Another hand-watering method

Hand-watering onions

Another fine temporary measure this spring (and another of the many things the trusty Kubota compact tractor can do) is our new spot-watering method. Michelle waters in a last, experimentally late tray of onions with a slightly modified, inexpensive ($5) plastic watering can that holds about 2 gallons (8 l), and has big holes for fast, high-volume output. These cans we usually plunge into a rain barrel (or snow barrel) for filling, and to speed that up, I cut a squarish opening in the top (I always forget to cut the opening to the back, so water doesn’t escape from the top when pouring when full). The trick here is that the water comes from the Kubota’s bucket, maybe 30-40 gallons (110-150 l) of it, depending on how carefully the drive.  You fill up, then head over to exactly where you want, like a movable rain barrel! The whole thing is quick and  easy, good for watering in new seedings and transplants, until I hook up the field-long irrigation pipe. Quite the luxury, in a way, but the tractor’s already there, and we gotta keep things moving along! :)

Water pipe

Irrigation pipe

A bonus this spring has been the steady rain, not too frequent, like, once a week or so, and somewhere around 1″ (2.5cm) each time. Perfect! Still, today, in the middle of a hot, sunny stretch, thoughts turned to water (not that it was ever far from mind). Out came the coils of 1″ water pipe. In our barebones spot irrigation system, there’s 1″ pipe and little 2-1/2″ pipe, endless 5/8″ hose and soaker hose, the gas-powered irrigation pump, and even 55-gallon barrels and watering cans. Not to mention, endless shut-off valves, quick connectors, and various hose fittings. For now, all that I’m looking to set up is one central line running from the well pump at the house, right down the length of the side-by-side fields, where it can feed the garden hoses. So, uncoiling we go…

The rain watch begins (once again)

Jumbo rain gauge (125 mm)

Another rite of spring on this tiny farm: setting out the (jumbo) rain gauge. I did it today. This model, with its big numbers and fluorescent red float, can be “read at 50 feet”! Or something like that. It’s…jumbo. I stake it in a convenient spot that I pass by several times a day, so I’m never straining… And it’s always somewhere in mind: Scientific Measurement meets wow-I-wonder-if-it’s-ever-gonna-rain-again (except for the occasional year of when-is-it-gonna-stop?!!—but the rainbows were nice).

No sooner does the snow go and the ground dry out enough to begin working, than it’s time to wait for rain. This gauge is calibrated in 5 millimeter increments (about 25 mm to the inch, I think in inches when it comes to rain…). It’s emptied daily as necessary, so it never gets nearly this high. Rainfall is recorded on the field calendar to keep track for irrigation (an inch a week total, rain+watering, is the rough target).

Don’t think I’ve seen it go much above 50 mm (2″) in a day, and that only a couple of times in six years. In the market garden, too much rain is at best not helpful, but too little rain is always plain…bad! Here’s to having rain every seven days or so this season, about an inch at a time, gently laid down over one partially cloudy day, followed by a few days of sun. I’m looking forward to that! :)

Bringing in the pipe

Coiled irrigation pipe

Bit of unusual fieldwork on the menu today, something we don’t do every year. Bob and I brought in about 1,000′ (305m) of 1″ (2.5cm) and 1-1/2″ plastic irrigation pipe, that ran all the way from the pond to the gate into the garden field. Why wasn’t this done in better weather, when, besides having no snow to deal with, warmer plastic would’ve been a lot easier to handle, especially to BEND? There’s no good answer, except maybe, “Didn’t think it’d be this cold and snowy so soon!” Anyhow, it got done, and probably in exactly the same time…

Tractor dragging irrigation pipe

I used the Kubota compact tractor to drag the pipe in three 300′ sections, right into the barnyard (the rope is tied to the front end loader bucket; in the pic, this is at the very end of the garden, where it meets the hay, so all that stubble is mainly long grass). Backing up down the field, I worked it from the far end for the section that lay in the unmown grass right near the fence, so that it could more easily tear its way out of the overgrowth. Then, some coiling (that’s Bob), tying off the loops every few turns with baler twine (plastic twine used to bale hay, it’s all over the place)… Easy!

Bringing in the pump

Irrigation pump at the pond

The trusty 6hp irrigation pump was dutifully hauled out to the pond in May, and never seen and barely thought of since. Besides priming it when it was first set out, it had zero use this year. That’s what happens when you get many inches of rain a month, every month, for an entire season. I could’ve brought it in a lot earlier to save it from some weather beating, but today was the day (and it’s a pretty rugged, all-weather pump). So, into the Kubota compact tractor’s loader bucket, and back to the drive shed. Test run for a while, drain the water, and it’s away for the winter!

Shifting gears for summer…

Watering in tiny tomato transplants

The spring rush is over, and fieldwork is shifting into summer mode, from mainly planting to mainly weeding and watering, and then, HARVESTING. Seedlings for the most important crops and varieties are in, although there’s still quite a lot to transplant.

Here, we’ve just finishing another 100 or so tomatoes, with Lynn watering them in (the Redhead water breaker is GREAT, delivers as much water as you’ve got pressure, while softening the flow so that you’re not smashing or burying the seedlings). Creating a little basin around each seedling makes the most of hand watering in.

In my continuing experiment with shortening seedling production time, these are the youngest toms to go out ever, a third set started at the beginning of May, with their first true leaves now just coming in!

There are also more squash, melons, and a few more toms to transplant—in years past, I’d've been concerned about the date, but I’m learning to adapt the season’s resources (time, people, irrigation capacity,…) to the WEATHER.

Keep the workflow balanced is my new first mantra, so we also spent a few hours weeding today (Ryan dropped by to help for a few hours, he’s a new CSA-er this year who is also about to move his family to their own tiny farm at the end June!), instead of rushing on the last transplants.

It’s hard to measure, but for this type of small, diverse market gardening, in this time of extreme weather, things quite often don’t work out as they traditionally should. For example, the recent rain and cold, and now, more heat, have created a situation where the dominant weeds—pigweed, mallow, and lamb’s quarters—are seemingly slow, but are in fact about to explode. Weeding now will probably save way more time and deliver more harvest than putting off weeding just to transplant a few more beds a few days earlier.

I dunno, I’m figuring this out as I go, but I think traditonal garden rules and timing have to be increasingly bent as the weather gets crazier… I guess you could say: EXCITING TIMES! :)
