I am in central Pennsylvania. The weather here has been mid to upper 80's and humid with a short burst every now and then in the 90's. My water temperature stays up, except, right after I top the pond off but, it doesn't take long for it to recover. The water lettuce is growing leaps and bounds for me and the hyacinths are healthy and happy. I don't know what is the usual time of the year for these things to bloom because I just started my pond last August and my growing season was short last year, however, I did have hyacinths blooming like crazy in August and they were not particularly crowed in there last season as they didn't have time to spread that well. I am putting pond tabs into the lilies each two weeks and am noticing just this week more buds are beginning to form in the plant now, instead of just pads. I am going to send pictures as soon as I have some since I have no names for my lilies as the landscaper that built my pond put the initial beginning flowers in it and did not tell me what type of lilies he was giving me, and, the one I put in this spring certainly isn't what the tag had it named. I am hoping you all will be able to give me some names once I have something to submit to you. Haven't weeded out the hyacinths since I posted for help but I am going to have to thin the lettuce. It's a maniac in there. I'll remember the tip on the tomatoe sticks. I am assuming there is nothing in those that could hurt fish or frogs, right? Still need to know how often to fertlize them for sure though. Please let me know and thanks.
