My four JBPs were overwintered nestled in to much within a plastic garden shed where I insulated the walls w/ 2" rigid foam board. It was my first winter with them so frequency of watering was definitely a bit of an unknown to me as I knew I didn't want them to sit with wet feet, but also didn't want them to desiccate. If anyone has any tips on approaching winter watering that would be helpful.
@Paradox I'll consider spraying with a fungicide. Would copper fungicide be appropriate? They have been fertilized earlier this year with some osmocote and they get approximately every other week watering with liquid fertilizer. I know I could up the amount of fertilizer i'm providing though.
@sorce Whoops, wasn't thinking when I typed up the substrate composition - it's something like 45% DE, 45% pumice, 10% pine bark. As for watering, they are getting watered twice a day at this time of year. I took those pictures right before watering in the morning. They do sit in full sun, essentially 7:30AM - 5:00PM currently. I do hope to set up an automated system in the near future as I'm starting to head back in to the office. Do you feel I need to be watering more than twice a day?
