Things to do in April

  • Help prevent damping off of seedlings by providing adequate ventilation.

Question of the Week

For the last 8-10 yrs I've been good about pruning my climbing rosebush and its has thrived. This year I didn't get to it in February, as I usually do, now it's April and not looking great. Will it harm the bush if I do my usual pruning in April?
