As part of a project designed to sow ideas, grow inspiration and cultivate futures, 300 London schools are growing their own picnic this summer and their reward could be a £500 voucher from GardenSite.
It's inevitable that some shrubs, for whatever reason, will need to be relocated in your garden. And there is no better time to do this than in the autumn. Here, Martyn Loach describes the best way to successfully move a shrub.
They may have outgrown the space where they were initally planted, you may have re-designed the garden and they now just don't 'fit in', or you may finally admit that the shrub was planted in the wrong place.
Autumn is the ideal time of the year to move a shrub, but don't forget that this will cause stress especially to older specimens and should be attempted only if necessary.
If the shrub has been established for several years or, like magnolia, resent their roots being disturbed, it might be better to leave them alone.
Younger shrubs can be transplanted more successfully, deciduous species at any time in the autumn and winter when they are dormant, evergreen shrubs should be moved either early autumn or in the spring.
Prune out any dead wood so the shrub is easier to move, then dig a substantial hole where it is to be repositioned. It should be large enough to accommodate a large root ball. Add lots of organic matter and break up the soil in the hole.
Water the shrub well the day before and dig a trench all around the specimen, the same distance away from the stem as the spread of branches. The trench should be about one spade deep.
Start towards the shrub and extracate the largest possible rootball. Place the uprooted shrub on a piece of damp hessian to move it to a new position as quickly as possible so that it doesn't dry out.
Fill with soil, gently firm in. Water copiously and continue to water over the following weeks.
In these uncertain times it's reassuring to know that Barlow Tyrie have been designing and manufacturing top quality teak furniture for nearly a century, and they have announced several new ranges to coincide with their one hundredth birthday.
Keeping everything we offer on GardenSite fresh with the widest choice is always important, that's why David Coton recently paid a visit to Royalcraft, who offer an impressive selection of high quality outdoor furniture that we will feature next year.
It's autumn and David Coton is getting the garden prepared for the onset of colder weather but, at the same time, the arrival of spring bulbs in the garden centre is a reminder that we should also now be planning ahead for next year.
There's no doubt that television provides gardeners with inspiration, sound advice and good ideas, that's why we're all looking forward to new programmes and the return of old favourites during 2019.
