I need a little help, getting 12 - 5' pear and apple bare root trees next week, a guy advised to put each in a potting soil pot by my house for a year so they get a good start and so the tops are higher than the deer can reach when I put them out. Good idea or not? How big of a pot? FYI, I have a two hour drive to water the trees once I plant them in the ground so half the bare root trees I planted in the past died from drought and deer damage. Thanks in advance.
