NP-3 | Nitrogen Plastic Welder. The Nitrogen Plastic Welder uses hot nitrogen gas to restructure common plastic components in automotive repair â from cracked bumper cover surfaces to hinged tabs. Nitrogen is used as a shielding gas to prevent the plastic from burning during the weld process â producing a strong, lasting weld.
Plant the Shasta daisies in commercial potting soil or a soil mixture made up of 2 parts loam, 2 part peat, 1 part compost and 1 part perlite. Stir in a half-measure of 14-14-14 ratio fertilizer to provide a nutritional boost.
If it is planted in poorly-drained soils, the Shasta daisy will almost always die of crown rot. Plant the seeds 1/8-inch deep in the soil. Plant them in late winter or early spring before the last frost. Space the seeds 12 inches apart. The seeds will germinate in about 10 to 20 days.
