Spring seems to gather momentum in October. In the colder climates, this is really the beginning of spring when everything awakens from the cold winter chill. Blossoms abound and flowers bloom in gay abandon. The rains arrive and spoil the party but are heralded as the time to signal the new planting season. Prolonged periods of wet weather and cold temperatures are often a feature of October weather. Plants grow rapidly and weeds do too. When the sun comes out, the garden often seems overgrown!
- Remove primula malacoides plants as they come to the end of their flowering season. Shake the removed plants over the soil to scatter seeds for next season.

- Sow sunflower seeds.
- Impatiens (the New Guinea type) and begonias are the most popular summer flowers.
