Plague and pestilence - a thoroughly disheartening affair

How dare we have a holiday!
We were only gone for just less than a week during which time a plague of pestilence and disease was wrought upon the smallholding. Well, that's a bit of an exaggeration but this is a post to show that smallholding is not always a bed of roses.

On the positive side the animals were ok. But it was a different story in the veg plot.

Blight
For the umpteenth year in a row blight has swept through my potatoes and moved onto my tomatoes. And because I wasn't here to spot it early it had a chance to kill off all the foliage on the Earlies and Second Earlies before starting on the Maincrops. There were no signs of it when we left for Scotland and by the time we returned it had ravaged the crop. The timing could not have been worse. I took the tops off all the potatoes and have left them in the ground so they don't come into  contact with any spores on the soil surface, but harvesting has been a thoroughly depressing activity, with perhaps just a quarter of the Early potatoes surviving. I haven't yet dared check the other potatoes, but am clinging onto the hope that Charlottes have been pretty blight resistant in previous years.
The blight has then moved onto the tomatoes. It enters the plants through the leaves so I have removed most of the leaves and check daily, removing all affected leaves and fruit. But once it gets into the stem you are fighting a losing battle. For some reason the plum varieties, Roma and San Marzano, seem to fare the worst. A fairly decent crop can still be salvaged from the others.

Spanish Slugs
Next on the list is slugs. More precisely the big fat orange ones which some people call Spanish slugs. The problem is they are too big and slimy for natural enemies to predate. I think the key to controlling them is to leave them no cover, but this means keeping the veg beds perfectly edged. The most effective killer of these orange slime-monsters is my edging shears - messy but effective!
Unfortunately they also seem to like living under a dense canopy of nasturtium leaves and whenever I have let these companion plants ramble it has resulted in an army of slugs attacking the crops.
So habitat destruction is proving the key to control here, as well as direct hunting out of the enemy followed by quick dispatch.

I have also released the ducks into the spare veg patch where my brassica leaves are more hole than leaf. This is in the part of the smallholding which used to be arable with the result that there is very little topsoil. The clay surface opens into wide cracks during the summer, a perfect daytime hideout for the slugs.
During my research of Spanish slugs I have come across an awful lot of poor advice on various forums, but one comment I read has reminded me of a technique which could possibly work. Apparently slugs are suckers for porridge oats, which then swell up inside them with disastrous consequences (for the slug).
I can buy sacks of porridge oats for just a few pounds and have some in stock, for the sheep love them soaked and mixed in with a few sugar beet pellets.  I would imagine the ground needs to be dry for this to work well and the oats to achieve maximum swell inside the slug, so now would be a perfect time to try.

Red Spider Mite
Third on the most unwanted list is Red Spider Mite. I nuked the polytunnel this winter but they have crept back in, though much later than in previous years. I am managing to keep them under control with weekly sprays of pyrethrum on to the most affected plants and sprays of rosemary oil mixed with eucalyptus oil and a little soap every other day in between. The trouble is you can never quite totally eradicate them.
While we were away they multiplied rapidly in the polytunnel, moving from the aubergines (always the first to be hit) onto the cucumbers (always the second). However, I have been working hard and they are back under control for the moment.



Well, that was a depressing post wasn't it. But we came back from our holiday refreshed and full of optimism. The disappointments have been shrugged off and we have been forging ahead with new projects. Hence the lack of posts recently. We really have been working very, very hard till late every evening.
More on these exciting new projects very soon.
