We have a bit of sun, so time to look over plants for any issues. Well found a few Aphid; gave themselves away by the honeydew and mould appearing on leaf surface. The warm, moist atmosphere in the greenhouse keeps those little problems growing, slowly but growing. So regular checks help you keep any problems manageable.
Then there is the benefits of having plants all year-round, finding those new shoots which show bud trusses for next summers fall crops. When you need a break there is always a snack close by.
Shape pruning is easily done at any time, if in doubt wait for the new growth and see which are bud trusses and which are shoots. Then act and snip to create your ‘perfect’ shape.
