Save the honeybee

The Soil Association have launched a campaign to save the honeybee click here to find out how you can help!

One factor in the decline of honeybees has been shown to be the use of pesticides containing neonicotinoids. This topic would also provide a great letter writing activity for children which would link Literacy, Science and ICT. Click here for information on how to write to your MP.

Contaminated Manure Problem

You may be aware of the problem with contaminated manure experienced by lots of gardeners last year. If you are unaware of the problem then you may like to read the information by clicking here.

Some of you may be interested in adding your name to a new epetition. If so visit here

Also please make sure everyone you know is aware of the problem so we can try and cut down the number of new victims. I have created and posted an information sheet here which you may find useful to circulate to all your contact.

New resources now available

Now available: The Cabbage Family

Now Available -The Roots Family
Price £25 + £2.50 postage and packaging within the UK (overseas postage will vary)
These add to the resources collection which already included Peas and Beans and The Onion Family

Save postage by ordering all four resources at £4.00 for p&p - saving of £6

These Smart Notebook and PowerPoint resources are rich in photographs showing every stage in the life cycle of the vegetables that the children may grow in their vegetable patch. There are four separate resources each focusing on a particular plant family. Each resource is accompanied by original high quality photographs, (approximately 120 in Peas and Beans resource), that can be used when making worksheets or within children's work. Each resource is provided in three formats: PowerPoint version 2007 - linked to a series of Smart Notebook activities PowerPoint version 97 - 2003 - linked to a series of Smart Notebook activities Smart Notebook - contains the content of the PowerPoint versions and activities.

If you would like the resources but don't have the software to run them? Download a free viewer Smart offer a Notebook viewer, (for Windows 2000 or later, Mac or Linux), that can be downloaded from the internet. The viewer will allow interaction with the resource but will not allow any editing. Likewise PowerPoint viewers can be downloaded. All are fully editable using the appropriate software allowing teachers the freedom to simplify or edit the resources for younger or less able children. The PowerPoint formats are each linked to a series of Smart Notebook activities.

Watch out for blight on potatoes and tomatoes!!

Blight was responsible for the Irish potato famine and the period of starvation, disease and mass emigration that followed. It is the dread of anyone who grows potatoes or tomatoes - one minute you have healthy looking plants and promise of a good crop and then the next all the hard work and careful tending has come to nothing! When our allotment site was relatively derelict we rarely suffered from blight but now that the site is fully occupied this problem has increased in severity. Blight is a fungal disease whereby spores are spread by wind and rain. From June onwards is the period when potatoes and tomatoes are most likely to become affected.

The condition for spread of blight is known as a Smith period. This is a period of at least two consecutive days where the minimum temperature is at least 10ºC and on each day there are at least 11 hours when the relative humidity is greater than 90%. The potato council operates a blightwatch service click here. They have 300 blight scouts walking potato fields over the growing season and reporting on any sitings of blight. Blight regional maps are available for viewing on their website click here which show where blight has been sited. Watering potatoes or tomatoes in such a way that wets the foliage can artificially produce a Smith period.

Brown patches on leaves are the first signs that blight has affected your crops. The leaves will then curl up and wither. The problem can be that other potato/tomato problems may display similar symptoms. There are photos of blight affected potato and tomato plants here, here here and here. You can also buy a testing device to check for blight from here.

Blight can be a sneaky problem as it can lurk on seemingly perfect fruit or tubers. Tomatoes that appear unaffected can start to rot five days after they have been picked.

It's almost impossible to prevent blight but there are precautions that can be taken. Avoid planting potatoes and tomatoes in the same areas in two consecutive years as spores can be present in the soil. Leaving affected leaves and stems lying around can also increase the chances of passing the disease on. Earthing up can make it less likely that the spores will infect the potato tubers. Another alternative is to grow early varieties of potatoes that will mature before blight conditions prevail or to try some varieties that are supposed to have some degree of blight resistance. If anyone has any experience of varieties that have seemed to weather the blight storm please share your experiences by posting a comment.

A protective fungicide can be used but this needs to be applied before blight is apparent and spraying has to continue every 10 days after the first application.

If your potato plants do succumb to blight then remove and burn the affected foliage - it is possible that the spores may not have reached the potato tubers. After removal of the foliage leave the tubers in the ground for at least two weeks. During this period spores on the surface will hopefully be killed and lifted potatoes may avoid being infected. Once lifted you will need to keep checking the tubers for signs of blight and dispose of any that become mushy or have dark patches on the skin.

Tomatoes grown in greenhouses are afforded a little protection from wind borne spores, however if spores do enter the greenhouse the disease will thrive in the warm humid conditions. It is also extremely likely that tomatoes will be grown in a greenhouse year after year and so any spores remaining in the soil may be more likely to spread the disease from one year to the next. Removing the bottom leaves of tomato plants can help in that plants can be watered directly on the roots thus avoiding any splashing onto the leaves.

After today's rain, I guess for now it is just a matter of sitting tight and keeping everything crossed.
