Squash 'Kabocha Sun Spot' F1 - SeedsCucurbita maximaKabocha squash

Sow squash seed indoors from April to May for transplanting later on. Sow squash seeds on their sides in small 7.5cm (3") pots of seed compost at a depth of about 2cm (¾"). Place in a propagator or seal pots inside a plastic bag at a temperature of 20-25C (68-77F) until germination which takes 5-7 days. Do not exclude light, as this helps germination. Once germinated, grow squash on in cooler conditions until all risk of frost has passed and squash plants are large enough to be transplanted outdoors. Gradually acclimatise them to outdoor conditions over 7 - 10 days before planting squash outdoors in warm, well drained, humus rich soil in full sun,. Choose a spot that receives at least 6 hours of direct sun per day.

Alternatively direct sow squash seeds outdoors from May once the soil has warmed at a depth of 2cm (¾") and a distance of 90cm (36") apart. Sow 2 seeds per hole and thin out the weakest seedling per station after germination. Ideally grow under cloches until squash plants are established.

Thompson & Morgan strives to ensure that all its plants are delivered to you in the perfect condition for planting. While the majority of our nursery plants cope well with slight delays in intransit, sadly, the time it takes to deliver to certain locations in the UK means that we can't guarantee this for some of our smaller plug products and tender bedding and vegetable lines, which do not respond well to the extra journey time. So regretfully while we offer the majority of our live plant offering nationwide, we are unable to ship plugs, begging plants and tender vegetable plants to the following areas: HS, IV41-IV49, IV51, IV55-56, KW15-KW17, PA34, PA41-48, PA60-PA78, PA80, PH40-PH44, TR21-TR24, ZE1-ZE3
