I have discovered that in the garden, as well as in life, where there is something beautiful or useful, there will be enemies who want to tear it down. I haven't noticed too many animals eating the weeds if there is anything more tasty around. And in both life and the garden I have to deal with the invaders.
In the picture you will see some yellow flowers, calendula (or pot marigold). The deer love them and eat the blossoms whenever they are hungry and the flowers are blooming. They seem to have no interest in the leaves. The plant in the foreground with the small purple flowers is hyssop. Around the plants you will see wire mesh that's supposed to go in the yet unbuilt raised beds, at the bottom, to keep gophers out. I'm using them here to keep the deer from stomping on my newly planted seeds and seedlings, on their way to munch the flowers.
To solve the hornworm problem on my tomatoes, I finally got some BT and sprayed the plants at dusk. And none too soon. Tonight I saw signs that yet another plant was infested, but I couldn't find the worms. So I hope I got enough BT on the leaves. I guess I'll have to spray every couple of days to keep them away. Tomorrow is busy with things outside the home, so I'll barely just have time to water. I wish more of the tomatoes would get ripe. So far I've only been able to pick from three out of six varieties. The heirlooms are getting huge, but not red. And I believe they are supposed to get red.
