Matt W · 2nd Dec 2025

Those who are new to greenhouse gardening often think that glasshouses are best suited to growing flowers, herbs, and perhaps cool season crops like leafy green vegetables.

November feels like the garden is finally slowing down. The days are short, frosts are appearing on car windscreens, and you are probably spending more time in front of the fire than digging in the borders. But here is the truth: November is actually one of the most important months in the gardening calendar. What you do now directly affects how well your garden survives winter and how early it bursts into life next spring.

Removing dead or diseased wood prevents infections from spreading. Opening up the tree's centre improves air circulation, which dramatically reduces fungal diseases like apple scab and brown rot.

When Do Gladioli Flower in UK Gardens?

Matt W · 8th Aug 2025

Gladioli bring dramatic vertical colour to UK gardens, but timing their flowering correctly makes all the difference between a spectacular display and disappointment. These sword-like beauties have specific needs that, once understood, will reward you with months of stunning blooms.

What to Grow in Greenhouse August UK

What to Grow in Greenhouse August UK

Matt W · 9th Jul 2025

August in your UK greenhouse is about maximising opportunities. You're harvesting the rewards of summer growing while investing in winter abundance. The key is understanding that successful August growing requires active management—this isn't a month to set things up and hope for the best.

Focus on heat management first. Get your ventilation and shading sorted before you start sowing because failed sowings cost time you can't recover this late in the season. Once conditions are right, be bold with your sowings—your greenhouse gives you growing opportunities that outdoor gardeners simply don't have.
