Gardening Update

I'm sprouting heirloom tomato and yellow squash seeds indoors. I have one tomato plant already started in the garden, so these will be a later crop. My watermelons look like a bust. I sprouted a bunch indoors and transplanted them outside. The few that came up didn't get past the cotyledon stage. I'm hoping that it was because the seeds were old, and nothing is wrong in the garden, because I plan to sow squash on the same hills. The Zutano avocado hasn't begun flowering yet. The buds are developed but they haven't opened, where the Stewart avocado has been flowering for a month. I was hoping they would cross pollinate. I have lots of bees in the garden now, it's a little later in spring and the lemon flowers seems to draw them.

I take it back, the Zutano just started flowering, and I picked a male flower and "did" some of the female flowers on the Stewart. I hope the bees help me.

The bugs in the side yard are soapberry bugs, (Jadera haematoloma) and feed off the seeds of a couple of odd (sycamore?) trees in the vicinity. They are not harmful, even to the host trees. The swarming masses of red nymphs made me a little concerned, but the description of this bug indicates it's not really a problem.
