This warm humid weather is definitely helping plant growth, most especially that of the cucumber and gherkin plants in the greenhouse. Each day brings an extra two to three inches of height and I can see that they have the ability to take over their habitation. They are certainly gross feeders. The fruit are beginning to swell so it won't be too long before the first cucumber sandwich of the year.
Despite their resemblance to Wyndham's triffids I have always found cucumbers very satisfying plants to grow. I suppose it is their speed of growth and their productivity. Twenty pounds of fruit per plant is easily achievable from the three cucumber plants (variety: Telegraph) which I have growing. The gherkins (variety: Cetriolo) won't produce the same weight of fruit but the numbers of fruit will be much greater.
