Fact Sheet
Q 鈥� Why do the herbs that I buy from the supermarket not grow long term?
Christine 鈥� Often the plants are forced and pumped full of fertiliser to make them attractive to buy and this can鈥檛 last.听 You鈥檙e better growing your own from seed.
Bob 鈥� Because they鈥檝e been grown quickly they are often missing flavour too
Matthew 鈥� You could get some 9cm(3.5inch)/1l pots, fill them with compost, pop them on the windowsill and sow directly into those.听 Harvest at micro veg size and you鈥檒l get even more flavour because there鈥檚 less water in them.
Eric 鈥� Also, the plants are too crowded in supermarket pots so it鈥檚 often a good idea to split them up and repot them and they鈥檒l have a better chance of survival.
Q 鈥� What can I do to help my garlic?听 The leaves are yellowing and they鈥檙e looking a bit sad.
Bob 鈥� Garlic has to make big leaves and then the leaves make the bulbs swell.听 So you want lots of leaves for big bulbs.听 You could improve the drainage.听 I grow mine in buckets and keep them indoors through winter and then move them out in spring and this gives a longer growing season.听 Try putting open-topped cloches on them to keep them a bit warmer.听

Q 鈥� About 16 years ago, following the advice of Bunny Guinness, we created a wooden climbing frame for our young child that could be converted into a trellis for climbing plants later.听 Now that our child is preparing to go to university we are about to move the frame into its second life.听 What hardy, vigorous climbers can the panel recommend? It鈥檚 in a shady area.
Matthew 鈥� You鈥檙e going to have to improve the soil first and foremost.听 Then you could run some Ivy up it.听听听听听听听
Bob 鈥� Could you move it to a sunny position? That would make the climbers flower much better, though they will grow in shade. 听Try climbing roses 鈥� not ramblers, they will swamp it.听 There鈥檚 one 鈥� 鈥榋epherine Drouhin鈥� 鈥� that鈥檚 famous because it鈥檚 thornless which is nice.听 Then, Akebias are nice early flowerers.听 Jasmines too, Clematis montanas like the 鈥榃ilsonii鈥� would be great.听
Christine 鈥� Look at the early-flowering Clematis like macropetala and alpina.听 You could look at annual climbers like Sweet Peas, the 鈥楥hilean Glory鈥� vine, the 鈥楥up-and-Saucer鈥� vine, or 鈥楳orning Glory鈥�.听 But they would do better in the sun.

Q 鈥� I want to turn my small, concrete yard into a wildlife oasis.听 I want to grow a tree that鈥檚 beneficial for both birds and pollinators, what can you suggest to grow in a large pot?
Matthew 鈥� Crabapples 鈥� you can get a whole variety of sizes.听 I like 鈥楻ed Sentinel鈥� and Maylus sargentii which over a decade will only get to 1.6-1.7m (5.2-5.5ft) high and 1.8m across.听
Christine 鈥� Have a look at the smaller Sorbuses (the 鈥楳ountain Ashes鈥�) and their relatives like cashmiriana, vilmorinii, and 鈥楯oseph Rock鈥�.
Bob 鈥� I鈥檇 put a post in the middle of a big pot and grow a bramble
听
Q 鈥� I have a Cercidiphyllum japonicum 鈥楶endulum鈥� and every year it suffers scorch from late frost.听 Apparently spraying with cold water before the sun appears can stop this.听 Is this true or, if not, could you suggest other methods please?
Matthew 鈥� This is a weeping type of Katsura with a very interesting scent.听 Scorch is caused by the defrosting, not the frost itself, so westward plants scorch less than the eastward ones because they warm up more slowly throughout the day.听
Bob 鈥� Easiest thing to do is cover it with something like a net curtain the night before.听 To spray with water, you鈥檇 need to be out at 5am every day!听 You could try putting a sprinkler on overnight to stop it frosting.
听
Q 鈥� I grow flowers for cutting but my Gladioli have been water damaged in recent years.听 As I planted well over 90 over a six-week period this was disappointing.听 What am I doing wrong or is the weather to blame?
Christine 鈥� Unless you鈥檙e going to put a physical cover over them I鈥檓 afraid heavy rain will damage Gladioli.听
Bob 鈥� You could try new varieties of gladioli called 鈥楪lamourglads鈥� and their not quite as big and because the patterns are more varied you don鈥檛 see the water damage as badly.
听
Q 鈥� We are planning a community garden.听 We want to plant something fun and unusual in the raised planters 鈥� ideas?听 The planters will be 2m x 1m (6.5ft x 3.2ft) and there will be three or four of them.
Christine 鈥� Mandrakes
Matthew 鈥� Long-term: plant Yew or Box that you can gradually train into topiary.听 Short-term: go crazy with Canners and lush Lilies and big blowsy Geraniums and Pelargoniums, half-hardy Salvias 鈥� things with lots of colour.
