How do I con­trol ram­pant rhubarb?

Pam Corbin, Le­ices­ter In a fer­tile, moist soil rhubarb can be quite a thug, which is why it’s of­ten rel­e­gated to a se­cluded cor­ner. I find the sim­plest op­tion is to al­most de­fo­li­ate clumps in May and June when pulling the stalks. De­spite what’s of­ten said, sur­plus leaves and stalks can be safely con­signed to the com­post heap. The other op­tion is to di­vide ev­ery three years rather than the typ­i­cal five year in­ter­val.

Where can I get mangetout ‘Sweet Hori­zon’ seeds?

Garry O’Sullivan, Hilling­don, Mid­dle­sex This is a great mangetout, ideal for suc­ces­sional sow­ing from March into June. It’s mildew re­sis­tant, cop­ing well with warmer sum­mer weather. At just 90cm (3ft) in height, it’s also suit­able for con­tainer grow­ing where space is limited. When in flower, wa­ter well to max­imise pick­ings. It’s widely avail­able in good gar­den cen­tres. Al­ter­na­tively, for mail or­der try Thomp­son & Mor­gan (tel: 0844 573 1818) or Sim­ply Seed (tel: 01157 270606).

Do you need to pinch back flower seedlings?

Mick Fi­doe, by email This de­pends very much on how they’ve grown. If sown in good light, pricked out and po ed on with plenty of space be­tween the seedlings, they may nat­u­rally de­velop as nice bushy plants. In gen­eral, how­ever, most small flower plants will ben­e­fit from pinch­ing out the cen­tral grow­ing point to make them bush out. While slightly de­lay­ing flow­er­ing, it will also tend to in­crease the to­tal amount of flow­ers.
