Two years ago, husband and I bought cow pots (containers made from cow manure), in which to start our vegetable seedlings. It certainly made sense, since they were advertised to fertilize the plants while they were getting started. Then the plants could be put in the garden pot and all, so they would continue to be fertilized as they grew outside.
They sure didn’t work the way the ads said they would. We had the most pitiful seedlings the last two years. (It didn’t help that last year the cat ate all the pepper seedlings before we could get them in the ground.) The seedlings started out fine, but 6 weeks after of germination their growth came to a stand still as the roots made contact with the pot, and they languished until we got them out of the pots and into the ground. It dawned on us that the manure that made up the pots was too rich and “hot” for the seedlings to tolerate. We should have known, since we put composted manure on the garden in the fall so it has a chance to really rot and cool down over the winter. The cow pots were too much of a good thing. This year we used plastic pots to start the seedlings, and they are the best we have ever started.
When have you experienced too much of a good thing? When has a product (or person) not lived up you your expectations?
