The Store now opens on a Saturday as well!

Through March and April The Store will open on Saturdays 9am-11am as well as on Sundays 10am-12noon.

Stocking seeds for planting now, weed suppressant fabric, and fertilisers sold loose – start the growing year with everything you need.

  • 1m x 10m rolls of Weed Suppressant at £7.50 per roll (1m x 10m). This has a weight of 100g per square metre which makes this strong enough to act as a good ground cover that will last for several years.
  • Growmore (£1.00 per kilo) is a popular non-organic fertiliser.  Apply every 4-6 weeks throughout the growing season from February to the end of October. Use as a top dressing, or as a base dressing, working it into the soil. During dry weather water before and after application.

  • Fish, Blood and Bone (£1.00 per kilo). Apply as a top dressing to the soil surface and  fork in well.
  • Seaweed Meal (£2.00 per kilo). Sprinkle onto you beds before planting or when plants need a boost. Add a few handfuls to your compost heap to add minerals and boost microorganisms.  You can also add a handful to potting soil before planting seeds or when potting on.
  • Chicken Manure Pellets (£1.00 per kilo or £6.00 for an 8 kilo bucket). Apply in Spring as a base fertiliser when preparing your beds for planting. Apply an additional feed 3-4 weeks after planting.
  • Onion Fertiliser (£1.50 per kilo). Apply to your onions 3 weeks after planting and then continue with applications every 3-4 weeks.
  • Lime (£0.50 per kilo). Apply 4-6 weeks in Spring before planting brassicas.

All about the RGS Shredder – March 18th 11.30am.

Demonstration of the RGS Shredder
Sunday 18 March 11.30am at the STORE
You may know that there is a large electrical SHREDDER on site 2 (near the Store) that has been out of order for a while. However it has recently been serviced by one of our plot holders, John Ireland, and is ready for use.

John has agreed to show plot holders how to use the shredder properly to prevent the problems that plagued it in the past. Only plot holders who have had this explained to them will be allowed to use the shredder.

If you are unable to come along on Sunday 18 March there will be further opportunities available later. Please let us know if you would be interested.
Shredded waste material makes wonderful compost!

March jobs on your allotment

March primulas

  • Continue soil preparation by hoeing to suppress early weeds and cover with black landscape fabric/ weed suppressant or a thick layer of composted stable manure to warm the soil. Top- dress overwintering vegetables with a general fertilizer.
  • Apply a general fertilizer to all areas required for early crops.
  • To lessen the impact of brassica club root, raise the soil pH by adding lime to brassica beds. Some club root resistant varieties are available in store, g. Brussels sprouts Crispus, Cabbage Kilaton.
  • Sow outdoors early cultivars of beetroot, broad beans, peas, early cultivars of lettuce, radish, early spinach, parsnips and turnips. Seeds available in store.
  • Towards the end of the month early varieties of carrot can be sown. Sow indoors or in the greenhouse Brussels sprouts, cabbage, celery, celeriac, early leeks and tomatoes, cucumbers, courgettes, peppers and chillies. Seeds available in store.
  • Start herbs from seed. Sow dill, fennel, parsley and sorrel in plots to transplant later. Herb seeds available in store.
  • Watch out for signs of damping off in seedlings and be careful not to overwater.
  • Prune blueberries.
  • Direct plant shallots and onion sets.
  • By the end of March, if the weather is warming, plant first early potatoes when the shoots are 2cms long
  • Plant asparagus crowns.
  • Prepare trenches for runner beans with well-rotted manure and shredded paper at the base.
  • Clean greenhouse panes to maximise light levels.
  • Children can sow Candytuft, available in store.

