U-boats. U-boats were German submarines that caused havoc in World War Two during the Battle of the Atlantic. U-boats were so damaging that Winston Churchill commented that it was the only time in World War Two that he thought Britain would have to contemplate surrendering.rom 1918 on, Germany was technically not allowed to have submarines or submarine crews. However, no mechanisms were in place to stop research into submarines in Germany and it became clear that during the 1930âs, Germany had been investing time and men into submarines.
Mountain laurel thrives in well-draining, acidic soil with a pH ranging from 5.0 to 5.5. Use a soil pH testing kit -- available at garden centers or home improvement stores -- to test your soil. If the soil in the planting area is higher than 5.5, mix 1 to 2 inches of sphagnum peat moss into the soil's top 6 inches.
Many plants are adversely affected in terms of blooms when they are over-treated with nitrogen. Yet another suggestion is that it be pruned. Your plant is already past the bloom period in this part of the country. The mountain laurel produces flowers only on one-year-old wood. Pruning now, getting out weak branches, trimming off long, thin stems, and general cleanup should propel it into blooming on that new wood that will sprout after the trimming.
