Seed Starting 101: What You Can Start Indoors Right Now

Winter may feel quiet in the garden, but it’s actually one of the best times to get a head start on the growing season. Starting seeds indoors during winter allows gardeners to stay connected to planting while outdoor beds rest and temperatures remain low. With the right setup and a little patience, many plants can be started now and be ready to thrive when spring arrives in northern Maryland.

At White House Nursery, winter is a natural time for planning, learning, and preparing for the months ahead.

Why Start Seeds Indoors in Winter

In Upperco and surrounding areas, the average last frost typically falls in mid to late April. Starting seeds indoors during winter gives plants a strong head start, resulting in healthier transplants and earlier harvests once it’s safe to plant outdoors. Indoor seed starting also opens the door to a wider variety of plants that benefit from a longer growing season.

Seeds You Can Start Indoors Now

Many vegetables and flowers are well suited to winter seed starting. Cool-season crops like lettuce, spinach, and kale can be started early for spring planting, while longer-season vegetables such as tomatoes, peppers, and herbs benefit from the extra growing time indoors. Flowers like pansies, violas, and snapdragons can also be started now for early spring color.

Starting seeds indoors gives you more control over timing, spacing, and plant selection, helping you grow exactly what you want in the coming season.

Simple Seed-Starting Essentials

A successful indoor setup doesn’t need to be complicated. A quality seed-starting mix, clean containers or seed-starting kits, and a reliable light source go a long way. Grow lights are especially helpful during winter when natural daylight is limited, ensuring seedlings grow strong and compact rather than tall and leggy.

Consistent moisture and moderate temperatures are key, and most seedlings do best in a warm, draft-free spot while they germinate.

Winter Is the Season for Preparation

Seed starting during winter is as much about preparation as it is about planting. It’s a chance to organize seeds, review garden plans, and experiment with new varieties before the busy spring season begins. Watching seedlings emerge indoors brings a sense of progress and anticipation, even while winter lingers outside.
