10 weeks is the norm from the time of planting in my limited experience.I planted some potatos about 6 weeks ago and now the green sprouts are sitcking about 6-7 inches out of the ground. So far, only 1 has been eaten. So just for kicks I dug that potato out of the ground to see how big it was....
Nothing! Just the hunk of potato that i originally planted! Guess it takes a few months for these things to actually produce.
TSC and runnings have a product call liquid fence. You can buy it premixed or mix it your self. Spray once a week for three weeks, then once a month after that.
Two years ago I only sprayed once and the deer stayed out of the cucumbers for almost the entire summer.
This stuff works!
Any updates on how your sweet tater plants are doing?I have used the liquid fence before and it works foe about a week or until it rains. I am worried as these are just a weed at this point and if the Deer even nibble on it they will pull it out.
