Growing local

My Palagonite experiment


You may remember that I planted out two identical "Rouge De Marmande" seedlings, each in a wheelie bin with identical growing mixes, except that in 1of the bins I mixed in an amount of Palagonite mineral powder as well.


Initial growth was similar and now that they are reasonably large plants I cannot see any significant difference in them. they are both very healthy looking, and the only difference worth noting so far is that the non Palagonite enriched plant is flowering already and has formed small fruit while the other is a week or two behind in this.


So growth is no different, flower and fruit formation is a little different but probably not of consequence as all plants may exhibit slight differences this way. Will the fruit taste any different? Will one crop significantly more? Will one be more pest affected?

Will the one that has delayed fruiting end up being a better all round performer?

 Watch this space!!


The two bins are at the rear, the ones in front have spuds in. The Palagonite bin is on the right and the other next to it on its left. Both are the same height.

Sometimes I do and sometimes not. With these I have decided not to prune, because (a) I read that pruning reduces the yield, but more importantly (b) I also want these to be treated exactly the same and so if I prune them I might not prune them identically.

My pruning usually is designed to remove growth from the bottom up so as to cut off any growth that may become diseased, which may creep up to the top, and also  to allow the plants to be watered at ground level only so that water doesn't get onto foliage and cause disease/ wilt / etc to creep up the plant. This also allows more air circulation which will cause less problems. Does anyone else prune theirs? and Why?

Yes! Very lush! Do you prune your Toms, Roger?
