GQT at Â鶹ԼÅÄ: Trees with Knees

Gardening programme featuring a group of green-fingered experts, chaired by Kathy Clugston.

Gardening programme featuring a group of green-fingered experts, chaired by Kathy Clugston. Matthew Wilson, Bunny Guinness, and Bob Flowerdew dispense the horticultural counsel.

This week, the panellists tell us what to look for when purchasing a new pair of secateurs. They also talk through how best to use your garden compost, and share planting ideas for a protective hedge around a listener's coastal allotment.

We resume our great trees of GQT features with Anne Swithinbank, who this week delights us with a tree that has knobbly knees - Taxodium distichum.

Meanwhile, Cherry Carmen shares her favourite plants for winter colour to entice us outside on those short winter days.

Q – I have a gooseberry bush and a blackcurrant bush growing in close proximity. I’ve noticed gooseberry branches growing from blackcurrant stems. Is this normal?

Q – I have an Aeonium Schwarzkopf. This year it has become mottled and has lost its purple colour. Any idea why, and what I can do about it?

(6 minutes 10 seconds)

Ìý

Q – I have 11 compost heaps as I recycle everything. I have a lot of perennials, fruit and veg, as well as doing a lot of propagating. I use the compost for mulch, but can I also use it as a potting compost for containers as well as for sowing seeds?

(8 minutes 55 seconds)

Ìý

Feature – Anne Swithinbank talks us through her favourite tree Taxodium distichum, the Swamp Cypress. Have you ever seen a tree with knees?

(13 minutes 50 seconds)

Ìý

Q – I received a lemon tree for my birthday 2 years ago. It blossoms in the winter but never fruits. It now has yellow blotches on the leaves, woodlice in the roots and has recently developed a crusty speckled bark. How can I revive it?

(20 minutes 10 seconds)

Ìý

Q – Can the panel suggest an evergreen hedge to protect my 25 x 9m (82 x 29 feet) allotment plot from coastal gales throughout the year. I would like a hedge that doesn’t compete with the crops for nutrients, is easy to get cuttings from, and is low maintenance.

Q – Last year we planted tomatoes in our greenhouse. While we were away the whole greenhouse was overwatered by the automatic system, which caused tomato blight. What should we do with the soil? Should we quarantine it, or just scrape off the top 10cm, top up with fresh compost and plant as usual?

Q – We moved to a new house last year, and the previous owner had planted a Magnolia which needed pruning. It bloomed well, but by the summer the leaves look sickly and yellow. I think it was caused by our alkaline soil. Should I add sequestrene, or is there another method of helping it? Could the panel suggest a replacement plant if I should just remove it?
