Gardening Jobs in January

Greenhouses and Frames

Checking protection and warming

Insulation improves both greenhouses and frames and is easily accomplished with plastic bubblewrap. Make time to do it now if you haven’t already. Examine the heaters.


Water the plants just when the earth in the pots begins to dry up.

Avoid overwatering annuals in pots and other young plants in the nursery, as the roots may be injured. Take care not to shower the blooms or leave water in the plant tops. Attempt to water as early in the day as possible, especially in a cold or cool nursery, so that surfaces dry before nightfall.

Controlling bugs and illnesses

Remove any leaves that show signs of botrytis (dim shape) and discard any cuttings with diseased stems.
Check for irritation such as plant weevil and make a relocation if necessary. In the winter, use cleans instead of showers to avoid creating mugginess in the nursery.

Planting seeds

If you have a warmed propagator that can hold a temperature of 16-18 C (61-65 F) during germination, you may begin sowing seeds around the end of the month. Planting should be postponed for another month if a warmed propagator is not available.

Plant nursery plants such as begonias, gloxinias, and streptocarpus, as well as nursery plants such as pelargoniums, half-strong annuals, lilies, perennials, and sweet peas.

Lilies for forcing

If you want to force your lilies to bloom early, start planting the bulbs now.


Finish the pruning of plants in the garden when they are completely dormant.
Strip or perhaps even rub free bark from the stems of developing plants since this can trap pests during the winter months, but don’t remove off so much bark that green shows through.
