Don't understand - if they are going into a greenhouse, why are they still indoors? I know that I keep saying 'don't rush things', but mine go out any time from mid-April to end-May, risking setback through frost, & produce their first anywhere between early June and mid-July.
Cherries are early, beefsteak take the longest.
Despite all that, mine are still in the lean-to, which is warmer than the big one, because they just haven't made a decent enough root ball to go into their final positions.
