At the beginning of the month I turned 50. My MIL gave me a birthday gift. It was a check for $500 with a stipulation that it be spent on something I wouldn't already buy. Now you might not see that as cruel, but as I'm sure you could guess, my mind immediately went to the garden. I started thinking about irrigation systems. Then I started to think about whether it was really worth putting one in or not. Oh the dilemma. I've been doing calculations and debating this in my head for weeks.
Monetarily it is a bad choice. I did the math. I'm guessing that I water the garden overhead about six times a year. We get rain here. It is not a dry spot. Our average rainfall is 4" per month, with a high of 4.5" and a low of 3.5". So I have to water on occasion, but not a whole lot. A quick back of the envelope calculation says that if I water 6 times a year I pay about $46 per year in water (which I might point out has never been calculated and never put in my tally - ah well I'm not perfect). If I had an underground watering system it may (or may not) save me about half. Say $20 per year. The inexpensive systems will cost me over $200. I haven't done the math there, and it might be more like $400. The plastic only lasts for about 8 years or so left outside. Some of the items like soaker hoses and T-tape lasts much shorter. So it is cheaper not to put one in.
The additional plastic in my gardens is always a negative too. Since it has a real time limit (the T-tape especially doesn't last long) replacements would always be coming. I'll do that for row covers as row covers save me so much time in spraying Bt, but I'm not sure it is worth it for the little watering I do.
In addition it doesn't save me any time. The system requires maintenance and construction. Setting up an overhead sprinkler is so easy. It does help with watering one section more than another. Which right now I can't do unless I do it by hand. Is it worth the aggravation and upkeep? Probably not. It might be worth it to do a small section. The circle garden and the herb garden along the house might be nice. Then I don't have to water the 3' brick path all the time (which had to be done to include that in the watering). So maybe I'll be doing about 1/8 of the garden in soaker hoses of sorts. And I do want irrigation for my rock wall garden. That place is impossible to water and takes forever to do by hand. So I'll probably put a small bit into irrigation. And I'm going to buy a really expensive but highly rated sprinkler whose width can be switched. Then I'll be able to water my whole raised bed area at once (minus the circle garden and the herb garden along the wall). Cost $89. Yes a damn expensive sprinkler. But hey I'm supposed to be buying things I wouldn't already buy.
Then there is the idea of a rain barrel. I've been thinking about a pretty one. They make lovely fake terra cotta ones with planters on top. So pretty. But then I thought about my roof. My roof is an asphalt roof. Asphalt has a ton of really nasty toxic chemicals in it. Do I really want to water my garden with that? Before I bought the house, my dream was a roof that had a material that you could drink from and an underground cistern. But I'm not about to replace the roof. And even if I wanted to, I couldn't get it past my townhouse mates. It would be very costly and their dreams are hardly the same as mine. And what a waste to throw out a new roof. I would only have done it if we had renovated an old house. So anyone know the answer? Is the water coming off an asphalt roof toxic? See the problems my MIL has caused?
An easy thing to spend it on is row covers. I've been drooling over the Veggiecare ones from Australia for years. I'd love to have about three of them for half beds. So three that would cover an 8'x4' bed. Plus I'd love some clips. Price $220 to $270. Now there is really something I wouldn't buy myself. That is a ton of money. Supposedly they last longer (about 8 years). I hope so. I hate the Agribon. With our winds it rips too easily. And the heavier stuff gets too hot in the summer and blocks too much light. This one is similar to Agribon 19 in light transmission. I'll still use the Agribon I have, but I'll use it for temporary things. Things that are there for a long time I'll use the new stuff.
Oh and I'm loving the company already. I asked them which of the clips I should be using as my pipes are not 3/4" or 1". They said they would send me a sample and I should test them. So I will. That is why there are two prices. If I get the Jumbo clips it is much more expensive.
I'm still debating in my mind but for now I think I'll ignore the rain barrel since I don't trust my food to be watered from it. I'll get the sprinkler. I'll get the Veggiecare row cover (and maybe some clips). And I'll start with a small irrigation system for the hard to water rock wall garden and the herb garden by the wall. And I'll think about the circle garden.
What would you all buy if you were given such a nice gift?
