Can you tell me what this is please? In the Isabella plantation in Richmond Park
Hi! I was wondering if anybody could tell me the scientific name for this plant please. Never actually known the name of it, even though it's very common.
Hello, I'm wondering if anyone can recommend any supporting text books to go with the RHS level 2 course? Thanks
Hi there. Will there be an update soon about the Feb Rhs exams in February?
Hey guys! What is going on with this cherry tree?
Does anybody know what type of h**e this is please, trying to work out plant placement/soil type
Hi. I wonder if you can help me with a rose challenge. The Roses to the left of this picture are about 12ft already, seem to have the form of a ramble, but with nowhere to go, there is nothing behind them to grow into.. they just wave frantically in the sky, dwarfing the (quite tall already) forsythia. They do Not show signs of flower budding the Owner does not know what or if they have every flowered. The stems are true and from the main plant, what can I do with them. I’d like to get them under control or something! Any suggestions please, thank you
I need some help, I planted this tree last spring. It had tons of growth at the top of the stem. Once the leaves fell off in the winter it stayed a bare stem. A couple of weeks ago I noticed new growth at the base. My question is do I cut the bare stem off or leave it? It is dead about 2/3 of the down. It’s a empress tree.
Anyone know what these are?
Anyone can tell me what’s this is thanks plant or food
Hi I have a tomtato growing by accident but don’t know how to look after it as I don’t really have green fingers
Is this a w**d or I need answers of what it is before I pull it out of my garden. It decided to grow up between my peppers

Tip of the Day is that the smell of autumn can be toffee. Cercidyphyllum japonicum, or the Katsura tree, is known for fantastic autumn colour - but the hot and dry spell with which September started has caused some leaves to fall early and without developing much colour. However a light breeze brings out the scent which gives it another common name - the toffee-apple tree. Crush the leaves in your hand and sniff the distinctive burnt sugar smell, toffee without calories.

Tip of the Day is to 'cure' onions and shallots for storage. Once you have lifted onions, the skins and foliage need to dry off completely to 'cure' the bulbs; the same thing applies to shallots (pictured here) and garlic. Space them out in trays, on racks or greenhouse staging until the outer skins are papery and the roots have shrivelled.

Tip of the Day is that planting in a copper preserving pan, and mulching with sharp grit, have preserved this specimen of lobelia from snail damage - however when it was placed any closer to nearby shrubs the snails climbed up and then managed to make their way across - abseiling? - so the pan has to sit in splendid isolation!

Plant of the Day is Ceanothus 'Gloire de Versailles'. Not all ceanothus are evergreen - there are some deciduous cultivars like 'Gloire de Versailles' with blue puffball flowers in late summer which are very attractive to bees. The deciduous forms can be pruned hard back in late winter to keep them in check - they flower on the new growth so will flower in the same year.

Tip of the Day is that Lobelia cardinalis is a snail magnet.One of the reasons for growing L. cardinalis as a marginal is that snails will travel from miles around to strip the soft red epidermis from the stem, leaving only the central tough core.

Plant of the Day is Lobelia cardinalis 'Queen Victoria'. This late-summer perennial has beetroot-coloured foliage and striking scarlet flowers; it's a stunning border plant but does best in moist conditions, or even grown as a marginal on the edge of a pond.

Tip of the Day is on pruning other tree fruit. You should now be finishing your pruning on the extension growth on trained forms of apple and pear - it is best done in August/September, because pruning too early just stimulates more extension growth, rather than promoting fruit buds.

Plant of the Day is Luma apiculata. Chilean myrtle is a slow growing evergreen shrub or small tree; the bark is grey to cinnamon brown, peeling as the tree grows. Small oval leaves are fragrant, with white puffball flowers in midsummer followed by berries attractive to birds.

Tip of the Day is that it's too late now to prune stone fruit. Fan-trained stone fruit like peaches, apricots, nectarines and plums should be pruned in late spring or early summer - leave it until next year if you haven't pruned yet, or you risk allowing fungal diseases like silverleaf to enter the pruning cuts.

11/09/2021

Plant of the Day is Hibiscus 'Oiseau Bleu'. This is better-known in translation as 'Blue Bird'; the large single flowers are strong violet-blue with a maroon centre. Hibiscus flower on this season's growth, so they can be hard-pruned like roses to produce lots of new buds.

Tip of the Day is to recognise, but not be put off by, potato scab. The rough warty skin typical of potato scab is caused by a disease which thrives in dry conditions and chalky (high pH) soil. Damage is generally superficial and potatoes can be peeled and eaten.

