribes indecorum), were blooming and happy.

In this photo you can see the cascading white currant flowers, while the blackened foliage at the bottom of the picture is one of many frost damaged spider plants (Chlorophytum).

On January 13, 2007, Los Angeles recorded its lowest winter temperature. In Woodland Hills, we had several nights between 26 - 30˚F. On the morning of the 13th there was a quarter inch layer of ice across our bird bath. I removed the layer of ice and put it on the ground. Throughout the day, the ice never melted; unheard of in sunny California.

Not only was the disk of ice still on the ground the next morning, the water in the two-inch-deep bird bath was frozen solid. The band-tailed pigeons were walking on their own ice rink, quite mystified.
















Throughout the yard, even in protected areas, exotic species, like the Mexican agave (Agave attenuata), were drooping with frost damage. While only two feet away, the newly planted native Channel Island tree poppy (Dendromecon harfordii) was unscathed.












On the exposed hillside, the California holly or toyon (Heteromeles arbutifolia) thrived, unconcerned with the bitter temperatures.

Even in the more protected front of the house, it was quite obvious that the brilliant green foliage of the “Yankee point” California lilac (Ceanothus gloriosus horizontalis) was unharmed by the frost while the African daisy (Osteospermum fruticosum) turned yellow and wilted.

If creating habitat around your home for native animals isn’t enough of a reason to change your landscaping over to natives, consider the changing weather. Native plants are not only more adapted to the dry hot California summers and require less water, they also are more resilient to freezing cold.

Be water wise, habitat wise and climate wise, plant natives.
