am having problems w/bulbs and perennials planted in a new planter. i get a few leaves about 4" tall from the tulips, and only a tiny flower bud at soil level. i dug up the bulb and the roots are only an inch or so long, and square on the very tips. someone said my soil has nematodes that eat the roots, thus stunting/killing the plants. this happened to all the bulbs/perennials planted in this bed. the annuals and dahlias i planted last summer thrived and were gorgeous, but everything i planted in the fall for spring blooming is purt near toast. i can't find any info on nematodes. does anyone have any ideas? they are not freezing, they are not planted too deep; the roots are being eaten or something, as they are very short, and none of the perennieals have even made a showing; i think something demolished their root system, too; can't even find them. i find this so odd since the annuals did so well.thanks
