After an usually dry April with no rain recorded at all on the Rock Farm, May started with a much needed soaking . I took the opportunity of a rainy day to relax and catch up on a long overdue book review (Call of the Reed Warbler). Rain like that is an gift not to be missed however and it was just the motivation I needed to get two new tree guards completed and some acorns in the ground before winter.
Our lock-down project last year (New Paddocks on the Rock Farm) was to divide a 6 hectare paddock into three smaller paddocks by building two new fences. It was always planned to plant trees along the new fences, which will one day provide shelter and mulching deciduous leaves to the paddocks either side.
After running the mulcher over the long grass, I put two new strainer posts in the ground 3 metres off the existing fence. At the end of a pretty solid day, I had the first tree guard finished, with acorns planted between each star picket.
I repeated the process the following day with the other guard.
We planted a mixture of Californian White Oak (Quercus Lobata) and Japanese (or Korean) Emperor Oak (Quercus Dentata). In between the oaks, I have also planted some Tagasaste seeds (Chamaecytisus palmensis). Tagasaste is also called tree lucerne, and is a good shelter and fodder tree which fixes nitrogen in the soil.
We chose deciduous trees for these tree guards because they provide good shade during summer, allow light to penetrate during winter and their leaves form a deep mulch for fertilising the soil. Adjoining this paddock is a series of four small horse paddocks. One of these paddocks has a line of white poplar (populus alba) along its northern fence. The paddock is the lushest, and greenest of the four little paddocks – a difference I can only attribute to the tall deciduous trees that provide shade and leaf litter.
If this is your first time reading our blog, you might be asking why I haven’t planted native trees along these fence lines. The answer is complex and it relates to our desire to create a productive farmland that is in balance with nature. We are not trying to re-create the landscape as it was prior to European settlement. Rather as our climate gets hotter and dryer, we believe that large deciduous trees will help shelter our property from the extremes of the weather. We have some beautiful Elm Trees (Ulmus Procera) that are at least 150 years old near an old stone cottage ruin. Their shade and mulching leaves make this area the coolest part of the property on hot days
In other parts of the Rock Farm we have planted native trees. Along the creek bank, we recently planted 300 native trees for habitat and to help stablise the bank. That marathon effort (Can’t see the wood for the trees) has been a great success, with the vast majority of the seedlings becoming established. Wombats have knocked a few over, but overall I am very pleased with the first six months of growth.
Planting trees is rewarding. Just as I packed everything up to head back to the shed, a rainbow appeared. I hope it is a good omen for the beautiful trees I would love to see grow here. As I told my boys, it is my dream that not their kids, but their grand-kids will one day be able to sit in the shade of these trees.
