Mowing 17 12 2015

We practiced contrasting traditional horticultural practices in the second half of December, one seasonal and the other not so.

Following a mild wet autumn we recorded an overnight (17th December) high of 15.6°C, slightly lower during the day at 13°C. This prolonged weather pattern resulted in steady growth of the lawns resulting in patches of long unkempt grass in need of a topping cut. The difficulty being the saturated state of the soil had prevented access with mowing equipment. With a break in rain falling and the sun shining we took the opportunity to mow the front lawns. Even gaining, for Paul, filmed mowing the Palm House lawns, national news coverage.

In contrast a ground frost overnight on the 13th December blackened off the Dahlia foliage, traditionally the time to then lift the tubers, for dry overwinter storage. Use a fork, away from the root zone to avoid damaging the rounded tubers on prising from the ground. As they are pulled from the ground give a good shake to loosen off the bulk of the soil. Collect together and store upside down in a cool environment to allow to dry out.

Dahlia coccinea

Dahlia coccinea

Species Dahlias and cultivars growing to the south of the front range, T borders:

  • Dahlia coccinea a Gardner and Knees collection from Mexico in 1993. Bright orange flowers held on a strong purple stem growing to 2 metres +. This is one of the parents of many hybrids and cultivars
  • Dahlia merckii also from Mexico, purple petals with yellow anthers, held above light green foliage
  • If you are looking for mass colour then Dhalia ‘Bishop of Llandaff’ is in full bloom. As with all Dahlias, the key to prolonged flowering is dead-heading.
