I read the article about gardenias and have followed the project as described; however, into this will be the 4th week, and I'm noticing that some of the plants do have new growth and feel tight in the soil and there are those that the leaves are turning brown at the tips and don't feel tight in the soil. I fabricated some nice "greenhouses. " After the first couple of weeks of watering in the trays covering in indirct light, they all showed promise. I live in St. Louis, so now my weather really doesn't permit outside exposure. I've kept the lids on and off and I don't think I've watered too much, but maybe. The parent plant is huge and blooms great. Maybe it's water, too much containment or a combination of the both. Should some starts crap out, would it be too late in the year to try again? Thanks so much.
