What do I do with my clematis over winter?

Posted: 12/10/2014 at 13:00

Clematis are hungry an dthirsty plants so the first thing to do is to plant it in the ground or in a much bigger pot - 60cms minimum.   The white mould is a sign of stress from lack of moisture and probably food as it will have exhausted the supplies in that compost.

Plant it 3 or 4 inches deeper than it is now as this will encourage new shoots to form and provide extra flowers next year.  If in a pot, give it the best compost you can afford - John Innes no 3 and give it a mulch of pebbles, chipped bark or expanded clay pellets to retain moisture and stop weeds growing.   Give it regular liquid feeds of rose or tomato fertiliser from March to July or August.

If in the  ground, mix some well rotted manure or garden compost in the hole to provide moisture retention and food.   Scatter wildlife friendly slug pellets around it every week fromm Valentine's Day as they love the new shoots.  Give it a handful of slow releas clematis food in spring and occasional tonics of liquid rose or tomato food.

Prune your clematis hard back to about 9 " or the lowest pair of buds on each stem next spring in Feb or March depending on how cold you are.  Do not prune during a  frosty period.

Give it a decent sized obelisk or trellis to grow up as it will get much bigger next year.

Are all Cornishmen narcissists or do some just content themselves with growing beautiful daffs and other stuff?

Pruning climbing roses and clematis

Posted: 12/10/2014 at 11:41

Both these clematis flower in spring on old wood so wait until they have finished flowering and then prne them as hard as you like.  

Give them a generous feed of slow release clematis food once done and an instant tonic of liquid tomato or rose food and they shoud produce plenty of healthy new growth over the summer which you need to tie in and train before it gets into a complete tangle.   Flowers will then come again the following spring.

Climbing roses usually flower best on new season's growth so, in early spring when no frost is forecast for a few days, prune out dead, broken and spindly stems.   Tie in, as horizontally as possible, the remaining strong stems and remove any which cross or grow out and away from their supports.  This should leave you with a strong framework of stems with flowering spurs that will gorw and produce a sho in summer.

Feed generously with rose fetiliser and liquid tomato or rose food.    Keep them dead headed through the season and they should flower all summer.   Did you find this page on the RHS site?

Can't tell you till I buy some more next spring but they've done better on it than just with my usual pelleted chicken manure.

Clematis pruning

YOu are right.  There are differe pruning rules for the 3 main clematis groups but as a general rule, any that flower before the end of June get a light pruneimmediately after flowering and those which flower later get pruned hard back in Feb or March dependig on whether it still freezing.

I suggest you prune the late purple one in early spring then give it a good handful of proprietary clematis food and another mulch.   This will encourage it t prune new shoots which will flower later next summer.  An occasional liquid feed of tomato or rose food will hep too.

For the others, wait and see when they flower.   If they flower before the end of April they are likely to be group 1s which only get pruned to keep them to size and encourage new flowers lower down.    Those which flower in May and June just need a light trim to remove dead heads after flowering.   Given a good feed as above they will probably produce another flush of flowers in late summer.

All clematis are hungry, thirsty plants so feed in spring with a slow release food and mulch and then oaccasionally give a liquid feed as above.  This works on roses too.

Honeysuckle don't need so much food and just need pruning to keep them to size.

I guess it depends on the subject of the forum.  If it's foody or sewy or some other activity where recommendations for suppliers in your locality would be perfecty reasonable but some people are rightly wary of giving personal info away and protect their privacy.

Not my favourite plants either but easy for hanging baskets and tubs in hot spots and when I find one with good strong colour I try to keep it.   Not interested in growing fancies from seed so have to rely on local suppliers and they can be a bit bog standard.

Can someone tell me when's it's best to hard prune a lilac?

Posted: 10/10/2014 at 10:39

Pruning to shape is done immediately after flowering as spring flowering plants do it on last year's wood an dthis gives them time to grow new stems and flower buds.

If you are doing a drastic prune and can't wait till they've flowered again then you could do it now, or as soon as the leaves have fallen and the plant is dormant, but you will have no flowers next spring.

It is so warm here still that I have pelargonium still in full flower outside.  Normally by now we've had a frost of a few degrees.

I'm keeping an eye on temps forecasts so I can bring them in in good time and will be taking cuttings of the more interesting flowered ones as insurance this weekend.
