Check cordon Tomato stems regularly, tying them in to canes or strings as they grow, remove side-shoots to ensure the development of fruit not extra foliage.
Feed regularly with a balanced Tomato Food and keep compost well watered, drying out can prevent plants from taking up sufficient calcium which causes blossom end rot.
Regularly tie in stems of Indoor Cucumbers to the cane and pinch out the tip once it has reached the top of the cane and has 5 or 6 leaves.
Pinch out the shoots from side branches holding fruit, leaving two leaves after each. All female varieties will produce fruit on the main stem, so laterals can be removed altogether.
Make sure there is adequate ventilation in the Greenhouse at all times.