February jobs on your allotment

  • Prepare for early vegetable crops by warming soil before sowing, covering seedbeds with polythene or cloches.
  • Keep off wet soils to avoid compaction. Use long boards as walkways, to spread your weight.
  • If the soil isn’t too wet, start to dig in overwintered green manures such as grazing rye and winter tares, as the frost should have killed them off.
  • Continue to tidy up and re-cut grass path edges where the grass has encroached on your plot.
  • Give your compost heap a ‘spring turn’ this month. Turning will aerate and stimulate the heap. If it’s too dry, continue adding wet kitchen waste, and water it occasionally. If too wet, add more carbon-rich stuff such as twigs, crumpled cardboard and paper waste, to open up and aerate the heap. Continue to add layers of uncomposted stable manure to your heap.
  • Empty compost heaps when ready and spread the well-rotted dark crumbly compost on beds prior to sowing or use as seed compost.
  • Chit potato tubers in a light, cool, frost- free place.
  • Clean pots and trays by scrubbing in hot, soapy water before starting to sow new seeds. Pests and diseases can overwinter in old potting compost, surviving to damage newly emerging seedlings.
  • Sow sweet peas in deep pots or Root-trainers in a cold frame, greenhouse or windowsill. (A wide range of sweet peas – single varieties such as King’s High Scent and Midnight as well as mixes e.g. Mammoth mixed and Incense are all available in store. Root trainers are available in store as well as free pots in the pot box next to the store.)
  • Pot on and pinch out autumn-sown sweet peas to encourage side-shoots to form.
  • Sow (Check out the range of varieties available in store such as Ildi, Megabyte F1, Gigantomo, Fandango,and Akron).
  • Sow sweet and chilli peppers from mid- February in a heated propagator or sunny windowsill. Chillies can be slow to germinate. (Check out the varieties available in store such as Long Red Marconi, Trinidad Perfume.)
  • Sow aubergines in a heated propagator or sunny windowsill. (Check out the varieties in store such as Black Beauty and Long Purple as well as the patio varieties Jackpot and Pinstripe.)
  • Sow celeriac in a heated propagator or sunny windowsill. (Variety, Prinz is available in store.)
  • Sow broad beans outside. (Check out the varieties in store such as Karmazyn, de Monica, Masterpiece Green Longpod and The Sutton.)
  • Sow cabbage. Check sowing advice on packets for different varieties. (Cabbage varieties available in store are Greyhound and Hispi.)
  • Sow peas outdoors. (Variety, Early Onward, is available in store.)
  • Sow onions and early leeks in the greenhouse or under cover. (Varieties, Blue Solaise, Below Zero F1 and Giant Winter are available in store.)
  • Sow early lettuce and keep in cold frame or greenhouse for earlier harvest. (Varieties Oakleaf Navara, Salad Bowl and Little Gem Cos are all available in store.)
  • Sow hardy annuals for companion planting such as Calendula and Tagetes indoors for earlier blooms.

  • Prune autumn raspberries, cutting all canes down to the ground.
  • If summer-fruiting raspberries have grown above their supports, cut back to one or two buds above the top wire.
  • After pruning, apply a general-purpose fertilizer to tree, bush and cane fruit and mulch with well-rotted manure or garden compost. (all available in Store)
  • Top-dress all tree and soft fruit with sulphate of potash. (available in Store)
  • Spray dormant fruit trees and bushes with plant oil-based winter tree wash (available In Store) to kill overwintering eggs of aphid pests.
  • Apply 2” layer of well-rotted garden manure or garden compost around perennial crops such as Jerusalem artichokes or rhubarb. (Country Natural available in Store)
  • Start pruning bush roses at the end of the month.
  • Fruit bushes can still be planted now.
  • Force rhubarb for sweeter, earlier stems by covering crowns with straw and then a container to exclude light.
  • To reduce club root on brassicas, apply lime to soil at 270g per sq m, 8oz per sq yd. (lime available in Store)
  • Prepare a new asparagus bed by digging in well-rotted manure and order asparagus crowns.
  • Apply general fertilizers such as Growmore, (inorganic) or fish, blood and bone or seaweed, organic. (all available in Store)

Incredible Edible Seed Swap at the Garden Museum 27th Jan
