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.
All types of laurel should be planted between 2 and 3 feet (60-90cm) apart. If you want a quick screen then plant your laurel hedging plants at 2ft apart but if you are willing to wait a bit longer, you will get just as dense a hedge by planting at 3ft apart.Often a good compromise is 2'6 apart.es, prune it hard back in late spring or early summer and it will re-shoot quickly. You can reduce the height and width of all types of laurel. Don't prune it back hard if the soil is very dry or the weather is very hot.
