Q.I Planted Tomatoes In A Plastic Tote And Algae Has Formed. Can I Save The Plant By Putting It In The Ground ?
The container does not have drainage so should I drill holes on the sides?

Both options are viable! Algae on its own is not a problem, but it does signal that the soil does not drain. Catching it, now, will save your plants.
Personally, I would opt for drilling drainage starting 1/3 of the way down the container, and continuing down and around to the bottom. Then I would make sure that it is dry down to about 1/3 of the way down into the soil before watering again if possible.
Otherwise, transplanting is a viable option, too!
