Did you plant tulips this year? My greatest tulip achievement (man vs squirrel) was when I planted my bulbs in pots. I planted two large Martha Stewart for Kmart classic pots with Apricot Beauty and left them outside over the Winter on the sunny side of the house.
The trick was that I covered each pot with 2 layers of bricks. The squirrels couldn't get the bricks off to dig down and eat my bulbs! Hallelujah.
I have had my share of tulip-tastrophies too. Note to self: If you make custom-fit wire screens for the inside of your pots to keep the squirrels out, you have to remember to remove the screens from under the dirt in the Spring or your bulbs will be trapped! I kept waiting and waiting and couldn't understand why no green sprouts were coming up. By the time I realized my mistake, the bulbs were beyond saving. The next year I was back to bricks!
My point is, don't be discouraged if you have tulip challenges. Be creative...and then write yourself a note on your calender so you remember what to do in the Spring! The result is SO worth it!
