>>618652When it comes to irrigation, just keep it simple and use the finger test.
Before, and after watering, insert your finger about two inches deep into the soil.
When checking after watering, if the soil is consistently moist throughout, then you've watered enough. If it's very saturated, and mucky, then you've watered too much. If the first inch or so is moist and the remainder is dry, then you aren't watering enough.
When checking before irrigating, you're just checking to see if your irrigating often enough. If it's consistently, or even somewhat moist, then it's often enough. Dry? Not often enough. Mucky? Too often.
I work on a farm professionally, and we use the finger test because it's the most reliable method we've found.
Here's a little trick. Water in the evening, and the soil will stay moist through the night, giving plants and seeds plenty of time to absorb water before it is lost to evaporation or gravity.
Also, we use similar plastic netting for our peas. The bunching at the bottom doesn't matter.
Good luck anon.
