Know your Frost Dates



In a previous post, I mentioned taking full advantage of your growing season by knowing your latest spring frost and the first fall frost. After more research, I have realized that the link I provided to gather this information is not very complete. I have since found a better reference.

Go to this site to get more complete information of frost dates for your area. This site provides data for three different temperatures-- 36, 32, and 28 --and three different probability levels. I would avoid the 90% column, as most seedlings can't handle frost. Cold hardy plants can be put out in the 50% probability date, and everything else should wait until the 10% date. There is still a 10% probability of a frost, so you should always be prepared to protect your new plants should a cold snap hit.

The above site will also list your freeze free period, in days. It's important to understand this number because it defines your growing season. The length of your growing season determines what you have time to grow or how many harvests you can squeeze in. For my area, my freeze free period is 134 days, at 50% probability. What this means is it will be very difficult to grow plants that have long times to maturity, like cabbage and broccoli. Time to maturity information is provided on most seed packets, but you can also go here for days to maturity on most common vegetables.

In order for me to grow tomatoes and peppers, I need to start seeds indoors so that as soon as the danger of frost is (mostly) over, I already have seedlings ready to be planted.

For those of you planning to start seeds indoors, NOW IS THE TIME for most areas. This will be my weekend project; I can't put it off any longer. Now get planting!!

Lawns Are So 19th Century

As Spring comes nearer, many homeowners are getting ready for the yearly resuscitation of their lawn from the long winter's nap. They are preparing the sprinklers, the fertilizers, the de-thatchers, the aerators, sharpening and tuning lawn mowers, etc. But I have another suggestion: Get ready to kill you lawn.

Ok, everyone put down your guns and sickles. Take a deep breath and hear me out.
 
When I lived in Arizona, having a lawn was a luxury. Not only do you have to contend with the concrete-like soil (caliche or hardpan), you have to water at least once  a day and over-seed with a winter crop every fall. In other words, it just wasn't practical. It is very rare to see a lush lawn in Phoenix except on a golf course (and there are plenty of those). Most people landscape with cacti, gravel, and fruit trees. Unfortunately, some homes landscape strictly with rocks, giving rise to the term "moonscaping". Some moonscapes even use unnatural colored rocks, like blue or chartreuse. But this approach is not what I am advocating.

Having spent those years sans grass changed my way of thinking about lawns. A lawn is, quite simply, a stupid thing to have. You can't eat it. You have to water it constantly. And to top it off, you have to, uh, top it off (mow it). Believe it or not, but grass is the largest crop grown in America, and it is pointless. The only thing it is good for is it's nice to look at and walk on.

Many people will claim they have lawns for their kids to play on. But let's be honest: how many kids are actually out playing in their yards? In my neighborhood, which is a very typical middle-income, working class neighborhood, most of the kids are either inside playing with their Wii, or outside playing on the street. The only people I see walking on the lawns are the fathers pushing their mowers across it.

I believe the American lawn has gained the status of the fabled 1970's living room, which became a showcase for the nice family furniture and decor, but nobody ever "lived" in it. The same is true with the lawn: we expend huge amounts of time and resources simply to admire it from our kitchen windows. It's something every home owner thinks they HAVE to have because your father had one, and his father had one, and his father....

If you go back enough fathers, you'll likely end up in Europe and England, where we can squarely place the blame for our lawn love affair. But realize that across the Big Pond, it is mostly cool and wet--the perfect climate for a lush lawn. And back in the Victorian era, when gardens and lawns really became popular, many people had sheep to crop the lawn. Last I looked, my HOA doesn't allow sheep, and try as she might, my dog tends to throw up anything she eats.

In the 21st century, we have growing concerns about the upkeep of lawns. Water is a precious resource in the West and Southwest, and it is becoming more and more scarce and expensive. If scientists are right about their global warming predictions, the West will get even drier. The other obvious resource in jeopardy is the gasoline to power our mowers. And please don't forget the noise and air pollution caused by these mowers. Many of my otherwise lovely Sunday mornings have been spoiled by the incessant drone of lawn mowers and their putrid exhaust.

I used to have neighbor who specifically picked out a one-acre lot on a cul-de-sac so he could have a large lawn. Sure enough, he has a huge back yard, where 95% of it is grass. This man spends as much time and resources on this "crop" as a small-scale farmer. But whereas a farmer can take his crop to market and reap the rewards of his hard-earned efforts, my poor neighbor mows his lawn every week and puts the grass clippings in the trash. Isn't that wonderful? Think of the time he could save if he cashed his paychecks into $1 bills, ran them through a paper shredder, and then put those in the trash. So what about his kids? They spend most of their outdoor time playing in the street.

Hopefully you are getting the idea of how ridiculous and irresponsible it is to keep a lawn. I don't wish to insult those of you who have a wonderfully manicured lawn, which is something you undoubtedly take great pride in. Heck, even I have a lawn, albeit a small one. My intent is to get people to rethink their lawn. Please don't accept a lawn as the status quo. Is it really necessary, or is it there simply because you think that's what you're supposed to have in your yard?

In this era of "green" homes and yards, the lawn is the #1 evil in terms of waste. It's time to think about evolving your ideas of what a typical American yardscape should be. In future articles, I will present some ideas I have learned about this yard revolution. I invite others to share their ideas and what they have done.

In the meantime, here is a web article by Sunset magazine on this very topic. Included are 14 ideas of how to transform your yard to a lawnless oasis:

Spring is Here (Almost)

Here on the High Plains, our first sign of spring is this:


It is not so much the blooming Johnny Jump Ups, as those tend to bloom all year long, but rather because I was able to go outside in my shirtsleeves and lay on the grass to take that picture. That's not easy to do in winter.

But the other signs are the daffodils and tulips poking up out of the soil:


They are always eager to bust out of their dark confines and see some snow, which will invariably come before spring is really here.

These are the signs that get me thinking about starting seeds, and this year I intend on intensifying my indoor seed-starting efforts. Having such a short growing season means I need to have seedlings ready to go by mid-to-late May, the last frost for the area. That's only 10 weeks away!

If you want to figure out your average last frost date, the Victory Seed Company has a few web pages that can help you out. Check it for your area here. To maximize production and harvest in your garden, you want to make full use of your growing season, which is defined as the time between the last frost date in the spring to the first frost date in the fall.

If your growing season is quite long, you can sometimes squeeze in two harvests. Scallions, for instance, is one plant that I can stagger and have a continuous supply for months. They even survive outdoors throughout the winter, although they don't taste so great come spring.

This year I will focus on those plants we either eat a lot of or what tends to be very expensive in the stores:

  • scallions
  • lettuce greens
  • spinach
  • tomatoes
  • bell peppers
  • soy beans
  • sugar snap peas
  • herbs

I also want to try some odd plants that I've never grown before, like chickpeas, adzuki beans, and black-eyed peas.

The nice thing about gardening is that is it relatively inexpensive to start from seeds, thus making it economical to explore and try new things. Some seeds are even "free". My entire bell pepper crop last year was provided by seeds inside one store-bought bell pepper. Imagine that! You can actually plant those things that usually end up in the trash! In a future article I will discuss how I preserve seeds for later use, and what I do to kick-start them back to life.

Starting seeds indoors can be just a simple little operation in some neglected corner of the house, or it can be full-scale madness, with lights and heated benches and irrigation systems. I'll discuss some of the techniques I use in coming articles. So stick around; lots of cool stuff coming!
