Week three! Wow, the weeks are flying.... here are our weekly garden ideas on a budget!

A cost-effective way to fill flowerbeds with great-looking plants is to buy perennials that you can divide. This may sound like advanced-level gardening, but it really isn't. It will work with clump-forming perennials such as geums, astrantia and hardy geraniums.

Simply tip the plant out of its pot and pull it apart into two or three bits, each with some stalks and root. Dig a hole and plant each part in your flowerbed. Next year when they've grown and spread, you can dig them up and pull them apart again to gain even more plants.

You'll get a wonderful display in a couple of years for very little cash. Six geranium plants are usually enough to get going in an average-sized garden.
