The start of February is a significant time of the year in two calendars. Jewish tradition celebrates Tu B'Shevat, the New Year for Trees, from sundown. And in Celtic traditions, Imbolc takes place at the same time, celebrating the first signs of spring.

So what better time to gather for another fantastic planting session with The Orchard Project and Earthwatch Europe? This time we met in Stoneyfields Park, a lovely green space in Edgware, with a beautiful waterfall and lots of mature trees along the banks of the Deans Brook.

In a muddy corner of the park, our hosts had set up a marquee and brought the usual wintry fare: mulled apple juice and cider, shovels, fruit trees and bushes, mulch... As with our earlier orchard planting session with them at Hollickwood Park, we were there to provide an extra bit of physical oomph for the other volunteers - of which there were over 20!

Many hands made light work of the ten trees going in the ground: 4 apples, 2 pears, a plum, a mulberry, a sweet chestnut and a crab apple. There were around half a dozen berry bushes too. After an informative explanation of the process by orchard expert Daniella, we set to the task.

A great tip: if you plant your trees in a circular hole, then the roots will curve around in a spiral and not spread out properly. But if you plant in a square hole, they spread out faster and the tree will root stronger!

Despite rain, mud, and only one boshing device (a 'rammer') for getting the stakes in, everyone worked together brilliantly and we were done in a couple of hours. Then, after a bit of a snack and some apple-based beverages, we cleared down, admire our work and celebrated the start of spring.
