Made up several plant protection rings this morning. I had a 4' piece of 16" plastic culvert left over from another project years ago. One end was damaged good so cut the rings about 10" high with the saws all. Put them four around the tomato plants. The neighbor put in a bunch of field drain tile last year. The drain tile companies use a 6' piece of 24" plastic culvert to wrap the drain tile around to make 100' rolls. The core is usually discarded as it is to short and to small for any culvert type use. I got one free from my neighbor and cut it into 12" high pieces. All the vineing type plants are planted in a mound about 3' across the bottom and a foot across the top. I drop a piece of the 24' culvert over each hill. This keeps the wind from beating the plants to death and the rabbits don't get to the young plants and wind won't blow the rings away. Permanent as will last a lifetime and total cost is 0. As soon as the vines reach the inside of the rings will remove them.
