Brambles are the great invaders of the woodland garden. Once grass cutting is complete the plants which have brambles growing up through them will be obvious and, armed with a really thick glove, now is the time to pull them up at the roots. If left alone brambles will soon cover and smother your best shrubs especially in corners of the garden where you are unable to mow or cut. Even in a hot summer brambles will continue to grow at an alarming rate. The best solution is to hand pull the whole root system from ground level. Cutting them off will see the problem recur next year.
