I hope it's warm in your greenhouse. Last year, my potatoes wouldn't sprout until the temps got up near 80Ã‚Âº. I had started them using water-method mid-March, along with chitting my Irish potatoes -- Sweets with humidity cover in the sunny kitchen window (~72Ã‚ÂºF), Irish in the garage (50Ã‚ÂºF~55Ã‚ÂºF). Practically nothing happened to the Sweets until April. Slow going with the sprouts until we had that sudden heat wave in late April during which I refused to turn on the A/C.
Then they all started growing like mad.
I started planting water-grown slips 5/24. I'm going to try to plant them earlier than that this year, and am also trying both water and
soil growing with bottom heat. I'm also rooting the slips in pots of soil as they grow. I'm sure the soil-grown and soil-rooted slips will settle in faster once transplanted.
BTW, I don't know if I have the courage to prune back my single apple tree to that extent
(I'm probably being more tentative with my other, young espalier apples than I should be...
) Please keep us updated on their progress. Will you try different pruning techniques with the others or will you treat them all the same way?
