Medlar Hybrid

I have mentioned previously an unusual Midland Hawthorn and Medlar hybrid in Centre Vale at Todmorden. It has flowered profusely for a few years after releasing from the heavy shade of Rhododendron but has never produced any fruit.

However this Autumn there is a branch that is full of berries, perhaps for the first time in decades. Each contains 2 seeds.

If you want to grow from seed, they have double dormancy and below are instructions from a website I consulted. I think patience is needed as the process takes 2 years!

To begin with the seeds require a cold period to break the final part of the dormancy, this is achieved by placing the bag [with seeds in a soil medium] in the fridge (4 Celsius or 39F) for around 52 weeks.

Next the seeds require a period of warm pre-treatment and need to be kept in temperatures of around 20 Celsius (68F) for a period of at least 36 weeks. During this time make sure that the pre-treatment medium does not dry out at any stage or it will be ineffective!

Following this, the seeds require a second cold period for around 17 weeks. Towards the end of this period it is quite possible for the seeds to germinate in the bag at these temperatures when they are ready to do so, (it is worth checking the bag every few weeks for germinating seedlings) if they do, just remove them from the bag and carefully plant them up.

The shape of Oak leaves

These are Sessile Oak leaves all growing from the same small branch.

I don’t think I have seen such a variation in shape, from huge leaf with shallow lobes to smaller, very narrow leaves with hooded lobes, resembling Turkey Oak.

Oaks are so genetically diverse and the Sessile characteristics can merge with Pedunculate, making it difficult to identify hybrids.

It is always recommended not to identify using shade leaves, or the mid-summer Lammas growth, as both these can produce oddities such as in the photos.

Elm

I have noticed Dutch Elm disease has taken hold of semi-mature Elms this summer in Todmorden.

Affected foliage is wilting and dying progressively from the crown downwards.

I have seen younger Elms affected by this disease over the last couple of years but it now seems to have got more serious.

Has anyone noticed Elms down the valley with signs of DED?

We still have many old Elms that escaped the last serious outbreak of 25-30 years ago.
