I should have a usable area in my veggie patch by next weekend

BTW: average daytime temp is 22-24C, average night time temp is 15C

Sow beans, peas, beetroot, lettuce, to name a few.

I just planted pea seeds last night, also basil and parsley.  So have a go!

perhaps move forward a month to allow for higher temps. But then again we had those temps last week......but not this

I didn't get my allotment until end of June last year.  I dug a small patch and grew potatoes, courgette, runner beans, beetroot, toms and I think some salady stuff. 

Re planting spuds in late June, the hardest part was trying to find a garden centre with some seed left!  It was then just a case of trying to keep the blight from the next door plots from hitting my younger plants!
