Week Nine
Monday 31st October
- hedge cutting
Michael pointed out that I may be getting some pests or disease in my glasshouse, leaves of Erythrina x bidolli getting brown spots, likely to be a bacterial leaf spot.
From www.extension.umn.edu/garden/yard-garden/trees-shrubs/man...:
The pathogens that cause leaf spot diseases often overwinter in infected leaf debris. Some also infect buds and young twigs. During the growing season, wind and splashing rain carry spores of the pathogen to susceptible plant tissue and spread the disease throughout the canopy.
Most leaf spot diseases need either water on the leaves or very high humidity for a prolonged period of time (12 to 24 hours) to start an infection. Leaf spots often mature in one to two weeks. At this point each leaf spot produces spores or bacteria that can be spread throughout the canopy, starting a second set of leaf spots, or causing new infections on other plants. This cycle of infection and spore production repeats whenever weather conditions are favorable. As a result, in years with very high humidity or frequent rain events, leaf spot pathogens can spread throughout a tree or shrub's canopy resulting in severe disease.
Tuesday 1st November
- hedgecutting
- went through the plan for sympsium
Wednesday 2nd November
- First day of the Symposium. Freezing conditions. Coralie and I potted up a range of Begonias and Plectranthus from the hovel beds to store until the new year weather warms up enough to replant. We cut the plants down to roughly a foot, and kept the chopped material in a moist plastic bag in order for cuttings to be taken at a later point. We potted: Begonia 'Burle Mark', B. metallica, B. fuchioides, B. scharfii, B. luxurians, B. 'Little Brother Montgomery' and Plectranthus zulensis.

Thursday 3rd November
- 2 degrees Celcius at home. Finsihed potting up Begonias. Dug up the Tibouchina urvilleana (Glory Bush) from the Exotic garden, cut it back hard to two feet and put it into a pot.
Coralie and I pulled up the Dahlia by Jonny's gate in the High garden, the Karma Naomi's were deadheaded so they could go in the house and the tubers knocked free of soil and stored in a plastic crate. We dug the bed over, saving plants of worth. Ox-eye Daisys, Anthriscus (cow parsley), etc...
we replanted with Kosmic Kale, Myositis and intend to plant a Tulip too. The myosotis will grow and flower before the Tulip and when the Kale is smaller, as the Kale grows the Myosotis will be over and the Tulip will take over and be in combination with the Kale.
Friday 4th November
- decided on Tulip Cairo for High Garden by gate. Lightly fragranced, orange-cinnamon colour, 50 cm tall, flowers early to late April.
- Helped Lewis prepare for bulb planting in pots, gathering broken pots, grit and old soil mix.
- Group planting of tulips, narcassis and miscari into pots. Holes in pot first blocked by down turned croc, layer of grit followed by enough soil that allows the bulbs to sit at the correct height, allowing enough soil and grit to sit above, and a small difference in height between edge of pot and top grit level. Remember to firm down soil at each point.. Narcissus was double layered. My first attempt I did not leave enough room for roots, so made a deeper soil level.
- Last hour was a walk around with Kamal in torrential rain, looking at the plants in his Ident.
Cotinus coggryia, Hydrangea anomal subsp. Petiolaris, H. quercifolia, Crateagus persimilis 'Prunifolia', Malus hupensis, Vitis coignetiae, Salix alba var. sericea, Gleditsia triacanthos 'Elegantissima', Crateagus orientalis, Viburnum opulus 'Compactum', Celastrus orbiculatus Hermaphrodite Group, Catalpa bignonioides, Quercus rubra, Euonymus europeus, Cotoneaster horizontalis.
