Secrets of growing potatoes.For me, it has been much experimentation.
No matter which method I've used, the best results have come when I have been in the garden daily, checking for insect damage, signs of distress, etc. Of course, I have quit working outside the home, so have no excuse not to tend the garden.
Use minimum fertilizer, careful of the nitrogen content. Only add fertilizer in liquid form, while watering, weak solution---(MiracleGro) when dry periods come. Use granular type when planting, 10-10-10, sparingly.
Hill the potatoes as they grow. When they reach about a foot in height, quit hilling, and start mulching heavily. grass clippings, straw, carpet scraps
Watch for dry conditions so as to not stress plants, water well, but with heavy mulch, don't need very much,
Bugs---no explanation needed.
Did the container method with 4 plants, really small scale. Made a small box with wood scraps. As plants grew, packed clippings, then a shovelfull of garden soil, then a bit of chicken litter,(small amount) then compost then clippings, up the stems till only a couple inches of foliage show. Water well. Potatoes were large, and smooth, in number, a healthy lot. did not weigh as I should have to prove the method. But will grow taters agin this way. Oh, and used diluted MiracleGro as fertilizer. Plants looked beautiful, deep green.
Best suggestion is to make several small rows, and test the methods you read about and note the results. Soil differences and weather conditions etc can be taken into account.
Experiment! and good luck,Margo
