These are 1 to 2 year old "Thornfree" blackberries bought from the nursery: there's 30 of them.
I ordered them 1 month ago but the transporter first shipped them to the wrong state (sic) and now i'm stuck with them for the rest of the season.
The roots are plentiful but there's dried compacted soil on them and i suppose i need to take it off before planting in my garden.
What are my chances of success ? I'm planning on mulching with straw after putting them in the ground in order to retain some moisture.
Is watering my main problem now ?
Can i hope for them to survive the high temperatures ? Or should i put them in containers until next spring ?
Also, would some of my leftovers IBA rooting hormone be of any use ?
Thanks for your help.
