La Nina 2010 in the Santa Cruz Mountains

Mother Nature sure knows how to throw a curve ball. She can dish out balmy 75 degree weather one day, then switch it up to 107 in a heart beat.  Cold and windy comes to the mound next followed by "what’s next?"  from the pinch hitter.  I hear rumblings about a strong La Nina coming to town this winter.  What will this mean to us here in the Santa Cruz mountains? Will it be a dry winter?

To understand major climate trends, scientists collect temperature readings every week from dozens of buoys in the Pacific Ocean. They combine them with satellite images and temperature readings from ships, then plug the data into computer models from scientific agencies around the world.

According to Klaus Wolter of NOAA’s Earth System’s Research Laboratory, water along the equator in the Pacific is currently between  2 – 3.8 degrees Fahrenheit cooler than normal. In extreme La Nina events, it can get up to 7 degrees F cooler.

While a La Nina often allows the Pacific jet stream to trend further northward, bringing increases precipitation to the Pacific Northwest and below normal for So California, across the northern 2/3 of California, there really isn’t a strong precipitation signal in either direction for this event.  Northern California is the dividing line between the two extremes and it’s hard to say where exactly that line will fall in any given year. Klaus Wolter contends that we may be subject to notably strong and cold storm systems later this fall but La Nina’s effect on our rainfall is not clear enough for him to draw any definite conclusions.

Jan Null, a former lead forecaster with the National Weather Service who now runs Golden Gate Weather Services in Saratoga, thinks . That’s because in some La Nina years, rainfall has been more plentiful than normal. In one such year, 1999, San Francisco rainfall hit 115 percent of normal.

How’s that for hedging your bets? Just thought you’d want to know the latest predictions for this winter so you can so a little planning!

 

Autumn crocus for Fall Flowers

There’s nothing like a couple of to remind you that all things are possible with a bit of imagination. Recently I visited several inspiring gardens on the tour hosted by the Monterey Bay Master Gardeners here in our area and also saw some spectacular landscapes on the peninsula with APLD ( Association of Professional Landscape Designers ).  So many ideas-so little time. Here is just a sampling to get you started.

At one of the awesome gardens I visited, I was tickled to see a clump of autumn crocus blooming beneath some trees. This look alike of the true crocus provides a burst of brilliance in the fall just when you need it. Spring crocus are actually members of the iris family while autumn crocus or colchicum autumnale are members of the lily family. Native to the Mediterranean area and parts of Asia, they make dazzling patches of amethyst, mauve or white flowers in partial shade or full sun. The blooms last for a couple of weeks in late summer and early fall and the bulbs naturalize easily. These bulbs are also called meadow saffron but it is from one of their close relatives that expensive saffron spice is harvested.

Several months from now strap-like leaves will appear, growing to about a foot high, then die back- similar to naked lady bulbs.

Autumn crocus can be enjoyed outdoors or brought inside to grow in pots while they are flowering. You can even set bare corms in a saucer of pebbles like narcissus bulbs to enjoy the splendid flowers that quickly emerge.
Corms of these beauties are only available now during their brief dormant period. They make a fine addition to any garden.

At another garden, I saw a design trick that turned a mulched hillside into a path with just a couple of steps added. Paths not only get you from point A to point B, they can be part of the journey itself. In the upper part of this particular garden, the soil was mulched around the raised veggie boxes and the hillside below. A formal path with edging wasn’t needed here so a few flat stones installed as steps in just a couple of places directed you to a lower patio. The stone steps weren’t really needed but they gave the illusion of a path. Cost: maybe nothing if you can find some flat stones around the yard.

Everybody’s growing vegetables and herbs these days but not everyone wants to water and take care of a large vegetable garden. Enter the container gardening solution. In most of the gardens I visited, there were either raised beds or containers happily growing every herb and vegetable imaginable. Even the McMansion had a raised bed for growing edibles and flowers to attract bees, butterflies and hummingbirds, Think small, pick only your favorites to grow and enjoy the fruits of your labor with out all that much work.

There were so many wonderful ideas that I got from each of the gardens.  Where I met the owners, they were happy to share their ideas, techniques and even some cuttings.
 

Snails, Perennials,Compost & Caterpillars- Oh my!

It’s no secret we live in paradise. No hurricanes or tornadoes wreak havoc in this beautiful place we call home. We’re spoiled and we know it. Enjoy every minute when you go into the garden. This month there are a few garden tasks you might consider doing while you’re out  "smelling the roses".

#1 Slug & snail fall population control drive
Slugs and snails turn into egg-laying machines in fall. That’s because they know they may not survive the long, cold winter and therefore, need to lay lots of eggs now that will hatch in spring. They want to ensure that there will be plenty of offspring to carry on the important work of devouring our plants. Snails build up populations faster than slugs because they reproduce more often but both are good at adding to the population.

In fall, the average snail can lay up to 85 eggs and each slug can lay up to 100 at a shot. Apply one of the safer
slug and snail baits containing iron sulfate. You’ll never get them all, but applying bait now should help reduce the number of slugs and snails that will hatch and make your life miserable next spring.

#2 Economic stimulus package for perennials
If flowers on perennial plants such as aster, campanula, calla lily, daisies, daylily, rudbeckia (black-eyed Susan) and yarrow were smaller than normal this year or your plants are just too big and crowded, it’s time to divide them. Dig out each clump so the rootball come up intact. This will take a little muscle but think of all those calories you’re burning in the process.. Gently shake off or wash off excess soil and divide with a sharp knife, pruning shears or a shovel I like to use an old serrated bread knife for this. Each division should have leaves and plenty of roots Replant each immediately. You’ll increase the number of your plants and save a lot of money, too.

#3 Plant debris makes good…
As summer flowers and vegetables give way to new plantings, add old, disease-free plants and debris to a compost pile or bin. Compost only pest-free weeds, fallen leaves and fruit. Also mix in kitchen vegetable and fruit scraps, coffee grounds and grass clipping. Chop up large pieces so they break down faster. Keep the pile moist like a wrung-out sponge. Depending on temperature , the size of the material in the pile and whether you use a barrel composter or an open pile, compost can take anywhere from 6 weeks to 6 months to mature.

Diseased plant debris should be put in your compost can where the hight heat of a commercial compost operation will break it down. Cleaning up fallen, leaves, fruit and other debris will reduce the number of sites that harbor insects and diseases over the winter, too.

#4 Caterpillar wars
Don’t let the caterpillars get to your cabbage first. If you see small holes in the leaves or if the new growth is chewed on your cabbage, cauliflower or broccoli plants, they are probably being attacked by caterpillars. Search leaves and pick off and destroy or spray with organic BT ( bacillius thuringiensis) or spinosad  ( Capt. Jack’s Deadbug Brew )

#5 Enjoy Indian Summer. Winter will be here all too soon !
