What to plant in April
Everything accelerates. Tulips flower, tomato seedlings need potting on and hardening off, new strawberry runners go into prepared ground, and the monstera puts out its first new leaf since October.
These are Northern Hemisphere months. If you garden in the Southern Hemisphere, the equivalent month is October.
