Your best bet is to keep cutting the grass (regular means there is less of it to cut) and then in the borders get a nice mix of shrubs (evergreen looks best in winter), perennials (so they keep coming up year after year) and some bedding plants in the spring for instant colour during the summer. Try to avoid high maintenance pots etc - keep to british natives which you know will flower. Find out your soil type first and then most garden centres will tell you which plants are best and will thrive. Good Luck!!
