Plant List

Introduction (1 minute 20)

Ìý

Wilmott’s whitebeam (Sorbus wilmottiana)

Ìý

Q – I have got a friend who has an 8-year-old tree which has grown from the off-spring of Anne Frank’s Horse Chestnut and I was wondering how to propagate it? The soil is well-drained sandy loam. (3 minutes 15 seconds)

Q – Out of pure curiosity my partner has been germinating seeds from fruit he has brought at the supermarket this year with some success. We have plums and apples at 4 foot (1.2m) already, with apricot, passionfruit, lychee, and orange plants not far behind. As they grow what is the best way to keep these plants healthy in pots which are light enough to move to a new house with? (8 minutes 45 seconds)

Ìý

Anne – Loquat


Matthew – Avocados

Ìý

Q – Two years ago I planted lots of Alpine strawberries (Fragaria vesca). They were great to start with but now they swamp and strangle most other plants and even with regular pulling out they come back. How do I get rid of them and what should I plant to smother them?Ìý (11 minutes 15 seconds)

Q – I really want to get some houseplants for my kitchen, ideally ones which will dangle from the top of my dresser, but the room is north-facing and quite shady. What would be the best houseplants? (15 minutes)

Ìý

Q – My autistic son is obsessed with the video game Plants vs Zombies, where many of the characters are carnivorous plants. Over the years we have amassed a collection, watered exclusively with rainwater and live outside from Easter to autumn, and happily over-winter in my sons very cool bay window. They have been re-potted as they have grown and flowered a few times. The Sundew (Drosera capensis) has really thrived going from one tiny plant to at least 7. When I move them to a much bigger pot this autumn should I trim all the dead growth away and should I repot them so that the soil level buries these so it lies at the green growth point of the plants?Ìý (20 minutes 5 seconds)

Q – I work at Chard Hospital in Somerset, the entrance to which has a lovely copse of trees. I am interested in planting some Anemone nemorosa (Wood anemone) or native bluebells among these.

Q – My husband recently dug a pond in a part of the garden previously known as the vegetable plot. We have edged the pond with slate slabs but for some reason we have much more slate than was needed, so the slabbing has now spread in a patchwork around the remaining area. We have planted ferns, hostas, hellebore, and a few other things around the pond. The patch is 5mx4m (16.4 foot x 13.1foot) and the pond is 2mx 1.5 m (6.5foot x 4.9 foot) but it is quite sheltered, with trees on 3 sides and a 4 foot hedge (1.2m) on the east side. We would like to have wildlife friendly plants between the slabs and along the perimeter preferably with a few different heights.Ìý (27 minutes 56 seconds)

Q – I have a Passiflora antiquiensis (red banana passionfruit) in a pot which hasn’t flowered since the first year I got it about 6 years ago. It spends the winter in a cool part of the house and goes out for the summer. It’s about 2-foot-high (0.6m), straggly, and in a 12-inch pot. I admit I probably haven’t fed it much. How can I encourage it to flower please? (34 minutes 4 seconds)
