Pat’s top ten jobs to do in every month of the year.
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.
1. You can start planting tulips now, either in pots or in the ground. The deeper they are planted in the ground the more chance there is of them reappearing next year – but do protect them well from squirrels who love to eat them.
2. It’s not too late to plant Narcissus and other bulbs like Allium, but again as deep as you can if planting in the ground as squirrels do love to lunch on Allium.
1. Salvias are flowering their hearts out now but make sure you have some cuttings on stand by to cover any winter losses. And remember that quite a few are tender and will need winter protection in the colder months.
2. Last year I dug up my Dahlia tubers and potted them up once they had died down but lost quite a few despite keeping them frost free. So this time I will try leaving some in the ground and giving them a thick mulch. Of course, the problem then is trying to protect the new growth in spring from slugs and snails, so they’ll need keeping an eye on.
1. Well at last the rain has arrived and is ready to drown all our plants! You may need to empty those saucers you put under pots for some of your more tender plants before they drown or rot…
2. This month and next is a good time to cut down and split many perennials ready for our sale at the Horn Fair on 19 October which soon comes round. I split sedum and Hesperantha the other day. I needed two forks back to back but made about fifteen plants! Check which plants are suitable for splitting in Autumn as some are better done in Spring.
3. Increase your supply of Pelargoniums by taking cuttings now below a leaf node. It also provides insurance for next year. We always love unusual varieties for the sales table if you can spare them.
1. Time to trim back lavender hard if it has finished flowering, but try not to cut into the old wood. If you’re lucky you may get a few late flowers.
2. And time to give that Wisteria and Campsis a hack back by removing all the whippy growth and tidying up for the autumn.
3. Azaleas. Camellias and Rhododendrons are making their flowers for next year and need regular water at their roots or they’ll drop their buds and have no spring blooms.

2. Stake Dahlias before they get too tall and straggly or the stems may snap. Keep well watered in this dry weather.
3. To conserve water and before we get a hosepipe ban, just water around the roots of plants and mulch them if you can. Some are really suffering at the moment. So why not start sowing seeds of Eryngium giganteum ‘Miss Wilmott’s Ghost’ for a drought proof plant for next year? Loved by pollinators too.
1. Plant out Dahlias in a sunny spot in fertile soil adding some compost to the planting hole. I have to surround mine with Strulch on my allotment to protect them from the hundreds of slugs and snails lurking all around.
2. Take softwood cuttings now of Anthemis, Salvia, Verbena, Penstemon and Fuchsia. Cut below a leaf node and dibble around the edge of a pot. Salvias will also grow fine roots in water to give them a head start.
3. Look out for hellebore seedlings around the base of your favourite plant. The resulting plants may not resemble the parent but they could be even better.
1. Border irises are really doing their thing now and the show can be brief but make sure to keep the soil around their roots free of weeds so their rhizomes can bake a bit in the sun.
2. Time to Chelsea chop your tall perennials to stop them flopping later or to extend flowering. Good candidates are Phlox, Penstemon, Helianthus, Sedum/Hylotelephium – and I include vigorous Clematis too. You can either do the whole plant at once or just some stems to extend flowering, although it may result in smaller flowers.
3. Deadhead displays of pot plants like Violas to keep them flowering and stop them going to seed. Remember to give them a feed to keep the display going.
1. Pinch out sweet pea plants above the third leaf to make bushier plants and then, as the shoots grow, pinch out side shoots in the same way.
2. Sow hardy annuals now like Nigella, opium poppies and poached egg plants in any bit of empty ground you may have and mark them so you don’t forget where they are. Many of these are excellent for pollinators.
3. Prune hardy Fuchsias now to stimulate growth by cutting back to just above a healthy bud which will prevent them from getting too woody.
4. Check Dahlia tubers for any growth and make sure they’re getting enough light by turning them round regularly towards the light.

2. Now is the time I start sowing sweetpeas: five seeds to a 3 inch pot and keep on a light windowsill or greenhouse until they germinate. You can try sowing directly into the soil which I think works well for some.
