Hi, I am growing globe amaranth in zone 7b, it has been growing since May and increasingly I am seeing these interesting “multi-flowers” where it looks like several flowers are all bundled onto the same head.

Cucumber plants not flowering

I have several cucumber plants. One is producing flowers and seems to have both male and female flowers. The others were planted later because I had something eating off the entire plant about 2” above the ground. The late plants have no flowers at all. They get lots of sun and I water the base of each plant daily. The wire mesh you see in the pictures was completely covering the later plants from the time I planted the seeds until they were starting to get crowded. This was done to keep away whatever it was eating the young plants. Then I opened it recently to allow them to grow.Thank you for your help!

Killing pine trees in northeastern Oklahoma

I have noticed beautiful pine trees dying in our area just north of Tahlequah along Hey 82A. In only two days I have seen perfectly healthy looking trees turn completely brown. We have ants on our trees but I am not seeing any other insects. I did see sap running down the trunks higher in the trees. What is killing them?
