Beneficial nematodes - use once OR twice a season
Beneficial Nematode question. Is it better to put out the beneficial nematodes twice a growing season -OR- just once.
This year we put in 2 4x4 raised beds with all new growing medium. The growing medium was Expert Organic Garden Soil - from WalMart and MiracleGro potting mix combined about 50/50. Espoma Biotone Starter Plus and Espoma PlantTone were the fertilizers used. Each bed was also given 2cuft of Worm Castings and 1 gallon of chicken manure - composted. I had a mammoth infestation of cuke beetles this year and nothing helped. I am putting the BN in early September and wondered if I should do another application in May 2010 after getting the raised beds ready for planting and then again in August 2010 for the second generation of Squash Vine Borer.
If you have used the BN please comment.
