Fact Sheet

Q 鈥� I find radishes hard to grow well 鈥� what am I doing wrong?

听

Bob 鈥� I鈥檇 let radishes bolt 鈥� those little seed pods before the seeds form are delicious.听 German variety: 鈥楳unchen Bier鈥�.听 I think you鈥檙e sowing them too thick.听 Thin them out early on so they鈥檙e at least an inch (2.5cm) apart.

听

Pippa 鈥� Quickest way to get something to run to seed is fluctuating or inadequate moisture levels in the soil.听 Try growing Mooli.

听

Matt 鈥� Grow it in a container of multi-purpose compost, keep it moist, and harvest when they鈥檙e quite small.

听

Q 鈥� I have a 25-year old Clematis.听 It is a tangled mess.听 How can I rejuvenate it?

听

Bob 鈥� I鈥檇 guess this is a Montana.听 Hack it back as much as you want.

听

Matt 鈥� Cut it back in stages.听 If there are six major stems then do two each year and prune straight after flowering.听

听

Q 鈥� How can you make courgettes climb?听 I grew 鈥楽hooting Star鈥� this year but they show no inclination to climb.

听

Pippa 鈥� You can鈥檛; they don鈥檛!听 Try climbing squash instead, they work much better, something like Butternut or 鈥楾urk鈥檚 Turban鈥�

听

Bob 鈥� Pumpkins climb.听 Loofahs (another gourd) - I鈥檝e seen them climb 30ft.听

听

Q 鈥� I planted chitted parsnip seeds in June but have found that the plants have stunted roots 鈥� what鈥檚 wrong?

听

Bob 鈥� I suspect the bed is too loose.听 Make holes and fill with sand and sow in the top of that.听 The seed will then make one root to search for water/nutrients.

听

Pippa 鈥� High nitrogen levels would be my suspicion

听

Q 鈥� What is the best way to deal with rust on Pelargoniums?

听

Pippa 鈥� The rust loves moist, stagnant air.听 So keep air dry and well circulated.听 For already affected plants I would pinch out the affected leaves.听 Only ever water at the base.

听

Q 鈥� My daughter is getting married on June 24 next year.听 I want to grow white flowers for decoration.听 Suggestions?

听

Matt 鈥� Anything with the name 鈥楢lba鈥� in it really!听 White sweet peas, White Cosmos, grasses.听

Pippa 鈥� Successional sowing is important to raise the chance you鈥檒l have flowers on that specific day.听 White Candytufts would be nice.听 Gypsophila maybe.听 White Cornflowers.听

听

Bob 鈥� Iceberg roses

听

Q 鈥� I have a twenty-year-old Crabapple.听 It recent years I have tried grafting scions onto other trees but none seem to take. What鈥檚 going wrong?

听

Bob 鈥� You need to do it in spring as the sap rises and use pieces of wood cut off in the autumn (so they鈥檙e full of sugars).听 鈥楢pproach grafts鈥� are the easiest.听 Try making bigger grafts.

听

Matt 鈥� Try chip budding

听

Q 鈥� How can I grow asparagus from seed?

听

Bob 鈥� It鈥檚 easy but takes a couple of years.听 You only get seeds from female asparagus plants.听

听

Matt 鈥� Put them on raised beds
