We're on the edge of the growing season. The sun's returning, days are lengthening, and soon the first big sowings begin. Before that rush starts, take a week to get your greenhouse and cold frames clean, organised, and ready for action.
Main Topic
A tidy, bright, and well-ventilated space means healthier seedlings and fewer pest problems later. Preparation now saves you time and frustration when spring hits full speed.
This week's key tasks:
Pro Tip
Lay a thin layer of gravel on your greenhouse floor. It improves drainage, adds humidity, and reduces muddy mess when watering.
Mini Q&A
Q: What's the best disinfectant for cleaning greenhouse surfaces?
A: A mild solution of horticultural disinfectant or household bleach (1 part bleach to 10 parts water) works well. Always rinse thoroughly before bringing plants back inside.
Quick Tip of the Week
This Week's Tip
