Home­grown toma­toes worth the ef­fort

Wairarapa News - - WHAT’S ON - LYNDA HAL­LI­NAN


Grow­ing your own toma­toes from seed is eco­nom­i­cal if you want to grow many dif­fer­ent va­ri­eties, or if you’ve saved your seed from last year’s fruit. They do, how­ever, need a lit­tle mol­ly­cod­dling. Sow tomato seeds in plas­tic seed trays or small in­di­vid­ual pots filled with ster­ile seed-rais­ing mix. Don’t sow too deep – a light (1-2mm) sprin­kle of seed-rais­ing over the top is suf­fi­cient. En­sure the mix is moist, but not wa­ter­logged, and cover with a plas­tic sheet or bag. This traps the hu­mid­ity to speed up sprout­ing. Place the trays or pots in a warm spot, such as in­side a hot wa­ter cup­board. As soon as you see signs of ger­mi­na­tion, re­move the plas­tic and move the pots into a brightly lit lo­ca­tion in­doors, such as a sunny win­dowsill. They need as much nat­u­ral light as pos­si­ble or they’ll grow tall and spindly (leggy). Once they are 3-5cm tall, move them un­der a cloche or to a tun­nel­house for bet­ter light. The seedlings will need re­pot­ting into larger pots of pot­ting mix after a month. They will be ready to trans­plant at Labour Week­end.


The first straw­ber­ries will be ripe in a few weeks, so spend some time this week­end tidy­ing up es­tab­lished straw­berry beds. Weed (care­fully) around your plants. Do this with a hand-held trowel or fork rather than a push hoe or spade, as straw­ber­ries have wide spread­ing roots that are eas­ily da­m­aged when you’re yank­ing out com­pet­ing weeds. Once the weeds are all cleared, lightly wa­ter in fer­tiliser. You can use any gen­eral pur­pose NPK fer­tiliser, as straw­ber­ries are vig­or­ous grow­ers with a gen­eral hunger for ni­tro­gen as well as the potas­sium in a spe­cial­ist fruit fer­tiliser such as Dal­tons Straw­berry Fert or a tomato fer­tiliser. The fi­nal step is to lay mulch or straw over the bare soil around your plants to sup­press weed growth and keep the de­vel­op­ing fruit clear of the soil. Later, when the fruit is ripe, it will be less sus­cep­ti­ble to rot­ting on the un­der­sides or get­ting grey mould if it isn’t sit­ting on damp spring soil. Get your bird cov­ers sorted now too. Plas­tic netting does the trick.


Win­ter-dor­mant peren­nial crops of as­para­gus and rhubarb may not be show­ing any signs of life yet, but they will at least be think­ing about it! (Even though the first lo­cally grown as­para­gus spears are avail­able in shops al­ready, my first spears don’t emerge un­til early Oc­to­ber.) Re­move any weed growth around both of these crops and mulch them well to stop an­other rash of weed seeds ger­mi­nat­ing in spring. No weeds also means no place for slugs and snails to hide, while mulching also helps in­su­late the soil, warm­ing it up just a notch.


Although it’s of­fi­cially spring, we have a wee way to go yet be­fore our vege gar­dens are back into harvest mode. Bridge the gap be­tween the last win­ter bras­si­cas and the first sum­mer salad greens with spinach, silverbeet or colour­ful Swiss chard. Plant a row of spinach (or the mild ‘Per­pet­ual’ va­ri­ety of silverbeet) un­der a cloche or plas­tic-cov­ered grow tun­nel to cut the grow­ing time

Tahi­tian limes will be turn­ing yel­low by now, a sign they are fully ripe and will soon drop off the branch. If you have more than you need, freeze whole fruit in freezer-safe plas­tic bags. When thawed, there’s no no­tice­able drop in qual­ity of ei­ther the zest or the juice. Limes are cheap and plen­ti­ful right now so put a few on ice for sum­mer; in the lead up to Christ­mas, they cost as much as $39.99/kg.
