A lovely crop of sweet peas! — Sow sweetpeas and plant *Narcissus* bulbs for beautiful flowers in 2027

Some of the 18 entries for Class 13: Narcissus 'Pipit' CABAHS Spring Show 2025 — Sow sweetpeas and plant *Narcissus* bulbs for beautiful flowers in 2027

1. You can sow some sweetpeas now for an early start next year. Sow in root trainers or sow five seeds to a 3″ (9cm) pot and keep in warmth until germinated, then keep in an unheated greenhouse, coldframe or cool room until spring. Sweetpeas are pretty hardy. A sheltered corner of the garden may work too.

2. Plant Narcissus and daffodils now so they have a chance to make good roots for a spring flowering. If planting in soil plant as deeply as you can at about three times their depth.

10 Things for December 2025

December is a month when the garden often takes a back seat, and when Pat deserves a break from helping you all with your garden jobs, so the CABAHS Committee have come up with a list of 10 Things that they are doing this month in, from, or for their gardens.

Pat’s Jobs for January 2025

1. Prune Wisteria this month and next by taking all side shoots back to 2 or 3 buds. Very old plants may need severe pruning to show off the flowers.

2. Start pruning roses in earnest although some are still unbelievably flowering. Remove any foliage with blackspot and don’t compost. Old roses respond well to hard pruning so don’t be afraid, removing all dead and dying wood and cutting stems back to above a bud.

3. I had to remove dead Clematis shoots from a Daphne Jacqueline Postill and in doing so pulled off some of the flowers so take care and do it soon if you can. But leave the main prune until next month.

Pat’s 10 Jobs for February…

1. Prune Group 3 clematis (late flowering viticella types) now by cutting all stems back just above a leaf node starting from the ground up. Don’t be timid as they respond well. Then feed around the plant base with an organic feed making sure to avoid emerging shoots and mulch with compost.

2. If you have some, mulch your beds with homemade compost or leafmould. If you don’t have enough just mulch around your favourite plants.
