Give pepper the right place before you calculate dates.
Peppers are a warm-season crop with a relatively long lead time. The useful planning question is not how early you can sow them, but whether you can give seedlings enough warmth and light indoors and enough sustained warmth after transplanting.
Use a warm, bright, sheltered site. In cool climates, a greenhouse, polytunnel or protected wall can materially change growth compared with an exposed bed. Containers are useful because they warm quickly, but they also dry faster and therefore need more consistent checking.
Plan the start around the way this plant actually grows.
Pepper seedlings are often started indoors earlier than tomatoes because they develop more slowly. Germination and early growth are strongly affected by temperature. Do not compensate for weak light by sowing excessively early; stretched seedlings are not a useful head start.
Water thoroughly, then let the growing medium move away from saturation before watering again. Small pots create bigger moisture swings, so pot size becomes part of the watering plan. Stake plants if fruit weight starts pulling branches down, and avoid feeding more heavily than the product label recommends.
Use maturity as a window, then check the real plant.
Many sweet peppers can be picked green or allowed to colour fully. Leaving fruit to ripen further changes flavour and usually keeps it on the plant longer. When cool weather arrives, assess remaining fruit and forecast conditions rather than relying only on the original maturity estimate.
Work backwards from local frost risk, calculate an indoor starting window, then decide whether your outdoor site is warm enough for the variety.
How should I use the numbers on this page?
Spacing: 45 cm is the current broad planning default. Do not tighten spacing simply to increase the plant count.
Maturity: 90 days is a broad planning estimate. Weather and cultivar can materially change the real timing.
Local conditions: Frost pockets, wind exposure, soil drainage and container size can make two gardens in the same town behave differently.
