Growing melons and grapes in a cold greenhouse

Growing melons and grapes in a cold greenhouse will produce a sweet autumn crop with the advantage of creating some natural shading in your glasshouse during the summer months plus both melons and grapes produce a nice humid atmosphere in the glasshouse in the summer.

With the grapes best planted in the winter months outside the glasshouse in the soil if possible and trained through a hole in the glasshouse wall or glass

Melons are a great cold glasshouse crop, starting early from seed in January with some seed using John Innes compost number 1 or John Innes seedling compost grow on a windowsill.
Grow in pots sitting on a loam stacks on a bench inside the glasshouse on nets and wires.
They require some work using melon nets to support the fruit later in the season when it starts to swell. But its less work than growing tomatoes

Links to wires

To secure plants to a wall, fence and glasshouses etc we use a system of wires which we have found to be long lasting tidy and not expensive here is some links