Plant of the Day is Hibiscus syriacus 'Hamabo'. Hibiscus are good shrubs for late summer colour on neutral and chalk soils, but they are slow to come into leaf and the early leaves tend to look surprisingly yellow, greening up later. 'Hamabo' is a cultivar with exceptionally large blush-pink flowers, with a conspicuous red blotch at the base of each petal. Deadheading will help to keep the shrub looking at its best.

Tip of the Day is not to delay with willowherb. It's often hard to keep on top of w**ding, but try to get to willowherb as soon as you see it flowering - once the w**ds set seed and you pull them, you will be scattering the tiny parachutes onto the wind and creating many more w**d problems for yourself.

Plant of the Day is Lysimachia clethroides. 'Gooseneck loosestrife' is a rather unappealing name for this unusual, vigorous and clump-forming member of the Lysimachia genus - simple spikes of white flowers like Veronica are held high over greyish-green leaves, but the flower heads bend at the neck as if they are always wilting.

Tip of the Day is to take fuchsia cuttings. Another plant that is propagated easily from softwood cuttings is the fuchsia; hardy fuchsias are just beginning to flower, and there are plenty of sideshoots to use. If you can find shoots with leaves in threes rather than pairs, these will make stronger plants

Plant of the Day is Lablab purpureus 'Ruby Moon'. Lablab or Dolichos is a short-lived twining climber which is grown here as a tender perennial; in late summer it produces sprays of purple pea flowers, slightly fragrant, followed by ornamental purple pods which are supposed to be edible.

Tip of the Day is to take softwood cuttings. After the first flush of flowers, penstemons will produce a lot of new shoots before the next flowering; you can use this material for softwood or tip cuttings, which will root quickly if you keep the cuttings humid.

Plant of the day is Hakonechloa macra 'Aureola'. The common name for this attractive ornamental grass is unfortunately Golden hakonechloa; it forms a striking cascade of narrow golden leaves striped with green, arching in mounds about 30cm high which can turn reddish in autumn.

Tip of the Day is to try to check runner beans every day ( in daylight!), because they grow very fast and the beans aren't easy to see under the leaves - it is important to pick even oversize bean pods which you don't want to eat as 'green beans' as the plants will carry on flowering and being productive as long as you carry on picking them. Only leave the pods to swell if you want to dry and eat beans towards the end of the season, or save your own seed for next year.

Plant of the Day is Epilobium canum. Formerly Zauschneria californica, this is a species of willowherb now placed in the evening primrose family. It is a wiry drought-tolerant sub-shrub, with greyish leaves and vivid scarlet-orange trumpet flowers, native to dry chaparral slopes of California and western North America.

Tip of the Day is another positive point about yellow raspberries - even when they decide to grow outside the fruit cage, the birds don't seem to go for them at all, so you get to enjoy more of them yourself.

Plant of the Day is Campsis radicans f. flava. The large trumpet flowers of this form are soft golden yellow, a much more subtle colour than the orange-red of the straight species. However it is just as vigorous so make sure you have plenty of space for it, a sheltered south or west facing wall or fence to get the best flowering.

Tip of the Day is that yellow raspberries have unexpected advantages. Quite suddenly in September the daylight starts to end earlier than you expect, and you can find yourself trying to do something at your 'usual' time but it is almost dark; 8.15 pm is now too late to pick red raspberries or beans, but an unexpected benefit of 'Autumn Gold' is that you can still see it in the the dusk!

Plant of the Day is Campsis radicans. The trumpet vine or trumpet creeper is native to the eastern United States - it is a vigorous, deciduous shrub which can climb to 10m using aerial roots to cling to warm, south-facing walls. It produces huge numbers of tendrils that grab onto every available surface, and eventually expand into heavy woody stems several centimetres thick. It is late into leaf in the spring, producing bright green pinnate leaves and in late summer showy orange-red trumpet-shaped flowers.

Tip of the Day is to pick peaches promptly. There is a very brief moment when home-grown peaches are ripe - they start to rot very fast, even when they survive insects and birds.The skin of Peregrine, a white-fleshed peach, is quite tough but the taste is superb. If you have a sunny wall or fence, or the side of a shed like this, think about whether you have space to fan-train a peach.

Plant of the Day is Kniphofia 'Nobilis'. Red hot pokers continue their display well into autumn; 'Nobilis' flowers into September, with fiery flowerheads on top of stems nearly 2m tall, then later Kniphofia rooperi will come into flower in October.
