Hopefully when we get some decent sunshine the plants will green-up a bit. I have given them a dose of general-purpose plant food, which will also help.
In that tub there are presently only two cucumber plants, (one each of "Diva" and Mini Munch") but I plan to add at least one more in due course. My "reserves" were grown indoors and have become very leggy, so I don't think I will use them. Instead I sowed a couple more about 10 days ago, so if either of those develop into strong plants I will use it.
The "Reserves" have gone leggy
As you will have seen, I have also erected the support mechanism - some bamboo canes pushed into the soil of their container, and held together at the top by a purpose-made plastic ring.
Have I been over-optimistic in using 7-foot canes?!
Actually, I think not. I have grown cucumbers like this before, using 5-foot canes, and I always have to stop them when they reach the top. So this time I plan to have an enormous tower of cucumbers! The grandchildren will be happy if I do...
