Seeds to Sow: Early April

20150401We’re now in the heart of seed-sowing season. It’s time to start seeds of many vegetables, annuals, and perennials.

  1. I think that what you composed was very logical. But, what about this?
    suppose you typed a catchier post title?
    I mean, I don’t want to tell you how to run your blog, but suppose you added something to possibly
    get a person’s attention? I mean Seeds to Sow: Early April
    – Laidback Gardener is kinda boring. You ought to peek at
    Yahoo’s front page and see how they write post titles to
    get people to click. You might add a video or a picture or two to get readers interested about what
    you’ve written. Just my opinion, it would bring your
    posts a little bit more interesting.
