Monty plants up a very large pot which he stands on chocks which will help with the drainage. The pot will have a lot of plants and will make quite heavy nutritional demands, therefore Monty advises that it is important to think about which compost to use. Monty uses peat-free potting compost, sieved garden compost, leaf mould and grit in equal proportions. He plants the pots up with a canna, dahlias, petunias and osteospermum. Carol Klein looks at blossom this week, firstly in Moreton-in-Marsh and then travels to Batsford Aboretum in Gloucestershire where she meets Head Gardener, Matthew Hall who shows Carol the National Collection of Village Cherries.
