10 jobs for the month – Page 3 – Charlton and Blackheath Amateur Horticultural Society

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 Jobs for November 2024

1. Check for blackspot on roses and make sure to remove the leaves by checking the bush itself and below it. But don’t add to the compost heap.

2. If you have to, this is the best time to move trees and shrubs, but have your planting hole ready, and dig up with all the root ball and replant quickly, watering well until settled.

3. Plant your tulips and hyacinths now. either in the ground or in pots – but protect from squirrels.

4. If you sowed sweet peas last month. harden them off now and it’s still not too late to get some going for an early crop.

Pat’s Jobs for October 2024

1. Watch out for Cabbage White caterpillar on your Nasturtium: at our allotments they appear to be the new delicacy which they are devastating and they look like the only butterflies that are thriving.

2. Make sure to plant lots of butterfly-friendly plants next year like Sweet Rocket, Scabious, Honesty and others. The butterfly count showed that butterfly numbers are very much down this year and we desperately need them. Please ask me for Honesty seeds if you want some.

Pat’s Jobs for September 2024

1. Start ordering your bulbs now as all the bulb catalogues are arriving – though prices don’t stop going up!

2. Start planting bulbs when they arrive but save your tulips until later as they are prone to virus and rotting, and to theft by squirrels.

3. Divide large established clumps of perennials by cutting back first, then splitting either by hand or with two forks back to back. Delay if soil is heavy or too wet.

4. Replace tired summer bedding in pots and replant for winter and replenish with fresh compost.

Pat’s Jobs for August 2024

1. It is especially important to keep Camellias and Rhododendrons damp at the roots this month as this is the time that the buds form for next Spring. Water well and mulch if you can.

2. Take Aeonium cuttings now by severing leggy leaf stems a couple of inches below a cluster. Leave the stem end to callous over, then push into gritty compost and keep in a shady spot until roots start to form.

Pat’s Jobs for July

1. Top of the list for July is pruning wisteria, taking back that whippy growth to 2 to 3 buds from the main stems.

2. Sweetpeas should be flowering by now so make sure to keep cutting the blooms and give them a feed and plenty of water. They cease flowering quickly if not picked twice a week.

3. Deadhead all your perennials and annuals regularly unless you want them to set seed for next years sowing.

Pat’s Jobs for June

What a strange spring this has been as everything has grown so tall ….but then some things especially vegetables have hardly grown at all and are struggling as there has been little warmth.

Cephalaria a foot taller than usual — Giant Foxglove – 8 foot tall

Anyway we soldier on….

1. Divide spring flowering bulbs as soon as foliage fades. My own stock has diminished and badly need splitting.

2. Prune ornamental cherries when flowering has finished making as few cuts as possible as they have difficulty healing.

3. Tie in shoots on sweetpeas which are finally growing and revelling in the cool conditions.

4. Cut early flowering hardy geraniums to the ground when they finish as they have a tendency to seed everywhere…unless you want them to of course.

Pat’s Jobs for May

1. It’s a good time to take softwood cuttings of both tender and hardy perennials such as pelargoniums, anthemis and penstemons. Place in a shady spot until roots begin to form.

2. Put plant supports in place to stop things flopping and make them yourself from shrubby prunings or just push prunings in the soil around the plant.

3. I’ve Chelsea chopped my phlox today and also done a few clematis as they are far too tall and leggy after all the rain we’ve had.

Pat’s Jobs for April

1. Prune hardy fuchsias now both in pots and in the ground to promote new growth and to prevent the plants from becoming too woody.

2. Plant out pot grown sweet peas now making sure to pinch out the shoots to promote bushy plants. You can also sow directly in the ground now if you didn’t sow earlier but watch out for slugs munching new seedlings.

3. Someone said the other day that they hadn’t cut back their clematis but I don’t think its too late as the growth on them is phenomenal. It just means they will flower a bit later but then that extends the season.

Pat’s Jobs for March

1. I sowed my sweet peas early in the month five seeds to a 3 inch pot and then placed them on a light window sill or greenhouse if you have one. They don’t need bottom heat and I don’t soak or nick the seeds but of course you can if you wish. Keep turning the pots so they don’t all lean towards the light.

2. Remove browning blooms from camellias to keep the display going especially the white ones which never seem to drop their spent blooms. I just wish I had room for more as they’re such a cheerful sight.
