i've been neglectful

There hasn't been too much to say about the garden in recent weeks.  I've pulled out the lettuces and peas as they were done for the season.  Now I am waiting for the zukes, tomatoes, green beans, kale, and the second planting of broccoli to be ready.  I have a serious aphid problem with my tomatoes.  I purchase 1500 ladybugs and set them free to attack the lil buggers, but they flew away.  I must now find a recipe for an organic spray.  Some suggest crushing tomato leaves and others say a garlic and dish soap spray works.  The only problem with even "safe and organic" sprays is that they will kill good bugs with the bad.
